Sensor Types and Technical Data
Information About the Sensor
4. Information About the Sensor Each configured ATOS sensor, in scan direction, has defined 3D areas within which a measuring object can be scanned. In the following, such a 3D area is called "measuring volume" (MV). The measuring volume determines the distance between sensor and measuring object and the set of lenses to be used.
In practice, depending on the measuring task, different measuring volumes might be required. Ideally, you have camera and projector lenses that are preadjusted to your measuring volume. In this case, you need to perform no or just very few steps for adjusting the sensor. A complete sensor setup is only required if the corresponding set of lenses has never been adjusted before or is decalibrated (wrong ad justments).
For a complete sensor adjustment, you need to adjust the angle relations of the cameras and set the focus and aperture of the lenses. Then, the complete system is calibrated by means of calibration panels or calibration crosses. If the measuring volume is adjusted successfully by calibration, you may start a measuring project.
The sensor adjustment is supported by the software. The software determines all necessary parameter settings. In order to achieve large, medium and small measuring volumes, the sensors can be adapted to the camera positions SO (Small objects) for small measuring volumes, 300 for medium measuring volumes and 500 for large measuring volumes, see table 4.1, with the help of exchangeable camera supports.

5. Lenses The lenses shown in this example may, in some cases, differ from those delivered in practice. Therefore, the statements made here have to be used correspondingly. All lenses are marked with L (left) or R (right) or P (projector). Left and right are defined from the sensor view in normal operating position. Never switch on the sensor if the projector lens still is equipped with the lens cap! Due to the high light output, the lens cap and the pro jector lens may be damaged!

Focal length. In this example 17 mm.
Aperture setting ring with manual locking screw. If no screw exists, locking is done by means of three hex socket head screws in the aperture ring. Note: In the example shown, aperture value 11 means aperture closed and aperture value 1.4 means aperture open.
For the projector lenses, the aperture value is fixed and cannot be changed. 3 0 9 0 2 1 0 2 c v e r _ n e _ 1 0 v e r _ s c _ s o t a
Select a set of lenses matching the required measuring volume and camera positions (e.g. SO, 300, 500), and screw it into the cameras and the projector. To avoid getting dirt into the cameras and the projector, always equip the devices with lenses or blind caps, even when they are switched off. When changing the lenses, fix the new lenses in place immediately. Screw in the lenses carefully by hand, lock the focus locking ring, if necessary, to ensure screwing in without any problems.

8. Sensor Setup 8.1
General
In order to adjust the sensor, the complete system including the ATOS software needs to be installed and the sensor must be equipped with a set of lenses matching the measuring volume and the camera position. For achieving all camera positions, three different camera supports can be used. Camera position 500
Camera position 300
Camera position SO
For each measuring volume (MV), the set of lenses are factorypreadjusted. If you have the respective set of lenses for each measuring volume, setting up the sensor is easy as you do not need to carry out all the steps referring to adjusting the focus and aperture! You always need to perform a complete sensor setup if, for example, the corresponding set of lenses has never been adjusted before or is decalibrated.
8.2
Measuring Volume
Use the table in section 4.1 to determine a measuring volume. You create larger measuring volumes with camera positions 500 and 300 and smaller measuring volumes with camera position SO (see table 4.2). Please check whether the cameras are in the correct position. How to change the camera positions is described in section 0.

Changing the Camera Positions (Step by Step)
In the following, we describe how to change the camera distance from 300 to SO. When you are changing the distance from SO to 300 or when you are changing to camera position 500, please proceed correspondingly. All camera supports have identical connecting elements.
The length of the camera connection cables are matched to the camera support when the system is delivered. If you received the support for camera position 500 or SO later, the connection cables might not be long enough. In that case, contact the GOM support or your local distributor.

How to Handle Calibration Objects
Sensor Calibration
10. Sensor Calibration Calibration is a measuring process during which the measuring system with the help of calibration objects is adjusted such that the dimensional consistency of the measuring system is ensured. During this process, the software determines geometrical parameters, for example position and orientation of each camera, based on the recorded camera images. In addition, the image characteristics of the camera lenses and the camera chips are determined. Based on these settings, the ATOS software calculates from the points of the calibration object in the 2D camera image their 3D coordinates. For the ATOS COMPACT SCAN SENSORS, three different calibration objects are used (panel with magnetic support, panel in the case, and cross). Generally, each measuring volume (MV) has its own calibration object. The table in section 4.1 informs you about which calibration object is required for your measuring volume. Crosses are used for system types for mobile operation, because the panels are too large for measuring volumes ≥ MV 250. Panels with a magnetic support are suitable for the smallest measuring volumes, e.g. MV 170 for camera position SO.
Calibration panel for MV 125
Calibration panel in the case for MV 300
Calibration cross for MV1200
If for a measuring volume you may use both, panel calibration and cross calibration objects, please use the more accurate panel calibration. Carry out the calibration only with the calibration object intended for your measuring volume.
10.1 How to Handle Calibration Objects Always handle the calibration objects with utmost care and prevent them from getting dirty and being scratched. Make sure you do not touch the surface of the calibration object if possible. After each use, duly accommodate the calibration objects. Clean the surface of the calibration object using the enclosed microfiber cloth from the standard tool box. Wipe the surface gently only. Never exert any pressure.

When is Calibration Required?
Before starting measurements for the first time, the respective ATOS measuring volume needs to be calibrated. Also, if the adjustment of the camera lenses or the position of the cameras with respect to each other is changed (e.g. when changing the camera positions 300, 500, SO), the system requires calibration again. If the system indicates a possible decalibration, you should perform a new calibration.
10.2.2
Prerequisites
We recommend letting the sensor warm up for approximately 30 minutes (camera and projector switched on), so that calibration can be carried out under operating conditions. A prerequisite for successful calibration is the correct setup of the sensor. The measuring object defines the measuring volume and thus the set of lenses to be used. Depending on the field of application of the measuring system (mobile, stationary), you either need to use a calibration panel or a calibration cross. The measuring distance to the calibration object has to be adjusted according to the measuring volume used, see the sensor configuration table in section 4.1 and 4.2. At the beginning of the calibration process, you need to enter the temperature into the software at which the calibration is carried out. Measure the temperature using a thermometer.
10.3 Calibration Using Calibration Panel CP 40 This section describes the calibration using the calibration panel CP40 and the ATOS COMPACT SCAN sensor on a stand. There are two types of this calibration panel: • •

Sensor Calibration
The CP40 calibration objects consist of black points on a white background. The larger points in the middle inform the ATOS software about the calibration panel type, e.g. calibration object CP 40 for measuring volume MV300. Each point was measured photogrammetrically in the factory. Always ensure that the calibration panel is clean (see section 10.3.1). For each calibration panel there is a CD containing the calibration data (file extension .calobj) and the certificate. A unique serial number provides for correct matching of calibration ob ject, certificate and calibration data.

Handling Instructions for Calibration Panel CP 40
The surface of the calibration panel is very sensitive. Therefore, never touch the surface directly with your hands. Calibration panels for measuring volumes MV 250 and larger remain in the case during the calibration process. Only the case cover is removed. Please remove the case cover carefully to prevent any damage to the surface of the panel. Clean the surface of the panel using the enclosed microfiber cloth from the standard tool box. Wipe the surface gently only. Never exert any pressure. Damaged points will not be used for calibration. Soiling and damages in the area of the larger calibration points in the middle may cause that the ATOS software does not identify the panel! If you use multiple ATOS COMPACT SCAN sensors, please check that the serial number of your calibration object matches the calibration data in the software. The software only checks the correct type of the panel but not the serial number. It is mandatory that the serial number of the calibration object is identical to the serial number of the calibration object in the ATOS software! Otherwise your measuring system may provide inaccurate measuring data!

Loading the Calibration Data
When using a measuring volume for the first time, you need to load the corresponding calibration data into the ATOS software and calibrate the sensor. If you purchased the measuring volume together with the complete ATOS system, the calibration data is already loaded. Insert the CD belonging to the calibration object into the computer and start the ATOS software. Choose Edit ► Application Settings ► Preferences ► Templates ► Calibration objects ► Import. Choose the calibration file with the extension .calobj from the CD. Now, the calibration object is selectable in the ATOS software.
10.3.3
Preparing the Calibration Process
When you want to calibrate a measuring volume, the sensor is already set up (see section 8) and the ATOS software knows which measuring volume and which camera position you want to use. Based on this information, the software determines the required focal lengths of the lenses. Open the calibration dialog in workspace Set Up ► Calibrate Sensor .

Maybe you are asked whether the settings are to be reset to the recommended calibration settings. This always happens when the calibration object has never been used before or it was used in connection with a different camera position (SO, 300, 500). Confirm the request with Yes. In the following windows, enter the current measurement temperature and accept the adjusted focal lengths (camera and projector lens). Place the calibration object with its case on the floor and use the stand to position the sensor at the measuring distance orthogonally over it. As the laser pointers are already adjusted to this distance (see section 8.4.2), you only need to move the sensor on the stand up or down until the two laser points become one. 3 0 9 0 2 1 0 2 c v e r _ n e _ 1 0 v e r _ s c _ s o t a

Calibration Result
At the end of the calibration process, the calibration result is shown. The green icon indicates a good calibration result. The red icon indicates an insufficient calibration result. In case of an insufficient calibration result, repeat the calibration and check the sensor settings (see 8.4), the correct camera lenses and ensure that the cameras and lenses are mounted tight. You reach the calibration results with Acquisition ► Sensor ► Calibration ► Show Calibration Information. As of software version V7.5 and higher, the calibration is saved in the ATOS COMPACT SCAN SENSOR.

Calibration with calibration cross CC30 in horizontal position
During calibration, the sensor configuration is determined. This means that the camera positions and the orientation of the cameras to each other are defined, and the image characteristics of the cameras are determined. Based on these settings, the software calculates from the points of the calibration object in the 2D camera image their 3D coordinates. The calculated 3D coordinates are then calculated back again into the 2D camera images. For the position of the reference points, this results in the so-called reference point deviation (intersection error). Page 33 (40)
Calibration Using Calibration Cross CC 30

The calibration cross also contains the information of two scale bars (one on each cross axis). The scale bar information is a s pecified distance between defined points. For each calibration cross there is the calibration certificate with the calibration data. You can also see the calibration data on the rear side of the cross.

The point surface of the calibration cross is very sensitive. Therefore, never touch the surface directly with your hands. Clean the surface of the cross using the enclosed microfiber cloth from the standard tool box. Wipe the surface gently only. Never exert any pressure. The calibration cross must be totally unfolded.
If you use multiple ATOS sensors, please check that your calibration object matches the calibration data you entered in the software. Make sure that the calibration cross does not touch the floor during the calibration process as otherwise deformation effects may lead to negative impacts during the calibration.
10.4.2

Calibration Using Calibration Cross CC 30
Sensor Calibration
Please follow the instructions until the end of the calibration process. In order to capture the entire measuring volume, you need to move the sensor during calibration. For this, the following general rule applies: You should move the sensor by 1/3 of the measuring volume height closer to the object and by 1/2 of the measuring volume height further away – in each case starting from the center of the measuring volume. After you recorded the last calibration image, finish the calibration with Compute.
10.4.5
Calibration Result
At the end of the calibration process, the calibration result and the scale bar deviation are shown with icons. The green icon indicates a good result. The red icon indicates an insufficient result. In case of an insufficient result, repeat the calibration and check the sensor settings (see 8.4), the correct lenses and ensure that the lenses are mounted tight. You reach the calibration results with Acquisition ► Sensor ►Calibration ► Show Calibration Information. As of software version V7.5 and higher, the calibration is stored in the ATOS COMPACT SCAN SENSOR.
10.4.6
Quick Calibration
If during a measurement it is indicated that the s ystem might be decalibrated (e.g. if you slightly knocked against the cameras), you may perform a quick calibration. You reach the software dialog with Digitize ► Sensor ►Calibration ► Quick Calibration. During this process, the calibration object needs to be placed into three positions - in the center of the measuring volume, further away from the sensor and closer to the sensor. These three new images are combined with the original calibration and thus a new calibration is calculated for the following measurements. This method is fast and can easily be used during recording a measuring project. However, the image characteristics of the cameras must not have changed! If, for example, you inserted new lenses, you need to perform a complete new calibration! The calibration cross must not have been taken apart during the last calibration and the quick calibration!
