Argos3D - P100 Offset Calibration
Argos3D - P100 Manual Offset Calibration
If the absolute accuracy of your Argos3D - P100 is not to your satisfaction, or for any other reason, you can apply an offset to the distance data by following these steps:
- Place your Argos coplanar in front of a uniform white target
- Avoid extreme environmental light conditions or avoid light completely
- Plug the Argos' power and Usb cable
- Start the Application 'Argos3D - P100 Visualizer' Version 2.1.0 or higher
- Set the desired modulation frequency at which the Argos should be calibrated: In 'Command line' type 'SetRegister 130 <Hz>' (replacing <Hz> by the desired modulation frequency) and click 'Src cmd'
- The response is 'OK'
- Set the offset to zero: In 'Command line', type 'SetOffset 0 0' and click 'Src cmd'
- The response is 'OK'
- Check the amplitude in the center of the image by moving your mouse over one of the images: 'Statistics' shows the distance and amplitude
- Adjust the integration time in order to have an amplitude of approximately 3000 in the center of the image
- In 'Statistics', enter '50' in order to calculate the average over 50 frames
- Move your mouse over one of the two images in the center of the uniform white target
- After 50 frames without moving the mouse, the calculated average distance appears in the 'Statistics' section
- Substract that value from the real distance measured from the camera to the uniform white target
- The given offset can now be applied typing 'SetOffset 0 <mm>' (replacing <mm> by the offset in [mm]) and click 'Src cmd'
- In order to preserve the offset calibration beyond a device reset, the whole register map must be saved to flash by typing 'WriteConfigToFlash' in 'Command line and clicking 'Src cmd'
