OPT8241-CDK-EVM: Calibration depth mode

Malte Jeske
Prodigy 30 points

Part Number: OPT8241-CDK-EVM

Hello

We work withe OPT8241 CDK Evaluation Module and read depth informations with Voxel SDK from camera. The distortion correction by lens and pixel-wise phase offset calibration only works in point mode. Is there a way to get it work in depth mode or can you give me information of the internal calibration model.

Best regards

Malte

    Hi Malte,

    Distortions are corrected in the point cloud as well as the depth frames. An example code of the calibrations is given in github.com/.../calibration

    These are mainly for reference.

    Lens calibration is taken into account while computing the pixelwise phase offsets and then depth is calculated from this phase. So for a flat object, the phase would look like concentric circles. However, the depth would be the same for all pixels. You can see the difference from the phase image and depth image of a flat wall in VoxelViewer.
