IWR6843AOP: Please tell me how to use DPIF_PointCloudSpherical and DPIF_PointCloudCartesian properly.

Hello,

I'm evaluating Area Scanner and Out of BOX,

but I'm wondering about the difference in UART output format.

In the Out of Box example, UART is output in DPIF_PointCloudCartesian format,

but in the AreaScanner example, UART is output in DPIF_PointCloudSpherical format.

What are the advantages and disadvantages of this different format?

    Hello,

    This is a great question, thanks for asking. If you were to only compare Cartesian and Spherical formats, then it is up to the programmer for which format they would like to use. The coordinate systems can simply be converted to each other. 

    However, with regards to Area Scanner, PointCloudSpherical is required because this point cloud format is used in the GTRACK algorithm. The GTRACK algorithm will not work with PointCloudCartesian coordinate system. So, the PointCloud format is converted to Spherical and then sent to the GTRACK algorithm.
