    Hi Vedivedi975,
    The ROI of the DWS software depends on the L515 camera features. The L515 is projecting the laser IR beam outwards in a spherical shape, however, displays depth as a plane. Let’s consider for example an application that is scanning a wall at 9m distance from the camera. In this case, the distance from the camera at the center of the sphere is indeed 9m however the light that travels to the edge of the field of view horizontal to the center of projection, can be calculated as 9m divided by cos350 (horizontal field of view is 700 ), that’s 10.98m. The corner of the FOV is even further away. Since the max range specified for the camera is 9m, one should expect a reduction in plane projected FOV when approaching that range. L515 supports 10% ROI at 9m due to that specific reason.

    Check out the LiDAR L515 datasheet , page 8, Table 3-1 for the details of the camera specification.

    Thanks for your reply, I have already met this information from the datasheet, my setup height only goes up to 2-3 meters. The same setup height and ROI change dynamically (i.e. yellow bounding box in the stream), how do you determine the ROI region?

    Hi Vedivedi975.

    Sorry for the delay in replying to you. The ROI does not change dynamically unless you use the Static mode.
