Multi-Camera configurations with the Intel® RealSense™ LiDAR Camera L515

There are a number of important reasons for wanting to combine multiple depth sensors for simultaneous live capture of scenes. For one, arranging depth sensors in an inward-facing configuration will allow for the simultaneous capture of both the front and back of objects, so that the real-time, whole surface volumes of objects can be captured. This volumetric recording can be used, for example, for Virtual- or Augmented-Reality “teleportation” and teleconferencing, or for scanning and measurement of all sides of an object. From a technology perspective, optical interference may occur if the L515 is arranged so that it captures scenes that consist of multiple simultaneously overlapping laser projections originating from independent L515 cameras. This means that L515 cameras that are spaced sufficiently far apart or oriented such that each camera cannot see the projected pattern from the other cameras, will NOT experience any interference, as shown in left two images of Figure 1 below. However, the right most image will lead to interference, and is the subject of this white paper.
