Abstract
Results of studies on influence of the intensity of the appearance of users simultaneously using ToFcameras in the field of view on the probability of incorrect construction of a depth map are presented. The process of users appearing in the field of view is described by a spatial point Poisson distributed process with a given intensity. Simulation results using the Intel RealSense D455 camera are presented. Calculations are performed of the shooting region area where ToF-cameras can create mutual interference during multi-camera shooting. The duration of the signal is also evaluated, and the shutter speed of the deep chamber is determined. Based on the data obtained, the probability of incorrectly constructing a depth map is estimated and a graph of its dependence on the intensity of the appearance of users in the visibility area was constructed. Results of an experiment to determine the dependence of the amount of interference on the distance of intersecting cameras from the object are presented.
