This paper presents a method of “capturing” an object and reconstruction trajectory. It based on digital processing of a stream of optical images and depth maps from an RGB-D camera. This method relies on statistical processing and it possible to capture any objects, not only some type as neuro-algorithms. Reconstructed of trajectory performs in the field of view of RGB-D camera. Such video systems can be used for implementation to a covert scanning scheme of movement person. It will focusing radio wave or optical thermal sensors on the surface of a moving person’s body. The result of the algorithm is an object depth map, which represents the distance to each point of the visible surface of object.
