Digital optical system is a normal camera internal screen which is divided into small squares of equal size (pixels), which as a result of photographing acquire averaged uniform color. At the same time, in the upper left part of the screen is highlighted the point of reference and plotted two semitransparent digital axis - left to right - OX and from top to bottom - OY. In some cases, the following question shows practical interest: - Can we identify the location of used digital optical system by the received image? It is known [1], that in the case where at the picture, the images that are not lying on one line of three point objects, the assigned problem can have no more than four decisions. There's also noted that the proposed method can be applied to autonomous navigation of aerial vehicles when in the space are pre-selected and localized the individual point objects. If the flight speed of the under review vehicle is material, and its autonomous navigation must be carried out fast enough. In this situation there is actual assignment of sufficient conditions for the uniqueness of the solution. Under these conditions we propose two such natural conditions, the second of which may have practical importance.
