Required characteristics of an image processing algorithm of videopositioning system for the objects in urban environment, using the contours of area relief and a digital map are substantiated. The aim is to design the algorithm of video processing for the purpose of positioning in urban areas with the characteristics providing positioning error within 3 m. An algorithm of area relief contour detection in an urban environment image obtained by camera is offered. It is shown that the average angular edge detection error of urban area relief is less than 2 degrees, providing positioning error RMS in 3 m limits using the set of cameras with a summary angle of view equal to 360 degrees, without using data about orientation system
in horizontal plane.

Key words: videopositioning, videonavigation, urban area, digital map, area relief contours.
