ANALYSIS OF THE ACCURACY OF DETERMINING POSITION OF AN OBJECT USING AN OPTOELECTRONIC SURVEILLANCE SYSTEM
Considers the possibility of using an optoelectronic surveillance system to determine the location of an object – distance to the object and the direction to it. A geometric shape that has symmetry along at least one of the axes is used as a tag in the image to determine the position of an object. To process images coming from the camera, an algorithm was developed that provides both preprocessing of data (binarization, removal of noise component, selection of shape contours) and the subsequent search for a tag of a given shape. As a result of the experiments, the negative influence of the lens mounted on the camera on the accuracy of determining the position of an object at significant mutual angles between the camera and the tag was revealed. The value of this measurement error can be significantly reduced if the correction factors determined by the properties of an optical system used are additionally introduced into the algorithm.
