Popis:	In this paper analysis of accuracy of determining the coordinates of points on the plane template in the shape of rectangle is presented. These points lie at the corners of squares with side of 8 mm. Images of these points were obtained using Edimax IC-7100P camera from three different points of view and analysed. Position and orientation coordinates of camera relatively to the reference system were calculated. Coordinates of points on the ideal image (without optical distortions) were determined. After reading from the image real coordinates, optical distortion model coefficients of the camera were calculated. After that, errors caused by optical distortion were determined. Next, coordinates read from the image were corrected and coordinates of observed points in the reference system were calculated. Finally, calculated coordinates were compared to them real values and them maximal differences were determined.
