The paper presents a solution designed to increase the measurement accuracy of the vision system for the large-sized bent pipes with one fixed camera. For this purpose, a model of perspective distortions has been developed for the outline of the object’s shape observed by the camera. Efficacy of the model was examined through a series of experimental measurements and their comparison with the model measurements of the pipe made on the coordinate measuring machine. During research, two versions of the program were used in parallel, where only one took into account the perspective distortions. The studies have confirmed the legitimacy and effectiveness of the used model improving the accuracy and repeatability of the measurement.
