Abstract [eng] This article presents the method for reduction of image distortions, produced by camera tilt. It exploits camera orientation angles, obtained from accelerometer, and a distance to the object measured by ultrasonic sensor. The structure and operation of designed and implemented devices are analysed. A mathematical model for perspective distortion reduction is described. The proposed model was implemented in MathWorks Matlab software package using Image Processing toolbox. As the indicator of a reconstruction degree correlation coefficient between images, captured with direct camera, and a reconstructed image, which was captured with a tilted camera is used. Achieved results are compared with results, which show Radon transformation for rotated image reconstruction and four corners method for images with perspective distortion reconstruction.
