Abstract

In this research, the accuracy and speed of obstacle detection in data fusion of ultrasonic and stereo vision have been improved. The smoothness assumption has been used in such a way that the responses are significantly improved without increasing calculation. In addition, with the development of the proposed method to run on the graphics card, the cross-checking process has been done without the need to change the reference image and without more calculation of the cost function. The results of this study show that the proposed method improved the quality of the responses compared to the previous study, and the obstacle detection rate in intelligent vehicles has increased to 41 pairs of frames per second. This processing rate is 477.40 times faster than the usual local stereo method and 33.77% faster than the previous study on the data fusion of ultrasonic and stereo vision.
