Three-Dimensional Vehicle Detection Algorithm Based on Binocular Vision
Stereo region-convolutional neural networks (Stereo R-CNN) algorithm has the characteristics of accuracy and efficiency. It has better detection performance in certain scenes, but there is still room for improvement in the detection of distant targets. In order to improve the vehicle detection accuracy of the binocular vision algorithm, an improved Stereo R-CNN algorithm is proposed in this paper. The algorithm uses deterministic network (DetNet) as the backbone network to enhance the network's detection of long-term targets; for the potential key points of the left and right eye views, the consistency loss function of the key points of the left and right views is established to improve the location accuracy of the potential key points, and then improve the accuracy of vehicle detection. Experimental results on the KITTI data set show that the performance of the algorithm is better than Stereo R-CNN, and the average accuracies of two-dimensional and three-dimensional detection tasks are improved by 1%-3%.
