AI Technical Summary
Technical Problem
When generating a binocular point cloud, the parallax of the near-view image in the left and right eye images is large, resulting in a low accuracy of the generated disparity map, which in turn affects the accuracy of the binocular point cloud.
Method used
By dividing the left-eye image and the right-eye image into four image areas, and scaling the second image area and the fourth image area containing the close-up image, the search space in the polar line direction is reduced, thereby reducing the parallax.
Benefits of technology
It improves the effect of stereo matching and the accuracy of parallax maps, thereby improving the generation speed and accuracy of binocular point cloud data.
