Problems solved by technology

However, in the actual application process, the target area contained in the binocular stereo image pair is the most critical and effective part, and the image data of other areas in the calculation process will also affect the accuracy of the ranging results of the target area
In order to reduce the impact of image data in other areas and improve the efficiency and accuracy of distance measurement in the target area, it is urgent to propose a distance measurement method based on binocular stereo to solve the problems existing in the existing technology. The range measurement result of the target area obtained is inaccurate and other issues

Abstract

The invention discloses a ranging method based on binocular stereo. The method comprises the following steps: obtaining binocular image data after preprocessing; Obtaining binocular image data of a target region in the preprocessed binocular image data by a depth learning algorithm; Stereo matching method is used to calculate the spatial position of the target region. The scheme of the invention can obtain a more accurate spatial position of a target area by simple calculation.

Description

technical field [0001] The invention relates to computer technology, in particular to a distance measuring method and device based on binocular stereo. Background technique [0002] In the future era of artificial intelligence, vision-based target ranging technology will play an important role in areas such as unmanned driving, virtual reality, and robotics due to its low cost and wide application environment. In the common ranging method based on stereo vision, the acquired binocular stereo image pair is often directly processed to calculate the distance of each object in the image. However, in the actual application process, the target area contained in the binocular stereo image pair is the most critical and effective part, and the image data of other areas in the calculation process will also affect the accuracy of the ranging results of the target area. In order to reduce the impact of image data in other areas and improve the efficiency and accuracy of distance measur...
