Abstract

The invention discloses a binocular stereo vision measurement method, which includes target detection: positioning a first target detection frame, and obtaining initial image position information of the target; binocular positioning: obtaining relevant parameters of the binocular camera; Stereo matching: form the secondary parallax space and the three-dimensional information of each point in the image; object segmentation: finely segment the object to obtain the second object detection frame, and use the three-dimensional information in the second object detection frame Obtain the distance between the target object and the binocular camera or the distance protection target, etc. Through this scheme, the binocular stereo matching Lubang property can be improved, the cost aggregation efficiency in the process can be improved, and high-quality parallax can be quickly obtained, which is conducive to the rapid early warning of intrusion objects in the power grid, and the automatic early warning of transmission line intrusion objects .

Description

technical field [0001] The invention relates to the field of image processing, in particular to a binocular stereo vision measurement method. Background technique [0002] The following statements merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Condition monitoring of transmission lines in power systems is an extremely important task. At present, manual inspection and image monitoring are the most important methods in the condition monitoring of power transmission lines. However, these two methods require inspectors to be on duty on the spot or on the monitoring platform, which is inefficient and not conducive to intelligent early warning. In recent years, computer vision technology has developed rapidly. Vision measurement technology based on binocular stereo matching is also an important branch of computer vision technology that has been widely studied and applied. In order to realize the functi...
