A method, device, and storage device for automatically judging laser radar startup

Abstract

The invention provides a laser radar startup automatic discrimination method, equipment and storage equipment, the method comprising: firstly adopting an automatic exposure algorithm to adjust the exposure parameters of the camera; , perform Laplacian operation; perform binarization processing on the processed grayscale image to obtain a binary image; perform outlier detection on the binary image to count the number of stars; perform homogeneous normalization processing on the stars to obtain The threshold of the number of stars; finally, the maximum Rayleigh detection height of the lidar is exponentially fitted with the number of stars to obtain the current maximum Rayleigh detection height of the lidar; according to the maximum Rayleigh detection height of the lidar, it is judged whether it meets the start-up conditions of the lidar. The technical solution proposed by the present invention can realize the unattended operation of the laser radar, and realize the effect of intelligent discrimination through the photos taken by the camera, the number of stars that can be effectively identified and the maximum height of the laser radar when it is turned on.

Description

technical field [0001] The present invention relates to the technical field of laser radar, in particular to a method, device and storage device for automatic identification of laser radar starting up. Background technique [0002] Middle and upper atmosphere detection lidar (lidar) mainly detects the high-altitude atmospheric activities of 80km to 150km above the surface. The environment is also extremely harsh, and it is necessary to work in a sunny environment. Otherwise, in harsh weather environments such as rain, snow, and haze, solid particles and rain can easily damage precision equipment such as telescopes and laser mirrors. Lidar is an active detection method. During the detection process, the laser beam emitted and received scattered light, fluorescence, etc. need to be transmitted through the lower atmosphere. The transmittance of the lower atmosphere affects the observation results of the middle and upper atmosphere detection lidar. In this case, although the li...
