Laser radar startup automatic discrimination method and device, and storage device

Abstract

The invention provides a laser radar startup automatic discrimination method and device, and a storage device. The method comprises the steps: firstly employing an automatic exposure algorithm to adjust the exposure parameters of a camera; carrying out second-order derivation on the gray-scale map of the compressed image, and carrying out Laplace operation; performing binarization processing on the processed grayscale image to obtain a binarized image; carrying out isolated point detection on the binarized image, and counting the number of stars; carrying out similar normalization processing on the stars to obtain a star quantity threshold value; and finally, performing exponential fitting processing on the maximum Rayleigh detection height of the laser radar and the number of stars to obtain the current maximum Rayleigh detection height of the laser radar; and judging whether a laser radar startup condition is met or not according to the maximum Rayleigh detection height of the laserradar. According to the technical scheme provided by the invention, unattended operation of the laser radar can be realized, the number of stars and the maximum startup height of the laser radar can be effectively identified through pictures taken by the camera, and the effect of intelligent judgment is realized.

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...
