Safety specification detection method based on laser radar

Abstract

The invention provides a personnel safety detection method based on a laser radar. The personnel safety detection method based on the laser radar comprises the following steps that scene information to be detected in the scene to be detected and a preset resolution of the laser radar are obtained, corresponding original parameters are matched in a preset laser radar parameter matching library according to scene information to be detected, a calibration object in the scene to be detected is detected by the laser radar according to the original parameters, a first measurement distance is obtained, an error between the first measurement distance and a preset standard distance is calculated, and an actual error value is obtained; and whether the actual error value is within a preset error range or not is judged, if not, the original parameters are readjusted according to the actual error value, the laser radar is controlled to detect a object to be detected in the scene to be detected according to the preset resolution and the original parameters, the object detection distance is obtained, and whether the object detection distance is larger than the preset safe early warning distance or not is judged. The personnel safety detection method based on the laser radar is high in positioning detection precision.

Description

technical field [0001] The invention relates to the field of safety regulation detection, in particular to a laser radar-based safety regulation detection method. Background technique [0002] At present, for personnel safety detection, the most important detection methods are manual supervision and camera monitoring. Especially for some high-risk scenes and restricted areas, the safety supervision of personnel is particularly important. In traditional detection methods, manual detection is obviously time-consuming, labor-intensive and inefficient. However, the accuracy of camera monitoring for security detection is not high, and the real-time performance is not strong enough. It cannot meet the needs of timely warning personnel and high-precision personnel positioning. At the same time, the video recognition algorithm used for cameras is relatively complicated, which is not conducive to large-scale promotion and rational utilization of resources. Therefore, the detection ...
