A Geographic Calibration Ranging Method for Single Station Optical Servo Monitoring

Abstract

A geographical calibration ranging method for single-station optical servo monitoring belongs to the field of monitoring. As the prior art cannot meet the normal work of all occasions, the method provided by the invention comprises the following steps of fixedly erecting a servo turntable optical monitoring device; marking an installation position of the servo turntable optical monitoring device on the map, generating 360-degree evenly divided azimuth distance data matrix points according to the installation position of the servo turntable optical monitoring device, marking the matrix points on the map, finding and aligning each matrix point by a photoelectric video according to ground object features on a ground remote sensing image map, calibrating all the matrix points, that is, azimuth pitch data of ground targets at different distances in different directions, and generating a reference data matrix; photodetecting and outputting azimuth and pitch data of the servo device; calibrating data matrix calculation by pitch and azimuth mapping according to the azimuth and pitch data, and outputting the distance value of the observation location. The invention realizes a simple distance measurement method by combining the terrain surface fluctuation characteristic data of the territory.

Description

technical field [0001] The invention belongs to the field of monitoring, in particular to a geographic calibration and distance measuring method for single-station optical servo monitoring. Background technique [0002] Photoelectric video surveillance is currently widely used in various industries, but photoelectric technology itself cannot accurately measure the distance of the monitored target or object, which brings some inconvenience to special applications in some industries, especially in the field of security monitoring. The distance data between monitoring devices is especially needed. Some optoelectronic devices will add some laser ranging devices to achieve ranging, but these laser ranging devices are expensive, and the distance measurement results must be stable and accurate. The application occasions and conditions also have certain requirements, not all occasions can work normally. Contents of the invention [0003] The present invention overcomes the defici...
