Abstract

The invention provides an infrared double-station calibration method and calibration system. The calibration method comprises the following steps: respectively calculating differential position information through a first calibration assembly and a second calibration assembly according to a satellite positioning signal; the host of the first calibration assembly calculates the length of a double-station base line and the data of the relative position of the double stations according to the first differential position information and the second differential position information, and sends the data to the master station; the main station calculates a turntable direction angle of the main station aiming at the auxiliary station and an included angle between a turntable side angle zero degree of the main station and the due north direction according to the double-station base line length and the double-station position data, and sends the angle to the auxiliary station; and the auxiliary station sets a turntable azimuth angle zero position according to the included angle between the turntable side angle zero degree of the main station and the due north direction, so that the turntable azimuth angles of the auxiliary station and the main station are consistent. The method has the advantages of being high in positioning precision, good in environmental adaptability and the like, configuration and algorithm implementation are easy, operation is easy and convenient, the user experience is greatly improved, and the requirement for double-station rapid calibration of the infrared detection system is met.

Description

technical field [0001] The invention relates to the field of vehicle-mounted photoelectric equipment, and more specifically, to an infrared dual-station calibration method and a calibration system. Background technique [0002] The infrared detection system needs to detect the distance and relative position of the dual-station infrared sensors. Generally, the dual-station infrared sensors aim at each other to obtain the angular position of the other party's axis angle mechanical zero relative to itself; Manual input to complete the calibration of the distance and relative position of the two stations. This method has high requirements on visibility, both stations must be within the line of sight, and the environmental adaptability is poor; manual two-station ranging, the process is complicated and time-consuming. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] Aiming at the technical problems ...
