Abstract

The invention provides an infrared alarm system for rapid circumferential scanning directional distance measurement and a distance measurement method thereof. The system comprises an infrared imaging subsystem, a two-dimensional turntable subsystem, a laser distance measurement subsystem and a data processing subsystem, the two-dimensional turntable subsystem is used for driving the infrared imaging subsystem and the laser ranging subsystem to rotate and search to enter a circumferential scanning state; the infrared imaging subsystem is used for acquiring an infrared image sequence in a circumferential scanning process; the data processing subsystem is used for carrying out target detection on the infrared image, carrying out stable navigation building on a target after N circles of circumferential scanning, predicting azimuth and pitching angle information of the target during N + 1th circle of circumferential scanning, and controlling the two-dimensional fast reflecting mirror assembly to adjust a laser optical axis of the laser ranging assembly during N + 1th circle of circumferential scanning, thus a laser optical axis always faces a target direction and is kept unchanged in a process from laser emission to laser receiving; the laser ranging assembly is used for measuring the target distance. According to the invention, the directional distance measurement of the target can be completed in the circumferential scanning search process.

Description

technical field [0001] The invention belongs to the field of infrared warning, and in particular relates to an infrared warning system and a distance measuring method for fast circular scanning and directional ranging. Background technique [0002] When the infrared warning system searches for the target, it needs to scan the target. When the target is found, it needs to measure the distance of the target and obtain the three-dimensional information of the target. However, the existing infrared warning system can only measure the target to obtain the distance in the state of staring and tracking. information, so it is necessary to stop the rotation when measuring the distance, resulting in low search efficiency. Therefore, it is necessary to provide an infrared warning system that can measure the distance of the target in the process of weekly scanning. Contents of the invention [0003] The purpose of the present invention is to provide an infrared warning system and its...
