Problems solved by technology

[0002] At present, the infrared temperature measurement system has been deeply developed in many fields, especially when measuring in some high-risk environments. However, the existence of infrared temperature measurement camera distortion directly affects the credibility of the data collected by the system; The imaging clarity of thermal cameras is not as good as that of visible light, so they often need to be used together, so it is of great significance to study infrared calibration technology

Abstract

The invention discloses an automatic calibration method of a mobile infrared temperature measurement system, and the mobile infrared temperature measurement system comprises a fixed-focus visible light camera, a fixed-focus infrared camera, a rotatable pan-tilt, a laser radar, and a mobile device, wherein the visible light camera and the infrared camera are installed on the mobile device with thelaser radar through the rotatable pan-tilt; and the visible light camera and the infrared camera have the same rotation effect and a part of overlapped view field relative to the rotatable pan-tilt. The automatic calibration method comprises the following steps: calibrating the relative positions of the visible light camera and the infrared camera, and calibrating the relative positions of the laser radar and the visible light camera of the rotatable pan-tilt at different rotation angles, to obtain the real-time relative positions of the laser radar and the infrared camera. According to the method, the external parameter calibration of the visible light camera and the infrared camera can be effectively completed, so that the calibration of the two cameras does not interfere with each other, and the calibration efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of computer vision. More specifically, the invention relates to an automatic calibration method for a mobile infrared temperature measurement system. Background technique [0002] At present, the infrared temperature measurement system has been deeply developed in many fields, especially when measuring in some high-risk environments. However, the existence of infrared temperature measurement camera distortion directly affects the credibility of the data collected by the system; The imaging clarity of thermal cameras is not as good as that of visible light, so the two are often used together. Therefore, it is of great significance to study infrared calibration technology. In order to improve the coverage of the infrared temperature measurement system, the infrared temperature measurement camera can be installed on the mobile device, and equipped with a rotatable pan / tilt to cover the environment and equipmen...
