Abstract

The present disclosure relates to a calibration method and device, and a temperature measurement face recognition device. The method includes: in a calibration mode, collecting a thermal infrared image and a color image corresponding to a calibration reference object at a calibration position, and the calibration reference object A face image is set, and a heating body is set at a preset position of the face image; the coordinates of the highest temperature point corresponding to the thermal infrared image are determined; the preset of the face image in the color image is determined The coordinates corresponding to the position; according to the coordinates corresponding to the preset position of the face image in the color image, and the coordinates of the highest temperature point in the thermal infrared image, establish the coordinates and color of the highest temperature point in the thermal infrared image The calibration relationship of the coordinates of the preset position of the image. The embodiments of the present disclosure can improve the calibration efficiency.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a calibration method and device, and a temperature measurement face recognition device. Background technique [0002] The dual light thermal imager has both color imaging (RGB (Red\Green\Blue, red\green\blue) imaging) and thermal infrared imaging functions. Color imaging is used to identify objects or people, and thermal infrared imaging is used to measure the temperature of objects or people. [0003] Because the camera for color imaging and the camera for thermal infrared imaging are installed in different coordinate positions, and there are manufacturing and assembly errors for each camera, the images captured by the two cameras cannot be in one-to-one correspondence. Therefore, it is necessary to calibrate the color imaging and thermal infrared imaging of the dual light thermal imager. SUMMARY OF THE INVENTION [0004] The present disclosure proposes a tec...
