Infrared temperature measurement imaging device and detection method thereof

Abstract

The invention discloses an infrared temperature measurement imaging device and a detection method thereof. The device comprises an infrared temperature measurement imaging module, a three-dimensional imaging module, a data processing module and a correction processing module. The infrared temperature measurement imaging module is used for acquiring two-dimensional temperature image data of a detected object. The three-dimensional imaging module is used for acquiring position data of a detected object surface. The data processing module is used for acquiring three-dimensional temperature data of the detected object surface according to the position data of the detected object surface, the two-dimensional temperature image data of the detected object and other parameters. The correction processing module is used for correcting the three-dimensional temperature data of the detected object surface according to a position relation of the detected object and the infrared temperature measurement imaging module and acquiring corrected temperature data. The device can acquire three-dimensional temperature distribution of the detected object. Through correcting the temperature of the detected object surface, the accurate temperature of the detected object surface can be acquired.

Description

technical field [0001] The invention relates to the technical field of infrared imaging temperature measurement, and more specifically, to an infrared temperature measurement imaging device and a detection method thereof. [0002] technical background [0003] Infrared thermal imager is a passive imaging temperature measurement instrument that uses infrared image detectors to convert invisible infrared radiation signals into visible images. It can directly measure the temperature and temperature distribution of the surface of objects, and convert the temperature distribution of objects into visible images The visual image is displayed on the monitor in grayscale or pseudo-color, so that the temperature distribution field of the measured target can be intuitively obtained. [0004] At present, a large number of infrared thermal imaging cameras are mainly composed of infrared imaging lens, infrared focal plane array (FPA), signal processing circuit, display and control, etc., w...
