Abstract

The invention provides a human body temperature measurement method, device and system and electronic equipment. The method comprises the following steps: acquiring a visible light video frame sequenceand an infrared video frame sequence corresponding to the same field of view; performing object detection on the visible light video frame sequence to obtain a visible light video frame marked with avisible object detection box, and performing object detection and tracking on the infrared video frame sequence to obtain an infrared video frame marked with an infrared object detection box and infrared trajectory information of the same object; and selecting a high-quality detection box corresponding to the first object based on the infrared track information of a first object, and searching atarget object detection box matched with the high-quality detection box from visible object detection box marked in the visible light video frame to determine the temperature of the first object. Human body temperature measurement is carried out based on the visible light video frame sequence and the infrared video frame sequence, the temperature measurement accuracy is guaranteed, in addition, workers do not need to get close to a measured target to carry out temperature measurement, and the labor cost is reduced to a certain degree.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a human body temperature measurement method, device, system and electronic equipment. Background technique [0002] Long-distance human body temperature measurement usually uses infrared temperature measurement technology, based on an infrared camera to collect a specific area in the human body image, and the maximum temperature in the specific area is taken as the human body temperature. [0003] In order to improve the accuracy of long-distance temperature measurement, related technologies usually use the technology of combining visible light and infrared temperature measurement. In this temperature measurement method, the target area is determined on the visible image through object detection technology, and then found in the infrared image For the infrared region corresponding to the target region, the temperature of the infrared region is used as the temperature mea...
