Description

TECHNICAL FIELD

[0001] The present application relates to the field of infrared temperature measurement technology, in particular to an infrared temperature measurement device and equipment and method thereof. BACKGROUND

[0002] Gait recognition is a technology that combines computer vision, pattern recognition and video / image sequence processing. It identifies identity by analyzing the body shape and walking posture of a person, and has the advantages of non-contact, long distance and difficult to disguise, and is more advantageous than image recognition in the field of intelligent video monitoring.

[0003] With the development of science and technology, non-contact infrared human body temperature measurement technology has developed rapidly, with continuously improved performance and enhanced functions.
