Device and method for near-infrared human pose detection

Abstract

The invention provides a device and a method for near-infrared human pose detection. The device comprises a microprocessor, a wireless range finding module, a near-infrared camera module, and an infrared LED lamp. The infrared LED lamp is used to compensate background light of the camera module, a user head outline image is acquired, and the range finding module is used to detect distance, and human postures are accurately calculated. The device and the method are high in measuring precision, simple in detection, fast in detection speed, and low in cost.

Description

technical field [0001] The invention relates to a near-infrared human body posture detection device and method, belonging to the technical field of biological identification. Background technique [0002] Human pose detection refers to determining what pose the human body is in by detecting the human body. Most of the pose detection in the prior art uses a camera to collect images, and then uses image analysis to distinguish the parts of the human body in the image. position, such as face recognition, etc., and then judge the posture of the person based on this, for example: whether the tested person is sitting or standing. This kind of detection requires the image collected by the camera to be relatively clear and of high resolution to be judged, and because the recognition method needs to process image data, it has high requirements on the processor, high cost, and the timeliness of information processing is relatively high. Difference. [0003] In the prior art, there i...

Problems solved by technology

This kind of detection requires that the image collected by the camera is relatively clear and the resolution is high to make a judgment, and because the recognition method needs to process image data, it has high requirements for the processor, high cost, and the timeliness of information processing is relatively high. Difference

[0003] In the prior art, there is also a method of using ultrasonic or infrared to detect the human body, but this method can measure the approximate distance, but cannot accurately obtain the distance of specific parts of the human body, so the pose of the human body cannot be accurately obtained
