The invention discloses a human hand surface blood vessel non-visual detection device and method. The device comprises an infrared LED light source, an infrared LED light source controller, an infrared polarizer, an infrared analyzer, a large-view-field lens, an infrared CMOS camera, a hand fixing frame, a micro motor, a motor driver and a computer. The method comprises the following steps: the palm is placed in a fixing frame to be fixed, the infrared LED light source is turned on to illuminate the palm and wrist parts on the fixing frame, a computer drives the motor driver to control the micro motor to periodically rotate the infrared polarizer at a fixed angle, and meanwhile, the computer is utilized to control the infrared CMOS camera to take pictures and collect pictures after the micro-rotation of each fixed angle so as to obtain infrared polarization images irradiated by light at different polarization angles; all images acquired by the infrared CMOS camera are transmitted to the computer for processing, and blood vessel distribution non-visual images on the surfaces of the palm and the wrist are obtained through calculation. The invention has the advantages of easy operation, low cost, high imaging resolution and large view field.
Description
technical field [0001] The invention belongs to the technical field of optical medical imaging, in particular to a non-intuitive detection device and method for blood vessels on the human hand surface. Background technique [0002] A blood vessel is a series of tubes through which blood flows. Except for the cornea, hair, nails, dentin, and epithelium, blood vessels spread throughout the body. At present, vascular diseases are close to the first among the causes of death from human diseases. Current medical methods for blood vessel detection mainly include angiography and Doppler ultrasound. As an interventional detection method, angiography needs to inject a contrast agent into blood vessels for detection, which is easy to cause trauma to the human body and cause allergic reactions. Doppler ultrasonography is a new method for measuring the blood flow in the vascular cavity or the heart cavity, and can measure the speed and direction of the blood flow from the outside. D...
