Vein development photographic device and three-dimensional panoramic model generation method thereof

Abstract

The invention provides a vein developing and photographing device. The vein developing and photographing device comprises a rack; a camera arranged at the top of the rack and capable of shooting a visible light two-dimensional image of a to-be-developed area of the patient; a synchronous driving device connected with a first lead screw and a second lead screw and used for driving the first lead screw and the second lead screw to rotate synchronously; a first infrared camera arranged at one end of a synchronous frame and used for shooting a to-be-developed area of the patient to obtain a first-eye two-dimensional infrared image; a second infrared camera arranged at the other end of the synchronous frame and used for shooting the to-be-developed area of the patient to obtain a second eye two-dimensional infrared image; a first laser arranged on the first infrared camera and capable of forming a first visible light spot on the surface of the patient; a second laser arranged on the secondinfrared camera and capable of forming a second visible light spot on the surface of the patient; and an image re-fusion processing module. The invention further provides a method for generating the vein developing and photographing three-dimensional panoramic model.

Description

technical field [0001] The invention relates to the technical field of vein development recognition, in particular to a vein development camera device and a method for generating a vein development camera three-dimensional panoramic model. Background technique [0002] Infrared imaging of veins plays an important role in medical assistance and biometric identification. In terms of medical treatment, venous imaging technology has been developed rapidly. According to relevant data, the success rate of normal adult venipuncture for the first time is 73%; the failure rate of the first two venipuncture for children is 58%; Generally speaking, the probability of "missing the needle" during venipuncture is 23-28%. Since there are many superficial subcutaneous tissues in the human body, it will be affected during the venipuncture process, such as: blood vessel depth, fat layer thickness, skin pigment content, etc. Affected by many factors, inexperienced or even experienced medical ...

Problems solved by technology

[0003] The invention application with the application number 201610980034.0 discloses a device and method for three-dimensional reconstruction of human superficial veins based on binocular stereo vision. The near-infrared light source and the camera are respectively placed on both sides of the acquisition object, effectively avoiding the skin surface structure and texture. The reflection of the light source can improve the imaging quality, but the fusion process of near-infrared light source and camera imaging is not easy to calibrate, and the calculation process is complicated, which increases the difficulty of implementation
