Description

technical field [0001] The invention is applied to camera image modules of artificial intelligence and biological intelligent terminal products, and relates to a micro biological intelligent structured light 3D image module integration system and a preparation method thereof. Background technique [0002] At present, the most common bio-intelligent image module integration system in the industry is mainly 2D image module system. This kind of product is usually a system composed of human sensor, LED fill light, and ordinary color camera module. The basic working principle is as follows: : When someone approaches, the human body sensor will first receive the information and feed it back to the main control system; the main control system will trigger the LED fill light to light up after obtaining the information; then the main control system will trigger the camera to start working; The face is photographed in 2D, and the feature data is extracted and analyzed; the main contro...

Problems solved by technology

[0003] However, this design scheme has the following problems and disadvantages: (1) A single camera is used, and the captured image can only be two-dimensional, without depth space information; (2) Because there is no depth information, the system cannot realize 3D Image shooting and reconstruction, the security level will be greatly reduced, and the chance of the system being deceived and attacked will be greatly increased; (3) The ordinary LED fill light is used, and the wavelength of the light is 650nm, which is included in the spectrum range of our visible light , so that the camera is easily affected by the visible light of the external working environment when taking pictures, resulting in the loss of the feature points of the captured image, which in turn causes the system to fail

These problems seriously restrict the experience effect of biological intelligent imaging system on consumers and cause hidden dangers of safety level
