3D structured light is a kind of 3D camera technology that uses optical means to photograph the three-dimensional structure of an object and perform in-depth processing. 3D structured light can be widely used in smart phones, digital cameras, security monitoring, assisted driving, smart robots, smart homes, new retail, housing design and other fields.
Traditional 2D cameras have limitations in the recognition of three-dimensional information such as size, volume, and distance. Taking face recognition as an example, under 2D technology, it is necessary to perform various actions in a scene with suitable light to be able to perform recognition. The recognition process is slow and there are safety hazards. The 3D camera to achieve stereo imaging has become a camera upgrade trend. 3D camera technology includes 3D structured light, TOF, and binocular stereo vision. 3D structured light and TOF are the mainstream technologies.
3D structured light and TOF are the mainstream solutions for 3D cameras. Both have their own advantages and disadvantages and can be used complementary. 3D structured light has high precision and high resolution at close range, suitable for static scenes, and can be used in front cameras; TOF recognition distance is long, fast response speed, suitable for dynamic scenes, and can be used in rear cameras. With the continuous acceleration of smart phone technology upgrades and update iterations, the application demand for new technologies is urgent, and the 3D structured light market has a good development prospect in the future.
