The laser light source of handheld 3D scanning is an important laser for the development of science and technology in recent years, and its laser spot presents a multi-line laser that intersects with each other, which can be 2 multi-line laser crossings or 3 multi-line laser crossings, which is determined by the specific laser spot application case.
1. The principle of laser light source for handheld 3D scanning.
The laser light source of handheld 3D scanning mainly uses the shaping technology of the laser to change the direction of light propagation regularly through the DOE grating sheet to form a multi-line laser, and the laser obtains the three-dimensional shape information of the target object by emitting a laser beam to the target object and receiving the reflected light signal by the camera.
Structured light for handheld 3D scanners is a technology that uses 3D to sense and measure the shape and structure of objects. Structured light projects a specific light stripe or light point pattern to the target object, and then uses the camera to capture the deformed light pattern, and obtains the coordinate information of the object's three-dimensional shape by calculating the difference between the light patterns before and after the deformation.
