Background
In recent years, with the development of the consumer electronics industry, the 3D camera having the depth sensing function is receiving increasing attention from the consumer electronics world. The more mature depth measurement methods at present are structured light schemes and ToF techniques.
The tof (time of flight) technique is a 3D imaging technique that emits measurement light from a projector and reflects the measurement light back to a receiver through a target object, thereby obtaining a spatial distance from the object to a sensor from a propagation time of the measurement light in the propagation path. Common ToF techniques include single point scanning projection methods and area light projection methods.
The structured light three scheme is based on the optical triangulation measurement principle. The optical projector projects the structured light with a certain mode on the surface of the object to form a light bar three-dimensional image modulated by the surface shape of the object to be measured on the surface. The three-dimensional image is detected by a camera at another location to obtain a two-dimensional distorted image of the light bar. The degree of distortion of the light bar depends on the relative position between the optical projector and the camera and the object surface profile (height). Intuitively, the displacement (or offset) displayed along the bar is proportional to the height of the object surface, the kink indicates a change in plane, and the discontinuity indicates a physical gap in the surface.
