SYNCHRONOUS TOF DISCRETE POINT CLOUD-BASED 3D IMAGING APPARATUS, AND ELECTRONIC DEVICE

摘要

The present disclosure provides a synchronous ToF discrete point cloud-based 3D imaging apparatus, and an electronic device. Said apparatus comprises a discrete light beam projector and a photodetector array imager; the discrete light beam projector is configured to project multiple discrete collimated light beams to a target object; and the photodetector array imager is configured to receive the multiple discrete collimated light beams reflected by the target object and to measure propagation time of the multiple discrete collimated light beams, so that depth data of the surface of the target object can be obtained. In the present disclosure, the discrete light beam projector projects multiple discrete collimated light beams to the target object, so that the photodetector array imager receives the collimated light beams reflected by the target object, thereby obtaining depth data of the surface of the target object, improving the power density of the light beams, and achieving a balance between a signal-to-noise ratio and a point cloud density, so that 3D imaging can be performed at a low cost, and with low power consumption and high precision.
