Patent ID: 10880540

Abstract:
A 3D depth image acquiring method and apparatus, and an image acquisition device are provided. The method is applied to an image acquisition device comprising a VIS-NIR picture sensor and an infrared structured light projection component. The VIS-NIR picture sensor comprises a plurality of dot matrix units each having a blue light photosensitive component, a green light photosensitive component, a red light photosensitive component and an NIR photosensitive component distributed thereon. The method comprises: controlling the blue light photosensitive component, the green light photosensitive component, the red light photosensitive component, the NIR photosensitive component and the infrared structured light projection component to operate, to obtain an optimum NIR image and an optimum VIS image; and processing the optimum VIS image and a depth image which is obtained by performing calculation on the optimum NIR image using a 3D depth mode, to obtain a 3D depth image.
