Depth camera device for mobile communication device

Abstract

The invention provides a depth camera device used for a mobile communication device. The depth camera device comprises an infrared emitter module which is configured to emit infrared light in a first wavelength range; and an infrared camera module which is configured to obtain image light and generate a depth image. The infrared camera module comprises an imaging lens which is configured to capture the image light, a first antireflection film being formed on the surface of the imaging lens, wherein the first antireflection film is used for enhancing transmitting intensity of the light in the first wavelength range; and a black-and-white image sensor which is configured to be aligned with the imaging lens and receive the image light from the imaging lens directly without passing through any light filter, and the black-and-white image sensor responds to the full-waveband image light directly received from the imaging lens and generates electrical signals. The depth camera device can improve photosensitive performance of the image sensor on the infrared light, saves power consumption, accelerates data acquisition speed and simplifies processing flow.

Description

technical field [0001] The present invention relates to a depth camera device, more specifically, to a depth camera device for mobile communication equipment. Background technique [0002] Nowadays, machine vision has quietly transferred from industrial control to the consumer electronics market. The demand for miniaturization and low power consumption has led to the fact that in the selection of hardware devices, it is usually impossible to choose a laser transmitter with high power consumption to meet the user's requirements for structured light intensity at a distance. Clear projection in the distance; it is also impossible to integrate a camera with a large-size photosensitive chip to meet higher photosensitive performance, larger dynamic range, and finer grayscale characteristics, so that the resolution accuracy under the hardware conditions of the industrial control field cannot be achieved. However, in order to achieve a good user experience, the application scenarios...
