Problems solved by technology

[0002] The mobile terminal can be equipped with a depth camera and a display screen. The depth camera can be used to obtain the depth information of the object, and the display screen can be used to display text, patterns and other content. Usually, it is necessary to open a window on the display screen, such as forming a notch screen, so that the display The display area of ​​the screen and the position of the depth camera are staggered, and this setting of the display screen results in a lower screen-to-body ratio of the mobile terminal, and if the depth camera is set under the display screen, due to the influence of the display screen, the accuracy of the depth camera to obtain depth lower

Abstract

Disclosed are an image acquisition method, an image acquisition device, a structured light assembly, and an electronic device. The image acquisition method comprises the following steps of: controlling the structured light camera to receive the speckle image by diffracting the structured light diffracted by the display area of the display screen and directly incident after being reflected by the target object; Filtering a second measurement speckle in the speckle image to obtain a first measurement speckle; And acquiring a depth image based on the first measured speckle and the reference speckle in the reference image. The structured light projector and the structured light camera can be arranged under the display screen, and the influence of the display screen on the structured light canbe eliminated by filtering the second measuring spot in the speckle image, so that the depth image acquired by the electronic device is high in accuracy under the condition that the screen occupancy of the electronic device is high.

Description

technical field [0001] The present application relates to the technical field of consumer electronics, and more specifically, to an image acquisition method, an image acquisition device, a structured light component, and an electronic device. Background technique [0002] The mobile terminal can be equipped with a depth camera and a display screen. The depth camera can be used to obtain the depth information of the object, and the display screen can be used to display text, patterns and other content. Usually, it is necessary to open a window on the display screen, such as forming a notch screen, so that the display The display area of ​​the screen and the position of the depth camera are staggered, and this setting of the display screen results in a low screen-to-body ratio of the mobile terminal. If the depth camera is set under the display screen, due to the influence of the display screen, the accuracy of the depth camera to obtain depth lower. Contents of the inventio...
