Abstract

The application discloses a depth image acquisition method, a depth image acquisition module and electronic equipment. The depth image acquisition module includes a first camera, a second camera, a third camera, a light projector and a processor. The first camera is used to take a preview image, and the processor acquires the ambient brightness of the scene according to the preview image. When the ambient brightness is greater than the preset brightness, the first camera takes a visible light image of the scene, the second camera takes a grayscale image of the scene, and the processor calculates a depth image of the scene according to the visible light image and the grayscale image. When the ambient brightness is lower than the preset brightness, the light projector projects infrared light into the scene to form a speckle pattern, the second camera takes a first speckle image of the scene, the third camera takes a second speckle image of the scene, and the processor A depth image of the scene is calculated according to the first speckle image and the second speckle image.

Description

technical field [0001] The present application relates to the technical field of three-dimensional imaging, and in particular, to a depth image acquisition method, a depth image acquisition module, and an electronic device. Background technique [0002] Electronic devices (such as mobile phones) are usually equipped with structured light depth cameras to obtain depth images of scenes. The light projector in the structured light depth camera projects infrared laser light to the outside world, and the infrared camera receives the infrared laser light reflected by the outside world to obtain a speckle image. The electronic device can calculate the depth information of the scene based on the speckle image and the pre-stored reference image. However, when the brightness of the external environment is high, the signal-to-noise ratio of the speckle image captured by the infrared camera is low, which will affect the accuracy of the depth information.
