Problems solved by technology

[0003] However, since the laser emission of the structured light emitter is controlled by the deep processing chip, and the deep processing chip is programmed once and cannot be changed, the emission driving function in the deep processing chip cannot be directly repaired when it fails or is not applicable , then it is impossible to guarantee the stable acquisition of depth images, which leads to poor stability of image application functions

Abstract

The embodiment of the invention discloses an image processing method and device and a storage medium. The method is applied to the image processing device and comprises: when a request instruction ofan image application function is detected, in response to the request instruction, transmitting acquired emission parameters to an emission driving module, and controlling an infrared camera to transmit a trigger signal to the emission driving module; in response to the trigger signal, controlling the structured light emitter to emit laser according to the emission parameters through the emissiondriving module, and transmitting a synchronization signal to the infrared camera through the emission driving module; in response to the synchronization signal, controlling an infrared camera to acquire a speckle image of the to-be-detected object; controlling the infrared camera to transmit the speckle image to the image processing module; and controlling the image processing module to perform depth calculation on the speckle image to obtain a depth image, and realizing an image application function based on the depth image.

Description

Technical field [0001] The embodiments of the present application relate to structured light technology, and in particular, to an image processing method and device, and a storage medium. Background technique [0002] At present, mobile devices such as mobile phones are increasingly adopting three-dimensional (3D, 3-Dimension) structured light technology to realize image application functions such as face unlocking, face payment, and 3D modeling. Specifically, the structure is driven by a deep processing chip The light transmitter emits light with certain structural characteristics and projects it on the object to be inspected. At the same time, the infrared camera shoots the object to be inspected and collects the speckle image of the object to be inspected. The depth processing chip receives the speckle image from the infrared camera. The depth calculation is performed on the speckle image to obtain the depth image of the object to be detected. The depth image reflects the spat...
