Problems solved by technology

The disadvantages of the prior art are: the CPU needs to register an additional way to monitor the camera data, which increases the consumption of memory; and the preprocessing is carried out in the CPU, which takes up a part of CPU resources; due to the limited CPU resources, using the prior art The solution will also delay the timing of sending to ADAS, which will cause the lag of the AR rendering screen and affect the user experience

Abstract

The invention discloses an image preprocessing method and device, an electronic device and a storage medium, and relates to the technical field of AR navigation. According to the specific implementation scheme, the method comprises: in response to a camera preview starting instruction, calling a pre-created drawing surface window through a CPU to obtain a current data frame collected by a camera;converting the current data frame into a preview texture corresponding to the current data frame through a drawing surface window; and sending the preview texture corresponding to the current data frame to the GPU, processing the preview texture corresponding to the current data frame through the GPU, and sending the processed preview texture to the ADAS through the CPU. According to the embodiment of the invention, image preprocessing can be realized without additionally registering one path of monitoring on the camera data by the CPU, CPU resources can be effectively saved, and the preprocessing speed is improved.

Description

technical field [0001] The present application relates to the field of computer application technology, and further relates to AR navigation technology, especially an image preprocessing method, device, electronic equipment and storage medium. Background technique [0002] Augmented Reality (AR for short) is also called mixed reality. It uses electronic technology to apply virtual information to the real world. The real environment and virtual objects are superimposed on the same picture or space in real time. AR provides a type of information that is different from what humans can perceive. It not only shows the information of the real world, but also displays the virtual information at the same time, and the two kinds of information complement and superimpose each other. In visual augmented reality, users can use the display to multiplex the real world with virtual graphics. AR is a technology that uses virtual objects to "enhance" the real scene. Compared with virtual ...
