Abstract

The invention provides an image processing method based on multiple threads, computer equipment and a storage medium. The method comprises the steps that a main thread creates multiple decoding sub-threads; the main thread sends a decoding instruction to the plurality of decoding sub-threads, so that the plurality of decoding sub-threads decode each frame of image in each decoding task at the sametime according to the decoding instruction to obtain a target decoded image set corresponding to each decoding task; the main thread controls a graphic processor to perform image recognition on eachframe of image in the target decoded image set to obtain a detection result set of the target decoded image set; the main thread performs data analysis on all detection result sets obtained in the current time period to obtain an image analysis result of each decoding task in the current time period; therefore, the problems of low processing speed and low processing quality of a video image processing method in the prior art are solved, and the requirement of a user for real-time processing of the video image is met.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a multithread-based image processing method, computer equipment and storage media. Background technique [0002] At present, in the image processing process, the image processing is generally performed on the central processing unit through a single thread, and since the processing speed of the central processing unit is proportional to the number of pixels in the image, it is difficult to process images with high resolution and deformation. Sometimes the processing speed and processing quality are not ideal; especially when image processing is performed on multiple input sources, it not only increases the processing burden of the central processing unit, but also has a long waiting time. [0003] It can be seen that the processing speed of the video image processing method in the prior art is relatively slow, and cannot meet the user's demand for real-time processing of...
