Abstract

The present invention discloses an image display method, device, electronic equipment, and storage medium. In the embodiment of the present invention, after the electronic equipment obtains the first captured image, according to the identification information of the first image, the stored video The second image is obtained from the first cache of the image obtained by decoding the code stream, the target object information is determined according to the second image, and the second image and the target object information are displayed. In the embodiment of the present invention, according to the identification information of the image, the second image corresponding to the captured first image is obtained in the first cache, without decoding the first image, which reduces the decoding time and improves the image display efficiency. To a certain extent, the problem of partial information loss caused by discarding images is alleviated.

Description

technical field [0001] The present invention relates to the technical field of image display, in particular to an image display method, device, electronic equipment and storage medium. Background technique [0002] The network hard disk video recorder NVR is connected with the front-end network camera IPC, and the IPC sends the video code stream to the NVR in real time, and when the IPC triggers a smart event, it will push the smart image to the NVR. There are generally two ways to push smart images: one such as figure 1 As mentioned above, background image + target small image, another such as figure 2 As shown, the coordinates of the background image + target small image area. After the NVR receives the smart image, it displays the smart image in real time on the display through the image list, such as image 3 shown. [0003] Currently, the smart image pushed by IPC to NVR is in JPEG format, and NVR needs to consume a certain amount of performance to decode JPEG. Fo...
