Embodiment Construction

[0064] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0065] The video generation method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 102 communicates with the server 104 through the network. The terminal 102 superimposes the video superimposed OSD information on the image to be encoded, performs video encoding on the image to be encoded with the OSD information superimposed, and obtains a video file. Wherein, the terminal 102 may be various devices such as a personal computer, a notebook computer, a smart phone, a tablet computer, and a portabl...

Abstract

The invention relates to a video generation method and device, computer equipment and a storage medium. The method comprises the following steps: receiving a to-be-coded image, detecting a preset target object and video superposition OSD information in the to-be-coded image; if the target object is shielded by the OSD information, traversing an image region matched with the OSD information in theto-be-coded image, superposing the OSD information to the matched image region, and performing coding to obtain a video image. By adoption of the method, the target object of the video image can be prevented from being shielded by the OSD information, so the situation that the target object cannot be displayed or extracted when the back-end device performs output display or image detail extractionon the video file formed by the video image is avoided.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to a Chinese patent application filed with the China Patent Office on June 13, 2019, with application number 201910509104.8 and titled "Video Generation Method, Apparatus, Computer Equipment, and Storage Medium", the entire contents of which are incorporated by reference in this application. technical field [0003] The present invention relates to the technical field of image signal processing, in particular to a video generation method, device, computer equipment and storage medium. Background technique [0004] In order to better display the shooting information of the camera, relevant information such as real time and shooting location can be superimposed on the video screen through the video overlay technology (OSD, On Screen Display). For example, superimpose relevant information on the local video signal, synthesize the OSD image signal, perform video encoding processing on the...
