The embodiment of the invention provides an information overlapping display method, device and system and image processing equipment. The method comprises the following steps: acquiring character information acquired by information acquisition equipment; according to the determined display position used for displaying the character information, sending the character information and position information used for representing the display position to an image acquisition device, so that the image acquisition device superposes the character information on the display position of the acquired video frame in a layer form, and a superposed video frame is obtained; acquiring a superposed video frame sent by the image acquisition equipment; and displaying the superposed video frame. The system resources occupied by overlapping and displaying the character information can be effectively reduced.
Description
technical field [0001] The present invention relates to the technical field of video acquisition, in particular to an information superimposed display method, device, system and image processing equipment. Background technique [0002] The image acquisition device can collect the video data of the monitoring scene and transmit it to the image processing device for storage. Users can browse the video data stored in the image processing device according to their needs to obtain relevant information of the monitoring scene. But the image information in the video data may not reflect the information that all users are interested in in the surveillance scene. [0003] In order to enrich the information in the video data, other information acquisition equipment other than the image acquisition equipment can be used to collect the monitoring scene, obtain other information in the form of characters, and send the other information to the image processing equipment. When the user br...
