Embodiment Construction

[0029] The method of the present invention will be further described below in combination with specific embodiments.

[0030] An OSD overlay method based on video detection, the main contents of which include:

[0031] 1. Video intelligent analysis and identification of portraits, and virtual wireframe marking of portrait areas; OSD system receives mobile phone number information and portrait area information obtained by mobile phone code detection of electronic fences in real time; the system automatically judges and dynamically avoids portrait areas, and then conducts mobile phone OSD character superposition of number information;

[0032] 2. The system automatically analyzes the size of the non-portrait area, preferentially selects the mobile phone number information with the largest non-portrait area superimposed, and performs OSD superposition in other non-portrait areas in turn;

[0033] 3. If there are portraits everywhere in the video image, and the non-portrait area can

Abstract

The invention discloses an OSD superposition method based on video detection. Existing methods may cover portraits in video images, resulting in detection and extraction of portraits by subsequent video intelligent analysis and even loss of key images of target portraits. The method comprises: firstly, carrying out portrait detection, and acquiring mobile phone number information by an electronicfence; dynamically tracking a moving tracking portrait target area of the portrait in a virtual frame form; and then selecting a non-portrait virtual frame area to carry out OSD character superposition by judging that the OSD of the mobile phone information needs to occupy space, and uniformly encoding the OSD character superposition information of the mobile phone number information and the videoimage to form a video stream for transmission, storage and application. According to the method, the portrait area recognized in video intelligent analysis is fully applied, clear target avoidance iscarried out in OSD character superposition, and shielding of portrait key information is completely avoided.
