Embodiment Construction

[0047] With the development of artificial intelligence technology, people's requirements for smart products are getting higher and higher. For example, in the smart monitoring system, when an illegal person breaks into the restricted zone, the face automatic detection and tracking system needs to notify the user as soon as possible , After receiving the notification, the user can respond immediately, thereby eliminating the shortcomings of the traditional monitoring system that cannot be dealt with in a timely manner. Therefore, the robustness, real-time performance and accuracy of automatic face detection and tracking technology need to meet relatively high standards. The face automatic detection and tracking system includes two main technical links, see figure 1 , the first is face detection, which is to find out the specific position and size of the face in the input image, and then face tracking, which predicts and updates the position of the face in the subsequent input i...

Abstract

The invention discloses a DSP-based automatic face detecting and tracking device and method. The method comprises the steps that a video camera acquires real-time analog video image data and transmits the real-time analog video image data to a decoding module through a video input port; the decoding module converts the real-time analog video image data into digital video image data; a DSP stores the digital video image data in a synchronous dynamic storage, wherein the DSP comprises a face detecting unit and a face tracking unit; the face detecting unit reads the digital video image data from the synchronous dynamic storage and performs face detecting processing on the digital video image data, so that a face region is obtained; the face tracking unit reads a digital video image for performing face tracking processing, so that a tracking result is obtained, and the face tracking unit transmits a tracking result image to an encoding module through an OSD FPGA module; the encoding module performs digital-to-analogue conversion on the tracking result image and transmits the converted tracking result image to a monitor so that the tracking result image can be displayed. The device and method have the advantages of being high in detecting speed and tracking accuracy.

Description
