Embodiment Construction

[0007] Combined with the diagram, the detailed description is as follows.

[0008] like figure 1 Hardware principle design diagram, during the design process of mobile phone video processing subsystem, refer to the TMS320DM6467 interface description to design the circuit between cache, DMA and interrupt, and then transplant Symbian or Window Mobile operating system and application programs, such as OpenGL ES and OpenCV. Refer to as figure 2 , establish the corresponding application program, and establish multi-processes or multi-threads for the corresponding functional functions. The entire motion tracking and recognition process can be established based on OpenCV and run in the background. The foreground program can build a 3D scene application based on OpenGL ES, and the 3D scene interaction can be driven by calling the motion interaction semantics obtained from the background, such as roaming and grabbing virtual objects. This can judge the effectiveness of the present i...

Abstract

The invention relates to a design method of a visual tracking interface on a 3G (The 3rd Generation Telecommunication) mobile terminal, which is the application of a machine vision technology on 3G mobile terminals. The interaction of motions and postures of human limbs with a 3G mobile phone is natural, but a vision algorithm on a traditional PC (Personal Computer) platform has large calculation cost and cannot obtain real-time interaction effects in the application of the mobile terminals. In the method, a TMS3 20DM6467 chip based on dicaryon is adopted to share the cost of a visual motion tracking and identifying algorithm, which obtains interactive real time on a mobile platform. An image sequence of limb motions is acquired by utilizing equipment such as a camera, and the like on the mobile platform on the basis of a visual user limb motion tracking interactive technology, static or dynamic limb characteristics are extracted and limb gestures or actions are identified through a visual algorithm so as to figure out the intention of a user and realize the man-machine interaction. The method has wide application prospect in the fields of intelligent interaction, recreational games, wearable computing, and the like of 3G mobile terminals.

Description

1. Technical field [0001] The design method of the visual tracking interactive interface on the 3G mobile terminal belongs to the technical direction of machine vision in the field of computer application technology. The invention covers image and video processing technology in computer vision and 3D interactive technology in augmented reality. 2. Background technology [0002] At present, the design scheme of the video processing subsystem of mobile phones is relatively mature, but it is still slightly insufficient for complex visual processing algorithms, and it is impossible to obtain real-time interactive effects in mobile terminal applications. The TMS320DM6467 launched by TI in 2008 is a digital media processor based on Da Vinci technology. The chip integrates ARM9 core, C64x+DSP core, high-definition video / image coprocessor (HD-VICP), video data conversion Engine and target video port interfaces designed to address a wide range of HD codes for commercial and consumer...
