Real-time target tracking system based on DSP+FPGA framework

Abstract

Disclosed is a real-time target tracking system based on a DSP+FPGA framework. The system has a very good tracking effect on quick motion, scale change and certain fuzziness of targets, and satisfies the real-time performance and stability requirements of practical engineering. The system comprises a DSP control chip and an FPGA control chip. The system is structurally characterized in that a reset circuit, a serial interface chip, a decoder chip, an encoder chip and an SDRAM, which are connected with the FPGA control chip, are arranged outside the FPGA control chip, wherein the decoder chip is connected with an external camera module, and the output of the encoder chip is sent to a display system; and a FLASH chip is arranged outside the DSP control chip.

Description

technical field [0001] The invention is applied to the field of target tracking in weapons, and is specifically a real-time target tracking system based on DSP+FPGA framework. Background technique [0002] With the continuous improvement of our country's weapon development level, there are more and more weapons and equipment with high speed and high maneuverability. The relative movement of the model weapon is relatively large, and the target scale changes and the speed is fast, which is very robust. These require the target tracking system to have a higher processing speed and a more complex and stable tracking algorithm. [0003] The target tracking algorithm in engineering applications is limited by the embedded system. For those with more floating-point operations and a large amount of calculation, such as SIFT feature point matching, target tracking based on principal component analysis (PCA), and target tracking based on the snake model It is difficult to realize real...

[0003] The target tracking algorithm in engineering applications is limited by the embedded system. For those with more floating-point operations and a large amount of calculation, such as SIFT feature point matching, target tracking based on principal component analysis (PCA), and target tracking based on the snake model It is difficult to realize real-time processing on embedded systems, and existing engineering application mature center-of-gravity tracking and correlation tracking have the problem of tracking loss for complex situations.
