Device and method for moving target detection on mobile platform based on dsp+fpga

Abstract

The invention discloses a detecting device and detecting method for moving objects under a mobile platform based on DSP+FPGA. The device comprises a power source interface mixing panel which is of a sandwich structure, an FPGA preprocessing panel and a DSP image processing panel, wherein an image sensor is connected to the FPGA preprocessing panel, and the FPGA preprocessing panel and the DSP image processing panel are respectively connected to a displayer through video interfaces and respectively connected to an access gateway through network interfaces. The method comprises the steps that the FPGA preprocessing panel acquires image data collected by the image sensor, carries out preprocessing such as corner detection on the image data and then inputs the image data to the DSP image processing panel; the DSP image processing panel takes an optic center of a video camera as a center to establish a coordinate system, and converts the detection of the moving objects under the mobile platform into scene overall movement and independent movement of the moving objects under a static platform; the FEE dense subjection degree is quickly evaluated and determined through an FEE in an extreme line mode, the detection of the moving objects is finally completed, and a result is sent to the displayer. The detecting device and detecting method for the moving objects under the mobile platform based on the DSP+FPGA can achieve the detection of the moving objects under the mobile platform, and has the advantages of being high in precision and strong in stability.

Description

1. Technical field [0001] The invention belongs to the field of digital image processing and pattern recognition, in particular to a DSP+FPGA-based mobile target detection device and method thereof. 2. Background technology [0002] Automatic moving target detection technology is the key technology in the target search and tracking system, which provides preliminary information for the follow-up track correlation, target recognition and other technologies. In the traditional moving object detection system, the camera is usually stationary, and is widely used in video surveillance, traffic detection and other systems. Efficient estimation of scene disparity. [0003] Traditional methods generally use the epipolar geometric relationship between images under a moving platform, such as planar homography matrix, fundamental matrix, and trifocal tensor, to compensate or estimate camera motion. Among them, the homography matrix uses the mapping relationship between matching point...
