Embodiment Construction

[0044] Further description will be given below in conjunction with the embodiments and accompanying drawings.

[0045] A robust moving target detection and tracking image processing system, including a digital signal processor with DSP as the core, a CCD camera, and a PC. One end of the digital signal processor is connected to the CCD camera, and the other end is connected to the PC. The image processing system Perform the following steps:

[0046] Step 1: Acquisition of video data: the analog video signal input by the digital signal processor from the camera CCD is digitally collected by the analog-to-digital converter, and then transferred to the designated memory buffer space for processing;

[0047] In step 2, the digital signal processor reads in the collected digital video sequence frame by frame, and uses the improved mixed Gaussian background model to detect moving objects on the frame sequence in step 2;

[0048] Step 3 performs denoising and shadow removal on the de...

Abstract

The invention provides a robust motion target detecting and tracking image processing system. The system comprises a digital signal processor taking DSP as a kernel, a CCD camera and a PC, and executes the following steps of: acquiring video data; reading acquired digital video sequences frame by frame by using the digital signal processor; performing motion target detection on the frame sequences in the last step by adopting an improved mixture Gaussian background model; performing removing noise and shadow from the detection result in the last step; tracking the detected motion target; and transmitting and displaying the processed result to a user for processing, wherein adoption of the improved mixture Gaussian background model comprises the following steps of: performing background model initialization on the input video frame to establish a background model; subtracting the current frame from a background picture; binaryzing a foreground picture; morphologically filtering to remove the noise; introducing an accelerating factor and a smooth equation to update the background model; and converting the background into an image format for display.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and in particular relates to a robust moving target detection and tracking image processing system, which can detect and track abnormal moving targets in input video signals. Background technique [0002] DSP (Digital Signal Processor) is a microprocessor, a device that processes a large number of digital signals. Not only is it programmable, but its real-time running speed can reach tens of millions of complex instruction programs per second, far exceeding that of general-purpose microprocessors. It is an increasingly important chip in the digital electronic world. DSP is widely used in the field of image processing because it is easy to meet the requirements of large amount of calculation, strong real-time performance, and high data transmission rate in image processing, and the powerful multimedia interactive capabilities of computers. [0003] Moving object detection refers ...
