There are many interference factors in clutter background,which leads to low accuracy and poor efficiency of slow moving target detection.A design scheme of multi feature fusion detection system is proposed.The hardware part is composed of preprocessing module,analog-to-digital conversion module and DSP module.Active low-pass filter is used to suppress the interference of high-frequency noise,and DSP is used to realize the effective control of other modules;The software part is composed of multi feature fusion detection module,communication interface module and storage module.The original image containing slow moving target is divided into several sub regions,and the complete local binary pattern(CLBP)histogram and tone histogram of each sub region are determined to match with the background model to realize the multi feature fusion detection of slow moving target;The test results are transmitted to the storage module through the USB interface to complete the storage of the test results.The experimental results of the system performance test show that the designed system can obtain the highest accuracy for the slow-moving target detection results under the clutter background with the least time.
