According to the requirements of camouflage net breakage detection in testing ground, the harm of camouflage net breakage, detection principles, testing layouts and the statistics method of breakage parts based on image processing are analyzed and researched. And a detection system of camouflage net breakage based on dual spectrum imaging is designed. Research results show that the system is reasonable in design, can be used for remote non-contact monitoring, can effectively detect the breakage states of camouflage net, which is used to evaluate and maintain the breaka ge states of camouflage net.
