基于FFT图像差值在轮胎印痕识别中的研究

摘要

轮胎印痕识别对交通事故的现场勘测及事后侦查有着十分重要的作用.介绍了轮胎印痕识别在交通肇事逃逸案侦破中的具体应用,研究了基于FFT的图像差值原理,提出了基于FFT图像差值算法的轮胎印痕识别方法,并分析了具体的试验数据,结果显示,该方法有利于提高轮胎印痕识别的成功率,为快速查找肇事逃逸车辆提供了理论基础和科学依据.%Tire imprint recognition has important role for the scene investigation and subsequent investigation in traffic accident. Introduced the specific application of tire imprint recognition in traffic incident and run case detection, studied on FFT image difference principle, proposed tire imprint recognition method based on FFT image difference algorithm, and analyzed specific test data, the result showed that, the method proposed the success rate in tire imprint, and provided theoretical basis and scientific basis for search escape vehicles.
