文章对视频交通事件检测器进行了简单介绍,并对目前国内外相关厂家标称的检测精度提出了质疑,通过广泛的市场调研和实验室试验,对事件检测器的精度性能指标及影响因素进行了深入剖析,并阐明了误报率单一性能指标的不合理性,通过将其和系统阀值进行关联性分析,提出了误报率、漏报率双重指标的合理性,并对视频交通事件检测器的标准制定提出了进一步的建议。 The article briefly introduced the video traffic incident detector and questioned the nominal testing accuracy of the relevant domestic and foreign manufacturers. Through extensive market research and laboratory tests, the accuracy performance index and influencing factors of the event detector In the end, the author analyzed the unreasonableness of the single performance index of false positive rate and clarified the rationality of the double index of false positive rate and false negative rate rate by analyzing the relationship between the false alarm rate and the system threshold, The standard development of the detector made further suggestions.
