Road disease detection system and method capable of dynamically adjusting sampling frequency
The invention relates to the technical field of road disease detection, and discloses a road disease detection system capable of dynamically adjusting sampling frequency, comprising: a main camera; an auxiliary camera; the holder is used for installing the main camera and the auxiliary camera; a front end controller; the front-end controller comprises an image acquisition module which is used for acquiring shooting data of the main camera and the auxiliary camera. The auxiliary camera with the resolution lower than that of the main camera is added, the main camera carries out sampling at a low-speed frequency when the road surface state is good, the sampling frequency of the main camera is adjusted when the auxiliary camera finds that the road surface is damaged, and the damaged road surface is collected in an emphasized manner; therefore, the size of the data acquired by the main camera can be reduced, and a large number of pavement defect images are stored. Therefore, targeted analysis is realized, the detection precision is improved, and the detection computing power demand is reduced.
本发明涉及道路病害检测技术领域，公开了一种动态调整采样频率的道路病害检测系统，包括：主摄像头；副摄像头；云台，用于安装主摄像头和副摄像头；前端控制器；所述前端控制器包括：图像采集模块，用于采集主摄像头和副摄像头的拍摄数据。本发明通过添加分辨率低于主摄像头的副摄像头，在路面状态良好的时候主摄像头采用低速的频率进行采样，在副摄像头发现路面出现破损时候再调整主摄像头的采样频率，对破损路面进行重点采集，就可以既减少主摄像头的采集的数据的大小又保存了大量路面缺陷图像。从而有针对性的分析，提高检测精度、降低检测算力需求。
