Track ballast bed foreign matter detection system and method based on background data comparison

The invention provides a track ballast bed foreign matter detection system and detection method based on background data comparison. According to the invention, foreign matter detection is realized based on a background data comparison mode, various foreign matters appearing on the line can be effectively detected, model training through early-stage acquisition of a large batch of data is not needed, the detection capability of foreign matters not appearing is relatively strong, and continuous optimization can be realized in the actual operation process of the line, so that the detection efficiency is improved. And the detection accuracy and stability are ensured. 本发明提供了一种基于背景数据对比的轨道道床异物检测系统及检测方法。本发明所提出的基于背景数据对比的方式实现异物检测，对于线路出现的各种异物均能有效检出，不用通过前期采集大批量数据进行模型训练，比对未出现的异物检测能力较强，并可在线路实际运行过程中，不断优化，保证检测的准确与稳定。
