The invention belongs to the technical field of rail traffic disease detection, and provides a turnout switch rail close attachment detection method and system.The detection system is composed of an imaging control module, a visual imaging module, an image processing module and a carrying platform, the visual imaging module comprises two imaging units located over main steel rails on the two sides respectively, and the imaging units are connected with the imaging control module; the steel rail is imaged in the moving direction of the carrying platform, the imaging area covers the steel rail, the switch rail and the turnout, and a texture image and/or a depth image of the imaging area are/is obtained. According to the automatic detection system and method based on the visual detection method, the imaging unit in the visual imaging module is improved, and switch rail close contact insufficiency detection and gap quantitative measurement can be automatically achieved. 本发明属于轨道交通病害检测技术领域，提供了一种道岔尖轨密贴检测方法及系统，该检测系统由成
