Embodiment Construction

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0027] see figure 1 , the inspection inspection system includes a mounting frame 8 on which a plurality of light sources 1 and a plurality of cameras 3 located above the target 9 are symmetrically installed. Both the light source 1 and the camera 3 are connected with the host computer 7 . When the mounting frame 8 runs along the target object 9 at a certain speed, the light source 1 emits light to illuminate the target object 9; the camera 3 takes images of the target object 9 to obtain an image of the target object. Afterwards, the camera 3 sends the target image to the host computer 7, and the image processing system in the host computer 7 analyzes and processes the received target image.

[0028] In other embodiments, the mounting frame 8 is no...

Abstract

The invention provides a perambulated inspection system and method, wherein the perambulated inspection system comprises an installation frame, an upper computer, a plurality of cameras and a plurality of light sources; the cameras and the light sources are arranged on the installation frame; the installation frame is arranged above a target object and can move relative to the target object; the light sources are used for irradiating the target object; the cameras are used for shooting target object images so as to obtain target images; the cameras are used for sending the target images to the upper computer; and the upper computer is used for analyzing and processing the target images. According to the perambulated inspection system and method, disclosed by the invention, the effects of high efficiency on track perambulated inspection, accurate track defect positioning and high accuracy on defect size inspection can be achieved.

Description

technical field [0001] The invention relates to the field of railways, in particular to a patrol detection system. In addition, the present invention also relates to a method for performing patrol detection by providing the above patrol detection system. Background technique [0002] Track surface scratches, sleeper cracks, missing and damaged rail fasteners have brought great hidden dangers to the safe operation of railways. At present, domestic track inspection and detection are mainly visual method and mechanical contact measurement method. [0003] Among them, the visual method relies on a large number of experienced track workers to visually inspect the track. However, this method is inefficient and cannot measure the exact value of the track defect size. The mechanical contact measurement method also has the problems of low measurement efficiency and low accuracy of the size of the scratch defect on the track surface. Contents of the invention [0004] The object...
