Rail contact network spatial position detection method

Abstract

The invention provides a rail contact network spatial position detection method, which is applied to a photoelectric measurement system device 1, and comprises the following steps: an original image is acquired through an area-array camera 11 and a line laser 13, and the original image is sent to an image computer 12; the image computer 12 performs image processing on the original image to obtaina connected domain where the overhead line system line is located; an image segmentation method is adopted to segment a connected domain where the overhead contact line is located to obtain an actualarea where the overhead contact line is located; a gray gravity center coordinate of an area is calculated where the actual contact network line is located by using a gray gravity center method; the gray gravity center coordinate is converted into an image coordinate to obtain a contact network space coordinate; and spatial position parameters of the rail contact network are calculated according to the contact network spatial coordinates.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, and in particular relates to a method for detecting the spatial position of a non-contact track catenary. Background technique [0002] The pantograph of the electric locomotive relies on the catenary erected along the railway to continuously obtain the electric energy for operation. Since the electric locomotive pantograph is in sliding contact with the contact wire, there will be a certain lifting force on the contact wire during normal operation, which will lead to separation from the contact wire when it reaches a certain speed, and the contact suspension has different degrees along the span. difference. The catenary is an open-air device, and it will shift or dance under the action of strong wind, and in some cases, it will cause a bow failure. If the pull-out value is too small, the purpose of uniform wear of the slide plate and prolonging the life of the pantograph cannot...
