Abstract

The invention belongs to the field of railway tract detection and relates to a dynamic acquiring device and method for ballastless track marks CPs III of a high-speed railway. The acquiring device provided by the invention consists of a rail car, an encoder [1], a control trigger [2], a first high-performance industrial linear array camera [3], a second high-performance industrial linear array camera [4], a second laser illuminator [5], a first laser illuminator [6], a computer, a camera bracket [8] and a power source. The acquiring method provided by the invention comprises the following steps of: acquiring linear array images, carrying out coordinate transformation and calculating relative positions between the marks CPs III and the rail car. According to the invention, the relative positions between the CPs III and a track detecting device can be dynamically acquired, the working time for track detection is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to railway detection technology, and relates to a dynamic acquisition device and acquisition method for high-speed railway sign CPIII. Background technique [0002] The mark of the ballastless track of the high-speed railway mentioned in the present invention is CPⅢ point, which is used to control the laying shape of the ballastless track of the high-speed railway. Such marking points generally appear in pairs on both sides of the ballastless track, 3 to 4m away from the center of the track. On the main line, CPⅢ is set on the cement foundation piles on both sides of the railway, and appears once every 50-60m. In bridges or tunnels, CPⅢ is installed on the anti-collision walls on both sides of the railway, and appears once every 120m. Since the position of CPⅢ has been determined, obtaining the relative position of CPⅢ point and the rail car is of great significance for the detection of track geometric parameters and fault locat...
