Straddle type monorail image modeling rail inspection vehicle and inspection method

Abstract

The invention relates to a straddle type monorail image modeling rail inspection vehicle and an inspection method. The image modeling rail inspection vehicle comprises a trolley, digital cameras, an RTK device and scanners. The trolley is movably spanned on a track beam, and a moving station of the RTK device is fixed at a top of the trolley. Two outer sides of the trolley, corresponding to the track beam, are provided with a first support respectively, and a second support is horizontally arranged correspondingly to an upper portion of the track beam. The several digital cameras are arrangedon the first support along a vertical direction, and the several digital cameras are arranged on the second support along a horizontal direction. The scanners are arranged on the two first supports. The vehicle and the method have advantages that appearance three-dimensional image modeling of a straddle type monorail can be completed quickly and effectively, and a problem that a traditional scanning method is complex in operation is solved; a workload of an operator is greatly reduced on the condition of ensuring efficiency; and accurate detection of a monorail appearance size is completed incombination with a three-dimensional image model.

Description

technical field [0001] The invention relates to the technical field of railway track beam detection, in particular to a straddle-type monorail image modeling rail inspection vehicle and a detection method. Background technique [0002] With the development of science and technology, China's urban public transportation has undergone earth-shaking changes. From the bus to the subway, to the light rail, to the BRT, and then to the urban monorail train, all of them have accelerated the pace of urban development, and at the same time, various detection methods have gradually emerged, but at present, the detection technology of rail beam traffic mostly uses manual means , the efficiency is very low, and some automatic detection devices are too complicated to operate, and the auxiliary functions of the devices are too specialized, so that ordinary detection workers cannot operate quickly and skillfully. To fully master it takes a lot of time and effort to complete. It greatly inc...

Problems solved by technology

[0006] The beneficial effects of the present invention are: an array camera group and two three-dimensional laser scanners are provided, which greatly improves the scanning efficiency and quality, and then can quickly and effectively complete the three-dimensional image modeling of the appearance of the straddle-type monorail, solving the problem of The problem of complex operation of the traditional scanning method, and the diversity of functions of the control device, can quickly and efficiently complete the shooting of the single track that needs to be detected, the operation is simple, and the workload of the operator is greatly reduced on the premise of ensuring efficiency. The RTK device can detect the stability of the monorail alignment, combined with the 3D image model to complete the precise detection of the appearance and size of the monorail, as well as the detection of triangular pits and slopes on the surface
