Automatic positioning system and method of railway unmanned inspection vehicle based on image recognition

Abstract

The invention relates to an automatic positioning system for an unmanned railway inspection vehicle based on image recognition, which includes an unmanned inspection vehicle and an industrial computer. The unmanned inspection vehicle includes a chassis system, a lifting mechanism and a mobile platform system; The chassis system includes a chassis frame, on which the drive system and the first control cabinet are installed; the lifting mechanism includes an outer frame, a middle frame and an inner frame; the lower end of the lifting mechanism is installed on the chassis frame, and the lifting mechanism A mobile platform system is installed on the upper end, and an industrial camera and a second control cabinet are installed on the mobile platform system. The invention also discloses an automatic positioning method of the automatic positioning system of the railway unmanned inspection vehicle based on image recognition. This invention collects photos of catenary poles through industrial cameras, and their features are completely preserved and very reliable. Image recognition technology has been mature and has a wide range of applications. Therefore, it is also more reliable to use image recognition as the basis to realize automatic positioning of unmanned vehicles.

Description

technical field [0001] The invention relates to the technical fields of image processing and machine vision, in particular to an automatic positioning system and method for an unmanned railway inspection vehicle based on image recognition. Background technique [0002] The railway catenary is arranged above the railway line to provide power for electric locomotives and plays a key role in the normal operation of the railway. With the rapid development of my country's electrified railways, the reliability and stability of the railway catenary system is particularly important, so the regular inspection and maintenance of the railway catenary is also essential. At present, there are two main inspection methods in China: one is rickshaw ladder maintenance, which requires seven to eight people to carry inspection equipment and inspect the railway catenary one by one along the railway line, which is time-consuming and laborious. There are also potential safety hazards for personn...

Problems solved by technology

At present, there are two main inspection methods in China: one is rickshaw ladder maintenance, which requires seven to eight people to carry inspection equipment and inspect the railway catenary one by one along the railway line, which is time-consuming and laborious. There are also potential safety hazards for personnel; the second is to use large-scale fuel oil maintenance vehicles to complete the inspection of the catenary. The fuel oil maintenance vehicles must start from the station and cannot get on the rails from the middle section of the railway. It is inconvenient to deal with emergency faults and does not conform to the concept of sustainable development.
