Abstract

An omnidirectional mobile unmanned platform method based on expressway tunnel crack detection, the platform includes a car body and a mecanum wheel arranged at the bottom of the car body; The compression springs are arranged in a figure-eight shape that gradually inclines from top to bottom. The Mecanum wheel is connected to the motor in the car body. The motor is connected to the motor drive. The motor drive is connected to the main control single-chip microcomputer. Nine-axis sensor module; the computer is connected to the laser radar (3) and camera; it solves the problem of fast, efficient and automatic tunnel detection, which is of great significance and reduces the waste of a lot of manpower and material resources in the detection of highway tunnel cracks , and the accuracy of crack detection will be greatly improved.

Description

Technical field: [0001] The invention belongs to the technical field of unmanned driving, and relates to the fields of machine vision, image processing, simultaneous positioning and mapping (SLAM), inertial navigation and electro-mechanical control, and in particular to an omnidirectional unmanned vehicle based on expressway tunnel crack detection. driving system. Background technique: [0002] Since the beginning of the 21st century, with the rapid development of the national economy, especially under the historical opportunity of the "7918" national expressway network planning and the development of the western region, the construction of highway tunnels has entered a period of rapid development. In the past ten years, the annual growth rate of road tunnels has reached 24%, which is much higher than the growth rate of roads and bridges. The importance of road tunnels has become increasingly prominent. At present, my country is the country with the most road tunnels and th...
