Problems solved by technology

In the cable duct, the robot often needs to complete the cable detection task while passing through the complex terrain environment, which brings great challenges to the mechanical structure design and software algorithm design of the robot
[0005] At present, the maintenance work of the cable duct is mainly done manually, but the environment inside the pipeline is harsh, which poses certain hidden dangers to the safety of the maintenance workers, and even some places where the workers cannot enter

Embodiment Construction

[0029] The application will be further described below in conjunction with the accompanying drawings.

[0030] Such as figure 1 , a cable damage detection device based on laser slam and vision, characterized in that it includes: an acquisition module, a carrier, a CPU module, an image acquisition module, an industrial computer, and a PC terminal,

[0031] Wherein, the acquisition module is used to collect the temperature in the cable duct, the magnetic field and the distance data traveled by the acquisition module. Specifically, sensors such as Hall sensors and laser radars can be used for data acquisition; the carrier is connected to the acquisition module , for loading the acquisition module and moving in the cable duct, the preferred carrier can use a crawler robot; the CPU module is electrically connected with the carrier and the acquisition module, used to collect the data of the acquisition module and Control described carrier to move, preferably, can use STM32 series s...

Abstract

The invention aims to provide a cable damage detection method and device based on laser slab and vision. The method is characterized by comprising the steps of navigating and mapping the interior of acable pipeline through a Cartogrammer package, recording the temperature, magnetic field information and image information of a cable, and detecting a damaged point of the cable; accurately positioning the damaged point through a YoloV3 LA algorithm, and recording information in the form of a coordinate vector and a picture; and recording data in the maintenance process in a local hard disk, andfurther conducting information extraction after maintenance is completed. Due to the introduction of the Yolo v3 LA algorithm, compared with an existing rescue robot, the method and device are low inmanufacturing cost and high in technical implementation feasibility, and in the use process, an operator can remotely control the device to conduct overhaul patrol and obtain real-time data, and doesnot need to enter a pipeline by himself / herself.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to a cable damage detection method and device based on laser slam and vision. Background technique [0002] With the continuous expansion of the coverage of urban cable ducts, in order to ensure the reliability of urban power supply, the level of inspection and maintenance of cable ducts needs to be continuously improved. [0003] For the faults in the cable duct, it is mainly caused by various sundries accumulated in the duct. In order to solve the inconvenience of cable line maintenance and eliminate the existing safety hazards, there are mainly two methods in reality: the periscope method and the robot method. For the periscope method, the long rod with the probe on the top is penetrated into the cable duct. Although this device is simple, the operation is inflexible and consumes a lot of manpower and material resources. In comparison, the robot method is easy to operate and is a ...
