An automatic catheter recognition method based on vision detection

Abstract

The invention provides a guide pipe automatic identification method based on visual detection. The method includes the following steps that detection geometric data of real guide pipes are obtained by means of a multi-view visual detection instrument; geometric analysis is carried out on a guide pipe three-dimensional theoretical model in a guide pipe sample piece library to obtain pipe shape geometric data of guide pipes; the pipe shape geometric data of guide pipe models are traversed and matched with the detection geometric data of the real guide pipes, and matched targets are automatically obtained according to allowance parameters; identification information of the guide pipe models in the guide pipe sample piece library corresponding to the real guide pipes is determined and pasted to the real guide pipes to complete identification of the real guide pipes. According to the method, operation workers on a work site can directly obtain management information of parts of the real guide pipes according to a multi-view visual detection result, bar codes are generated and attached to parts of real pipelines, and the identification difficulty of the parts of the real pipelines is greatly lowered.

Description

technical field [0001] The invention relates to a method for automatic recognition of catheters based on visual detection, which belongs to the technical field of mechanical engineering. Background technique [0002] The pipeline system is an important part of the spacecraft propulsion system, thermal control system, and environmental control and life protection system. The storage tanks, valves, thrusters and other components of each system are connected by pipelines to form a highly airtight environment to realize the main functions of the system. The performance of the pipeline of the spacecraft will directly affect the function, reliability and life of the spacecraft. [0003] The pipeline system of a spacecraft is generally composed of conduits and pipeline connectors. The conduits must obey the layout of the components, equipment and instruments in the spacecraft, pass through the gaps between components and equipment, and meet the spatial position requirements for wel...
