A maintenance visual automatic judgment method and system

Abstract

The invention discloses a visual automatic judgment method and system for maintenance. The method includes: determining the three-dimensional space observation point set and the three-dimensional space observed point set under the current iteration times; connecting each eye point with any maintenance object point to obtain the initial visible line segment set under the current iteration times; deleting the initial In the visible line segment set, the initial visible line segment located outside the visible cone with the human eye as the vertex is obtained at the current iteration number; the initial solution set is intersected with the 3D model of the product in the maintenance scene to obtain the current iteration number. The set of visual solutions; calculate the statistical measure of system complexity under the current iteration number, until the absolute value of the difference between the statistical measure of system complexity under the current iteration number and the statistical measure value of the system complexity under the previous iteration number is less than the set value, so as to determine the visual distribution result of the observed points in the three-dimensional space. The invention can improve judgment efficiency and judgment accuracy.

Description

technical field [0001] The invention relates to the technical field of maintainability, in particular to a visual automatic judgment method and system for maintenance. Background technique [0002] With the development of technology, various products are developing in the direction of high integration, automation and intelligence, and the difficulty of maintenance is increasing. In order to ensure that the products have better reliability and lower life cycle costs, maintainability design and analysis become Essential research throughout the design process. [0003] Maintenance visibility is an important factor in maintainability design and evaluation. Maintenance visibility refers to whether the maintenance personnel can see the maintenance object during operation. It is one of the prerequisites for the product to be repaired, so it needs to be judged. Good visibility design can enable maintenance personnel to find the best operating position and posture. The space positi...

Problems solved by technology

Among them, the physical prototype consumes a lot of time and material resources and has a lag, and the judgment can only be made after the product design is finalized; the simulation through the virtual prototype relies too much on the evaluation of functional modules, and this process is highly subjective and cannot be accurate. Establishing the connection between the person and the object of judgment can easily lead to a large difference between the judgment result and the actual situation, so it is difficult to obtain a quantitative judgment result

Therefore, the existing maintenance visibility judgment method has the disadvantages of long time consumption and poor accuracy
