Problems solved by technology

The traditional method is that workers consult the information of the elements to be measured in paper or electronic process manuals, such as dimensional accuracy, shape accuracy, position accuracy, etc., and then select appropriate tools and methods for the properties of the corresponding dimensions. Due to the variety of elements to be measured , workers need to constantly consult the process manual, which is inefficient and prone to missed and wrong detections. For some measurement elements that cannot be directly measured, it depends on the workers' personal experience
[0004] The detection method of machine vision needs to arrange the camera pose in advance according to the model of the part to be measured. Different parts require different camera configurations, which is not suitable for customized parts such as single piece and small batch; it has high environmental requirements, and for mechanical parts lacking texture , the accuracy of the machine vision method will also be affected, and the layout of the camera will increase the additional cost of land occupation

Abstract

The invention discloses a mechanical part machining precision detection guiding system based on augmented reality. The guiding system comprises guiding information editing and guiding measurement, theguide information editing comprises an AR detection guide process editing module and a visual preform library, the guide measurement comprises an identification positioning module, an interaction module and a visualization module, and the system workflow comprises the following steps: 1, establishing a process manual in an XML form; 2, establishing a visual model prefabricated body; 3, extractingentries corresponding to the XML of the process manual; 4, acquiring the current pose of the part to be measured; 5, guiding a user to measure the measurement elements in the current step by using aproper tool; 6, judging whether the process requirements are met or not by the user according to the measurement result of the user. According to the invention, the problems of low efficiency and highpossibility of missing detection and wrong detection caused by frequent query of paper or electronic process manuals by workers during detection of mechanical parts at present are solved.

Description

【Technical field】 [0001] The invention relates to the field of machining accuracy detection of mechanical parts, in particular to a detection and guidance system for machining accuracy of mechanical parts based on augmented reality. 【Background technique】 [0002] Augmented reality, referred to as AR, is a technology that calculates the position and angle of the camera image in real time and adds the corresponding image. The goal of this technology is to put the virtual world on the screen and interact with the real world. [0003] In the process of mechanical production, it is necessary to measure and detect the various measurement elements required by the part process to ensure the processing accuracy of the part. The traditional method is that workers consult the information of the elements to be measured in paper or electronic process manuals, such as dimensional accuracy, shape accuracy, position accuracy, etc., and then select appropriate tools and methods for the prop...
