Problems solved by technology

Although some companies have introduced robotic automated 3D scanning technology without marker point splicing, the response from the market is not good. The main reason is that the positioning accuracy of the robot is not high, so this kind of product can only be used in occasions where the accuracy is not high. It can not meet the current demand for a large number of high-precision detection
[0005] Under the current status of the development of robots, relying solely on the positioning accuracy of robots for 3D scanning stitching cannot meet the needs of high-precision detection in the industry. In the original non-automated products, the layout and pasting positions of the marker points depend entirely on the technical engineers. Based on experience, the subjectivity is relatively strong, and the optimal efficiency and results cannot be achieved. With the development of robot automated 3D scanning technology, the layout position of the marker points has been calculated and generated by the software algorithm. According to the model of the scanned object, the software algorithm It can automatically generate how many marker points need to be pasted, and where each marker point should be pasted on the object, but the current technical level can only give the layout position of the marker points on the digital model, but cannot give effective instructions The method allows engineers to accurately paste the marker points to the positions calculated by the software, resulting in large or small errors between the positions pasted by different engineers and the ideal calculated positions. The experience in practical applications is very bad. If the marker points are pasted The position of the location is not accurate enough, which often causes the virtual planning to be unable to be completed in the actual path scanning, and it is necessary to re-fill the marker points and re-plan, which adds a lot of trouble to the application of automation technology

Abstract

The invention provides a pasting indication method for a mark point orienting to three-dimensional scanning and based on on-line image processing. After a virtual layout position of the mark point required for the three-dimensional scanning is calculated according to digital-analog information of a measured object and parameter information of a three-dimensional scanner, it is judged by an onlineimage technology whether a current coordinate position is pasted with the mark point, passing processing is performed on the pasted mark point, a warning treatment is utilized by a coordinate positionof an unpasted mark point to guide a technical engineer to perform pasting work of the mark point in real time, and the fluency of a later three-dimensional scanning process is ensured. The method isbased on a reliable online image processing technology, brings great convenience and accuracy to the pasting work of the mark point in a three-dimensional scanning process, avoids influence of humanobjective factors on a pasting layout of a position of the mark point, and provides great convenient conditions for automation f the three-dimensional scanning and development of process standardization.

Description

technical field [0001] The invention belongs to the fields of monocular structured light three-dimensional scanning, binocular structured light three-dimensional scanning, and binocular laser three-dimensional scanning based on machine vision, and relates to marker point technology, in particular to a layout position of marker points in the process of three-dimensional scanning using online image processing indicated method. [0002] technical background [0003] With the popularization of non-contact 3D scanning technology and the development of industrial inspection requirements, the demand for 3D scanning products is increasing year by year, and the market demand and share of automated 3D scanning products that combine 3D scanners with robot automation technology is even greater. It is showing a blowout trend, but the current scanning products still cannot get rid of the shackles of the marker points, and need to rely on the marker points of the public parts for multiple s...
