Problems solved by technology
For many high-precision industries, simple flatness information is far from enough, and it is impossible to accurately and detailedly understand the accuracy information of products
In the CAD systems that have been released on the market, the algorithm for point cloud processing is not accurate enough, and its functions are simple. It can only provide some basic point cloud information, and can only process some basic graphics. For some complex structures, Irregular graphics cannot be processed

The invention discloses a graphical plane data analysis system and method, and is applied to a computer apparatus. The method comprises the following steps: obtaining a point cloud file from a database, analyzing point cloud data from the point cloud file, and performing triangular grid processing on the point cloud data; according to the point cloud data after the triangular grid processing, fitting a plane, and calculating a normal vector of the fitted plane; calculating a distance from each triangle after the triangular grid processing to the fitted plane; calculating a normal vector of each triangle; determining whether the included angle between each triangular normal vector and the normal vector of the fitted plane is smaller than 90 degrees; marking all the triangles with the included angles smaller than 90 degrees with different colors so as to represent different point cloud precision; and generating a color point cloud distribution image report indicating the point cloud precision and generating a point cloud information report indicating point cloud correlation information and precision. By implementing the system and method provided by the invention, a high-precision point cloud precision analysis report can be generated through analyzing and processing the point cloud data.
Description
technical field [0001] The invention relates to a graphic data processing system and method, in particular to a high-precision graphic plane data analysis system and method. Background technique [0002] The problem of precision has always been one of the core issues in the processing and manufacturing industry. The precision of products is related to core elements such as product quality and safety. After the product is processed, it is difficult to have a detailed understanding of the product accuracy. Even if the product is scanned, only point cloud data is obtained, which is not conducive to data analysis, and the information obtained is less, not intuitive, and difficult to understand. In many CAD systems, there is no special system to analyze the accuracy of the point cloud, and many systems only perform the most basic processing on the point cloud to calculate the flatness information. For many high-precision industries, simple flatness information is far from enough...
