近年来,激光在线检测系统越来越多地运用到白车身的生产过程中。普通的检具测量、三坐标测量只能进行离线小样本抽检,激光在线检测可以实现对关键部位在线100%全检。着重分析地面/工位坐标系基准条件下,小数据量分析与大数据量分析及筛选/排序条件不同(时间别/台车别)时所带来的图示结果差异,提出了数据应用的一种分析方法。
In recent years, laser on-line inspection system is increasingly used in the production process of the white body. Ordinary gage measurement, coordinate measurement can only be off-line sampling of small samples, online laser detection can be achieved on the key parts of the 100% full inspection. Focus on the analysis of ground / station coordinate system under the baseline conditions, small data volume analysis and analysis of large amounts of data and screening / sorting conditions (time / car do not) bring the difference between the graphical results, the application of the data A method of analysis.
