Concrete terrace flatness detection method and system and control method

The invention provides a concrete terrace flatness detection method and system and a control method.The detection method comprises the steps that site data of a to-be-detected concrete terrace are scanned through a scanner, then the scanned site data are uploaded to a computer, and the site data are constructed into a point cloud model through the computer; dividing the point cloud model into a plurality of rectangular blocks, exporting a gridding elevation map of each rectangular block, constructing a virtual guiding rule, comparing grid points in the gridding elevation maps through the virtual guiding rule, and finally counting the proportion of qualified grid points so as to judge the flatness of the concrete terrace to be detected. Therefore, the concrete terrace flatness detection work can be efficiently and accurately realized, and the local flatness condition of the concrete terrace can be reflected according to the divided rectangular blocks. 本发明提出了一种混凝土地坪平整度检测方法、系统及控制方法，所述检测方法通过扫描仪扫描待测混凝土地坪的站点数据，然后将扫
