Method for positioning position of reinforcing mesh
The invention relates to a method for positioning the position of a reinforcing mesh. The method comprises the following steps: S1, judging the position of a single reinforcing bar: emitting line laser to the direction of the single reinforcing bar, and judging the relative position of the reinforcing bar in a single direction due to the height difference between the single reinforcing bar and a background platform in camera imaging after the line laser is reflected; S2, determining coordinates of a plurality of reinforcing steel bars: emitting a plurality of line lasers to the reinforcing steel bar net to form an array, defining coordinates of a cross point of the line lasers as reference origin coordinates, and obtaining cross points of a single reinforcing steel bar and the line lasersand/or relative position coordinates of the cross points among the reinforcing steel bars through imaging positioning calculation in a visual camera; S3, determining the relative height of the plurality of steel bars: calculating the height difference of the corresponding steel bars relative to the background platform by judging the position difference of the laser breakpoints on the same line. The 2D camera is combined with the line laser, and the reflection condition of each part of the laser in the picture is analyzed through photographing of the camera, so that the accurate relative position of the reinforcing steel bar can be judged.
本发明涉及本发明提供一种定位钢筋网位置的方法，包括以下步骤：S1.单条钢筋位置判断：向单条钢筋方向发射线激光，线激光反射后在相机成像中单条钢筋和背景平台存在高度落差，进而判断钢筋在单方向上的相对位置；S2.多条钢筋坐标确定：向钢筋网发射多条线激光形成阵列，将线激光的一交叉点坐标定义为基准原点坐标，通过在视觉相机里的成像定位计算得到单根钢筋与线激光的交叉点，和/或钢筋间交叉点的相对位置坐标；S3.多条钢筋相对高度确定：通过判断同一线激光断点位置落差，计算出对应钢筋相对背景平台的高度落差。采用2D相机与线激光相结合，通过相机拍照，分析图片中激光各部位的反光状况，可以判断出钢筋准确的相对位置。
