Open caisson flatness detection method based on three-dimensional laser scanning
The invention discloses an open caisson flatness detection method based on three-dimensional laser scanning. The open caisson flatness detection method based on three-dimensional laser scanning comprises the following steps: scanning a target area of an open caisson to be detected to obtain point cloud data; preprocessing the point cloud data; performing triangulation network construction on the preprocessed point cloud data; performing model slicing on the plane of the key area of the open caisson to be detected; respectively connecting slice graphs obtained by slicing end to end to obtain a straight line, and respectively calculating the distance between the slice graphs and the straight line at the key part of the open caisson to be detected; and the result obtained in the step 6 is counted, and a flatness exaggerated display graph is drawn. According to the open caisson flatness detection method based on the three-dimensional laser scanning, the open caisson flatness detection method based on the three-dimensional laser scanning is convenient to implement, and the flatness value of any position in the open caisson interval to be detected can be simply, efficiently and accurately calculated.
