Embodiment
[0038] The laser scanner is installed on the crane or above the material to be measured. Due to the generally used point laser scanning, the scanning process is as follows: figure 2 As shown: In the set scanning interval, the laser scans from point A to point B, and then returns to scan point B1 from A1, and so on until the entire set interval is completed.
[0039] Due to the continuous update of scanning information, the scanned data is read in socket form in real time, and then stored in the database.
[0040] When the entire scan is completed, the database will store the 3D bitmap of the entire scanning area, and this bitmap data records the angle of the entire pan / tilt and the angle of the laser, which have been measured and recorded.
[0041] The database program sorts the three-dimensional data of the scanned data according to certain rules, and deletes some data beyond the normal range, and filters and inserts two adjacent normal data.
[0042] Since the scanning res...
