Rice, and the slanted angle detection method of above-mentioned existing lateral wall 3-1-1 is needed on the y-axis direction along lateral wall 3-1-1
Varying cross-section position repeated measurement its corresponding multigroup LBDAnd LADLength value, also need each group length vertical generation respectively
Enter formula 1 to calculate repeatedly, this all causes, and the detection efficiency of above-mentioned old detection method is low, and workload is heavy.Additionally, by operator Jing
The mode for testing the position to judge the vertical subpoint D from A points is also readily incorporated measurement error, affects larger to certainty of measurement.
