Automatic detection device and detection algorithm for transmission tower foundation
The measurement of foundation openings and tower-pile height differences is predominantly per-formed manually,which is time-consuming and prone to errors.This study presents an automated mea-surement method that combines Euler transformation with laser distance measurement to enhance both ac-curacy and efficiency.The proposed system employs a two-degree-of-freedom turntable,driven by a high-precision motor,and equipped with a single-point laser to scan designated areas along predefined trajecto-ries.An Euler rotation transformation is utilized to establish the measurement model,which is further re-fined by compensating pitch angle errors obtained from horizontal rotation contour experiments using the least squares method.The integration of laser distance measurement,encoder feedback,and attitude sen-sor data enables precise calculations of foundation openings and tower-pile height differences.A prototype device was developed and validated through laboratory comparison tests and field experiments on transmis-sion tower foundations.Results demonstrate that the device is user-friendly and highly accurate,with foun-dation opening measurement errors controlled within±0.2%,tower-pile height difference errors within 5 mm,and experimental group deviations from the average value maintained within±0.15%.This method significantly improves the precision and efficiency of foundation and tower-pile measurements,offering a robust solution for automated detection in practical engineering applications.
