AI Technical Summary
Existing laser monitoring methods are affected by factors such as temperature gradient, humidity and dust during deep foundation pit support in soft soil, resulting in laser spot distortion and making it impossible to accurately obtain the center point of the laser spot, thus affecting the accuracy of horizontal displacement monitoring.
An adaptive weighting strategy is adopted to fit the light spot contour by the maximum inscribed circle and the minimum circumscribed circle, quantify the light spot circularity index, and combine it with the Hough circle detection algorithm to dynamically adjust the pixel weights, suppress the influence of environmental interference on the center calculation, and improve the accuracy of the light spot center coordinate calculation.
It significantly improves the accuracy of spot center coordinate calculation and algorithm robustness in complex environments, ensuring the accuracy of horizontal displacement monitoring.
