Triangulation length measurement based on single-line laser Ladar

In view of the time-consuming and laborious shortcomings of traditional measurement of artillery formation, a length measurement method using single-line laser radar is proposed. The working principle of single line laser radar and the length measurement principle of triangle method are analyzed. Using wavelet scattering model to extract jump points at both ends of the measured length, The experimental results show that the proposed method has the advantages of low cost and strong timeliness, and the accuracy can meet the relative error of 1%.
