The invention discloses a blasting semi-porosity detection method, device, electronic equipment and storage medium. The method includes: generating the spatial coordinates of any point after the tunnel blasting excavation according to the point cloud model after the tunnel blasting excavation; The spatial coordinates of a point, calculate the maximum value of the principal curvature of any point; cluster the point set formed by the maximum value of the principal curvature to obtain the point class set; calculate the blast hole corresponding to each class according to the point distance in the point class set Length; the half-porosity is calculated according to the blasthole length corresponding to each category and the total design length of the blasthole. The method of the present invention, by calculating the maximum value of the principal curvature of any point in the point cloud model, can automatically identify possible blast hole traces, and does not need to be fitted according to the drilling design parameters, avoiding errors caused by actual drilling lofting and The identification error of the blast hole marks caused by the angular deviation and bending of the drilling axis can overcome the defects of low measurement accuracy, large error and low degree of automation in the prior art.
Description
technical field [0001] The invention relates to the technical field of tunnel engineering construction, in particular to a blasting semi-porosity detection method, device, electronic equipment and storage medium. Background technique [0002] In tunnel engineering construction, blasting plays a very important role in the excavation of key parts, among which half porosity is an important index to evaluate blasting effect. The semi-porosity is also called the blast hole trace rate, which is the percentage of the total length of the blast hole traces on the excavation wall to the blast hole length. In terms of calculating the half-hole ratio, the traditional method is to manually visually observe and record the number of remaining blast holes and measure the length of each complete half-hole with a manual tape measure, and then manually add the lengths of all half-holes to obtain the total number of holes on the excavation wall The total length of the blast hole marks, and the...
