Problems solved by technology

Method Calculate the fractal dimension value of the plant outline point cloud data by the Minkowski dimension method, first divide the spatial range of the preprocessed point cloud data into multi-scale cubic boxes, and count the non-empty cubic boxes corresponding to the division scale Then use the logarithmic value of the statistical results to make a log-log coordinate map, and finally obtain the slope of the fitted line through the points in the log-log coordinate map, that is, the fractal dimension value, and use the fractal dimension value of the three-dimensional point cloud contour of the plant to distinguish plant species , high degree of intelligence, efficient and accurate plant identification, overcomes the problem that the existing technology mainly relies on manual identification and classification, requires a lot of manual participation to complete the work, and the professional level of plant classification personnel will have a huge impact on the classification results. It is a new method of plant identification and classification with high value.
