| description | The invention discloses an anti-interference scattered rib automatic labeling method suitable for a three-dimensional design steel bar drawing. The method comprises the following steps of 1, drawing a structure line and a steel bar point line of vector storage on a grid map; 2, calculating a marking line layout area, a marking text ideal layout area and a marking interest area of each group of dispersion ribs; step 3, constructing a labeling line and a labeling text convolution kernel; step 4, calculating an annotation line loss weight map and a local annotation text interferogram; 5, searching and calculating the scattered rib marks in the marked interest area, and if the scattered rib marks meeting the searching requirements exist, drawing; step 6, constructing a global annotation text interferogram based on the annotation text convolution kernel, and constructing a pixel directed connected graph based on the reinforcement graph; and step 7, searching and calculating scattering rib marks in a whole image ra |
