Steel bar view single-point bar automatic labeling method

The invention provides a steel bar view single-point bar automatic labeling method. The method comprises the steps that S1, a steel bar sectioning view is converted into a grid steel bar map; s2, traversing all single-point reinforcements in the grid reinforcement map, and calculating candidate offset vectors of the annotation text of the current single-point reinforcements; s3, constructing an annotated text convolution kernel, and calculating an annotated text offset azimuth loss graph and an annotated text offset azimuth graph in the annotated interest area range of the current single-point rib; s4, calculating an annotation lead interference pattern, an annotation lead direction loss pattern and an annotation lead length loss pattern in the current annotation region of interest range; and S5, calculating an annotated layout loss graph, retrieving an annotated layout orientation corresponding to a minimum loss value in the annotated layout loss graph, and annotating the current single-point rib according t
