Crane balancing weight detection method and equipment and crane

The invention relates to the field of engineering machinery, and discloses a crane balancing weight detection method and equipment and a crane. The method comprises: collecting an image of the balancing weight, and obtaining one or more foreground target areas by segmenting the image; extracting edge features of the one or more foreground target areas; carrying out feature matching on the extracted edge feature of each foreground target region in the one or more foreground target regions and edge features related to the balancing weight in a pre-established standard model library, and calculating a matching value; and under the condition that the matching value is greater than a threshold value, determining that the corresponding foreground target area corresponds to the balancing weight.According to the crane balancing weight detection method and the crane balancing weight detection equipment provided by the invention, the accurate identification of the balancing weight of the heavymachine can be realized, s
