Automatic calculation method and system for carbon emission curve report image, medium and equipment

The invention discloses an automatic calculation method and system for a carbon emission curve report image, a medium and equipment, and the automatic calculation method comprises the steps: firstly, extracting a curve color value through user clicking, then positioning a curve main body region through a Yolov5s target detection algorithm, and carrying out the cutting, thereby reducing the interference of irrelevant regions. Then, extracting pure lines of the curve by adopting HSV conversion, and extracting legend information by using a text detection and recognition model; finally, through curve edge processing and actual coordinate scaling, the mean value of the curve is obtained through calculation and used for calculating the carbon dioxide concentration. According to the method, full-automatic numerical calculation and information extraction of a carbon emission curve report image are realized through multi-model cooperation, a main body area of a curve graph can be automatically positioned, it is guaran
