Generation method and device of target detection box, storage medium and electronic equipment

The embodiment of the invention discloses a target detection box generation method and device, a storage medium and electronic equipment, and the method comprises the steps: carrying out the object detection of a to-be-processed image, and obtaining a first candidate box and the confidence coefficient of the first candidate box; when the number of the first candidate frames is greater than a first preset number, determining a reference detection frame based on the confidence degree corresponding to each first candidate frame; acquiring a perimeter intersection-union ratio between each second candidate frame in the at least one second candidate frame and the reference detection frame; obtaining at least one third candidate frame based on a size relationship between a perimeter intersection-union ratio corresponding to each second candidate frame and a first preset threshold value; and when the at least one third candidate frame meets the first preset condition, determining the at least one third candidate fram
