The invention provides an OCR recognition result confidence determination method and a device, and electronic equipment, and the method comprises the steps: inputting a to-be-recognized image into a pre-trained convolutional neural network, and obtaining a plurality of groups of output results; judging whether the number of effective character recognition results in a plurality of character recognition results included in the plurality of groups of output results is greater than a preset number; if the number of the effective character recognition results is smaller than the preset number, determining 0 as the confidence coefficient of the OCR recognition result; if the number of the effective character recognition results is greater than the preset number, obtaining a probability value corresponding to each character in the effective character recognition results by normalizing the effective logistic regression matrix; and determining the minimum probability value in the obtained probability values as the confidence coefficient of the OCR identification result. Visibly, through the method of the invention, the confidence coefficient of the OCR recognition result is obtained whilethe OCR recognition result is obtained, so that the reliability degree of the OCR recognition result can be evaluated through the confidence coefficient of the OCR recognition result.
