Summary:The invention provides an automatic correction method for a file picture, electronic equipment and a storage medium, and the method comprises the steps: determining a boundary inclination angle of each character block through extracting a boundary frame coordinate of each character block in the file picture, and further correcting the boundary inclination angle of each character block according to the boundary inclination angle of each character block; determining the up-down and left-right average inclination angle of the file picture; determining a character area of the file picture according to the up-down and left-right average inclination angle of the file picture and the highest point coordinates, the lowest point coordinates, the leftmost point coordinates and the rightmost point coordinates of all the character blocks; according to the scheme, the character area of the file picture can be accurately extracted, a large amount of training cost is not needed, OCR recognition is carried out on the correct
