Picture verification code generation method and device, computer equipment and storage medium

The invention provides a picture verification code generation method and device, computer equipment and a computer readable storage medium. The picture verification code generation method comprises the following steps: segmenting a background picture into a plurality of small grids; a non-repeated character is arranged in each small grid; randomly selecting several characters from all the characters as a verification code character group; setting verification icons in small grids corresponding to characters of the verification code character group; and generating a verification page which displays the verification icon and requires to input characters according to the verification icon. According to the picture verification code generation method, decoding can be carried out only by finding out the characters corresponding to the verification icons, a user can identify the verification icons easily, and the manual identification rate is high. Due to various characters and verification icons which can be selec
