摘要： A method for generating a palmprint sample includes: generating positioning point data according to a palmprint principal line distribution rule, the positioning point data comprising first data corresponding to a first principal line positioning point and second data corresponding to a second principal line positioning point; generating adjusting point data according to a palmprint principal line curving rule, a principal line adjusting point corresponding to the adjusting point data being configured to control a curving parameter of a principal line formed by the first principal line positioning point and the second principal line positioning point; generating a palmprint principal line based on the first data, the second data and the adjusting point data; and generating at least one palmprint sample comprising the palmprint principal line.
