Abstract
A detection system and a detection method are provided. The detection method includes: receiving an image containing a face by an angle acquisition module and obtaining a first angle and a second angle of the face based on the image; obtaining a first projection value and a second projection value based on the first angle and the second angle by a projection calculation module; and performing by a confidence calculation module: performing an exponentiation calculation on the first projection value based on a first correction value to obtain a third value; performing an exponentiation calculation on the second projection value based on a second correction value to obtain a fourth value; and obtaining a confidence value based on the third value and the fourth value.
