Abstract

The invention relates to the technical field of optical fingerprints, in particular to a method for automatically searching thickness parameters of a display screen, a storage medium and electronic equipment. The method for automatically searching the thickness parameter of the display screen comprises the steps that a fingerprint image is processed, a round dark area corresponding to any point light source is determined, the diameter of the round dark area is D, and the thickness parameter of the screen is calculated according to the value of D. Information of lensless imaging is effectivelyutilized, screen thickness parameters are calculated in real time, and subsequent data processing is facilitated.

Description

technical field [0001] The invention relates to the technical field of optical fingerprints, in particular to a method for automatically searching thickness parameters of a display screen, a storage medium and electronic equipment. Background technique [0002] With the development of information technology, biometric identification technology is playing an increasingly important role in ensuring information security. Among them, fingerprint identification has become one of the key technical means for identification and device unlocking widely used in the mobile Internet field. Under the trend of increasing screen-to-body ratio of devices, traditional capacitive fingerprint recognition can no longer meet the demand, while ultrasonic fingerprint recognition has problems in terms of technology maturity and cost. Optical fingerprint recognition is expected to become an under-screen fingerprint Identify mainstream technical solutions. [0003] Existing optical fingerprint recog...
