Abstract

The invention provides an information acquisition method and a terminal. The terminal comprises a light emission unit and a flight time sensor. The method comprises the following steps: controlling the light emitting unit to emit a light signal, and controlling the time-of-flight sensor to detect the light energy of the light signal reflected by the detected object; And generating biological characteristic information corresponding to the detected object according to the light energy detected by the time-of-flight sensor. Visibly, the biological characteristic information is obtained based onthe time-of-flight distance measurement; the requirement for the cleanliness of the detected object can be lowered, so that under the condition that the cleanliness of the detected object is poor,; compared with the prior art, the matching degree of the generated biological characteristic information and the detected object is high, the recognition speed can be increased when recognition is carried out through the biological characteristic information, and the recognition passing rate is increased.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to an information acquisition method and a terminal. Background technique [0002] With the rapid development of communication technology, the functions of terminals are becoming more and more abundant, and the issue of privacy has become an issue that people are more and more concerned about. In order to better improve security and protect privacy, recognition technologies such as fingerprint recognition and face recognition are more and more widely used in terminals. [0003] However, the existing recognition technology has the disadvantage of low matching degree between the generated biometric information and the measured object due to the poor cleanliness of the measured object, which in turn leads to a low recognition pass rate. Contents of the invention [0004] Embodiments of the present invention provide an information acquisition m...
