Biological characteristic collection method, characteristic collection device and computer readable storage medium

Abstract

The embodiment of the invention provides a biological characteristic collection method, characteristic collection device and a computer readable storage medium. The biological characteristic collection method is applied to the characteristic collection device and the characteristic collection device comprises an image sensing unit and a plurality of light sources. The biological characteristic collection method comprises the steps that when biological characteristics are detected, conducting image collection on the biological characteristics for multiple times through an image sensing unit toobtain a plurality of collected images, and turning light sources at a plurality of different positions on each time of image collection; and processing the plurality of acquired images to obtain biological characteristic images corresponding to the biological characteristics. According to the invention, high-efficiency collection of biological characteristics can be realized.

Description

technical field [0001] The present application relates to the technical field of biometric feature collection, and in particular, to a biometric feature collection method, a feature collection device, and a computer-readable storage medium. Background technique [0002] When the existing feature acquisition equipment collects biometric features such as fingerprints, in order to avoid overlapping of the collected biometric images, when keeping fingers still for multiple acquisitions, or each acquisition only lights up such as figure 1 a light source as shown; or each acquisition lights up as figure 2 Multiple light sources shown, but in the above two ways, the distance c between adjacent light sources that are turned on must be greater than the threshold c 0 , can be as image 3 Shown so that the acquired feature images do not overlap. However, the range of fingerprints collected by the above two collection methods is too small, so that multiple feature images must be col...

Problems solved by technology

However, the range of fingerprints collected by the above two collection methods is too small, so that it is necessary to collect multiple feature images to form an effective biometric image, resulting in low biometric collection efficiency.
