The invention discloses a palm image acquisition device. The palm image acquisition device comprises a ranging component, an infrared camera shooting component and a controller, wherein the ranging component is used for measuring the acquisition distance between the palm of a user and the infrared camera shooting module, the infrared camera shooting component comprises a plurality of infrared cameras which have different shooting angles and are used for shooting palm images of the user at different acquisition distances, the controller is electrically connected with the ranging component and the infrared camera shooting component, and used for selecting the corresponding infrared camera to shoot according to the acquisition distance. The palm image acquisition device disclosed by the invention is wide in acquisition region. The invention further discloses a palm image acquisition method.
Description
technical field [0001] The present invention relates to the technical field of identity recognition equipment, in particular to a palm image acquisition device and a palm image acquisition method. Background technique [0002] With the development of science and technology, more and more identification devices have been widely used in the market, such as attendance machines, access locks, etc. With the rapid development of biometric identification systems, there are more and more types of identification devices, and more and more people need to collect and identify biometric features. Due to the hygiene problems of some collectors, contactless collectors are now very popular. However, since the existing non-contact collectors have strict requirements on the distance between the object to be collected and the image collector, the object to be collected is likely to be too short or too far away from the image collector, resulting in Outside the collection area, the collectio...
