摘要: A biometric animal identification system includes a set of jaws including: a first jaw; and a second jaw cooperating with the first jaw to close over and to flatten a portion of an ear of an animal. The system also includes: an optical emitter arranged on the first jaw and configured to emit light toward the second jaw to illuminate the portion of the ear inserted between the first jaw and the second jaw; a camera coupled to the second jaw and defining a field of view intersecting the optical emitter; and a sensor coupled to the set of jaws and configured to output a signal representing closure of the set of jaws over the portion of the ear. The system also includes a controller configured to trigger the camera to capture an image of the portion of the ear, illuminated by the optical emitter, based on the signal.

摘要: A camera device is provided. The camera device includes a light emitting portion configured to change a light path of light according to a first control signal and output the light along a first light path or a second light path, a light receiving portion configured to receive the light reflected by an object and generate an electrical signal, and a control portion configured to generate the first control signal which controls the light path of the light to be changed to the first light path or the second light path. Here, the light emitting portion outputs the light with a first pattern along the first light path or outputs the light with a second pattern along the second light path.

摘要: An imaging device and an authentication controller are provided. The imaging device includes a modulator that includes a first pattern and that modulates light intensity with the first pattern, an image sensor that converts a light beam transmitted through the modulator into imaging data and outputs the imaging data, an image processing unit that performs, to the imaging data, a reconstruction process in which an image of the subject is reconstructed based on the cross-correlation operation between the imaging data and the pattern data having a second pattern and acquires an image, and a distance measurement unit that repeats the reconstruction process to the imaging data while changing a focus distance and acquires a focus distance having a highest contrast in a measurement region as a distance. The authentication controller performs image authentication and distance authentication using image data and distance data acquired by the imaging device.

摘要: The present disclosure relates to several types of finger vein sensor. In certain embodiments, the finger vein sensor includes: an image sensor, and an infrared light source. Image sensor captures infrared image of finger vein pattern of a finger of a target human. The image sensor faces down and is positioned at top of finger vein sensor. The infrared light source may include a predetermined number of infrared light-emitting diodes (LED), and they are arranged in one or more rows and one or more columns and positioned at bottom of finger vein sensor. The finger is positioned between infrared light source and image sensor. The infrared light from the infrared light source irradiates the finger vertically from the bottom to generate the infrared image of finger vein pattern of the finger on the image sensor, and the image sensor captures the infrared image of finger vein pattern of the finger.

摘要: Provided is a recognition method of 3D vein pattern including the following steps. A plurality of first light beams are emitted by a recognition device to a wrist of a user. A plurality of first reflected light beams from the wrist are received by the recognition device to form a first 3D vein pattern of the wrist. Differences between the first 3D vein pattern and a wrist vein pattern of a database are compared to identify an identity or a gesture of the user. A recognition device of 3D vein pattern is also provided.
