The invention discloses an intelligent access control method based on high-definition face recognition. The method comprises the following steps: detecting at least one key point in a to-be-recognizedface image through a face recognition device; extracting a feature of each key point in the at least one key point; matching a target key point in each face template corresponding to each key point according to the feature of each key point; recognizing the face image to be recognized according to the feature of the at least one key point and the feature of the at least one target key point matched from each face template. According to the invention, the to-be-recognized face image can be accurately recognized through the face recognition device, when the resolution of the to-be-recognized face image is small, the face can be quickly and accurately aligned and the face key points can be detected, and the method is high in definition and high in recognition rate.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to an intelligent access control method and device based on high-definition face recognition. Background technique [0002] Face recognition technology is a kind of biometric recognition technology. Face recognition first collects the face image and detects the face area, and then compares the detected face image with the pre-stored face template image, so as to recognize the detected face image as the face image to be recognized to identify. However, when the resolution of the face image to be recognized is low, the position and quantity of the detected feature points are unstable, and the detected feature points are few, so the recognition accuracy is low and the definition is not high. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides an intelligent access control method and device based on hig...
