Adjusting device and method of face recognition equipment

Abstract

The invention provides an adjusting device and method for face recognition equipment, and the method comprises the steps: enabling a camera to be started to carry out the shooting of a face biologicalfeature image of a user after the user is close to the face recognition equipment, and judging whether the face biological feature image is shot or not; if it is judged that the shooting does not exist, based on a plurality of preset definition data items which respectively define the installation base of the camera and correspondingly carry out different dynamic adjustment actions, informing a user of carrying out corresponding dynamic adjustment on the installation base by providing one or more instructions corresponding to the definition data items; and after an instruction provided by a user is received, enabling the mounting base to perform corresponding dynamic adjustment, so that the visual angle range of the camera mounted on the mounting base is adjusted to shoot a recognizable face biological characteristic image of the user. Therefore, under the condition that the user does not need to move forwards, backwards, leftwards and rightwards and / or change the face height, face recognition is rapidly and conveniently achieved, the use experience of the user is improved, and the recognition efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of face recognition, and in particular relates to an adjustment device and method of a face recognition device. [0002] Background technique: [0003] Face recognition (face recognition) is a widely used biometric technology at present. Compared with other biometric recognition technologies (fingerprint recognition, palm recognition, iris recognition and voice recognition), face recognition has the following advantages: Each of the other biometric identification methods requires the user's cooperation, but face recognition does not require the user's passive cooperation, and can be automatically used in concealed occasions, such as monitoring operations by the public security department; when recording the biometric record of a user who attempts to log in, Only the face can verify the identity of the user more intuitively and conveniently; compared with traditional biometric identification technology, face r...

Problems solved by technology

It can be seen that the scheme of using a fixed face recognition device for face recognition has the following disadvantages: the viewing angle range of the camera installed on the face recognition device is fixed, and it cannot dynamically adjust the camera in the three-dimensional coordinate space. The scenario is that in ordinary supermarkets and retail stores, where the space is small or the queue is long, it is impossible to allow users to move back and forth reasonably or conveniently, so that it is impossible to conveniently realize the face recognition of users by fixed face recognition equipment

[0005] At present, in many usage scenarios, especially in ordinary supermarkets and retail stores, portable face recognition devices are also widely used for facial recognition payment. Portable face recognition devices are also equipped with cameras with a fixed viewing angle range. It is dynamically adjusted in the three-dimensional coordinate space and is usually fixed on the cashier counter. Since these application scenarios usually have relatively narrow spaces and different heights of the cashier counter, users of different heights often have some differences between the height of the cashier counter and the height of the cashier counter. When the matching user stands in front of the cashier, the face cannot enter the viewing angle of the camera on the portable face recognition device, and the user moves back and forth or left and right to adjust the distance from the cashier or adjust the face by squatting or stepping height, will cause a lot of inconvenience, and also lead to a poor user experience of face-swiping payment
