Problems solved by technology

But the problem with this method is: from a technical perspective, it is necessary to adjust the focus of AF (Automatic Focus) in place to ensure that it can be clearly aligned during autofocus. The number of steps is related to the step length, and it may be impossible to focus clearly in an instant, resulting in failure to recognize the QR code, thereby affecting the recognition efficiency

Embodiment Construction

[0029] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0030] In this embodiment, the payment device is a product for payment identification, such as some payment tablets (you can refer to the payment tablet installed by the merchant at the checkout counter), an automatic settlement device that can perform scan code payment and face payment (for example, set up in a supermarket) Customer self-settlement equipment), etc., are not limited here. In this embodiment, a payment device with a payment recognition range of 10-120 cm will be taken as an example for illustration, but it should not be regarded as a limitation of the present application.

[0031] see figure 1 , figure 1 It is a schematic diagram of a payment device 100 provided in the embodiment of this application.

[0032] In this embodiment, the payment device 100 may include a depth imaging m...

Abstract

The invention provides a focusing method and payment equipment, and the method comprises the steps: determining a corresponding payment mode according to a current payment scene; when the payment modeis a code scanning payment mode, adjusting the color camera mechanism to a first preset focal length in a fixed-focus mode, so that the payment device identifies the payment code in a first identification range, and the color camera mechanism in the first preset focal length can clearly acquire a payment code image in the first identification range; when the payment mode is a face payment mode, adjusting the color camera mechanism to a second preset focal length in a fixed-focus mode, so that the payment device recognizes a face in a second recognition range, and the color camera mechanism inthe second preset focal length can clearly acquire a face image in the second recognition range. Therefore, efficient payment code recognition can be performed, the recognition success rate is improved, and the payment efficiency is further improved. In addition, the focusing precision requirement of a manufacturer on the color camera shooting mechanism can be reduced.

Description

technical field [0001] The present application relates to the field of optical technology, in particular, to a focusing method and a payment device. Background technique [0002] With the explosion of face payment and scan code payment, many manufacturers have begun to develop and produce products for face payment and scan code payment, such as Alipay, WeChat face payment and scan code payment. How to improve the efficiency of face payment and scan code payment has become one of the research directions of many manufacturers. For example, a payment recognition product is required to meet both short-range scan code recognition and long-distance face recognition. However, the system quickly acquires clear images (such as payment code images, face images, etc.) is one of the prerequisites for efficient payment. [0003] For example, for face payment products with 3D (3-Dimension, three-dimensional) structured light modules, the working distance is generally 30cm-120cm. Because...
