Problems solved by technology

[0004] In view of this, the main purpose of the present invention is to provide a code recognition method, which is suitable for most of the existing head-mounted augmented reality devices. When the user wears the device and multiple codes appear in the field of view, the The multiple codes are identified, and the target codes are identified and displayed according to the user's choice, which solves the defect that the existing head-mounted augmented reality device cannot accurately and quickly identify the target code when multiple codes appear in the scanning area. user-friendly

Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0048] Such as figure 1 Shown is a flow chart of an encoding recognition method according to an embodiment of the present invention, and the method shown in the figure includes the following steps:

[0049] S1: Collect multiple codes that exist simultaneously in the field of view;

[0050] S2: respectively identify each code and display the corresponding identification information;

[0051] S3: Receive the identification information selected by the user with a vo...

Abstract

The invention provides a code recognition method, which is applied to a head-mounted augmented reality device and comprises the following steps of: A, acquiring a plurality of codes existing in a visual field at the same time; b, identifying each code and displaying corresponding recognition information; c, receiving the recognition information selected by the user through a voice instruction, andrecognizing a target code corresponding to the recognition information; and D, identifying and displaying the content corresponding to the target code. The method is suitable for most existing head-mounted augmented reality devices. When a user wears the device and a plurality of codes appear in a visual field, the plurality of codes can be identified according to user requirements, and target codes are identified and displayed according to user selection, so that the defect that an existing augmented reality device randomly identifies batch codes appearing in a scanning area is overcome, andconvenience is brought to use of the user.

Description

technical field [0001] The invention relates to the field of display systems, in particular to a code recognition method and a head-mounted augmented reality device. Background technique [0002] At present, QR Code (QR full name Quick Response) is a very popular coding method on mobile devices in recent years. It can store more information than the traditional Bar Code bar code, and can also express more Data type, widely used. [0003] At present, most of the scanning code recognition technologies adopted by head-mounted augmented reality devices on the market can only realize the recognition of a single code, and the scene where multiple codes exist at the same time is very common in the industry. When multiple barcodes and QR codes appear in the area at the same time, the identification method is often to randomly identify a certain code, or to identify the largest or clearest code first, and it is impossible to accurately find and identify the target code according to ...
