Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] According to one embodiment of the present invention, an optical tag is provided. refer to figure 1 And generally speaking, the optical label includes two or more light emitting sources, a control circuit, a power supply, and other optional modules. These modules will be described separately below.

[0046] 1. Light source

[0047] Generally speaking, the light source of the light tag is a light-emitting object. A luminous object is an object that can emit directional light waves (including visible light and invisible light) to the surroundings, and the emitted light has cha...

Abstract

The present invention provides an optical tag and a method and device for identifying the optical tag. The optical tag includes: N light emitting sources, and the change pattern of the light emitted by them within a period of time represents its encoded information. The coded information includes synchronization information and unique identification information, the synchronization information is used to locate the unique identification information, and the unique identification information specifies the thing bound to the optical tag. The optical label provided by the present invention can be quickly identified by a personal device with a camera device at a long distance, and its identification distance is within the user's visible range, which greatly improves the identification distance of existing RFID labels and two-dimensional code labels. In addition, personal devices can recognize light tags in video transmitted over the network.

Description

technical field [0001] The present invention relates to the technical field of signal encoding, in particular to an optical tag, especially an optical tag that can be identified by a personal device with a camera device, and a method and device for identifying the optical tag. Background technique [0002] In the Internet of Things environment, object recognition is the most basic and important application. Usually, people realize object recognition by scanning the labels on the objects. Currently, widely used tags include RFID (Radio Frequency Identification) tags and QR code tags. An RFID tag with a working frequency of 120KHz to 134KHz can be recognized at a furthest distance of about 10 cm; a 5 cm x 5 cm QR code can be recognized at a furthest distance of about 30 cm. In addition, since the two-dimensional code can only be recognized under certain light conditions, in scenes without such light conditions (such as night), it is impossible to recognize the two-dimensional...
