Problems solved by technology

[0002] Visible light tags have the characteristics of long recognition distance, and have gradually been widely used. When existing handheld devices recognize visible light tags, when there are multiple light tags in the screen, the recognition may be confused and confused. Phenomenon, resulting in recognition errors or the application can not complete the setting function, so it is necessary to propose a method that can realize the recognition of multiple visible light tags, and will not appear confusion and confusion

Embodiment 1

[0030] figure 1 Among them, 1-1 is a mobile smart device that collects optical tags. During the collection process, mobile smart device 1-1 finds that there are multiple optical tags, and these optical tags are respectively 1-2 to 1-11; mobile smart device 1- 1. Calculate the center position of each light label, and divide the screen into multiple areas according to the center position of each light label. The areas are separated by interval lines to form multiple non-overlapping closed sub-areas; adopt "four-color map According to the division principle of ", change the background color of each sub-area with different colors of adjacent areas; superimpose the prompt information of the light label identified in 1-2 to 1-11 on the corresponding position of the above screen; when the user is on the display area 1 If you are interested in the light tags in -8, click the display area 1-8 with your fingertips; the mobile smart device 1-1 starts to recognize the light tags correspon...

Embodiment 2

[0032] figure 2 Among them, 1-1 is a mobile smart device that collects optical tags. During the collection process, mobile smart device 1-1 finds that there are multiple optical tags. Medicine, entertainment, and service four categories of goods; 1-1 uses the "Z"-shaped curve of 3-1 to traverse and identify each optical tag from 2-2 to 2-11 in turn, and deliver these optical tags to process t in sequence 1 , t 2 , t 3 , t 4 , t 5 , t 6 , t 7 , t 8 , t 9 , t 10 , t 11 Carry out recognition processing and get the recognition result r 1 、r 2 、r 3 、r 4 、r 5 、r 6 、r 7 、r 8 、r 9 、r 10 、r 11 , which are divided into food, medicine, entertainment, and service categories according to the types of the recognition results, and presented to the user in the form of a table.

Abstract

The invention discloses a fast recognition method for multiple optical labels. The method comprises the steps as follows (1) all visible optical labels within a recognition range of a camera are obtained, all visible optical labels are displayed into one display region of a handheld device, the handheld device recognizes regional center positions of the visible optical labels and divides the display region of the handheld device into multiple display regions by employing the regional center positions of the visible optical labels as base points, wherein one visible optical label corresponds to one display region; (2) the display regions are distinguished, realistic pictures of the positions at which the visible optical labels are located are inserted into the display regions corresponding to the visible optical labels, and meanwhile, the visible optical labels are inserted into the corresponding realistic pictures of the positions at which the visible optical labels are located; and (3) a user clicks any display region and the handheld device recognizes visible optical label content corresponding to the display region. According to the method disclosed by the invention, recognition of the multiple visible optical labels can be achieved and the phenomenon of disordered visible optical labels can be avoided.

Description

technical field [0001] The invention belongs to the technical field of optical label identification and relates to a rapid identification method for multiple optical labels. Background technique [0002] Visible light tags have the characteristics of long recognition distance, and have gradually been widely used. When existing handheld devices recognize visible light tags, when there are multiple light tags in the screen, the recognition may be confused and confusing. Phenomena that lead to recognition errors or the failure of the application to complete the setting function. Therefore, it is necessary to propose a method that can realize the recognition of multiple visible light tags without confusion and confusion. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a rapid identification method for multiple optical labels, which can realize the identification of multiple vis...
