Embodiment Construction

[0089] Below in conjunction with accompanying drawing description, the present invention will be further described:

[0090] This embodiment is aimed at the specific application of aided reading for the blind. The detection and recognition of text in the captured image is carried out according to the following steps. The overall implementation process is as follows: figure 1 shown. It can be seen from the figure that the detailed implementation process mainly includes the following main steps:

[0091] Step 1: Determine whether the scene in the current image is a finger placed on the reading text through scene detection, if so, proceed to step 2, otherwise do not proceed to the subsequent steps; the specific processing process of this step is as follows:

[0092] Step 11. Pre-shoot some typical images containing the user's fingers and the text area where they are located through the camera, and save them in the database. See figure 2 (a);

[0093] Step 12, taking the curre...

Abstract

The invention discloses a text detection and recognition method aimed at assisting reading for blind people. The method includes the following steps: Step 1: Scene detection, which mainly detects whether the image captured by the camera is a scene where fingers are placed on the reading text; Step 2 : Finger positioning, this step realizes the positioning of the fingertip, and uses the fingertip as a cursor for subsequent text detection; Step 3: Text extraction, this step mainly includes the extraction of text lines and the extraction operations of each word in the text line; step 4: Word tracking, this step mainly uses the template matching method to track the word box of the correctly recognized word. The method of the present invention has fast running speed and good effect, not only can accurately identify the word pointed by the user's fingertip, but also has low cost and strong versatility, and can be widely used in smart products such as wearable auxiliary reading rings for the blind .

Description

technical field [0001] The invention belongs to the application field of computer vision, and in particular relates to a text detection and recognition method aiming at auxiliary reading for blind people. Background technique [0002] Today, there are 314 million people suffering from eye diseases worldwide. Of these, 269 million had low vision and 45 million were blind. Currently, there are 8.77 million visually disabled people in China, accounting for about 19.5% of the total number of blind people in the world and about 0.7% of my country's total population. According to the analysis of relevant authoritative organizations, six years later, the number of blind people in our country will exceed 75 million. Therefore, how to help blind people overcome the difficulties of daily study and life, especially the most basic reading problems, has great research value and social significance, and also has broad application prospects. [0003] At present, there are many auxiliary...
