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 the 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, go to step 2, otherwise do not go to the next step; the specific 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 current image and 19 images t...

Abstract

The invention discloses a text detection and recognition method for aided reading of a blind person, and the method comprises the following steps: 1, scene detection: mainly detecting whether an imagephotographed by a camera is a scene where a finger is placed on a reading text or not; 2, finger positioning: achieving fingertip positioning in the step, and taking the fingertip as a cursor for subsequent text detection; 3, text extraction: wherein the text extraction mainly comprises extraction of text lines and extraction operation of words in the text lines; and 4, word tracking: tracking aword box of a correctly identified word by adopting a template matching method. The method is high in operation speed and good in effect, words pointed by the fingertips of the user can be accuratelyrecognized, the cost is low, high universality is achieved, and the method can be widely applied to intelligent 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 aimed at assisting reading for blind people. Background technique [0002] Today, there are 314 million people suffering from eye diseases worldwide. Of these, 269 million have low vision and 45 million are blind. Currently, the visually disabled population in China is 8.77 million, 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 in 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...
