Embodiment Construction

[0038] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and examples, but the implementation and protection of the present invention are not limited thereto.

[0039] Such as figure 1 As shown, a method for automatically identifying and reading drug instructions in this example uses a recognition system with a camera, a processor, and a voice playback module, including the following steps:

[0040] (1) To identify the instruction manual, the system automatically recognizes the characters of Guoyao Zhun by taking a picture of the drug instruction sheet and obtains specific drug information by calling the Internet interface;

[0041] (2) Correction of rotated text, through the Hough line detection algorithm to realize the correction of rotated text based on Fourier transform, and rotate the text with rotation deviation obtained by shooting to the horizontal;

[0042] (3) Paper overturn detection, ...

Abstract

The invention discloses a method for automatically identifying and reading a medicine specification. The method comprises the following steps that a system takes a picture of one medicine specification, automatically identifies the SFDA (State Food and Drug Administration) approval number, and acquires the specific medicine information by calling an internet interface; the rotating text correction based on the Fourier transform is carried out through the Hoff straight line detection algorithm, and the shot text with rotation deviation is rotated to be horizontal; whether paper is overturned or not is detected by identifying that whether characters exist on the medicine specification or not, and the overturned paper is overturned through voice prompt; the picture after rotating text correction and the picture obtained after overturning for 180 degrees are simultaneously identified, and thus the SFDA (State Food and Drug Administration) approval number is obtained; by calling a medicine information interface provided by the internet, the SFDA (State Food and Drug Administration) approval number obtained after identification is uploaded, the medicine information is returned, and reading is carried out. With the adoption of the method, old people, blind people, people suffering from visual impairment and illiterate people can read the medicine specification conveniently, and meanwhile, the information can be played through voice, so that the living quality of the people is improved.

Description

technical field [0001] The invention relates to the technical field of identification of drug instructions, in particular to a method for automatically identifying and reading aloud drug instructions. Background technique [0002] In China, there are 17.31 million visually impaired people, accounting for 18% of the total number of blind people in the world. Blind and low-sighted friends have many inconveniences in life. Reading and reading newspapers, which are easy for us ordinary people, are extremely difficult for them. Nevertheless, there are some books and newspapers in Braille that they can learn to read. However, drug instructions generally do not have Braille, and there is really no way when they need medication. [0003] At present, China's elderly population has exceeded 200 million, and the degree of aging is further deepening. The elderly also often deal with drugs in their daily lives. Their eyesight is generally not good, and the text on the drug instruction...
