Embodiment 1

[0108] For some of the text on the medicine, it is also very convenient to directly scan and read aloud. For some medicines, the doctor directly writes the prescription, writes on the paper, or packs the special medicine in the paper bag. The usage and dosage are marked on the paper bag, but there is no printed drug description or QR Code. Therefore, in this embodiment, CIS is directly used to scan part of the text of the drug description.

[0109] The technical solution adopted in the direct text recognition scheme is: scan the drug description text through CIS or camera; recognize the text to obtain the information represented by the text; send the Unicode code of the text to TTS for reading aloud.

[0110] Among them, the process of character recognition is as follows: image 3 Shown: binarization, skew correction, character image enhancement, line segmentation, character segmentation, character image normalization, stroke division and feature matching.

[0111] In order t...

Embodiment 2

[0118] The technical scheme adopted for the image recognition scheme of generating QR Code from drug description text is as follows:

[0119] 1. The Android APP will generate a QR Code from the input drug description and other text;

[0120] 2. The Android APP sends the generated QR Code to the printer via Bluetooth for printing;

[0121] 3. CIS or camera to scan the image;

[0122] 4. The main control board converts the voltage value into a pixel value through an ADC;

[0123] 5. The main control board performs simple filtering and binarization on the QR Code image;

[0124] 6. The main control board linearly scales the QR Code image to obtain the QR Code bit stream;

[0125] 7. The main control board decodes the obtained bit stream according to the coding standard of QR Code;

[0126] 8. The main control board sends the decoded information to TTS through one UART for reading.

[0127] 9. The present invention does not involve the installation or application of the QR Co...

Abstract

The invention provides a drug description text reading method based on an image. The method comprises the following steps: 1, drug description information is acquired through a contact-type image sensor (CIS) or a camera; 2, the acquired drug description information is recognized to obtain a drug description text; and 3, the drug description text is read. The CIS or the camera is used to serve as a hardware terminal for image scanning, a scanning result is finally presented in a voice reading mode, and the reading problem of the aged can be effectively solved; and the hardware terminal does not involve an intelligent mobile phone APP, and thus software updating or upgrading is not needed. In society with increasingly serious aging, the method and the system provided by the invention aim at facilitating reading of the aged, and phenomena of misuse of drugs and excessive intake of drugs can be prevented. As the CIS or the camera and the peripheral circuit are regarded as a terminal, carrying is convenient, and the operation is simple.

Description

technical field [0001] The invention belongs to the field of image processing and communication, and in particular relates to an image-based method and system for reading drug explanatory text. Background technique [0002] At present, among the medicines on the market, since the medicine bottles need to cover more medicine instructions and dosage instructions, the fonts on most medicine bottles are compressed smaller. Very inconvenient to read. Mistake and overdose of medicines are prone to problems. [0003] The traditional solution is to use the mobile phone APP to identify text or images. At present, the disadvantage of using QRCode scanning APP in most smart phones is that most mobile phone APPs still present the scanning results in the form of text. For many elderly people For the elderly, there are still reading problems; the mainstream smartphone APP is updated quickly, and for the elderly, it is inconvenient to operate, and there are often phenomena such as the el...
