| Summary: | 碩士 === 國立陽明大學 === 衛生資訊與決策研究所 === 94 === FDA was issuing a new rule to require certain human drug and biological product labels to have line bar codes. This will help reduce the number of medication errors in hospitals and other health care settings. Traditionally, the bar code readers used laser to scan bar code. This needed extra cost for the equipment to read the bar code. On the other way, using smartphone integrated camera to recognize visual tags is currently hot topic. Smartphone is a ubiquitous computing tool. With the phone and the camera, it give us a good opportunity to bring up an support system for care givers and the patients read and learn drug information just on their phone. This paper descripts a software support system for care givers and patients to identify the barcode use a camera phone. It is an economical and effective way if we can create software to help people to identify the barcode and show the information they need just on their phone.
The result shows that the correct percentage of each bar code number is 86.6%. The correct percentage of full bar code is 95%. We had considered the real situation in the hospital, sometimes the barcode maybe draw by the pen. We draw on the barcode and try to recognition it. The result shows that the correct percentage of this kind of bar code is 92%. As a result, we thanks our algorithm is very feasibility.
