This study aims to develop an automated data digitization system for the Thai vehicle registration certificate. It is first developed as a web service Application Programming Interface (API), which essential any enterprise increase its business value. Currently, this available on “www.carjaidee.com”. The involves four steps: 1) embedded frame aligns document be correctly recognised in image acquisition step; 2) sharpening and brightness filtering techniques enhance quality are applied pre-processing 3) Google Cloud Vision API receives prompt proceed recognition 4) specific domain dictionary improve accuracy rate post-processing step. defines 92 images experiment by counting correct words terms from output. findings suggest that proposed method, had average of 93.28%, was significantly more accurate than original method using only API. However, limited because dictionaries cannot automatically recognise new word. In future, we will explore solutions problem natural language processing techniques.
