OCR Software for Municipal Engineering Drawing with Stencil Written Character Processing

ExperVision’s OCR Software for Municipal Engineering Drawing with Stencil Written Character Processing also called Extracting & Vectorizing Application (EVA), which will include three modules, Automatic Extracting, Semi-Automatic Extracting, and Automatic Vectoring.

1. Automatic & Semi-Automatic Extracting

Extracting includes extracting character’s value and its coordinates.

  • Automatic Extracting means using ExperVision OCR SDK to LOCATE the character areas and RECOGNIZE the character automatically. The two functions LOCATE and RECOGNIZE can be done in one step (As “a” illustrates). As well, the two functions can be done by two steps. Firstly, click button to Automatic LOCATE character areas, then click button to Automatic RECOGNIZE the characters in located areas (As “b” and “d” illustrate)
  • Semi-Automatic Extracting means using ExperVision OCR SDK to Automatic LOCATE +Manual LOCATE “c” + Automatic RECOGNIZE (As “b” + “c” + “d” illustrate). If the recognized results were not correct, user could Manual ENTRY the character value (As “e” illustrate)

2. Automatic Vectoring

Automatic Vectoring means automatically convert raster images to vector images (as “f” illustrated). User could use one button click to convert raster image to vector image, which will display the object information.

3. Module Data Integration

Extracting & Vectorizing Application will extract character value and according coordinates of character area to database “D”. When the character areas were located, EVA will compute its coordinates and write it to the database. Together with vectorized images, the character value and coordinates will be output and imported into Client’s systems.
