Drawing OCR

Questionnaire for a service to make your drawings searchable through OCR and PDF technologies.

Scanned drawings and plans are raster files that can be stored and displayed on a computer. Many times they are converted to CAD (vector format) to be used to change the drawing. Drawing OCR is different: the scanned imge is automatically processed by a text recognition engine and hidden text entities are created. These text strings can be later searched on in a suitable repository (CMS) or just in the generated PDF file using Adobe Acrobat(tm). We would like to discover your problems and provide solutions with this method.

Original Drawings
Do you have the original hard copy or are they already scanned? Maybe you have digital originals?
Please explain:
We are interested in color space of your drawings. Drawing of map scanning can be done in B&W, Grayscale and Color format.
Please explain if you have specific requirements regarding color issues.
We would like to know the size of the drawings.
Please explain:
Please specify the number of drawing in thi project.







Please explain:
Drawing Condition
Using your best judgment, how would you characterize the overall condition of the drawings? Paper quality influences the scanning process.
Please explain in detail if needed
Please tell us more about your scanned files if applicable
Please explain in detail if needed
Drawing Preparation for Scanning
Are any pages in the project stapled together? Staples need to be removed before scanning.
Please note special requirements for handling staples in the project.
Are any pages in the project that are clipped together? Paper clips or clamps need to be removed before scanning.
Please note special requirements for handling paper clips in the project.
Barcodes are used to make the scanning and indexing process more efficient. They are used for many purpose (document, folder separation, bookmark creation, index entry, tracking of workflow, job ticketing etc...).
More description of barcode-specific information or requirement.
Some drawings are so fragile, that they are not able to withstand the scanning process and special methods need to be deployed. Some of the methods are scanning those pages in a plastic sleeve, ironing them, sticking post-it notes on a separate sheet etc... Please explain here in detail if this is the case.
Scanning of Drawings
We are using document and wide format scanners.
Please explain:
As a general rule, the practically feasible highest scanning resolution and color depth should be used.
Please specify:
Scanned Drawing Image Processing
Image Processing Requirements
What kinds of image processing do you require?
Deskew is a needed operation because of the scanning process introduces some level of skew. In addition, there is usually a skew in the original document due to printing and binding. The first image processing step is the high quality deskew that works with color, grayscale and B&W images. In addition to the advanced detection routines and the possibility of a QC step, the most important aspect is the interpolated rotation that protects images and text characters (no sheering effect).
Please specify:
Speckles are originated through a copying or scanning process and represent isolated small black image components (noise) that are not part of the original drawing. Speckles are removed by specifying a minimum and maximum (horizontal and vertical) size.
Please specify:
These are the most commonly used image processing operations, usually performed on B&W images.
Please specify:
Drawing Indexing and metadata
Metadata and Indexing Requirements
Please provide feedback for the indexing requirements.
Please tell us how your files are organized. The indexing requirements usually follow the physical layout of your documents.
Please explain:
The quantity and length of index fields enhances searching and organization, but it is a costly operation. Please specify how many index fields will be needed and how long is the average data length.




Please describe your needed index fields.
Please estimate the average length of all of the index fields.
The captured indexes (metadata) describe the captured files and can be released by a number of various methods. Please specify one or more options.
Please specify you specific requirements for metadata release:
File output of the drawing conversion process
Output Intent and Requirements
Please describe what kind of output requirements do you have for this project.
Please explain:
The paper documents will be converted to digital files. What will be the final goal of the conversion process?
Please explain:
PDF is the most popular choice these days, but other formats are supported as well.
Please explain:
Many advanced PDF features are supported at the conversion process. Additional features can be added to enhance the usability of the document.
Please explain:
Conversion Budget
What kind of engagement are you looking for?
Please explain:
Please tell us about your proposed schedule
