Goals
To be able to create any number of android and iOS applications using one software component to scan and read passports MRZ codes using phone camera.
Summary
We created a project using opencv and tesseract using C++, Objective-C and Swift, got good results, but not good enough to read the MRZ text lines within a reasonable time frame and with the desired accuracy. We are able to find the text lines of the MRZ code, crop each line from a camera frame image and recognize characters with tesseract.
We believe to improve the results what should be done is:
- Pre-process the images to improve tesseract results (deskew, 1-bit, unsharp masking)
- Train tesseract using the correct font (OCR-B);
- Use multiple results to successfully read all the fields and verify each check digit;
Objectives
Develop a software component that allows an app developer to create an app with passport reading capability without any knowledge of computer vision and OCR;
Write a sample application using swift or objective-c and compatible with iOS 8+ and android that uses the specified component to start the passport scan and receives the result of the processing;
Deliverables
1) Sample application with source code;
2) Framework/library used to scan passports, Identity cards, Visas built for and available to be used on iOS 8+ and android projects;
Basic architecture that should be followed
Method to start the scanning;
Input:
- timeout: (int) // in seconds;
Output:
- lines // read strings of MRZ code;
- success: boolean; // true if all the information was read and all the check digits verified;
- firstRowSuccess; // true if the first row complies with expected structure
- passportType;
- country;
- surName;
- givenNames;
- passportNumber;
- passportNumberSuccess; // true if the passportNumber check digit is verified;
- nationality;
- birth;
- birthSuccess; // true if the birth check digit was verified;
- sex;
- expirationDate;
- expirationDateSuccess; // true if the expirationDate check digit is verified;
- personalNumber;
- personalNumberSuccess; // true if the personalNumber check digit is verified;
- secondRowSuccess; // true if the last check digit is verified;
- thirdRowSuccess; // true if the last check digit is verified;
Details
- When the scan method is called the user will see the live camera;
- User will not be requested to do anything different from filming the passport (no button to take picture, for example);
- As soon as a successful result is available or the timeout is reached the user will be redirected to the screen he was before and the method will return its results;
- Even if the result is not successful the method shall return what was read. The boolean outputs (success, firstRowSuccess, passportNumberSuccess, birthSuccess, expirationDateSuccess, personalNumberSuccess, secondRowSuccess) will indicate success;
