推荐答案

OCR可能占用大量CPU，因此您可能需要重新考虑在智能手机上进行此操作.

OCR can be pretty CPU intensive, you might want to reconsider doing it on a smart phone.

此外，据我所知，流行的OCR库是 Aspire 和 Tesseract .两者都不是Java的直接版本，因此您不会获得直接使用的Android OCR库.

That aside, to my knowledge the popular OCR libraries are Aspire and Tesseract. Neither are straight up Java, so you're not going to get a drop-in Android OCR library.

但是，Tesseract是开源的(GitHub托管了)；因此您可以花一些时间将所需的子集移植到Java.我的理解是它的不是疯狂的 C ++，所以根据您对OCR的需求量的不同，这可能是值得的.

However, Tesseract is open source (GitHub hosted infact); so you can throw some time at porting the subset you need to Java. My understanding is its not insane C++, so depending on how badly you need OCR it might be worth the time.

答案很简短:否.

长答案:如果您愿意为此工作.

Long answer: if you're willing to work for it.
