OpenCV C++基于AI模型的场景文本识别(OCR)

这个程序使用OpenCV识别场景中的文本。输入图片程序运行后会在CMD里打印图片的识别结果代码#include iostream #include fstream #include opencv2/imgproc.hpp #include opencv2/highgui.hpp int main() { Mat image imread(/path/to/text_rec_test.png); TextRecognitionModel model(path/to/crnn_cs.onnx); model.setDecodeType(CTC-greedy); std::ifstream vocFile; vocFile.open(path/to/alphabet_94.txt); String vocLine; std::vectorString vocabulary; while (std::getline(vocFile, vocLine)) { vocabulary.push_back(vocLine); } model.setVocabulary(vocabulary); double scale 1.0 / 127.5; Scalar mean Scalar(127.5, 127.5, 127.5); Size inputSize Size(100, 32); model.setInputParams(scale, inputSize, mean); std::string recognitionResult recognizer.recognize(image); std::cout recognitionResult std::endl; }crnn_cs.onnx下载地址:https://drive.google.com/uc?exportdowloadid12diBsVJrS9ZEl6BNUiRp9s0xPALBS7ktalphabet_94.txt下载地址:https://drive.google.com/uc?exportdowloadid1oKXxXKusquimp7XY1mFvj9nwLzldVgBR
