这个程序演示Tesseract OCR按块切图。不仅显示识别结果还找出每行文本的bounding box(边界框/包围盒)。输入图片程序运行后会在CMD里打印识别结果解释一下在图片里找到了8行文本。矩形边界框0的左上角坐标是(31,87),宽度是554,高度是40,置信度是94.把矩形框绘制到输入图片里大概就是这样代码#include tesseract/baseapi.h #include leptonica/allheaders.h int main() { char *outText; tesseract::TessBaseAPI *api new tesseract::TessBaseAPI(); // Initialize tesseract-ocr with English, without specifying tessdata path if (api-Init(NULL, eng)) { fprintf(stderr, Could not initialize tesseract.\n); exit(1); } Pix *image pixRead(phototest.tif); api-SetImage(image); Boxa* boxes api-GetComponentImages(tesseract::RIL_TEXTLINE, true, NULL, NULL); printf(Found %d textline image components.\n, boxes-n); for (int i 0; i boxes-n; i) { BOX* box boxaGetBox(boxes, i, L_CLONE); api-SetRectangle(box-x, box-y, box-w, box-h); char* ocrResult api-GetUTF8Text(); int conf api-MeanTextConf(); fprintf(stdout, Box[%d]: x%d, y%d, w%d, h%d, confidence: %d, text: %s, i, box-x, box-y, box-w, box-h, conf, ocrResult); boxDestroy(box); } // Destroy used object and release memory api-End(); delete api; delete [] outText; pixDestroy(image); return 0; }
