如何使用Tesseract OCR閱讀身份證中的單詞？

我正在使用Tesseract Library從身份證信息中讀取工作信息。我對每個單詞或每行有置信度分數。如何使用Tesseract OCR閱讀身份證中的單詞？

在這裏使用的代碼。

Pix *image = pixRead("/usr/src/tesseract-3.02/phototest.tif"); 
    tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI(); 
    api->Init(NULL, "eng"); 
    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); 
    }

現在我需要閱讀所有的身份card.But我設置的值的Tesseract :: RIL_TEXTLINE爲正方體:: RIL_WORD並運行代碼的話。即使是沒有形象的話，我也有很高的自信。
