问题描述 / Problem Description

配置如下：

        "Global.max_side_len": 2400,
        "Det.thresh": 0.5,
        "Det.box_thresh": 0.2,
        "Det.unclip_ratio": 1.5,
        "Det.use_dilation": False,
        "Det.engine_type": EngineType.ONNXRUNTIME,
        "Det.lang_type": LangDet.CH,
        "Det.model_type": ModelType.MOBILE,
        "Det.ocr_version": OCRVersion.PPOCRV4,
        "Rec.engine_type": EngineType.ONNXRUNTIME,
        "Rec.lang_type": LangRec.CH,
        "Rec.model_type": ModelType.MOBILE,
        "Rec.ocr_version": OCRVersion.PPOCRV5,

如下图，“当日盈亏”识别成了“当盈亏”

原图如下：

其它的“当日”，调整这张图的清晰度，都可能会“日”字丢失

我这里用rapidocr==3.9.0，就没有这个问题了。你那里可以试试最新的版本不？

from rapidocr import RapidOCR

engine = RapidOCR()

img_url = "https://private-user-images.githubusercontent.com/9456005/613543504-d3ab7c38-c8fd-45ad-937e-5e6667a51c28.png?jwt=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.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.LivmhtC4ukKR_cs_fovbxSm0yYMRZtk-g7i86d0OQfc"

是跟我一样的参数吗？我升级到3.9.0也还是不行。

[SWHL]

直接安装rapidocr v3.9.0，跑我下面这个代码：

from rapidocr import RapidOCR

engine = RapidOCR()

img_url = "https://private-user-images.githubusercontent.com/9456005/613543504-d3ab7c38-c8fd-45ad-937e-5e6667a51c28.png?jwt=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.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.LivmhtC4ukKR_cs_fovbxSm0yYMRZtk-g7i86d0OQfc"

print(result)

result.vis("vis_result.jpg")

这样不就是用的默认参数么

[SWHL]

我用的是默认参数，就是写的这个

我在在线 Demo 上也不行啊

[joechan-cq]

这张图，“文”，“言”也会丢，直接在线 Demo 默认参数就会丢。 V4 det + V5 rec

V5 det + V5 rec

[SWHL]

用v6的试试吧
