Hi You can try resize the image and try again.

If your image width or height s greater than 2000， In C# Code

//The v3.0.0 is max_side_len

OCRParameter.max_side_len = 2000;

//if you use  a  other version,

OCRParameter.MaxSideLen= 2000;

In C++ code is "max_side_len".

and try again.

thank you

Hi,

I tried, but still it's same. Here I attached the Image for your reference.

Expected output: 99702000 292.0087 817618.000 2534 4B10P

If have the space in between the two character, split as separate line

Kindly help me to solve this

Thank you

You can try use the en_V3 model.

en_V3 model

Example of using c #

         OCRModelConfig config = new OCRModelConfig();
            string root = System.IO.Path.GetDirectoryName(typeof(OCRModelConfig).Assembly.Location);
            string modelPathroot = root + @"\en_v3";
            config.det_infer = modelPathroot + @"\en_PP-OCRv3_det_infer";
            config.cls_infer = modelPathroot + @"\ch_ppocr_mobile_v2.0_cls_infer";
            config.rec_infer = modelPathroot + @"\en_PP-OCRv3_rec_infer";
            config.keys = modelPathroot + @"\en_dict.txt";

Hi,

I cannot find any folder like @"\en_v3" and @"\en_dict.txt"

[raoyutian]

download url: https://gitee.com/raoyutian/paddle-ocrsharp/tree/dev/models/PP-OCRv3 and download the en_v3.zip

Thank you. It's helpful for me.

And If I have the flipped image, is it possible to get the correct OCR text.

[raoyutian]

你好，项目默认没有开启方向识别参数，对于可能存在旋转的图像或者有旋转角度的文字，你可以设置如下参数

OCRParameter.cls= true;
OCRParameter.use_angle_cls= true;

下面链接，有详细参数的使用说明 https://gitee.com/raoyutian/paddle-ocrsharp/blob/master/doc/UseInCsharp.md
