Gosseract is not running
php小编西瓜推荐的光学字符识别(OCR)工具Gosseract,是一款功能强大的开源OCR库。它基于Tesseract引擎,能够识别多种语言的文字,并提供了简单易用的接口。然而,有些用户在使用Gosseract时可能会遇到"未运行"的问题。本文将为大家详细解答这个问题,并给出解决方案,帮助大家顺利运行Gosseract工具,实现高效的OCR文字识别。
问题内容
# github.com/otiai10/gosseract/v2
tessbridge.cpp:5:10:致命错误:leptonica/allheaders.h:没有这样的文件或目录
5 | #include
下面是我写的代码
它给出了一个错误。我重新安装了 tesseract-i,它仍然给出相同的错误
package main import ( "fmt" "github.com/otiai10/gosseract/v2" ) func main() { client := gosseract.NewClient() defer client.Close() client.SetImage("C:\\Users\\labusers\\Downloads\\khan.png") text, _ := client.Text() fmt.Println(text) }
解决方法
安装 tesseract 可能很棘手。以下 dockerfile 有效:
FROM golang:1.14.9 RUN cat /etc/os-release # Output: Debian GNU/Linux 10 (buster) RUN apt-get -qy update RUN apt-get install -qy libleptonica-dev libtesseract-dev RUN apt-get install -qy libtool m4 automake cmake pkg-config RUN apt-get install -qy libicu-dev libpango1.0-dev libcairo-dev RUN cd /opt && git clone https://github.com/tesseract-ocr/tesseract WORKDIR /opt/tesseract RUN git reset --hard 4.1.1 RUN ./autogen.sh &&\ ./configure --enable-debug LDFLAGS="-L/usr/local/lib" CFLAGS="-I/usr/local/include" RUN make -j 8 RUN make install && ldconfig RUN tesseract --version ENV TESSDATA_PREFIX=/usr/local/share/tessdata ENV TESSDATA_REPO=https://github.com/tesseract-ocr/tessdata_best WORKDIR ${TESSDATA_PREFIX} RUN wget -q ${TESSDATA_REPO}/raw/4.1.0/eng.traineddata
dockerfile 从源代码构建 tesseract,以便您可以选择 tesseract 版本。这个dockerfile是我2年前使用gosseract
库时写的。
