如何将 OCR 与 Expo 集成

Question

我尝试使用各种库（例如react-native-tesseract react-native-text-detectorExpo 中的库）来集成 OCR，但它们不起作用。这是我的代码，我想知道如何在其中集成 OCR。预先感谢您的解决方案！

  takePicture = async () => {
    if (this.camera) {
      const options = { quality: 0.5, base64: true };
      const data = await this.camera.takePictureAsync(options);
      this.runOcr(data.uri);
    }
  };

  runOcr = async (imageUri) => {
    //code here
  };
    return (
      <>
        <Camera
          ref={(ref) => {
            this.camera = ref;
          }}
          style={{
            flex: 1,
            position: "absolute",
            width: "100%",
            height: "100%",
          }}
          type={Camera.Constants.Type.back}
          autoFocus={Camera.Constants.AutoFocus.on}
          flashMode={
            !this.state.isFlash
              ? Camera.Constants.FlashMode.off
              : Camera.Constants.FlashMode.on
          }
        />
        <View
          style={{
            position: "absolute",
            bottom: "5%",
            display: "flex",
            alignItems: "center",
            justifyContent: "space-between",
            width: "100%",
            flexDirection: "row",
          }}
        >
          <TouchableOpacity onPress={this.takePicture}>
            <Image
              style={{ width: 90, height: 90 }}
              source={require("./assets/rec.png")}
            />
          </TouchableOpacity>
        </View>
      </>
    );

runOcr 是发生 OCR 的函数，但是我删除了 OCR 代码。
