有打算开发一个将识别的边缘顶点直接返回给用户的接口，和根据边缘顶点来截取和透视处理图片的接口吗？

楼主 你好 有iOS版吗

当库识别出对应的证件的四边形的区域的时候，是否可以获取边框上下左右四个坐标点，我需要裁掉图片中多余的留白。现在源代码好像只是识别到的时候，直接调用cameraview.takephoto()截图，谢谢！

如果不是银行卡，身份证，别的矩形边框能不能自定义识别呢？

问题2：后台处理与前端同步显示

• 请问如何将后台处理的线程的结果与UI的绘制线程友好的链接起来
  比如：后台处理得到文档的四个顶点，如何将这些顶点坐标正确传给绘图层？blog中的
  processHandler.sendEmptyMessage(1);
  交给后台处理，这是并发性的，如何将处理结果同步显示到绘图？

问题1： 程序与blog的问题

首先感谢Android 端相机视频流采集与实时边框识别中提到的一些思路，奇怪的发现github中的程序并未使用blog中提到的策略，比如：SmartCameraView.java （49~69行）

private void init() {
        smartScanner = new SmartScanner();
        uiHandler = new ScanResultHandler(this);
        addCallback(new CameraImpl.Callback() {
            @Override
            public void onPicturePreview(CameraImpl camera, byte[] data) {
                super.onPicturePreview(camera, data);
                if (data == null || data.length == 0 || !scanning) {
                    return;
                }
                int previewRotation = getPreviewRotation();
                Size size = getPreviewSize();
                Rect revisedMaskRect = getAdjustPreviewMaskRect();
                if (revisedMaskRect != null && size != null) {
                    int result = smartScanner.previewScan(data, size.getWidth(), size.getHeight(), previewRotation, revisedMaskRect);
                    uiHandler.obtainMessage(result, data).sendToTarget();
                }
            }
        });
    }

这里没用到后台处理的操作吧？

作者你好：demo裁剪出来的图片不是扫码框内的部分 是不是以下代码需要对原始数据进行方向判断并转换方向？麻烦了
@OverRide
public void onPictureTaken(CameraView cameraView, byte[] data) {
super.onPictureTaken(cameraView, data);
//TODO data的方向与预览的不一致
mCameraView.cropImage(data, new SmartCameraView.CropCallback() {
@OverRide
public void onCropped(Bitmap cropBitmap) {
if (cropBitmap != null) {
showPicture(cropBitmap);
}
}
});
}

你好！我在三星S7edge测试过 竖屏比横屏的识别速度快很多，识别率高很多，应该怎样设置 横屏的参数，还是可以再优化一下。
场景是身份证放在接近白色的黄色桌面上。

想请问大神如何解决、我在公众号给大神留言了、大神求指导

何时兼容camera2？

需要调整哪些参数可以让识别的证件能尽可能的不出现白边呢？

如题

你好，博主有QQ群或者qq吗？我用的一体机，宽高和手机相反，宽高比也不对，不能达到系统相机的效果，请问怎么设置呢？

你好，看之前的问题，找到一个x86文件夹下的so库，但是这里报错要x86_64下面的so库，我编译通不过了，这个有没有别的办法可以解决的？

我要怎么做？

您这两个项目我都没运行起来。

还有,你这个库我要怎么引用到自己的项目里？能简单说下吗？
单独导入您的lib module不行，试过了。

360 安装APK 启动崩溃

这边不混淆之前打包有44M。。。我真的是惊呆了。真的有这么大么

是否计划开发去掉opencv版本？因为目前好多开发商对于APK大小有严格的要求

如果有，能否说明下具体如何配置

你好！maskView.setMaskRadius 方法连中间的动态扫描线也设置了圆角！请问这个会修复不？

作者你好！我是在使用1.3.2的时候发现，魅族的机都会报这个错误

目前只发现魅族会出错（魅族15，魅族pro6s和魅蓝metal）

没有导入源码，是新建工程，用添加依赖的方式引用你的库。
在 Android 8.0上正常。
在Android 4.1.2 和 4.2 上启动崩溃。报以上错误。

请指教该如何处理.

布局中尝试android:background="@null"
代码中添加@OverRide
public void setBackgroundDrawable(Drawable background) {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N && background != null) {
setBackgroundDrawable(background);
}
}
建议作者在源码中添加上,不然引入依赖后再android 7.0 以上的机械上崩溃

能不能改为横向模式呢

minSdkVersion最小值是15可以吗

I am currently using try catch to fix this error.

====== update =====
No, try catch can't fix. I am trying something else to solve.

=== 2019年3月2日 12:38:51 ===
Reference this link: https://stackoverflow.com/a/32245018/8920453
I add below entities in my manifest file android:hardwareAccelerated="false" , android:largeHeap="true".

There is no problem for now.

点击拍照报
Camera is not ready. Call start() before takePicture().

拍出来的照片跟预期的向左旋转了90度，
在华为麦芒的手机上测试是正常的

mCameraView.setOnScanResultListener(new SmartCameraView.OnScanResultListener() {
@OverRide
public boolean onScanResult(SmartCameraView smartCameraView, int result, byte[] data) {
// Bitmap previewBitmap = smartCameraView.getPreviewBitmap();
if (result == 1) {
LogUtils.i("onScanResult()--->>>");
mCameraView.cropJpegImage ....
return true;
}
return false;
}
});

模板不同，都得自定义模板吗？有点麻烦，能否直接传对应的图片或者bitmap的方法提供呢？
