CIDetector无法在iOS中检测到正确的Rectangle吗? [英] CIDetector not detecting proper Rectangle in iOS?

问题描述

我正在尝试使用CIDetector检测到Rectangle.

I am trying to detect a Rectangle using CIDetector.

我正在使用以下代码: https://www.cocoacontrols.com/controls/vnimagescanner

I am using code from this: https://www.cocoacontrols.com/controls/vnimagescanner

我的问题是，当我尝试检测任何Rectangle对象时，有时它正在检测或有时它正在检测Odd Rectangle(请参见下图).我试图搜索此Google，但没有找到任何解决方案.

My problem is when I am trying to detect any Rectangle object, sometimes it's detecting or sometimes it's detecting Odd Rectangle (please see below images). I tried to search this Google but didn't find any solution of this.

正常情况:

Normal case:

一些不好的情况:

Some bad case:

这是我设置CIDetector Accuracy的代码:

func highAccuracyRectangleDetector() -> CIDetector? {
   var detector: CIDetector? = nil
   detector = CIDetector(ofType: CIDetectorTypeRectangle, context: nil, options: [CIDetectorAccuracy: CIDetectorAccuracyHigh, CIDetectorAspectRatio: 1.43, CIDetectorMaxFeatureCount: 5])

   return detector
}

如果您要看第三张图像，它会突出显示而没有Rectangle对象.

If you will look into third image, it's highlighting without Rectangle object.

当有适当的Rectangle时，是否可以检测或显示突出显示的绿色覆盖物?请建议我.

Is it possible to detect or to display the highlighted green overlay when there will be a proper Rectangle? Please suggest me.
