OpenCV cvBoundingRect应用举例

最近在用OpenCV做一个项目，查找cvBoundingRect时候没有找到比较好的例子，在此为了方便大家，贴出一段代码利用cvBoundingRect的例子。

CvMemStorage* storage1 = cvCreateMemStorage( 0 );
	CvSeq* contour = NULL;
	IplImage *imgTemp = cvCloneImage( dilateImage );		
	cvFindContours( imgTemp, storage1, &contour, sizeof( CvContour ), CV_RETR_CCOMP, CV_CHAIN_APPROX_NONE);

	int ContoursCount = 0;

	IplImage *TrangleImage = cvCloneImage(inTopView);

	int height  =TrangleImage->height;  
	int width   =TrangleImage->width;  
	int step    =TrangleImage->widthStep;  
	int channels=TrangleImage->nChannels; 

	outCarSegment.CarRect.clear();
	for( ; contour != NULL; contour = contour -> h_next)
	{
		CvRect rect = cvBoundingRect(contour, 0);
		if (rect.width > 20 && rect.height > 20)
		{
			cvRectangle( TrangleImage, cvPoint( rect.x, rect.y ),cvPoint( rect.x + rect.width, rect.y + rect.height ), CV_RGB(255,0,0), 1, 8, 0);
			ContoursCount++;
			outCarSegment.CarRect.push_back(rect);
		}		
	}
	cvSaveImage("FindContours.png", TrangleImage);

我的这段例子只是取物体外边框，需要取物体内边框的可以参照找一篇文章：http://blog.csdn.net/honpey/article/details/8575507；
