[英]JavaCV cvInRangeS Error
我正在嘗試過濾掉圖像中的輪廓。 我的代碼沒有語法錯誤,但是我在運行程序時只得到很多紅色文本。 我確定了失敗的要點是cvInRangeS。
cvInRangeS(imghsv,minc,maxc,imgbin);
您可以通過println語句看到它,僅使其變為“ thourgh3”
square.jpg在項目目錄中,因此如果有幫助,就不應該成為問題。
控制台返回
Through 1
Through 2
Through 3

完整的代碼如下
package opencv2;
/*There are import statments here but for the sake of space I have left them out :D*/
public class OpenCV2 {
public static void main(String[] args) {
IplImage img1;
IplImage imghsv;
IplImage imgbin;
CvScalar minc = cvScalar(95,150,75,0), maxc = cvScalar(145,255,255,0);
CvSeq contour1 = new CvSeq(), contour2;
CvMemStorage storage = CvMemStorage.create();
double areaMax = 1000, areaC = 0;
System.out.println("Through 1");
img1 = cvLoadImage("square.jpg");
imghsv = cvCreateImage(cvGetSize(img1),8,3);
imgbin = cvCreateImage(cvGetSize(img1),8,3);
System.out.println("Through 2");
cvCvtColor(img1,imghsv,CV_BGR2HSV);
System.out.println("Through 3");
cvInRangeS(imghsv,minc,maxc,imgbin);
System.out.println("Through 4");
cvFindContours(imgbin,storage,contour1,Loader.sizeof(CvContour.class),
CV_RETR_LIST, CV_LINK_RUNS,cvPoint(0,0));
contour2 = contour1;
System.out.println("Through 5");
while(contour1 != null && !contour1.isNull()){
areaC = cvContourArea(contour1,CV_WHOLE_SEQ,1);
if(areaC > areaMax){
areaMax = areaC;
}
contour1 = contour1.h_next();
}//end of while
while(contour2 != null && !contour2.isNull()){
areaC = cvContourArea(contour2,CV_WHOLE_SEQ,1);
System.out.println("Through 6");
if(areaC < areaMax){
cvDrawContours(imgbin,contour2,CV_RGB(0,0,0),CV_RGB(0,0,0),
0,CV_FILLED,8,cvPoint(0,0));
}//end of if
System.out.println("Through 7");
contour2 = contour2.h_next();
}//end of while2
System.out.println("Through 8");
cvShowImage("Color",img1);
cvShowImage("CF",img1);
cvWaitKey();
cvReleaseImage(img1);
cvReleaseImage(imghsv);
cvReleaseImage(imgbin);
cvReleaseMemStorage(storage);
}//end of main
}//end of class
cvInRangeS()
假定輸入圖像的類型為CV_8U
,因此您必須先對其進行轉換。
...
cvtColor(imghsv, grayscale, CV_BGR2GRAY );
cvInRangeS(grayscale,minc,maxc,imgbin);
...
謝謝你的幫助。 問題是在這一行中,我將其設置為3通道圖像“ 3”。imgbin = cvCreateImage(cvGetSize(img1),8,3);
它應該是一個二進制映像。 imgbin = cvCreateImage(cvGetSize(img1),8,1);
