find and draw chessboard for undistortion #73

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.

in opencv_calib3d.java

public static native int cvFindChessboardCorners(CvArr image, @ByVal CvSize 
pattern_size,
            CvPoint2D32f corners, int[] corner_count/*=null*/, 
            int flags/*=CV_CALIB_CB_ADAPTIVE_THRESH | CV_CALIB_CB_NORMALIZE_IMAGE */);

in native c function

int cvFindChessboardCorners(const void* image, CvSize patternSize, 
CvPoint2D32f* corners, int* cornerCount=NULL, int 
flags=CV_CALIB_CB_ADAPTIVE_THRESH)

2.
3.

What is the expected output? What do you see instead?
->  int[] corner_count  Vs  int *cornerCount
what should I put in here? I tried int[] corner_count; variable but it crashed. 
Overall codes are from "Learning OpenCV" by Gary & Adrian.(CH.11 Calibration)

What version of the product are you using? On what operating system?

Please provide any additional information below.

You put the same thing as you would put in C/C++. If you have a test case that 
fails, please post it. 

If this is not an issue with JavaCV and you simply do not know /how to use/ 
JavaCV, please post on the mailing list, thank you.

I am guessing the issue has been resolved...

I want to know how the function
cvFindChessboardCorners(CvArr image, @ByVal CvSize pattern_size,
            CvPoint2D32f corners, int[] corner_count/*=null*/, 
            int flags/*=CV_CALIB_CB_ADAPTIVE_THRESH | CV_CALIB_CB_NORMALIZE_IMAGE */);

find the corners ..when i print corners.x(),corners.y() ..it prints the last 
corner point of chessboard...how to find the rest

As explained in the README.txt file, use the Pointer.position() method, i.e.: 
corners.position(i) for the i'th point
