How convert List<Mat> to MatofPoint2f with api java for opencv
Hi,
I am programming with the opencv api for java. And I'm trying to use the function findHomography.
Its input must to be a MatofPoint2f but I have a set of points like a List(Mat).
To convert the List(Mat) to Mat I try the code below.
But I get the error: "java.lang.IllegalArgumentException: Incompatible Mat" at line
MatOfPoint2f imagePoints2f_1 = new MatOfPoint2f(mat_aux);
CODE
imagePoints_1 and imagePoints_2 are List(Mat)
Mat mat_aux;
mat_aux = Converters.vector_Mat_to_Mat(imagePoints_1);
MatOfPoint2f imagePoints2f_1 = new MatOfPoint2f(mat_aux);
mat_aux = Converters.vector_Mat_to_Mat(imagePoints_2);
MatOfPoint2f imagePoints2f_2 = new MatOfPoint2f(mat_aux);
H = Calib3d.findHomography(imagePoints2f_1,imagePoints2f_2, Calib3d.LMEDS, 0.0);
you probably want to convert 1 item from your list<Mat> to a MatofPoint2f, not the whole list
@berak: Actually, I want to convert the whole list
I've the same problem. Kinda frustrating.
