Detailed Description

Class that defines a 2D point in an image. This class is useful for image processing and stores only the 2D coordinates given in sub-pixel.

Warning
If you want to define a point thanks to its coordinates given in meter in the object frame, the camera frame or the image plane, you have to use the class vpPoint.

In this class, the 2D coordinates are not necessary integer values. It is easy to manipulate the given coordinates in the two frames used in ViSP : the (i,j) coordinates and the (u,v) coordinates. The two following images illustrate the two coordinate systems.

Warning
An instance of the vpImagePoint class corresponds to a particular point. Thus, if you change the point coordinate using the method set_i(double i), it produces the same effect than if you used the method set_v(double v). These two methods change the same private attribute. It is also true for the two methods set_j(double j) and set_u(double u).

[in]start: Segment start image point.
[in]end: Segment end image point.
Returns
Regarding current image point, next image point that belongs to the liSegmentne [start,end].

#include <iostream>
#include <visp3/core/vpImagePoint.h>
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
int main()
{
vpImagePoint start_pixel(10, 12);
vpImagePoint end_pixel(20, 16);
for (auto curr_pixel = start_pixel; curr_pixel.inSegment(start_pixel, end_pixel);
curr_pixel = curr_pixel.nextInSegment(start_pixel, end_pixel)) {
std::cout << "pixel: " << curr_pixel << std::endl;
if (curr_pixel == end_pixel) break;
}
return EXIT_SUCCESS;
}
VISP_NAMESPACE_NAME
Definition vpEigenConversion.h:44

It produces the following output by printing all the pixels belonging to the segment:

pixel: 10, 12
pixel: 11, 12.4
pixel: 12, 12.8
pixel: 13, 13.2
pixel: 14, 13.6
pixel: 15, 14
pixel: 16, 14.4
pixel: 17, 14.8
pixel: 18, 15.2
pixel: 19, 15.6
