Detailed Description

The vpDisplayOpenCV allows to display image using the OpenCV library. Thus to enable this class OpenCV should be installed. Installation instructions are provided here https://visp.inria.fr/3rd_opencv.

Warning
Since ViSP 3.3.1 or higher we introduce the alpha channel support for color transparency. This new feature is only supported yet using vpDisplayOpenCV. See vpColor header documentation and displayOpenCV.cpp example for usage displaying filled transparent circles and rectangles.

The example below shows how to display an image with this video device.

#include <visp3/core/vpImagePoint.h>
#include <visp3/gui/vpDisplayOpenCV.h>
#include <visp3/io/vpImageIo.h>
int main()
{
#if defined(VISP_HAVE_OPENCV)
vpImage<unsigned char> I; // Grey level image
// Read an image in PGM P5 format
vpImageIo::read(I, "/local/soft/ViSP/ViSP-images/Klimt/Klimt.pgm");
// Initialize the display with the image I. Display and image are
// now link together.
d.init(I);
// Specify the window location
// Set the display window title
vpDisplay::setTitle(I, "My OpenCV display");
// Set the display background with image I content
// Draw a red rectangle in the display overlay (foreground)
vpDisplay::displayRectangle(I, 10, 10, 100, 20, vpColor::red, true);
// Draw a red rectangle in the display overlay (foreground)
vpImagePoint topLeftCorner;
topLeftCorner.set_i(10);
topLeftCorner.set_j(50);
vpDisplay::displayRectangle(I, topLeftCorner, 100, 20, vpColor::green, true);
// Flush the foreground and background display
// Get non blocking keyboard events
std::cout << "Check keyboard events..." << std::endl;
char key[10];
bool ret;
for (int i=0; i< 200; i++) {
bool ret = vpDisplay::getKeyboardEvent(I, key, false);
if (ret)
std::cout << "keyboard event: key: " << "\"" << key << "\"" << std::endl;
}
// Get a blocking keyboard event
std::cout << "Wait for a keyboard event..." << std::endl;
ret = vpDisplay::getKeyboardEvent(I, key, true);
std::cout << "keyboard event: " << ret << std::endl;
if (ret)
std::cout << "key: " << "\"" << key << "\"" << std::endl;
// Wait for a click in the display window
std::cout << "Wait for a button click..." << std::endl;
#endif

◆ vpDisplayOpenCV() [1/6]

vpDisplayOpenCV::vpDisplayOpenCV ( )

Basic constructor.

To initialize the window position, title and size you may call init(vpImage<unsigned char> &, int, int, const std::string &) or init(vpImage<vpRGBa> &, int, int, const std::string &).

#include <visp3/core/vpImage.h>

Display a rectangle with topLeft as the top-left corner and width and height the rectangle size.

Parameters
I: The image associated to the display.
topLeft: Top-left corner of the rectangle.
bottomRight: Bottom-right corner of the rectangle.
color: Rectangle color.
fill: When set to true fill the rectangle. When vpDisplayOpenCV is used, and color alpha channel is set, filling feature can handle transparency. See vpColor header class documentation.
thickness: Thickness of the four lines used to display the rectangle. This parameter is only useful when fill is set to false.
