(vision): fix ARCalibration extrinsec view to add camera images autoresize
Summary
When making use of ArCalibration to compute an extrinsic calibration, two video flux are displayed. However, the images are not displayed completely, and, for some camera and resolutions, a big part of the image is cropped. THis behavior is present too when opening an acquired image, and only part of them are visible.
Steps to reproduce
Open ARCalibration Do an extrinsec calibration. For better reproduction conditions, make use of realsense cameras. Launch the two camera for the extrinsec calibration. Acquire one or two images with a board. Open the acquired images
What is the current bug behavior?
Both images of the camera during the acquisition and after when re-opened, are cropped, and only a part of them is vvisible.
What is the expected correct behavior?
It should be possible to seen the whole camera view.
Relevant logs and/or screenshots
Possible fixes
It seems that the basic camera calibration adapts the camera image to the size of the display panel. A similar system could be a solution. With the previous application based on vtk, the similar step allowed an "unzoom" option, which added a manual step, though gave an option to visualize the full camera view. This behavior could be a solution too.
