camera_checker: Ensure cols + rows are in correct order (#319) Without this commit, specifying a smaller column than row size lead to huge reported errors: ` $ rosrun camera_calibration cameracheck.py --size 6x7 --square 0.0495 Linearity RMS Error: 13.545 Pixels Reprojection RMS Error: 22.766 Pixels $ rosrun camera_calibration cameracheck.py --size 7x6 --square 0.0495 Linearity RMS Error: 0.092 Pixels Reprojection RMS Error: 0.083 Pixels ` This commit switches columns and rows around if necessary.

Changed flags CV_LOAD_IMAGE_COLOR by IMREAD_COLOR to adapt to Opencv3. (#252)
Fixed stereo calibration problem with chessboard with the same number of rows and cols by rotating the corners to same direction.
Contributors: jbosch

properly save bytes buffer as such This is useful for Python 3 and fixes #256.
Get tests slightly looser. OpenCV 3.2 gives slightly different results apparently.
Use floor division where necessary. (#247)
Fix and Improve Camera Calibration Checker Node (#254) * Fix according to calibrator.py API * Add approximate to cameracheck
Force first corner off chessboard to be uppler left. Fixes #140
fix doc jobs This is a proper fix for #233
During stereo calibration check that the number of corners detected in the left and right images are the same. This fixes ros-perception/image_pipeline#225

remove camera_hammer and install Python nodes properly camera_hammer was just a test for camera info, nothing to do with calibration. Plus the test was basic.
Correct three errors that prevented the node to work properly.

replace Queue by deque of fixed size for simplicity That is a potential fix for #112

Update calibrator.py bugfix: stereo calibrator crashed after the signature of the method for the computation of the epipolar error changed but the function call was not updated
Contributors: Volker Grabe

install scripts in the local bin (they are now rosrun-able again) fixes #93
fix default Constructor for OpenCV flags this does not change anything in practice as the flag is set by the node. It just fixes the test.

make sure the GUI is started in its processing thread and fix a typo This fully fixes #85
fix bad call to save an image
have display be in its own thread that could be a fix for #85
fix bad usage of Numpy fixes #89
fix asymmetric circle calibration fixes #35
add more tests
improve unittests to include all patterns
install Python scripts properly and fixes #86
fix typo that leads to segfault fixes #84
also print self.report() on calibrate ... allows to use the params without having to commit them (e.g. for extrensic calibration between to cameras not used as stereo pair)
fixes #76 Move Python approximate time synchronizer to ros_comm
remove all trace of cv in Python (use cv2)
remove deprecated file (as mentioned in its help)
fixes #25 This is just removing deprecated options that were around since diamondback
fixes #74 calibrator.py is now using the cv2 only API when using cv_bridge. The API got changed too but it seems to only be used internally.
