Coordinates not displayed using cornerPhoto #15

Closed VisionaryMind closed 3 years ago

VisionaryMind commented 3 years ago

Using your sample data as a test, the cornerPhoto launch file opens the first image, but no coordinates are displayed:

Where can the setting be found for enabling coordinate display?

This is a problem with not having OpenCV 4 in Ubuntu 18.04. ROS Melodic uses OpenCV 3.2 by default, so it is necessary to uninstall the Core 3.2 libopencv libraries and manually compile the ROS workspace for OpenCV4.
