ROS Image Script #7

Open sjcantor opened 4 years ago

sjcantor commented 4 years ago

Current State

The image script currently reads in new images from the robot, converts it to a numpy array, displays it using openCV and saves it to a jpeg.

Next Steps

Need to figure out how to display this as a video instead of the current implementation, where you have to hold spacebar to replace the current image with a new one.
The image should be published to a new topic/node, and a new script will subscribe to that topic to perform object recognition

This issue has been fixed for the most part. Live feeds of the image with and without bounding boxes can be viewed in rviz or through iage_transport, but the stream with bounding boxes has a noticeable delay. Surprisingly, this delay is not bottle-necked by the deep learning model, but instead by the matplotlib figure and publishing node. Will look into more efficient ways of plotting boxes.
