2016-03-31 13:36:12 -0500	asked a question	make ar drone 2.0 follow a path Hi everybody, The first part of my project was to make an ar drone 2.0 follow a person basing on the color of his/her t-shirt. I have managed to complete this part but, now, I have moved to the second part of the project. In this part, I have to make a second drone follow the path of the first one without following any person and avoiding obstacles after the first drone finishes its path. I thought of two solutions: Motion vector could be computed through the optical flow between one frame from the stream video (second drone) and one frame from the stored video (it comes from the first drone). Using odometry to get the position and extrapolate the path of the first drone. Then, transfer the path to the second drone and make it follow that path. Do you think these methods could bring to the result I wish? Any further advice would be well appreciated!
