 The cost-efficiency of visual SLAM is crucial for target applications in Robotics and VR/AR.  One principal enforced in this project is to persue better computation-performance trade-off in both front-end and back-end of visual SLAM.  To that end, three major algorithmic innovations are integrated to ORB-SLAM 2:
