Abstract
(Received January 02 2018, accepted March 18 2018) Laser spot emitted by laser pointers were widely used in numerous fields such as pointing during presentations, guiding robots in human machine interaction (HCI), and guiding munitions to targets in military, etc. Our interest is to develop an effective method for laser spot detection and tracking with exploiting fewer features. In this paper, we jointly combined pyramid Lucas–Kanade (PLK) optical flow for detection and extended Kalman filter for accurately tracking laser spot in low-resolution and varying background video frames. Using this new technique, we only need to deploy intensity of laser spot with displacement of laser spot and get a very good result. This technique could be embedded into multi-core processing devices with inexpensive cost for potential high benefits in the future.
