Abstract
In recent years, with the population of surveillance system, motion detection and tracking objects are widely used in various places, such as commercial buildings, convenience stores, parking lots, and so on. It can replace some boring and time-consuming work. It can also avoid some mistakes due to our fatigue. Furthermore, when detecting emergency situations, the system can send messages immediately so that it can substantially reduce the system cost.
We expect that the system can detect and track objects which pass the scene using two cameras. Then we can use stereo vision to measure the distance according to the two tracking results. By doing so, we can get the space coordinates of moving objects and we can implement this system on TI’s DM642. For object detection we establish background by adopting progressive background, and detect the foreground. We also transfer the detected objects to color histogram when tracking. Then we use Particle Filter to track the position of objects. Finally, we find the likely points of two objects’ image to measure distance.
