It presents some characteristics of the human oculomotor system in active machine vision system: smooth pursuit and saccade. Besides, zoom tracking is used to continuous adjustment of a camera's focal length to keep a constant sized image of an object moving along the camera's optical axis. Experiments indicate the technology to be efficient for tracking the ball in the robot competition.展开更多

We have built a soccer robot system to participate in internal and oversea matches. Firstly, we propose a new learning control scheme adaptive PID learning controller. It means to overcome the drawbacks of the conventional PID type control methods. Secondly, we introduce our vision recognition algorithm. It remarkably increases the speed of recognition. Finally, we refer the communication system. We adopt bulletin board system to prevent communication confusion.展开更多

In order to improve rendering quality, it partitions visibility computation PVS preprocessing and runtime dynamic visibility computation, at the meantime level-of-detail models are managed to speed up the rendering. The method relies on the hierarchical spatial data structure (HSDS) of 3D objects in virtual environment. Compared with some classical speedup methods such as the graphic hardware method and a few typical software speedup techniques, the new method embodies obvious improvement in speedup performance.展开更多
