• Time: 2001/9–2003/3
• Research Center of Intelligent Robotics of Shanghai Jiao Tong University, China
• Project Description:
  • An active vision system is one that can manipulate the viewpoint of the camera(s) in order to investigate the environment and get better information from it. The project aims to develop an high performance embedded active vision system that can fulfill some challenge active vision tasks, such as tracking fast moving objects.
  • Programming Languages: Assembly language and C
  • Hardware Languages: VHDL
  • Development Tools: TI Code Composer Studio (CCS) for TMS320C6711 DSP programming, Protel for PCB design, Keil C51 for C51 MCU programming, AutoCAD for the mechanism design and MAX+PLUS for Altera's CPLD
• Responsibilities: Took charge of the whole project which includes implementation of image capture/processing/display hardware, the step motor control hardware, the pan/tilt camera mechanism and object recognition and tracking software.
