Patent ID: 7768527

Claim:
A hardware-in-the-loop simulation system to verify computer vision, the system comprising: a virtual reality imaging unit that generates a virtual scene and an observed object using a virtual reality software, wherein virtual scene images of the scene at different viewpoints are obtained; a projector that projects the virtual scene images generated by the virtual reality software onto a screen; and a camera that shoots the virtual scene images projected by said projector on the screen, wherein the direction of the camera is controlled by a pan-tilt, wherein the camera is fixed on the pan-tilt, and wherein a position and orientation of the projector and the pan-tilt are fixed to the screen; wherein the virtual reality imaging unit comprises a first computer and wherein said projector connects to the virtual reality imaging unit; and wherein the camera sends image data gathered while shooting the projected scene images to a second computer by a frame grabber board and the second computer is configured to control the pan-tilt to select a proper direction for the camera to shoot the virtual scene images projected onto the screen.
