We had a conversation with Professor Diorio (Our project manager). The scope of the project has been brought done to size and we have identified the major areas we need to focus on. Our primary focus is on getting the camera working (i.e. understanding the interface and to program agains the interface.) The second primary focus is to process the camera data.

  • RF Interface: We blieve RF will be easy to interface. We will look into how the RF monolithic boards work. We have three choice for User Interaction.
  • Marker Implementation: We have defined what the marker will be. Because the camera processes intensity images well, we felt something that had an extreme local itensity difference would work the best. We plan then to use a laser pointer which will shine its light against a white background. This would be a movable unit that can be placed in any location that the user wants. This now simplifies the image analysis capture. We can look for a large intensity difference against a white background.
  • Floatin-point Emulation: Floating-point emulation is a possibility. Previously, we thought that the atmel 8051 will be handling the floating-point arithmetic. Under this scenario, we didn't want to run floating-point emulation because it would be costly. Looking at the possible final implementation, we found that the XSV-300 would be handling the floating-point computations. Thus creating a floating-point units in hardware would be simple.
