Vision Using VDSP Vision Using LabView

Lab 5: Vision

Assigned: Friday, October 12, 2007.
Due: Monday, October 22, 2007.

In this lab, you will develop an algorithm to detect yellow and pink eggs, and program your robot hunt them down.

Introduction

  • explanation of OV7620 camera 320x240 pixels
  • discussion of YUV color space; see http://en.wikipedia.org/wiki/YUV
  • each camera row is alternately YU pixels and YV pixel -- 160 of each per row
  • each row is a 16-bit word - split into upper and lower byte to extract Y (brightness) or U/V (color) bytes

Practical Method

code is in Vision Using VDSP and Vision Using LabView

  • Use VDSP project to see frame
  • Extend LabVIEW VI OV7620 test project.vi (with project file vision_test.lvproj) to implement your algorithm
  • Save results in globals per frame
  • Act on the globals
