| titleOfInvention | Method and apparatus for calibrating three-dimensional space for machine vision applications |
| abstract | A calibration apparatus for calibrating three-dimensional space for a machine vision system and a method for using the calibration apparatus for calibrating the machine vision system are disclosed. The calibration apparatus comprises pairs of indicators, such as lights, mounted on a frame, each pair of lights separated by a known horizontal distance. The calibration apparatus may be mounted on the back of a vehicle that moves the apparatus through a roadway scene at a known speed. A machine vision system tracks the calibration apparatus specifically the pairs of lights mounted on the frame, and maps the pixel space of the machine vision system to three-dimensional space. |
