Team 8 Real-Time Capture Display (RCD) Laser System Presented by Danny Barjum Team Members: Corey Lane, Ryan Scott & Danny Barjum
Project and PSSCs An ability to locate a laser pointer’s coordinates inside a given boundary using a camera. An ability to create an image based on the laser position and movement. An ability to output the display image to a monitor or projector, likely using VGA. An ability to manipulate the “paint brush” to produce different colors, and/or brush shapes. An ability to clear the image using a gesture or button “clicked” via laser.
