Motor and Camera Control

Well, I finally made a project during my research that satisfied my desire to create something every day. I also think I can share my pretty basic program that I wrote in LabView. The idea was that I wanted to take images using an Imaging Source camera, but I needed a sequence of images, the timestamps, and how they related to the position of my stepper motor.

The imaging source website gave a nice guide into how to setup LabView to grab individual images, so I expanded that using a signal property to grab an image each time my loop progressed. I also wanted to start my motor at time zero, so I implemented a simple transistor as a switch to my timing chip to give it the start at zero. I also read in the changes in the digital signal, but it is not clear if that is correctly counting the position due to timing lapses with the camera read in.

Regardless, by assuming the motor has a constant velocity, and knowing that velocity, the camera can be coordinated to the angle of the motor and the position of my end-effector. Success!
