Eyeball and blink controlled firing system for military tank using LabVIEW

Presently, most of the modern military tanks require 4 members to operate. In this paper, we try to reduce the number of persons to operate the tank by one and increase the ease of targeting enemies. This is achieved by controlling the firing systems of the tank with the help of eyeball movement and blink. Image of the eye is captured using a camera, which is placed in front of the eye, and centroid of the iris is found to track the eye. The turret's vertical as well as horizontal position is controlled using the eyeball movement and the gun can be fired with the help of blink. It is possible to switch between the main gun and the machine gun with ease. The machine gun is also controlled in a similar manner. Thus, our system allows the driver to control the tank as well as the firing system thereby reducing number of people to control the tank.
