rewrite this: Visual odometry is defined as the process of determining the position and orientation of an object by analyzing the associated camera images. In this lab the tracking camera in the visualization studio is used to take the images of the position and orientation of the object, the puck as well as a ruler with two colored dots on it. The goal of this lab is to then estimate the value of gravity on the tracking object using the tracking camera data and the ruler data to convert from pixel units to S.I. units. By analyzing the movement of the tracking object down the simulated frictionless incline, the velocity can be calculated and graphed, from which the acceleration can then be drawn as acceleration is the slope of the velocity graph. The ruler data is then used to convert the data from the tracking camera unit of pixels to the SI unit meters. All calculations also take into account the uncertainties related to them
