Golf Project Cameras

Table of Contents

Objective

To meet the goals of the project, a high speed camera was used to capture the golf ball at high speeds. It was important to capture the golf ball at high speeds and capture a number of frames to get data that could be used. An average dSLR would not be able to capture the camera at high speeds and would capture a blur of the ball.

The video footage collected would later be used for the tracking software. Since the cameras selected did not have a virtual connection with the computer, the collecting and exporting had to be two different tasks.

More information on the specifics of a high speed camera can be found on the High Speed Camera page.

Sony DSC-RX100M7

An example of a high speed camera is the Sony DSC-RX100M7 which was used for the golf project. The fastest shutter speed for this camera is 1/32,000 of a second [1]. As well, it has a wide aperture of F2.8 allowing for more light to enter. Other brands and models may offer different speeds and technical features, such as different aperture size and fast shutter speed.

The challenge with this camera was the frame speeds. The fastest it could go is 120 frames per second.

Krontech Chronos Camera

This camera was able to take photos at a frame speed of 1,000 frames per second which is considerably faster.

Comparison of Two Cameras

In the end, both cameras offer different benefits and disadvantages for the golf project. A summary table of the two can be seen below:

	Sony High Speed Camera	Krontech High Speed Camera
Benefits	Zoom offers wider and more zoomed in capabilities to capture more of the golf ball trajectory	Collects more frames in a matter of a seconds: up to 10,000 fps
Disadvantages

Feature	Sony High Speed Camera	Krontech High Speed Camera
Frame Speed	Collects up to 120 frames per second	· Collects more frames in a matter of a seconds: up to 10,000 fps
Shutter Speed	· 32,000 of a second	· Up to 100,000 of a second
Range of View	· With zoom lens, can adjust easily. Zoom offers wider and more zoomed in capabilities to capture more of the golf ball trajectory	· It is a prime lens with no zoom capabilities.
Battery	·	Needs to be powered most times, as the power is lost quick
	Video saves right away once it is taken. It takes a few seconds before the next video can be taken	Slow save times (40 fps)
Download Times	Both cameras can have the SD cards removed and download
