GoPro Hero3 Black

Description

The GoPro Hero3 Black is a tiny camera with a lot of nice features, including a moderately high maximum frame rate (240 fps) and the ability to control the camera from a smartphone.

Limitations

Unfortunately, the Hero3 has a big disadvantage for video analysis: The lens is extremely wide angle, so there is a lot of radial distortion. Even when the camera is set for a narrow field of view, there is very clear curvature of "straight" lines that are off-center. The newer Hero3+ is supposed to have less distortion, but we do not have one to test. A Hero3 should work well for one-dimensional motion that goes through the center of the image, but expect systematic errors in 2D or off-center 1D motion.
