Question Asked:

What would be a cost-effective setup to sense a soccer ball's accuracy and speed? We are building a soccer simulation lab in Northern VA and would like to speak with someone about this engineering challenge as we fit the facility.

Sounds like an interesting project. There are a number of items that you need to consider, and you need to find out which parameter is going to be you're limiting factor. My details are attached. Send me an email, and we can arrange a call to discuss in the new year.

Isaiah, Accuracy of a shot to a target such as a bulls-eye target? Accuracy of a pass during open play? Speed of the ball during open play or speed of a single shot? Speed may be much more cost effective on its own using microphones instead of vision. 1 mic near the shooter to detect the moment of the kick and another mic at the target to detect the time of contact then simply rate = distance / time between the two sound events. Systems to measure accuracy would depend on what you envision the output to look like. Are you thinking a raw score like 94% for attempting to hit a fixed target or something more like a scatter plot showing the reproducibility of a shooting or passing distribution? If you have a fast enough vision system to track the path of the shot then you may be able to get rid of the microphones and get speed off the same system that tracks accuracy. It all depends on what you want the output to look like.
