We also have a second command line argument, -buffer, which controls the maximum size of the deque of points. If the -video switch is omitted, your webcam will (attempted) to be used instead. If you want to use a video file with this example script, just pass the path to the video file to the object_movement.py script using the -video switch. Lines 11-16 handle parsing our two (optional) command line arguments.

If you don’t have imutils installed/upgraded yet, let pip take care of the installation process: $ pip install -upgrade imutils If you’re a follower of this blog, you likely already have this package installed. We’ll also need imutils, by collection of OpenCV and Python convenience functions. We need Python’s built in deque datatype to efficiently store the past N points the object has been detected and tracked at. We start off by importing our necessary packages on Lines 2-8. Help="path to the (optional) video file")Īp.add_argument("-b", "-buffer", type=int, default=32, # construct the argument parse and parse the arguments Open up a new file, name it object_movement.py, and we’ll get to work: # import the necessary packages

If you want more detail for a given code snippet, please refer to the original blog post on ball tracking.
Note: The code for this post is heavily based on last’s weeks tutorial on ball tracking with OpenCV, so because of this I’ll be shortening up a few code reviews. Looking for the source code to this post? Jump Right To The Downloads Section OpenCV Track Object Movement

We won’t be learning how to build the next generation, groundbreaking video game controller - but I will show you how to track object movement in images, allowing you to determine the direction an object is moving: This week’s blog post is an extension to last week’s tutorial on ball tracking with OpenCV. Of course, then there is the XBox Kinect (one of the largest modern day computer vision success stories, especially within the gaming area) that required no extra remote or wand - using a stereo camera and a regression forest for pose classification, the Kinect allowed you to become the controller. Over on the PlayStation side, we had PlayStation Move, essentially a wand with both (1) an internal motion sensors, (2) and an external motion tracking component via a webcam hooked up to the PlayStation 3 itself. While it a bit gimmicky, the Wii Remote was a major paradigm shift in user/game interaction. It probably goes without saying that Final Fantasy VII is my favorite RPG of all time - and it feels absolutely awesome to be playing it again.īut as I sat on my couch a couple nights ago, sipping a seasonal Sam Adams Octoberfest while entertaining my old friends Cloud, Tifa, Barret, and the rest of the gang, it got me thinking: “Not only have video games evolved dramatically over the past 10 years, but the controllers have as well. I spent so much time inside this alternate world that I completed nearly every single side quest. As a kid in late middle school/early high school, I logged 70+ hours playing through this heartbreaking, inspirational, absolute masterpiece of an RPG.Īs a kid in middle school (when I had a lot more free time), this game was almost like a security blanket, a best friend, a make-believe world encoded in 1’s in 0’s where I could escape to, far away from the daily teenage angst, anxiety, and apprehension. This past Saturday, I was caught in the grips of childhood nostalgia, so I busted out my PlayStation 1 and my original copy of Final Fantasy VII.
