GMU:Custom Setup to track People using a Camera on the Ceiling

Introduction

It’s a tutorial about using a camera connected with cv.jit. to grab the x, y coordinates of people on the platform.

cv.jit is a collection of max/msp/jitter tools for computer vision applications. The goals of this project are to provide externals and abstractions to assist users in tasks such as image segmentation, shape and gesture recognition, motion tracking, etc. as well as to provide educational tools that outline the basics of computer vision techniques.

Part 1 Install cv.jit library

Firstly, you need to download the cv.jit. The latest version of cv.jit is 1.8 and can be used with 64-bit versions of Max. Find instructions to check it here: http://jmpelletier.com/cvjit/

Part 2 Set up

Notice: If you use the ladder, please make sure to put several layers of cardboard below it, to prevent damage to the dance carpet. Please make sure that everything is securely fixed.

In this tutorial, the camera is not a full view camera and the height of space is limited, so the view seems too narrow. This tutorial shows how to get the x, y coordinates of one person on the stage as an example.

Set up the camera on the ceiling.
