Volume Calculation using Image Processing and Distance Sensor !
I started my internship at Lambda Theta on 16th May and I was working on a project to calculate volume of a box. We decided to use the image processing for the calculation of 2 dimensions while the third dimension was to be calculated using distance sensor.

I have previously posted about about the use of Raspberry Pi 3 for this project and image processing to be done using OpenCV with Python.
I must admit that used Python over an year ago and this was my first time with OpenCV, however, tutorials at PyImageSearch made my task much easier. There is already a tutorial on PyImageSearch on how to measure the size of an object in an image. The tutorial uses an object of a known size as a reference to calculate the size of an object.
However, in our case the problem was that we couldn't use a reference object because the height of the box would vary every time. So we used a distance sensor to calculate the height of the object. And then this height was used as a reference to calculate the width and length of the box. I can't give out the exact details on how we achieved this but if you really want to know contact me personally and I might be able to help you a little.
