Make a Rangefinder with Raspberry Pi #piday #raspberrypi @Raspberry_Pi
From Kevin Le Brun on Instructables:
I am currently planning some interior work for next Spring but as I just acquired an old house I don’t have any house plan. I started to measure wall to wall distances using a ruler but it is slow and error prone. I thought about buying a rangefinder to ease the process but then I found an old article about building its own rangefinder using a laser and a camera. As it turns out, I have those components in my workshop.
The project is based on this article: https://sites.google.com/site/todddanko/home/webcam_laser_ranger
The only difference is that I will be building the rangefinder using a Raspberry Pi Zero W, a LCD, and the Raspberry Pi Camera module. I will also use OpenCV to track the laser.
