android-object-distance

Android sample app which provides distance of an object from the camera; using contour based image recognition through OpenCV. This project is avilable on google play store as an example.

  • Place an object with a highlighted boundry in front of your phone.
  • Take a picture and enter its initial ditance and length of its perimeter, all in centimeters.
  • Now move the phone some distance away and take the picture again.
  • A distance, from phone to object, will be displayed.
  • Approx. error ~2cm.

Tested on Nexus 5.
