This app is meant to measure relatively small objects at a distance of at most a few meters. The app assumes the two objects being dimensioned are at approximately the same depth.
Given a rectangular reference object like a sheet of paper, the app can correct for perspective distortion.
Important: This app requires the OpenCV Manager, which you can download from the Play Store.
