In the Google Play store there is an app titled Smart Measure that can be used to measure the height and width of an object. I would like to integrate this functionality into a survey app I am developing.
Firstly I have done a test or two with this app and it seems accurate enough. Does anyone have any opinions on the possible accuracy of this technique used by the app to determine the height and width?
How would I go about using the motion and position sensors to determine height and width of an object about 10 meters away? The trigonometry side of things I can handle, I just need an approach that will assure accuracy of at least 1 meter.
Is there any open source library that can be used? I know this is an open ended question, but was not sure were else to ask this question. Any knowledge or help would be greatly appreciated.
