I completed a camera measurement app that makes measurements based on a known measurement (e.g. height in our case). But it was around 2-3 cms off. One solution we had to improve accuracy was to do calibration of the device camera.. but then we would have to calibrate for all the devices in the market. Long story short, we could proceed with that project.
If you have any approach in mind, we will be able to work on it as we have worked on this before. Incidentally, we also were taking mTaylor as reference. Thats were we got the idea of referencing the known height of the person. But I think mTaylor has some human intervention involved.
Do talk to me to explore possibilities. We can discuss pricing as well once the specs are clearer. Thanks.
