Develop a 3D positioning system
Use a single camera

Summary

How do you create a 3D positioning system that determines an object’s location in three dimensions using a single camera? By moving the camera relative to the object, combining multiple images to determine its location.

The challenges

Creating a 3D positioning system consisting of a single camera without the possibility of additional sensors is quite a challenge. Especially when movement could be controlled reliably but the initial and final position had to be validated to accommodate for component tolerances.

Challenge Overview

Accurate 3D positioning generally needs at least two cameras, or a range of sensors.
This system could only handle a single camera.

The solution

By adding a colour-coded background behind the object, the angle between the camera and the background could be determined. This allowed the position to be detected accurately in two dimensions. By rotating the object relative to the camera and capturing multiple images at different angles, it was possible to determine the position in three dimensions, while improving accuracy at the same time.

Solution Overview

Determined 3D positions by moving and rotating the camera along different axes.
Allowed the different images to be correlated with simple markers.
Accurately determined the 3D position without device modifications.

Let's hear it from some of our clients:

Software had to built from scratch for an ophthalmic medical device. Initially, optimizing the image processing algorithms, calibration software and the maps and parameters in the UI created a system with a high entropy. Etosis has been instrumental in overcoming these complexities and delivering a stable device with good performance.
