A Vision Based Optical Measurement Technique With Augmented Reality Concepts

In this paper, we present the implementation of an application of augmented reality which makes it possible to measure objects in a scene captured using cameras. The implementation is based on a standard planar (Pattern) introduced into the scene. Initially, the detection and the follow-up of the pattern make it possible to use the last to calibrate the camera and to extract its parameters. This allows the passage between the different references (scene, camera, and image) and gives us the possibility of measuring existing objects in the acquired scene. Finally, some tests are presented to prove the validity and to evaluate our method.
