As said and shown before, the P3P equations are not easy to solve. As an example, the solution provided in the opencv library does not compute fully satisfactory results. This article has the objective to summarize the best strategy to implement the P3P approach.
Projective geometry is an important subject if you wish to create computer vision applications.
In this post, is presented a youtube™ video that aims to show the differences between the P3P (Perspective-Three-Point) principle such as implemented in opencv and my own implementation. Continue reading →
