Single-shot camera position estimation by crossed grating imaging
What's it about?
Many applications in image processing and optical metrology depend critically on the position of a camera to a reference plane. Moreover, in real-time applications such as visual control of robots and augmented reality guiding, the position of the camera is required in real-time.
Why is it important?
This paper proposes a simple method to estimate the position of a camera device by using a crossed grating in the reference plane. The proposed method is computationally efficient and highly appropriate to be used in dynamic measurement systems.
