PRIOR INFORMED POSE AND SCALE ESTIMATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17931238 titled 'PRIOR INFORMED POSE AND SCALE ESTIMATION
Simplified Explanation
The patent application describes a method for estimating the scale and pose of a camera system based on camera data and a scale prior parameter. The method involves calculating a cost function for a similarity transformation, where the cost is influenced by the scale prior parameter. If the cost function is below a threshold, the estimated scale and pose of the camera system are output.

Original Abstract Submitted
A scale and pose estimation method for a camera system is disclosed. Camera data for a scene acquired by the camera system is received. A scale prior parameter characterizing scale of the camera system is received. A cost of a cost function is calculated for a similarity transformation. The cost of the cost function is influenced at least by the scale prior parameter. Based at least on the cost function being less than a threshold cost, an estimated scale and pose of the camera system is output based on the similarity transformation.
