Efficient camera self-calibration method based on the absolute dual quadric.

Visual measurement technology has been widely used in fields such as industrial production or measurement and monitoring. Camera calibration is a very important link of visual measurement, because it directly determines the accuracy and precision of visual measurement. It often does not need extremely high-precision measurement but simple, rapid, effective measurement in many engineering surveys. Therefore, the camera self-calibration technique is really needed. The advantages of camera self-calibration are that it does not need any calibration target or complex mechanical structure that is used to control the camera's motion. In this paper, we propose an efficient camera self-calibration method based on the abstract quadric that is simple for calculation and has good robustness.
