A camera calibration technique based on OpenCV
The 3rd International Conference on Information Sciences and Interaction Sciences, 2010Camera calibration is very improtant in 3D computer vision systems. In this paper, the camera model in OpenCV (open source computer vision library) is discussed, the non-linear distortion of the tangential and radial distortion aberration are considered.

We’ve come a long way since the first chapters introducing the Raspberry Pi. At this point, you have learned about the Pi and the Arduino. You’ve learned how to program both boards. You’ve worked with sensors and motors. You’ve built your robot and programmed it to roam around and to follow a line.

A Camera Calibration Method Based On OpenCV
Proceedings of the 2019 4th International Conference on Intelligent Information Processing, 2019Automobile four-wheel positioning refers to the accurate measurement of a specific set of angles of the car wheel. The accuracy of the four-wheel positioning is directly related to the overall performance of the car. Camera calibration as the first step in four-wheel positioning measurement and three-dimensional modeling is of great significance for ...

OpenCV Performance Measurements on Mobile Devices
Proceedings of International Conference on Multimedia Retrieval, 2014Mobile devices like smartphones and tablets are becoming increasingly capable in terms of processing power. Although they are already used in computer vision, no comparable measurement experiments of the popular OpenCV framework have been made yet. We try to fill this gap by evaluating the performance of a set of typical OpenCV operations, on mobile ...

A Calibration Method Based on OpenCV
2011 3rd International Workshop on Intelligent Systems and Applications, 2011To satisfy the demand of the real-time computer vision system, a method of camera calibration was analysed. According to the camera model from OpenCV(Intel Open Source Computer Vision Library), with radial aberration and tangential aberration considered, Zhang's arithmetic of camera calibration was applied.
