Checkerboard Tracker for Camera Calibration
The checkerboard extraction process is an important pre-preprocessing step in camera calibration. This project attempts to implement the checkerboard extraction processes using methods learned from EE368. This includes the isolation of the checkerboard using morphological operations. The benefit of the approach is that it is efficient since morphological operations can be implemented efficientl...
متن کاملA New Method for Encryption of Color Images based on Combination of Chaotic Systems
This paper presents a new method for encryption of color images based on a combination of chaotic systems, which makes the image encryption more efficient and robust. The proposed algorithm generated three series of data, ranged between 0 and 255, using a chaotic Chen system. Another Chen system was then started with different initial values, which were converted to three series of numbers from...
متن کاملROCHADE: Robust Checkerboard Advanced Detection for Camera Calibration
We present a new checkerboard detection algorithm which is able to detect checkerboards at extreme poses, or checkerboards which are highly distorted due to lens distortion even on low-resolution images. On the detected pattern we apply a surface fitting based subpixel refinement specifically tailored for checkerboard X-junctions. Finally, we investigate how the accuracy of a checkerboard detec...
متن کاملA Novel Camera Calibration Method Based on Polar Coordinate
A novel calibration method based on polar coordinate is proposed. The world coordinates are expressed in the form of polar coordinates, which are converted to world coordinates in the calibration process. In the beginning, the calibration points are obtained in polar coordinates. By transformation between polar coordinates and rectangular coordinates, the points turn into form of rectangular co...
متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
