In image engineering practice, a common misconception is viewing "Geometric Calibration" purely as a software post-processing task. Many believe that once the hardware team assembles the camera and ...

OpenCV 5.0 released today as a major update to this widely-used, open-source computer vision (CV) library. The OpenCV library is widely-used for ral-time computer vision needs and machine learning ...

I built this project to demonstrate working knowledge of OpenCV applied to a real-world photogrammetric problem. Rather than running the standard checkerboard calibration tutorial, I reimplemented a ...

A low-cost vision-based anti-sleep alarm system that detects driver drowsiness using OpenCV and alerts via Arduino-controlled buzzer and LED Road accidents caused by driver fatigue and microsleep are ...

OpenCV 4.13 is out this New Year's Eve in providing the latest open-source computer vision (CV) capabilities. OpenCV 4.13 brings a wide variety of enhancements to this widely-used computer vision ...

Abstract: The Gauss-Markov theorem states that achieving an optimal solution requires homoscedasticity of error terms. However, during camera calibration, target ...

In this tutorial, we build an Advanced OCR AI Agent in Google Colab using EasyOCR, OpenCV, and Pillow, running fully offline with GPU acceleration. The agent includes a preprocessing pipeline with ...

Abstract: This research addresses the challenge of camera calibration and distortion parameter prediction from a single image using deep learning models. The main contributions of this work are: (1) ...

Camera calibration is the process of estimating the parameters that define the optical and geometric characteristics of a camera in order to relate three-dimensional world points to their ...
