Camera calibration and 3D reconstruction – interactive camera calibration application OpenCV v4.8.0

Previous tutorial: Real-time pose estimation of textured objects Original author Vladislav Sovrasov Compatibility OpenCV >= 3.1 According to the classic calibration technique, the user must first collect all data and then run the cv::calibrateCamera function to obtain the camera parameters. If the average reprojection error is large, or the estimated parameters appear to be wrong, […]

A guide on how to create interactive and animated graphics with HTML5 Canvas and JavaScript

Article directory Preface Effect demonstration Code explanation Complete code end Foreword This article explains how to create an interactive bubble effect using HTML5’s Canvas and JavaScript. By moving with the mouse or touch, you can create flowing bubble trajectories on the canvas. This effect takes advantage of the spring effect between points, allowing the bubbles […]

(Multimodal Medical) CephGPT-4: Interactive multimodal cephalometric and diagnostic system using visual large language model

Paper address Abstract In this paper, we propose a novel multimodal cephalometric analysis and diagnostic dialogue model. First, a multimodal orthodontic medical data set is constructed, including cephalometric images and doctor-patient dialogue data, and U-net is used to automatically analyze cephalometric signs and generate a diagnostic report. Then, the cephalometric data set and the generated […]
