PythonComputerVision-6-CameraCalibration 使用Python及OpenCV实现相机参数标定 一.针孔相机模型原理: 在相机模型中,针孔相机是相对简单而常用的模型。简单的说,针孔相机模型就是把相机简化成小孔成像,如图下图,f标注的距离是焦距。 简单的相机标定原理: 相机标定(Camera Calibration)可以理解为从普通世界坐标系变换到图像...

control the camera, along with a number of AI algorithms to detect objects, recognize faces and recognize gestures. These are implemented asTensorflow Litemodels. In our case, we’ll use Vilib to take pictures, then we’ll useOpenCV, the open source computer vision library to compare the ...
