| Abstract: | To meet the requirement of panoramic monitoring projects,a fisheye lens was used as the imaging unit of the image sensor for imaging.A new method was brought in estimating the circular area of the fisheye image.Sphere perspective projection and cylinder expanse model were used to solve the problem of distortion.At the same time,virtual PTZ control was realized.According to the test,the software has a strong robustness in kinds of monitoring situation,it can meet the requirement of full-field monitoring with... |
