- W2348800399 abstract "When shooting video,due to the limitations of the shooting location,direction and other factors,the captured image will often appear trapezoidal distortion.By analyzing the digital image trapezoidal distortion mechanism and taking into account the complexity of the physical environment proposed a call in VC + + environment OpenCV library functions to achieve real-time correction video image trapezoidal distortion correction effect.Firstly,the use of artificial calibration edge contour extraction trapezoidal distortion image;outline the coordinates of the vertices,and then calculate the corresponding vertex coordinates of each vertex in the corrected image,distortion correction matrix obtained by the vertex coordinates.Finally,the distorted image correction.Experimental results show that this method can quickly and efficiently to achieve real-time correction,and has strong robustness." @default.
