廣角鏡頭因為其提供較寬廣的視野特性，已經被運用在許多領域上面，例如：無人空拍機、汽車倒退顯示器、醫學用內視鏡等等，但是廣角鏡頭焦距過於短，會造成所謂桶狀扭曲(barrel distortion)的效果影響影像的資訊，因此本論文實作一種演算法來消除桶狀扭曲影響並保留影像廣角的效果。
現今有關於桶狀扭曲轉正的硬體架構主要使用長度多項式模型，多項式模型的特性是假定角度不變的情況下，利用相機參數修正各像素點與影像中心的距離，使得影像會有消除桶狀扭曲的效果。因此相機參數在此校正模型扮演很重要的地位，但是求解過程過於繁瑣複雜，尋找參數也會花費大量的時間。
本論文提出一種即時管線化的桶狀扭曲轉正VLSI架構，藉由修正像素跟影像中心的夾角，來修正每個像素的位置，此方法的參數可以使用校正板來求得，較現今硬體架構都方便取得許多。電路架構使用TSMC 0.90nm標準元件庫來進行合成。合成結果顯示，面積為536721，工作時脈可達到100MHz。

Wide-angle lenses have been used in many fields because they provide a wider field of view, such as: unmanned aerial cameras, car reversing displays, etc. But the focal length of the wide-angle lens is too short, which will cause the effect of barrel distortion. So this paper implements an algorithm to eliminate the effect of barrel distortion and retain the effect of the wide angle of the image.
Nowadays, the hardware architecture for barrel distortion correction mainly uses the length polynomial model. The characteristic of the polynomial model is applied camera parameters to correct the distance between each pixel and the image center. Under the assumption that the angle is unchanged, the image will eliminate the barrel distortion effort. Therefore, the camera parameters play an important role in the calibration model, but the solution process is so complicated that it takes a lot of time to find the parameters.
This paper proposes a real-time pipelined barrel distortion correction VLSI architecture, which corrects the position of each pixel by correcting the angle between the pixel and the center of the image. The parameters of this method can be obtained using a calibration board, which is more convenient than the current hardware architecture. The circuit architecture is synthesized using TSMC 0.90nm standard component library. The synthesis result shows that the clock frequency can reach 100MHz.
