Hardware is a friendly arm of smart210 development board, the project is to achieve the camera to capture images after processing opencv detected oval or round, and then in the LCD (S70) on the display, elliptical contour detection algorithm is based on opencv and least-squares fit, and added a number of conditions are not filtered oval outline in the algorithm, tested, accuracy better
