针对多椭圆检测问题提出了一种快速随机检测算法。该算法利用在图像中随机采样到的一个边缘点和 局部搜索到的两个边缘点以及这三个点的邻域信息确定候选椭圆,再将候选椭圆变换为对应圆,通过确认真圆来确 认真椭圆。在确定候选椭圆时,最大限度地减少随机采样点数‰ 剔除更多的非椭圆点,降低了无效采样,减少了无效 计算。数值实验结果表明:该算法具有良好的鲁棒性,其检测速度比同类算法快(Ellipse detection problem for many a fast random detection algorithm. The algorithm uses random sampling in the image of an edge point and the local search to the two edge points, as well as the three-point neighborhood information to determine the candidate ellipse, and then transformed into the corresponding elliptical candidate won, through the identification of real yen to confirm really elliptical. In determining when a candidate ellipse, to minimize random sampling points ‰ remove more non-oval points, reducing invalid sampling, to reduce the calculation invalid. Numerical experimental results show that: the algorithm has good robustness, and its detection faster than similar algorithms quickly)

说明：  使用抖动创建图像。使用抖动得到的图像看上去有更多的颜色数；不适用抖动得到的图像看上去颜色数少，大门空间分辨率要高些。(Creating images using dithering. Jitter by using the image appears to have more number of colors not apply to jitter resulting image looks small number of colors, the door to higher spatial resolution.)

说明：  通过仿真生成加速度计、陀螺仪以及漂移数据，用于仿真验证应用(Accelerometer, gyroscope and drift data are generated by simulation, which are used for simulation verification application)
