We describe a new tracking and predicting scheme applied to a lab-made ping pong robot. The robot has a monocular vision system comprised of a camera and a light. We propose an optimized strategy to calibrate the light center using the least square method. An ellipse fitting method is used to precisely locate the center of ball and shadow on the captured image. After the triangulation of the ball...
A method for fatalness evaluation of flight safety hidden danger, based on support vector machine (SVM), is proposed. And the corresponding model, which makes the basic evaluation factors of flight safety hidden danger fatalness as input node and evaluation results as output node, is established. Then the safety situation of a regiment of China Air Force is evaluated. The application result shows...
Wavelet neural network (WNN) trained by unscented Kalman filter (UKF) has many merits of fast convergent rate and small prediction error without computing the Jacobian matrix. Based on this, an improved UKF is introduced into the parameters estimation for WNN. The algorithm uses an unscented transform (UT) based on minimal skew simplex Sigma point sampling strategy in the frame of Kalman filter, which...
