Abstract: A method is provided for a travelling vehicle to detect lane lines. A front camera module captures frames of front image of the vehicle, a rear camera module captures frames of rear image of the vehicle, and a speed sensor module senses speed trajectory of the vehicle. In the method, the frames of front image, the frames of rear image and the sensed speed trajectory are used to obtain pairs of matched front and rear images, and to determine reliability of a lane line feature detected in a current front image or a current rear image based on the pairs of matched front and rear images, and the lane line feature detected from the current front image or the current rear image is outputted upon determining that the currently detected lane line feature is reliable.

Abstract: A method for measuring periodic motion of an object includes the steps of: after receiving an axial acceleration and a radial acceleration, calculating a first included angle between a composite acceleration, which is a sum of the axial acceleration and the radial acceleration, and one of an axial direction and a radial direction, and a second included angle between the composite acceleration and the other one of the axial direction and the radial direction; and based on a magnitude relation between the second included angle and the first included angle, controlling a periodic motion counter to increment a motion counter value which is associated with a number of times the periodic motion of the object has occurred.
