    摘要: The present invention relates to the field of intelligent driving. Disclosed is a method for detecting the position relation between a vehicle and a lane line. The method for detecting the position relation between a vehicle and a lane line comprises: obtaining a vehicle model, the vehicle model being represented by a plurality of first coordinates in a world coordinate system; obtaining a lane line image, the lane line image being captured by a camera disposed on a vehicle; obtaining a calibration parameter of the camera; determining, according to the lane line image and the calibration parameter, a first line segment of a lane line mapped into the world coordinate system; and determining the position relation between the lane line and the vehicle according to the position relation between the first line segment and the plurality of first coordinates in the world coordinate system. According to the detection method, the position relation between the lane line and the vehicle can be determined without using a positioning system, so that the construction cost of intelligent driving is reduced.

    摘要: The present disclosure discloses a method and device for straight line detection and image processing. The straight line detection method includes: dividing a horizontal axis and a vertical axis of a straight line parameter space equally, so as to divide the straight line parameter space into a plurality of parameter areas; voting for the plurality of parameter areas utilizing a coordinate of each sample pixel to obtain a vote amount of each of the parameter areas; extracting a straight line parameter and the vote amount of each of the parameter areas having the vote amount larger than a voting threshold, and grouping the straight line parameters into a group; and weighting and averaging the straight line parameter of each group and the vote amount respectively to obtain the straight line parameter of a detected straight line. The present disclosure also discloses a robot and a numerical control machine.
