Abstract
A laser perception-based method for spatial positioning of an agricultural robot: erecting a laser radar with a ranging function in a positioning space, setting a three-dimensional coordinate system, and conducting scanning using the laser radar to obtain point cloud data of an object in the positioning space, where the point cloud data include an azimuth and a distance with respect to the laser radar; installing a laser receiver on the agricultural robot, receiving a laser radar signal using the laser receiver during movement, when a laser beam emitted by the laser radar irradiates the laser receiver, outputting laser signal data and elevation data from the laser receiver; conducting time-event matching on the laser signal data obtained by the laser receiver and the point cloud data scanned by the laser radar within each scanning period of the laser radar to obtain three-dimensional coordinates of a central position of the laser receiver.
