  • Patent number: 11926339
    Abstract: A method and a system for constructing a driving coordinate system for use in the field of smart transport. The method for constructing a driving coordinate system comprises: determining the road boundary line on one side of the road on which a current vehicle is situated as a reference line for constructing a driving coordinate system; in a vehicle coordinate system, determining the reference line point having the smallest distance between the reference line and the current vehicle position as an origin point OF of the driving coordinate system; on the basis of the origin point OF, determining the road guiding line direction as the XF axis of the driving coordinate system and determining the direction relative to the road guiding line direction according to the left-hand rule as the YF axis of the driving coordinate system; and, on the basis of the origin point OF, the XF axis, and the YF axis, forming a corresponding driving coordinate system.

  • Patent number: 11928870
    Abstract: A method and apparatus used for extracting a feature point of an environmental target, which relate to the field of vehicles. The method comprises: acquiring the position of each corner point of an environmental target; and determining a feature point of the environmental target according to the position of each corner point of the environmental target. Thus, the problem wherein target identification is not precise may be solved, which is particularly suitable for the identification of a large target.

  • Patent number: 9195082
    Abstract: A break separation apparatus and method are provided. The apparatus comprises a vibration stage for holding at least one liquid crystal panel to be separated and vibrating the liquid crystal panel so that glass substrate of the liquid crystal panel breaks along a cutting groove. According to the apparatus and method, the cutting grooves cut on the glass substrate are substantially extended in thickness direction of the glass substrate by vibration method so as to achieve separation, which can be readily controlled and avoid contamination and damage to the liquid crystal panel.
