  • Patent number: 11474242
    Abstract: A lane stripe detecting method based on a three-dimensional LIDAR is for detecting a lane stripe of a road surface around a vehicle. A data acquisition transforming step is for obtaining a plurality of vehicle scan point coordinates. The vehicle scan point coordinates are divided into a plurality of scan lines, and each of the scan lines has a plurality of scan points. A horizontal layer lane stripe judging step is judging whether each of the scan points is a horizontal stripe point or a non-horizontal stripe point according to a threshold value of each of the scan lines. At least two of the threshold values of the scan lines are different from each other. A vertical layer lane stripe judging step is for judging whether each of the horizontal stripe points is a same lane stripe point or a different lane stripe point.

  • Patent number: 10670701
    Abstract: A dynamic road surface detecting method based on a three-dimensional sensor is provided. The three-dimensional sensor receives a plurality of laser-emitting points reflected from a road surface to generate a plurality of three-dimensional sensor scan point coordinates which is transmitted to a point cloud processing module. The point cloud processing module transforms the three-dimensional sensor scan point coordinates to a plurality of vehicle scan point coordinates according to a coordinate translation equation, and then transforms a plurality of vehicle coordinate height values of the vehicle scan point coordinates to a road surface height reference line according to a folding line fitting algorithm. An absolute difference of two scan point height values of any two adjacent scan points on each of the scan lines is analyzed to generate a discontinuous point. The point cloud processing module links the discontinuous points to form a road boundary.

  • Patent number: 7816194
    Abstract: A method of manufacturing thin film transistor is provided, in which the method of manufacturing includes a new etching process of island semiconductor. The new etching process of island semiconductor is controlled by a flow rate of etching gas and a regulation of etching power. When etching the island semiconductor, a part of gate insulation layer exposed out of the island semiconductor is etched at the same time. Consequently, the thickness of gate insulation layer over the storage capacitance electrode is reduced, the distance between the pixel electrode and the storage capacitance electrode is decreased, and the storage capacitance of pixel is increased. Finally, the width of storage capacitance electrode is reduced appropriately and the aperture ratio of product is increased.
