  • Publication number: 20230071794
    Abstract: A method for constructing a lane level map using a three-dimensional point cloud map is provided. According to the method, during scan matching for estimating the location of a vehicle in the process of automatically constructing a 3D high-definition map, the amount of computation is reduced by reducing the size of a target 3D map. Thereby the method is performed fast and accurate position estimation. In addition, even if the position estimation by scan matching fails, more robust position estimation is possible by estimating the location of the vehicle using LiDAR odometry performed in parallel. The method builds and merges a precise lane map with a pre-built 3D point cloud map using such robust localization to build a more precise 3D precise map and a lane node-link map. By using these three-dimensional precise maps and maps that generate node-links in lanes, a more effective route planning algorithm that can be provided.

  • Publication number: 20230005651
    Abstract: A nano spintronic device for using the spin current of a ferromagnetic material and the spin current of a heavy metal channel. The device includes a lower channel layer, a free layer, a pinned layer, an insulating film layer, and an upper channel layer. When current flows upon application of power, electrons are divided into +y-polarized spins and ?y-polarized spins in the lower channel layer, thereby generating torque in the free layer. The torque switches the magnetization direction of the free layer to an +y-axis direction or an ?y-axis direction so that the free layer stores magnetization information according to the magnetization direction. When current flows in the upper channel layer, the current flows into the pinned layer so that electrons in the pinned layer are divided into +y-polarized spins and ?y-polarized spins. The insulating layer insulates the free layer and the pinned layer from each other.
