  • PATH PLANNING METHOD AND DEVICE, ROBOT AND STORAGE MEDIUM
    Publication number: 20230273031
    Abstract: Disclosed are a path planning method and a device, a robot and a storage medium. The method includes: grading a traversable region between a starting point and an end point in a grid map, and determining cost values corresponding to regions of each level; traversing the traversable region from the starting point based on the cost values of the regions of each level, and determining a plurality of target nodes conforming to a minimum value of a preset function; and determining a target path of a robot based on the plurality of target nodes.

  • Portable device positioning data processing method and apparatus, device, and storage medium
    Patent number: 11574417
    Abstract: A method for processing positioning data of a mobile device is provided, comprising: acquiring a first original point set and a target point set by measuring an object surface with the mobile device; extracting feature points from the first original point set to obtain an original key point set; extracting feature points from the target point set to obtain a target key point set; performing a first registration operation on the original key point set and the target key point set to obtain a first model transformation parameter; transforming the first original point set by the first model transformation parameter to obtain a second original point set; performing a second registration operation on the second original point set and the target point set to obtain a second model transformation parameter; and acquiring third model transformation parameter based on the first model transformation parameter and the second model transformation parameter.
