    Abstract: The present invention proposes an active scene mapping method based on constraint guidance and space optimization strategies, comprising a global planning stage and a local planning stage; in the global planning stage, the next exploration goal of a robot is calculated to guide the robot to explore a scene; and after the next exploration goal is determined, specific actions are generated according to the next exploration goal, the position of the robot and the constructed occupancy map in the local planning stage to drive the robot to go to a next exploration goal, and observation data is collected to update the information of the occupancy map. The present invention can effectively avoid long-distance round trips in the exploration process so that the robot can take account of information gain and movement loss in the exploration process, find a balance of exploration efficiency, and realize the improvement of active mapping efficiency.

    Abstract: A construction vehicle generates an object map to facilitate navigation. The construction vehicle captures an image of the area behind the construction vehicle, and generates a disparity image reflecting depth behind the construction vehicle. The construction vehicle generates and processes a 3D point cloud representation of the area behind the construction vehicle to identify a ground plane. The construction vehicle dynamically generates a virtual plane parallel to the ground plane based on the movement and position of the construction vehicle. After applying the virtual plane to the disparity image, the construction vehicle generates an object map identifying locations of objects greater than a threshold size and the height of the virtual plane. The construction vehicle navigates through the area behind the construction vehicle using the generated object map.

    Abstract: A semi-public blockchain maintained on one or more nodes in a map cloud platform comprises data for maintaining a global map of a predetermined geographic area. The blockchain also comprises a plurality of data records, where each data record is associated with an update to a global map. When a message associated with a map update to the global map is received, the nodes of the blockchain determine a consensus by evaluating the map update, where the evaluating comprises performing a plurality of proofs including a proof of location, a proof of iterations, a proof of physical delivery and a proof of safety. When consensus is attained and the map update is validated, a data record associated with the map update is generated and added to the blockchain with a timestamp and a link to prior data records in the blockchain.

    Abstract: This application provides a method for controlling vehicles driving as a platoon performed by an electronic device. The method includes: transmitting a first vehicle clearing message to a target in-platoon vehicle, and a second vehicle clearing message to following vehicles behind the target in-platoon vehicle, the first vehicle clearing message used for instructing the target in-platoon vehicle to leave the platoon, the second vehicle clearing message used for instructing temporary clearing of the following vehicles behind the target in-platoon vehicle; receiving a platoon joining message returned from the following vehicles behind the target in-platoon vehicle; and reorganizing the following vehicles behind the target in-platoon vehicle according to the platoon joining message to form a new vehicle platoon, the new vehicle platoon not including the target in-platoon vehicle and following vehicles having not transmitted the platoon joining message to the leading vehicle.
