Abstract: A vehicle-mounted lidar external parameter joint calibration method and system, a medium and a device. Said calibration method comprises: respectively acquiring point cloud data of the reference radar and point cloud data of a radar to be calibrated, obtain a corresponding plane A point cloud and a corresponding plane B point cloud, and calibrating a rotation matrix; rotating the plane A point cloud corresponding to said radar by means of the rotation matrix, and obtaining a z component of a translation matrix on the basis of the rotated plane A point cloud and the plane A point cloud corresponding to the reference radar; and obtaining a calibration column point cloud from the point cloud data of the reference radar, and obtaining x and y components of the translation matrix on the basis of the calibration column point cloud and the rotated plane A point cloud corresponding to said radar.

Abstract: An umnanned vehicle with a separable functional module includes a functional module, a chassis for supporting the functional module, and a vehicle head mounted on the chassis, a locking mechanism connected to the functional module is disposed on the chassis or the vehicle head, and the functional module is combined with or separated from the chassis or the vehicle head through locking or unlocking of the locking mechanism.

Abstract: A unitized space management method for separating transportation rights and usage rights, comprising: each unitized space is a standard goods container, and an electronic tag is for marking the usage rights of each unitized space container; a logistics vehicle is the transport carrier to implement the logistical transport process of the unitized space; during the process, the unitized space is located on transport vehicle and is in a locked state under an owner control; after the logistics vehicle transports the unitized space to a destination, the unitized space may or may not be separated from the logistics vehicle. Under the owner control, comparison verification of the electronic tag is used to implement usage and exercise the usage rights of the unitized space, for example picking up or placing items stored in the unitized space. The method has advantages of higher efficiency, a wider range of application, and better security.

Abstract: A grid cabinet with variable spaces includes a cabinet body and a control part. The cabinet body is provided with two or more accommodating cavities, each of which is provided with at least one door and a door locking part. A separator is disposed between every adjacent accommodating cavities, the adjacent accommodating cavities are separated into respective independent spaces by the separators, and a separator locking part for fixing and locking the separator is provided in each accommodating cavity. Under control of the control part, the door locking parts of two or more adjacent accommodating cavities are opened synchronously, the separator locking parts are loosened, and the separators are operated so that the two or more adjacent accommodating cavities are communicated.
