Abstract: Disclosed are a map display adjustment method and apparatus, the method including: acquiring adjustment gesture data when receiving an adjustment instruction of a map display page, the adjustment instruction being sent by a user on the map display page by a touch display screen, and the adjustment gesture data at least including an adjustment start finger position and an adjustment end finger position; analyzing the adjustment gesture data to acquire adjustment indexes, the adjustment indexes being configured to identify a position change of an adjustment gesture in a current map display adjustment process; and scaling the map display page and rotating the map display page at a first view angle and a second view angle according to the adjustment indexes, the first view angle being a view angle in a map parallel plane and the second view angle being a view angle in a map tangent plane.

Abstract: The present disclosure provides a method and an apparatus for optimizing 3D map display, which relate to the field of map data processing technologies, and mainly aim at solving the problem that the existing 3D map has a poor display effect. The method includes: acquiring map data of a working region; analyzing the map data to acquire a first region set and a second region set, where the first region set contains one or more passable regions for a robot, and the second region set contains one or more impassable regions for the robot; determining a display height corresponding to each region in the second region set respectively by using a preset height algorithm; and displaying the working region in a 3D map according to the display height. The present disclosure is mainly used for 3D map display.

Abstract: Disclosed are a dual-motor multi-gear hybrid transmission system and a vehicle. The dual-motor multi-gear hybrid transmission system includes an engine, a first motor, a second motor, a first clutch, a second clutch, a first planet row, a second planet row, a first input shaft, a second input shaft, a third input shaft and a brake assembly. The first input shaft is connected to the engine through the first clutch. The second input shaft is connected to the engine through the second clutch, and the second input shaft is sleeved outside the first input shaft. The first motor is connected to the engine. The second motor is connected to the first planet row through the third input shaft. The brake assembly is configured to brake the first planet row and/or the second planet row.

Abstract: Provided are a map drawing method, a map drawing device, a computer-readable storage medium and an electronic apparatus. The map drawing method comprises scanning a boundary of a surface medium region to generate an initialized region; merging boundary coordinates of the initialized region to obtain a merged region; dividing the merged region into a plurality of sub-regions according to a preset shape; and drawing the boundary of the surface medium region based on the sub-regions and the merged region to obtain a map of the surface medium region. The method can improve the detailedness of the drawn map of the surface medium region.

Abstract: A cleaning path acquisition method includes: generating a cleaning path of a cleaning device on the basis of a path of the cleaning device, a state mode of the cleaning device, and the amount of water consumed by the cleaning device, wherein the state modes of the cleaning device comprise one or more of a sweeping state mode, a mopping state mode, a sweeping and mopping state mode, and a sweeping and mopping idle state mode; and the cleaning path comprises one or more of a sweeping path, a mopping path, a sweeping and mopping path, and a sweeping and mopping idle path corresponding to the state modes of the cleaning device.

Abstract: A method to intercept an universal serial bus (USB) related request and to respond the intercepted request in a virtualized environment includes connecting a virtual USB peripheral controller in a virtualization software in the virtualized environment to a virtual machine in the virtualized environment. An USB data access request generated by the virtual machine may be intercept by the virtual USB peripheral controller so that the USB data access request does not reach a kernel space of the virtualization software and physical hardware resources supporting the virtualized environment. The method further includes generating a response according to the USB data access request and a process called by a firmware framework module of the virtual USB peripheral controller and transmitting generated response towards the virtual machine.
