Provided are a measuring method and apparatus for a damaged part of a vehicle includes: acquiring an image to be processed of a vehicle; acquiring the damaged part of the vehicle in the image to be processed according to the image to be processed; acquiring first position information of key points in the image to be processed according to the image to be processed; determining a transformation relation between the image to be processed and a first fitting plane according to the key points included in the image to be processed and the first position information, where the first fitting plane is a fitting plane determined according to the key points included in the image to be processed on the 3D model; acquiring a projection area of the damaged part in the first fitting plane according to the transformation relation; and measuring the projection area to acquire a measuring result.

Measuring method and apparatus for damaged part of vehicle

A method, an apparatus and a system for information transmission are provided. The method includes the following steps. A second user equipment receives update information issued by a wireless access point (AP). The second user equipment is located within a coverage area of the wireless AP. After detecting that the second user equipment has the update information, a first user equipment establishes a connection with the second user equipment and obtains the update information from the second user equipment. A wireless AP of the first user equipment is located outside the coverage area of the wireless AP. In the present invention, the user equipment can update the information without additionally increasing the transmit powers of the wireless AP and the user equipment when located outside the coverage area of the wireless AP, and thus the interference to other equipments is not increased.

A method for adjusting data rate in a network is disclosed. In the method, when a device is added to the network, a data rate controlling parameter is configured, and when there is a new service or the requirements of a service have been changed, the data rate will be adjusted by modifying the data rate controlling parameter of a source device and/or a transfer device. Therefore, the fairness among these devices would be guaranteed, and the congestion over the network would be mitigated. The present invention also discloses a wireless communication system, a data rate adjusting device, and a topologic server.
