INFORMATION SENDING METHOD, INFORMATION RECEIVING METHOD, RELATED APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/185103
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are an information sending method, an information receiving method, a related apparatus and a system. The method comprises: sending a first data packet to a server, the first data packet being used for determining first coordinate transformation information, and the first coordinate transformation information being used for performing coordinate transformation between a first coordinate system and a second coordinate system; on the basis of the first coordinate system, generating first position information of a first position point; and sending a second data packet, the second data packet carrying the first position information. The first position information and the first coordinate transformation information are sent by being carried in different data packets and thus can be transmitted by using two different secure channels, and deviation of the two pieces of information is not needed, thereby causing no precision loss of position information, ensuring both compliance and data security, and also reducing the data transmission amount of position information and saving the bandwidth.
