摘要： A satellite search method is applied to a mobile terminal. The satellite search method includes determining, based on location information of the mobile terminal, location information of an available satellite, and three-dimensional (3D) map information, whether a direct line of sight between the mobile terminal and the available satellite is blocked by an obstacle, and determining location information of a target area based on the 3D map information when the direct line of sight is blocked by the obstacle, where the target area includes a direct line of sight between the mobile terminal and the available satellite.

摘要： A watermarking method for a high-definition map based on invisible characters includes: firstly, establishing mapping relations between invisible characters and bit characters, a space character, and decimal digits; and combining watermark characters with corresponding positions thereof, adding Hamming code into a watermark character sequence, and converting the watermark character sequence into invisible characters to construct a composite watermark character sequence. Before watermark detection, a sequence of elements in map data is scrambled according to logistic chaotic mapping, and then the composite watermark character sequence is embedded according to the scrambled sequence. During watermark detection, the data are preprocessed, a sequence during watermark embedding is obtained, and then watermark information is extracted, errors are corrected, and an error correcting code is removed after correction to obtain final watermark information. According to the watermarking method, watermark embedding and watermark detection can be realized not changing data availability and high-accuracy characteristic.
