現(xiàn)有庫WG2CHN,朋友告知為四維的經(jīng)緯度校準(zhǔn)函數(shù)庫，函數(shù)原型如下
WG2CHN_API unsigned int Gps2CN(unsigned int wg_lng,//input WGS84 longitude from GPS (LSB=1/1024 S)
unsigned int wg_lat,//input WGS84 latitude from GPS (LSB=1/1024 S)
int wg_heit,//input present altitude (LSB=1m))
unsigned int *china_lng,//output shifted longitude (LSB=1/1024 S)
unsigned int *china_lat//output shifted latitude (LSB=1/1024 S)
);
不管如何調(diào)用參數(shù)帶入，均失敗，不知法門，只是看到帶入?yún)?shù)類型都是無符整型，所以將經(jīng)緯度全取整小數(shù)點(diǎn)，請(qǐng)了解此庫的朋友幫忙！
unsigned int r = Gps2CN(121462959,31241604,50,&olon,&olat);
