基于FPGA的超聲波小型空間定位系統(tǒng)設(shè)計

基于FPGA的超聲波小型空間定位系統(tǒng)設(shè)計：討論了一種新型的小型空間定位系統(tǒng)。該系統(tǒng)采用三角形測量原理實現(xiàn)三維精確定位，利用FPGA豐富的查找表結(jié)構(gòu)完成算法?？呻S時根據(jù)實際檢測或?qū)嶒灁?shù)據(jù)更新查找表，降低系統(tǒng)偏差，使其適用范圍更廣，定位精度更高。并采用動態(tài)掃方式將測量結(jié)果實時地顯示出來。

Abstract：A kind of new small space ultrasonic positioning system is introduced in this paper． The system uses the triangle survey principle to realize three dimensional positioning and USeS the rich lookup table structure of FPGA to complete the algorithm． It can renew the lokup table according to the actual examination or the experimental data，and it can also reduce the system deviation，which means a better positioning an d a wider application．And the measuring result Can be displayed immediately through dynamic scanning．
