【摘要】:為實(shí)現(xiàn)運(yùn)行體智能自主定位,該文提出一種基于網(wǎng)格細(xì)胞到位置細(xì)胞轉(zhuǎn)換的位置估計(jì)模型。結(jié)合網(wǎng)格細(xì)胞和位置細(xì)胞的放電機(jī)理以及它們之間的信息轉(zhuǎn)換關(guān)系,將位置估計(jì)模型分為空間環(huán)境學(xué)習(xí)與記憶、運(yùn)動(dòng)狀態(tài)感知和位置估計(jì)3部分,給出了各個(gè)部分實(shí)現(xiàn)原理和具體操作步驟,最后利用提出的模型對(duì)運(yùn)行體定位問題進(jìn)行了仿真實(shí)驗(yàn)。結(jié)果表明,所提模型能實(shí)現(xiàn)運(yùn)行體自主定位,且定位性能可通過改變模型中網(wǎng)格細(xì)胞和位置細(xì)胞參數(shù)進(jìn)行調(diào)整。
[Abstract]:In order to realize the intelligent autonomous location of the mobile body, this paper presents a position estimation model based on the transformation of grid cells to position cells, combining the discharge mechanism of grid cells and location cells and the information conversion relationship between them. The location estimation model is divided into three parts: spatial environment learning and memory, motion state perception and position estimation. Finally, the proposed model is used to simulate the problem of moving object positioning. The results show that the proposed model can achieve autonomous positioning of the moving object. The location performance can be adjusted by changing the parameters of grid cells and location cells in the model.
