  • 摘要: 為實現(xiàn)運行體智能自主定位，該文提出一種基于網(wǎng)格細(xì)胞到位置細(xì)胞轉(zhuǎn)換的位置估計模型。結(jié)合網(wǎng)格細(xì)胞和位置細(xì)胞的放電機理以及它們之間的信息轉(zhuǎn)換關(guān)系，將位置估計模型分為空間環(huán)境學(xué)習(xí)與記憶、運動狀態(tài)感知和位置估計3部分，給出了各個部分實現(xiàn)原理和具體操作步驟，最后利用提出的模型對運行體定位問題進行了仿真實驗。結(jié)果表明，所提模型能實現(xiàn)運行體自主定位，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)進行調(diào)整。
    Abstract: To achieve intelligent and autonomous positioning for the vehicle, this paper presents a location estimation model based on the transformation from grid cells to place cells. Combining with the firing characteristic of the grid cells, place cells, and the information transformation between them, this location estimation model is divided into three parts, including the learning and memorizing of spatial environment, the perception of the motion state and the estimation of the spatial location. The principle and the specific steps of each part are discussed. Finally, the proposed model is applied to vehicles positioning by simulation. Simulation validates that the proposed model is feasible to achieve vehicles autonomous positioning, and the positioning performance can be adjusted by changing the parameters of grid cells and place cells included in the model.
