【摘要】：對(duì)目標(biāo)在雙目水平平面上深度非對(duì)稱的注視點(diǎn)轉(zhuǎn)移任務(wù),提出了一種基于注視點(diǎn)水平方向轉(zhuǎn)移幅度的分段式頭眼協(xié)調(diào)控制策略,并建立了注視轉(zhuǎn)移運(yùn)動(dòng)控制模型。水平方向注視轉(zhuǎn)移幅度小于頭部運(yùn)動(dòng)閾值,眼球做掃視-異向運(yùn)動(dòng);水平方向注視轉(zhuǎn)移幅度大于頭部運(yùn)動(dòng)閾值且小于眼球轉(zhuǎn)動(dòng)的飽和閾值時(shí)頭眼協(xié)調(diào)運(yùn)動(dòng);當(dāng)水平方向注視轉(zhuǎn)移幅度大于眼球轉(zhuǎn)動(dòng)飽和閾值時(shí),頭部先運(yùn)動(dòng)使目標(biāo)處于眼球運(yùn)動(dòng)可達(dá)范圍,再進(jìn)行頭眼協(xié)調(diào)運(yùn)動(dòng)完成注視轉(zhuǎn)移。仿真實(shí)驗(yàn)證實(shí)了方案可行性和有效性,適用于仿生眼雙目水平平面上視線切換。
[Abstract]:A segmented head-eye coordination control strategy based on horizontal shift amplitude of fixation point is proposed for the target with asymmetric depth on the binocular horizontal plane. The control model of fixation transfer movement was established. The horizontal fixation shift amplitude was less than the threshold of head movement, and the eyeball was saccade and contralateral movement. When the horizontal fixation shift amplitude is larger than the head motion threshold and is smaller than the saturation threshold of eye rotation, the head-eye coordinated movement; When the horizontal fixation shift amplitude is larger than the saturation threshold of eye rotation, the head movement makes the target within the range of eye movement. The simulation results show that the proposed scheme is feasible and effective, and it is suitable for the line of sight switching on the binocular horizontal plane of bionic eyes.

【正文快照】： 引言1人類視覺具有快速定位、準(zhǔn)確跟蹤、運(yùn)動(dòng)中穩(wěn)定清晰成像的優(yōu)異性能,這些性能的實(shí)現(xiàn)都依賴于雙目水平平面的注視轉(zhuǎn)移。生理機(jī)制的研究成果表明[1-2],水平面上較小幅度的注視轉(zhuǎn)移,由眼球掃視-異向復(fù)合運(yùn)動(dòng)即可完成;當(dāng)水平面上注視轉(zhuǎn)移幅度超出一定視野范圍,就需要頭眼相互配，
