【摘要】：對目標在雙目水平平面上深度非對稱的注視點轉(zhuǎn)移任務,提出了一種基于注視點水平方向轉(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)移運動控制模型。水平方向注視轉(zhuǎn)移幅度小于頭部運動閾值,眼球做掃視-異向運動;水平方向注視轉(zhuǎn)移幅度大于頭部運動閾值且小于眼球轉(zhuǎn)動的飽和閾值時頭眼協(xié)調(diào)運動;當水平方向注視轉(zhuǎn)移幅度大于眼球轉(zhuǎn)動飽和閾值時,頭部先運動使目標處于眼球運動可達范圍,再進行頭眼協(xié)調(diào)運動完成注視轉(zhuǎn)移。仿真實驗證實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、準確跟蹤、運動中穩(wěn)定清晰成像的優(yōu)異性能,這些性能的實現(xiàn)都依賴于雙目水平平面的注視轉(zhuǎn)移。生理機制的研究成果表明[1-2],水平面上較小幅度的注視轉(zhuǎn)移,由眼球掃視-異向復合運動即可完成;當水平面上注視轉(zhuǎn)移幅度超出一定視野范圍,就需要頭眼相互配，
