摘要
将判识特征值在设计速度和距离按泰勒公式展开,依据判识距离化趋势,用二元三次函数逼近,建立了空间绝对距离、相对距离判识变化数学模型.结果表明:绝对距离判识值随障碍物深度距离增加而增大,随速度增加减小.相对距离判识受深度距离影响小,速度变化影响大,二元二次函数可很好逼近空间距离判识变化规律.
The paper Disposed these data according to Taylor formula and simulated variation trend with binary cubic function and found cognition mathematics models of absolute and relative distances in day.Test results show that cognitive absolute distances augment with depth distance increasing and decrease with speed increasing.Depth distance has a little impact on relative ones and velocity has a lot impact.Binary quadratic equation can simulate cognition variation laws.
