| 摘 要： | 由于折反射成像的特点,当目标在空间沿直线运动时,在全向图像上的成像轨迹不是直线而是二次曲线,导致在应用普通透视图像的轨迹预测方法时对目标的下一位置预测误差大.本文采用折反射成像统一的球面投影模型把已知的目标在全向图像上的成像点投影到球面上,然后在球面上建立全向卡尔曼滤波器对目标下一个位置进行预测,预测的结果重投影回全向...

| Abstract: | Because of the features of catadioptric imaging,when the object has linear motion in real space,its trajectory on omnidirectional images is not a straight line,but conic.It leads to the big error in prediction of object's next position when applying trajectory prediction method for common perspective image.The authors adopt unifying catadioptric imaging sphere projection model to project object's imaging point in omnidirectional images onto the sphere where the author then establishes omnidirectional kalman... |
