四元数解算姿态Matlab程序代码
- 四元数是简单的超复数。 复数是由实数加上虚数单位 i 组成,其中i^2 = -1。 相似地,四元数都是由实数加上三个虚数单位 i、j、k 组成,而且它们有如下的关系: i^2 = j^2 = k^2 = -1, i^0 = j^0 = k^0 = 1 , 每个四元数都是 1、i、j 和 k 的线性组合,即是四元数一般可表示为a + bk+ cj + di,其中a、b、c 、d是实数。 对于i、j、k本身的几何意义可以理解为一种旋转,其中i旋转代表X轴与Y轴相交平面中X轴正向向Y轴正向的旋转,j

equalize_hist
- 1. 均值滤波:即线性滤波,有: a.邻域平均, b. 加权平均两种。 a. 邻域平均:用一个像素邻域平均值作为滤波结果,此时滤波器模板的所系数都取1,为保证输出图仍在原来的灰度值范围,在算得R后要将其除以系数总个数再进行赋值,对3*3的模板来说,在算得R后要将其除以系数9。 b. 加权平均:对同一尺寸的模板,可对不同位置的系数采用不同的数值,一般认为离对应模板中心像素近的像素应对滤波结果又较大贡献,所以接近模板中心的系数可比较大而模板边界附近的系数应比较小。(1. mean filter
