摘要 传统追踪刚体目标方向变化的方法需要限定具体应用场合和适用目标。提出了一种求解目标几何特征的数值计算方法,即用直接计算光栅化曲线的切线倾角,取代通常的曲线拟合法,具有精度高和计算复杂度低的优点,能很好地满足估计目标方向角度变化的需要。实验证明了该方法有效且效果稳定,因不依赖于具体类型的目标,具有较广的适用性。 This paper proposed a numerical calculation method to solve the geometrical characteristic of the objects. Instead of employing the usually used curve fitting, it directly calculated the tangent angle of a raster curve, which enjoyed such merits as high accuracy and low complexity and perfectly made adjustments as to the direction changes of object.
