WitrynaOBB是一种线性复杂度的最小有向包围盒的估计算法,广泛应用于光线追踪和碰撞检测中。 其根据物体本身的几何形状来决定盒子的大小和方向,盒子无须和坐标轴垂直。 这样就可以选择最合适的最紧凑的包容盒子。 OBB盒子的生成比较复杂。 一般是考虑物体所有的顶点在空间的分布,通过一定的算法找到最好的方向 (OBB盒子的几个轴)。 本文仅对 … Witrynatrimesh.bounds. Do an axis aligned bounding box check on a list of points. Given a pair of axis aligned bounds, return all 8 corners of the bounding box. Find the approximate minimum volume cylinder which contains a mesh or a a list of points. Samples a hemisphere then uses scipy.optimize to pick the final orientation of the …

WitrynaIf an object is rotated, the bounding box aspect-ratio can vary significantly. For unsymmetric objects this leads to highly varying mask targets with respect to the bounding box, even axis-aligned oriented Fig. 1: Benefits of oriented instance segmentation.
