visibility test

Light signal visibility test hand signals ( made by the driver of a car, etc to show which way it will turn, etc)

灯光信号显示距离测试手势信号（司机指示转弯等的）

Light signal visibility test back focal distance

灯光信号显示距离测试

This method include 3 D Euclidean distance transform, computer the Hessian matrix in every voxel, and visibility test.

主要步骤包括:三维欧几里德距离变换, 求Hessian矩阵, 可视化检测几个步骤.

These two features helped the test team develop and document repeatable test results, meeting the high-visibility challenge.

这两个特性帮助测试团队开发和文档化可重复的测试结果，从而满足“高可见性”的挑战。
