我们基本掌握的是开放式GL物体的模型矩阵表,它为我们提供了轮换和翻译矢量,用一些计算得出了我们的实际立场:
-R*t,其中R为[0 4 8; 1 5 9; 2 6 10] 矩阵和t为[12 13 14]栏矢量。
In OpenCV we have screen coordinates x,y of the fingertip.
现在,我们需要某种方法,将这种屏幕的<代码>x,y与开放式全球坐标相比较,看看哪个物体确实点击。 我们尝试了<代码>glu Un Project,但并未从Xy中恢复正确的世界坐标。
在这里尝试的方法是什么,它正在使用ARToolKit和开放式CV,索模拟根据AR标记的变化矩阵。 我们还使用ARToolkit照相机模块。
Well, let me see: You ve got two knowns for a system of 3 linear independent equations. So you re literally missing some information. You have a free parameter z, and if you think about it, what this gives you is not a position in space, but a ray into it (from the camera into some direction to infinity). You can gluUnProject for z=0 and z=1, which gives you two points on the ray. Then you can use that ray to test if it crosses some of your objects.
或你以其他方式: 您将每一物体的捆绑量用于对空间(x,y)进行筛选,并测试你的inger子坐标。 稍后我发言。
