Kinect是正交还是透视模式? [英] Is Kinect orthographic or perspective mode?

问题描述

我想知道Kinect是否捕获orthographic或perspective mode中的颜色，深度和IR图像?

I would like to know if the Kinect capture color, depth and IR images in orthographic or perspective mode?

推荐答案

根据我使用Kinect v1和v2的经验，虽然没有明确提及此特定信息，但我会说以下话:

While there is no clear mention of this particular information, based on my experience of using Kinect v1 and v2, I would say the following:

1. 彩色和红外摄像机:透视图 两者都是带镜头的普通RGB摄像机(红外摄像机带有一个红外滤光片)，并具有摄像机参数，透镜畸变等.图像中的对象越远，它们的尺寸就越小

1. Color and IR cameras: Perspective Both are normal RGB cameras (IR one has an IR filter) with a lens and have camera parameters, lens distortion etc. The objects in image get smaller as they go farther

深度:正交 基于深度的计算方法[4]，深度图像是点云的一种表示形式，它消除了透视感.

Depth: Orthographic Based on how the depth is calculated [4], the depth image is a representation of a point cloud which removes the sense of perspective.

再次，这可能是错误的，但我认为它应该足够接近.抱歉，如果错了.

Again, this might be wrong, but I believe it should be close enough. Apologies if it is wrong.
