立体相机的基线是多少?

有人可以解释一下相机的基线到底是什么吗?

Could someone here explain what exactly is the baseline of a camera?

您显然正在处理立体,其中基线是(至少通常是)两个镜头之间的距离。

You're apparently dealing with stereo, where the baseline is (at least normally) the distance between the two lenses.

我相信

Z (depth) = (focalLength * baseline) / disparity

可以在这里找到其他坐标: http ://www.ptgrey.com/support/kb/index.asp?a=4&q=63&ST=

I believe

Z (depth) = (focalLength * baseline) / disparity

基线(两个相机之间的距离)将影响您可以使用立体相机观察的深度范围以及深度分辨率。这同样适用于您使用的镜头的焦距。

假设您处理大小恒定的视差范围,则适用以下规则:

  • 增加基线将增加深度分辨率,但也会增加到相机的最小距离
  • 增加焦距也会增加深度分辨率和最小距离到相机,同时也会缩小视野。

这种关系可以使用以下在线计算器进行研究:

The baseline (distance between both cameras) will influence the depth range that you can observe with a stereo camera, and also your depth resolution. The same also applies to the focal length of the lenses that you use.

Assuming that you process a disparity range with a constant size, then the following rules apply:

  • Increasing the baseline will increase your depth resolution, but will also increase the minimum distance to the camera
  • Increasing the focal length will also increase the depth resolution and minimum distance to the camera, but also reduce the field of view.

This relationship can be studied with the following online calculator:

基线是两个立体相机之间的距离。
当您进行立体校准时,openCV 方法返回 R、T(相机之间的旋转和平移)

Baseline is the distance between 2 stereo camera.
When you do stereo Calibration, the openCV method return R, T (rotation and translation between your cameras)
