相机横向运动产生的图像模糊与物体范围成反比。这样的图像，再加上同一场景的未模糊图像（指定的模糊急性对），已被研究，以确定其有用的对象测距。它表明，一个简单的反卷积过程产生的范围时，现场是等晕或可以近似由一组等晕补丁。它还表明，模糊急性对包含更多的信息比立体对，允许解决方案的情况下，是模糊的双目立体。讨论了一种旋转镜方案，该方案能够产生受控的横向运动模糊，而不需要相机本身的运动。<<ETX>>
Lateral camera motion produces image blur inversely proportional to object range. Such an image, coupled with an unblurred image of the same scene (designated a blur-acute pair), has been studied to determine its usefulness for object ranging. It is demonstrated that a straightforward deconvolution process yields range when the scene is isoplanatic or can be approximated by a set of isoplanatic patches. It is also shown that a blur-acute pair contains more information than a stereo pair, permitting solutions in situations that are ambiguous for binocular stereo. A rotating mirror scheme is discussed which is capable of producing controlled lateral motion blur without the need for motion of the camera itself.<<ETX>>
