    Imaging through scattering media has important applications in many fields. However, there are few studies on imaging and tracking of three-dimensional (3D) moving objects through scattering media. In this paper, a method of single-shot videoing for 3D moving objects through scattering layers is proposed. The speckles emitted from two different positions of the scattering layer are uncorrelated and contain the object information under dual view angles. Detecting in the overlapping area of the two parts of the speckles can realize 3D imaging. By rotating the camera around the optical axis during the exposure process, a speckle image consists of a series of momentary speckles with different rotation angles can be detected. With the speckle rotation decorrelation property, these momentary speckles are uncorrelated with each other. Thus, a series of momentary speckles corresponding to different moments and different view angles are multiplexed in a speckle image. Using the cross-correlation deconvolution imaging method, the video information of the 3D moving objects can be reconstructed from this speckle image by rotating the point spread function detected in each single view.
