Provided are a pedestrian search method, a server, and a storage medium. The pedestrian search method is described as follows: a pedestrian detection is performed on each segment of monitoring video to obtain multiple pedestrian tracks, where each pedestrian track of the multiple pedestrian tracks includes multiple video frame images of a same pedestrian; and pedestrian tracks belonging to the same pedestrian is determined according to video frame images in the multiple pedestrian tracks, and the pedestrian tracks of the same pedestrian are merged.

Pedestrian search method, server, and storage medium

An object tracking method is provided. The method includes obtaining current position coordinates of a tracked object for a first time using a tracking algorithm and initializing a filter acting on a time-varying system based on the obtained current position coordinates. The method further includes updating a system state through the filter acting on the time-varying system when the tracking algorithm outputs new current position coordinates of the tracked object with a spatial delay and comparing speed of the tracked object to a compensation determination threshold. Further, the method includes when the speed of the tracked object is greater than the compensation determination threshold, compensating the new current position coordinates of the tracked object with the spatial delay through the filter acting on the time-varying system, and outputting the compensated current position coordinates.

Method and apparatus for object tracking and 3D display based thereon

A three-dimensional (3D) display system is provided for displaying a 3D image including a first view image and a second view image to a viewer. The 3D display system includes an arrangement module, a processing module, and a displaying module. The arrangement module is configured to alternatingly arrange display units of the first view image and display units of the second view image on a display panel. The processing module is configured to obtain an information difference of a display unit of the second view image from the display units of the first view image, and re-calculate a pixel value of the display unit of the second view image. The displaying module is configured to display to the viewer the display unit of the second view image with the re-calculated pixel value via a light separation device.

3D virtual training system and method

A 3D display system for displaying a 3D image includes a tracking unit, a pixel panel, a grating array, and a control unit. The tracking unit is configured to determine a spatial position of a viewer of the 3D display system. The pixel panel contains alternatingly arranged display units from two or more view images of the 3D image, and the grating array is coupled to the pixel panel to separate light from the view images from the pixel panel. The control unit is configured to adjust certain parameters of the grating array such that a maximum width of horizontal projection of edges of adjacent display units through the grating array is less than or equal to a inner-eye distance, and a minimum width of horizontal projection of two edges of a single display unit through the grating array is greater than or equal to an outer-eye distance.
