SYSTEM FOR TRACKING A MOVING OBJECT, AND A METHOD AND A NON-TRANSITORY COMPUTER READABLE MEDIUM THEREOF

摘要

According to one embodiment, a plurality of moving objects is detected from a plurality of frames acquired in time series. Each of the moving objects is corresponded among the frames. A tracklet of each moving object corresponded is extracted and stored. A frame to calculate a position of a moving object is set to a notice frame. The frames are grouped into a first block including at least the notice frame, a second block positioned before the first block in time series, and a third block positioned after the first block in time series. A secondary tracklet included in the second block is acquired from the stored tracklets. The secondary tracklet is corresponded with tracklets included in the first block and the third block, based on a similarity between the secondary tracklet and each of the tracklets. The secondary tracklet is associated with the corresponded tracklets, as a tertiary tracklet.

主权项

1. A system for tracking a moving object, comprising:
an acquisition unit configured to acquire a plurality of frames in time series; a detection unit configured to detect a plurality of moving objects from the frames; an extraction unit configured to correspond each of the moving objects among the frames, and to extract a tracklet of each moving object corresponded; a control unit configured to store the tracklet of each moving object corresponded; a setting unit configured to set a frame to calculate a position of a moving object to a notice frame; a grouping unit configured to group the frames into a first block including at least the notice frame, a second block positioned before the first block in time series, and a third block positioned after the first block in time series; a correspondence unit configured to acquire a secondary tracklet included in the second block from the control unit, and to correspond the secondary tracklet with tracklets included in the first block and the third block, based on a similarity between the secondary tracklet and each of the tracklets; and an association unit configured to associate the secondary tracklet with the corresponded tracklets, as a tertiary tracklet.
