摘要： Objects are tracked in real time in a composed video acquired by joining a plurality of videos. A grouping candidate determining unit extracts objects present within an overlapping area, in which pieces of frame data are overlapped, among objects that have been detected and tracked in each of a plurality of pieces of frame data that were captured at the same time as candidate objects. A grouping unit arranges a plurality of candidate objects of which a degree of overlapping is equal to or larger than a predetermined threshold as a group, and an integration unit assigns integration object IDs to groups and objects that have not been grouped.

摘要： To more reliably control synchronous between pieces of video/audio data from a plurality of imaging system devices. A synchronous control unit 15 that synchronizes a plurality of pieces of video/audio data transmitted individually from a plurality of imaging system devices 2 includes a frame acquisition unit 151 configured to acquire a plurality of pieces of frame data from the pieces of video/audio data and assign a frame timestamp based on an acquisition time to each of the plurality of pieces of frame data, for each of the pieces of the video/audio data, and a frame shaping unit 152 configured to assign a new frame timestamp to the plurality of pieces of frame data based on a value of the frame timestamp so that start times of the plurality of pieces of frame data that are close in time among the plurality of pieces of video/audio data are equal to each other, and time intervals between the plurality of pieces of frame data are equal to each other.

摘要： A synchronous shift of video/audio data between a plurality of display system devices is suppressed. A synchronous control device includes a coded-data adjustment unit 312 or a video and audio data adjustment unit 314 configured to perform frame adjustment based on a predetermined frame adjustment instruction by inserting predetermined frame data into a plurality of pieces of frame data in a chronological order or deleting a piece of frame data from the plurality of pieces of frame data, a video and audio data output unit 315 configured to sequentially output each piece of frame data subjected to the frame adjustment, and a video and audio data output time-point adjustment unit 316 configured to compare a reference time point for outputting each piece of the frame data with an output time point at which each piece of the frame data is output. In the synchronous control device, the video and audio data output time-point adjustment unit 316 issues the frame adjustment instruction to insert predetermined frame data if the output time point precedes the reference time point by a threshold value or longer, and alternatively issues the frame adjustment instruction to delete a piece of frame data if the output time point is delayed from the reference time point by a threshold value or longer.

摘要： To suppress an unnatural movement of a moving object at a connection point when a plurality of pieces of video data are connected to each other. A frame acquisition unit 22 acquires pieces of frame data captured at the same time, from the pieces of video data input from cameras C1 and C2. A prohibited-region setting unit 24 sets a prohibited region that is not set as a calculation target when a seam is calculated, based on a position of an object detected in an overlap region between adjacent pieces of frame data and a movement direction of the object. A seam calculation unit 25 calculates a seam between pieces of frame data adjacent to each other, without setting a pixel included in the prohibited region as the calculation target of seam calculation. A connection-frame output unit 26 connects pieces of frame data in accordance with the seam and outputs connection frame data 15.
