Embodiment Construction

[0047] figure 1 The adaptive automatic object tracking system includes at least one video capture device for supplying at least one video stream. In the non-limiting example shown, the system comprises n, more precisely, n video cameras 10 1 ,...,10 i ,...,10 n , for serving n video streams. Each of them shoots the scene and transmits a corresponding video stream through the computer connection.

[0048] The system also includes a collector 12 of n video streams for transmitting the video streams to a primary stage of tracking devices designed to detect and automatically track by analyzing the video streams they respectively receive at least one target.

[0049] In the example shown, the primary level consists of:

[0050] -n tracking devices 14 1 ,...,14 i ,...,14 n , for separately processing from n video cameras 10 1 ,...,10 i ,...,10 n n video streams output and transmitted by collector 12, and

[0051] - an additional reference tracking device 14 according to...

Abstract

The invention relates to an adaptive system and method for automatically tracking at least one target in at least one video stream. The system includes at least one dynamically configurable tracking device (141,...,14n), receiving a video stream and, adapted for detection and automatic tracking of at least one target by analysis of the video stream; a calculator (20) of a metric performance valuestarting from a target tracking result (R1,...,Rn) supplied by the tracking device; a configuration parameter corrector (26) of the tracking device as a function of the metric performance value; and adynamic configurator (161,...,16n) of the tracking device by applying the corrected configuration parameter. It further includes a supplementary reference tracking device (14MSTR), receiving at leastone portion of the video stream, and the calculator (20) calculates the metric performance value from a comparison on the video stream portion, of the target tracking result (S1,...,Sn)supplied by the tracking device and a reference tracking result supplied by the supplementary reference tracking device (14MSTR).

Description

technical field [0001] The invention relates to an adaptive system for automatically tracking at least one object in at least one video stream. The invention also relates to a corresponding method and computer program. Background technique [0002] "Target" means a detectable object or human or animal creature to be automatically tracked in one or more video streams by means of known Microprogramming or microwiring to achieve. In other words, the target is an object or creature to be localized in space and time in real time according to the perception of the scene provided by one or more video cameras. [0003] Fields of application include not only real-time detection and automatic tracking of objects in a video stream, detection and automatic tracking of objects in multiple video streams fed in parallel by multiple cameras (a function often referred to as "real-time multi-object tracking"), but also Detect and automatically track multiple targets in multiple video strea...
