Method, device and system for real-time multi-camera tracking of a target object

A non-transitory computer program comprising executable instructions which, when executed by a computing apparatus, implement a method for real-time multi-camera tracking of a target object from a reference list comprising at least one tracklet belonging to said target object, wherein said at least one tracklet comprises a reference tracklet, said method comprising:

• tracking said target object, carried out for at least one new tracklet captured by at least one camera of a plurality of cameras, said tracking comprising
• calculating at least a first distance between said at least one new tracklet and at least one reference tracklet;
• when a smallest calculated first distance is between a first predetermined threshold comprising a re-identification threshold, and a second predetermined threshold comprising a human threshold, greater than said re-identification threshold, presenting said at least one new tracklet to an operator, for said operator to assign or not assign said at least one new tracklet to said target object, manually;
• wherein the human threshold is a function of a number of reference tracklets in said reference list.

A device for real-time multi-camera tracking of a target object from a reference list comprising at least one tracklet belonging to said target object, wherein said at least one tracklet comprises a reference tracklet, said device comprising:

• a means for tracking said target object, carried out for at least one new tracklet captured by at least one camera of a plurality of cameras, said tracking comprising
• calculating at least a first distance between said at least one new tracklet and at least one reference tracklet;
• when a smallest calculated first distance is between a first predetermined threshold comprising a re-identification threshold, and a second predetermined threshold comprising a human threshold, greater than said re-identification threshold, presenting said at least one new tracklet to an operator, for said operator to assign or not assign said at least one new tracklet to said target object, manually;
• wherein the human threshold is a function of a number of reference tracklets in said reference list.
