Abstract
A method and system for analyzing a queue comprising: obtaining a first image acquired at a first time of a first position within a queue; obtaining a second image acquired at a second time of a second position within the queue; detecting a queue member within the first image; detecting a queue member with the second image; determining that the queue member detected within the second image is the same as the queue member detected within the first image; and determining a trajectory of the queue member within the queue based on a difference between the first time and the second time.
Claims20
A computer-implemented method of analysing a queue comprising the steps of:
- (a) obtaining, by a computer processor, a first image acquired at a first time of a first position within a queue;
- (b) obtaining, by the computer processor, a second image acquired at a second time of a second position within the queue;
- (c) detecting, by the computer processor, a queue member within the first image;
- (d) detecting, by the computer processor, a queue member within the second image;
- (e) determining, by the computer processor, that the queue member detected within the second image is the same as the queue member detected within the first image;
- and
- (f) determining, by the computer processor, a trajectory of the queue member within the queue based on a difference between the first time and the second time.
A system for analysing a queue comprising:
- a processor configured to:
- (a) receive a first image acquired at a first time of a first position within a queue;
- (b) receive a second image acquired at a second time of a second position within the queue;
- (c) detect a queue member within the first image;
- (d) detect a queue member within the second image;
- (e) determine that the queue member detected within the second image is the same as the queue member detected within the first image;
- and
- (f) determine a trajectory of the queue member within the queue based on a difference between the first time and the second time.
One or more non-transitory computer readable media storing computer readable instructions that, when executed, cause a system to perform a method of analyzing a queue by:
- obtaining a first image acquired at a first time of a first position within a queue;
- obtaining a second image acquired at a second time of a second position within the queue;
- detecting a queue member within the first image;
- detecting a queue member within the second image;
- determining that the queue member detected within the second image is the same as the queue member detected within the first image;
- and
- determining a trajectory of the queue member within the queue based on a difference between the first time and the second time.
