STAY DURATION MEASUREMENT DEVICE, STAY DURATION MEASUREMENT SYSTEM AND STAY DURATION MEASUREMENT METHOD
First Claim
1. A stay duration measurement device for measuring a stay duration in a measurement area for each moving object, the stay duration measurement device comprising:
- a processor; and
a memory storing instructions,wherein the processor, when performing the instructions stored in the memory, comprises;
a movement line obtainer that obtains a movement line of each moving object detected from images including the measurement area;
a movement line assessor that determines whether the movement line obtained by the movement line obtainer includes a missing part in the measurement area; and
a stay duration obtainer that, in a case where it is determined by the movement line assessor that the movement line of a moving object of interest includes a missing part in the measurement area, obtains a stay duration compensated for the missing part based on a time period(s) required for movement(s) of one or more other moving objects in the measurement area.

Abstract
A stay duration measurement device for measuring a stay duration in a measurement area for each moving object, includes: a movement line obtaining unit that obtains a movement line of each moving object detected from images including the measurement area; a movement line assessment unit that determines whether the movement line obtained by the movement line obtaining unit includes a missing part in the measurement area; and a stay duration obtaining unit that, in a case where it is determined by the movement line assessment unit that the movement line of a moving object of interest includes a missing part in the measurement area, obtains a stay duration compensated for the missing part based on a time period(s) required for movement(s) of one or more other moving objects in the measurement area.

16. A stay duration measurement system for measuring a stay duration in a measurement area for each moving object, the system comprising:
-
a camera that captures images of a region including the measurement area; and a plurality of information processing devices, wherein the plurality of information processing devices jointly comprise; a moving object detector that detects a moving object from the images captured by the camera and outputs detection position information; a movement line obtainer that obtains a movement line of each moving object based on the detection position information; a movement line assessor that determines whether the movement line obtained by the movement line obtainer includes a missing part in the measurement area; and a stay duration obtainer that, in a case where it is determined by the movement line assessor that the movement line of a moving object of interest includes a missing part in the measurement area, obtains a stay duration compensated for the missing part based on a time period(s) required for movement(s) of one or more other moving objects in the measurement area.

17. A stay duration measurement method for measuring a stay duration in the measurement area for each moving object, the method comprising:
-
obtaining a movement line of each moving object detected from images including the measurement area; determining whether the movement line obtained by the step of obtaining includes a missing part in the measurement area; and in a case where it is determined by the step of determining that the movement line of a moving object of interest includes a missing part in the measurement area, obtaining a stay duration compensated for the missing part based on a time period(s) required for movement(s) of one or more other moving objects in the measurement area, wherein at least one of the obtaining a movement line, the determining whether the movement line includes a missing part in the measurement area, and the obtaining a stay duration compensated for the missing part is performed by a processor.
