Abstract
Detection means detects a mobile body from each of time-series images obtained by capturing images of a road. Prediction means predicts a destination area of the mobile body by using past information indicating positions where mobile bodies have been detected on the road in the past. In a case where the mobile body is detected from a second image in the destination area that is predicted for the mobile body detected from the first image, tracking means tracks the mobile body detected from the first image and the mobile body detected from the second image as the same mobile body.
Claims9
A mobile body tracking apparatus comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- detect a mobile body from each of time-series images obtained by capturing images of a road;
- predict a destination area of the mobile body by using past information indicating positions where mobile bodies have been detected on the road in the past;
- and
- track, in a case where the mobile body is detected from a second image in the destination area that is predicted for the mobile body detected from a first image included in the time-series images, the second image being captured at a time later than a time at which the first image has been captured, the mobile body detected from the first image and the mobile body detected from the second image as a same mobile body.
A mobile body tracking method comprising:
- detecting a mobile body from a first image included in time-series images obtained by capturing images of a road;
- predicting a destination area of the mobile body detected from the first image by using past information indicating positions where mobile bodies have been detected on the road in the past;
- detecting the mobile body from a second image captured at a time later than a time at which the first image has been captured, the second image being included in the time-series images;
- and
- tracking, in a case where the mobile body detected from the second image is detected in the destination area that is predicted for the mobile body detected from the first image, the mobile body detected from the first image and the mobile body detected from the second image as a same mobile body.
A non-transitory computer readable medium storing a program for causing a computer to execute processing including:
- detecting a mobile body from a first image included in time-series images obtained by capturing images of a road;
- predicting a destination area of the mobile body detected from the first image by using past information indicating positions where mobile bodies have been detected on the road in the past;
- detecting the mobile body from a second image captured at a time later than a time at which the first image has been captured, the second image being included in the time-series images;
- and
- tracking, in a case where the mobile body detected from the second image is detected in the destination area that is predicted for the mobile body detected from the first image, the mobile body detected from the first image and the mobile body detected from the second image as a same mobile body.
