Abstract
With a simple configuration, a vehicle periphery monitoring system that easily detects pedestrian that has a possibility to collide with a vehicle to which the monitoring system is installed. Based on a change rate in the size of the image of the observation object captured at a preset time interval by an onboard camera 111 and the presence or absence of the deformation of the observation object image between the captured images, it is determined whether the observation object is a pedestrian relatively approaching the vehicle to which the monitoring system is installed.
Claims8
A vehicle periphery monitoring system that performs monitoring of a vehicle periphery based on an image of the vehicle periphery captured by an onboard camera, comprising:
- a captured image acquiring unit that acquires a captured image captured by the onboard camera;
- a process region setting unit that sets a process region for detecting an observation object in the captured image acquired by the captured image acquiring unit;
- and
- an object behavior analysis unit that determines whether the observation object is a pedestrian relatively approaching the vehicle to which the monitoring system is installed based on a change rate of a size of an image of the observation object between a plurality of captured images captured at different time points in the process region, and presence or absence of deformation of the image of the observation object between the plurality of captured images captured at different time points in the process region,
- wherein the process region setting unit arranges a plurality of process regions with sizes predetermined based on the size of the pedestrian to be an image capturing object in the captured image.
