Monitoring system and vehicle surrounding monitoring system
View Patent ↗A parameter selection section selects one from a plurality of image synthesis parameters stored in a parameter storage section according to an output of a vehicle state detection section. An image synthesis section reads out camera images from frame memories according to the selected image synthesis parameter and generates a synthesized image showing a state of vehicle surroundings. A moving object detection section detects, in the thus generated synthetic image, a moving object region estimated as a region where a moving object is present.
1. A monitoring system to which camera images shot by a plurality of cameras installed to a moving body are input, comprising:
a parameter storage section for storing a plurality of image synthesis parameters each expressing correspondence between camera images and a synthetic image and a plurality of detection parameters each defining specification of moving object detection;
a parameter selection section for selecting each one from the plurality of image synthesis parameters and the plurality of detection parameters which are stored in the parameter storage section;
an image synthesis section for generating a synthetic image showing a state of a monitoring region by synthesizing the camera images according to the image synthesis parameter selected by the parameter selection section and for producing a synthetic image output based on the camera images shot by the plurality of cameras; and
a moving object detection section that receives said synthetic image output by the image synthesis section and detects a moving object proximate to the moving body based on the synthetic image and the detection parameter selected by the parameter selection section wherein the moving object is detected in the synthetic image,
wherein the parameter selection section performs parameter selection according to a state of the moving body and taking account of a detection result by the moving object detection section, and
the parameter selection section performs parameter selection taking account of a currently selected image synthesis parameter.
