VEHICLE PERIPHERY MONITORING DEVICE
First Claim
1. A vehicle periphery monitoring device which detects an object existing outside a vehicle on the basis of a captured image of an area in the periphery of the vehicle acquired by an in-vehicle camera, the device comprising:
- a first edge image generation element configured to extract a first edge as a discontinuous varying portion in a value of a luminance component from the captured image on the basis of the luminance components of the captured image and generates a first edge image which is composed of the extracted first edges;
a second edge image generation element configured to extract a second edge as a discontinuous varying portion in a value of a hue component or a saturation component on the basis of the hue components or the saturation components of the captured image and generates a second edge image which is composed of the extracted second edges;
a composite edge image generation element configured to generate a composite edge image formed by combining the generated first edge image and second edge image; and
an object classification identification element configured to determine whether or not an external shape of the object represented by an object outline image which is an image constituting a visible outline of the object contained in the captured image in the generated composite edge image coincides with an external shape of a prescribed kind of structure and identifies whether or not the object is the prescribed kind of structure on the basis of at least the determination result.

Abstract
A vehicle periphery monitoring device includes: a first edge image generation element 5 which generates a first edge image on the basis of luminance components of a captured image acquired by an in-vehicle camera 2; a second edge image generation element 6 which generates a second edge image on the basis of hue components or saturation components of the captured image; a composite edge image generation element 7 which generates a composite edge image formed by combining the first edge image and the second edge image; and an object classification identification element 8 which identifies whether or not the object is a prescribed kind of structure on the basis of the external shape of the object represented by the composite edge image.
