Image processing device, alarming apparatus, image processing system, and image processing method
First Claim
1. An image processing system comprising:
- a terminal device that is installed on a vehicle; and
a server device that performs communication with the terminal device,wherein the terminal device includesa contrasting correction unit that creates a contrasting corrected image by correcting contrasting an input image captured by a vehicle camera installed on a vehicle,a color analysis unit that creates a color corrected image by correcting colors in the input image,an object detection unit that detects a main sign included in the input image based on the contrasting corrected image and detects an auxiliary sign included in the input image based on the color corrected image, andan image transmission unit that transmits a post-detection image indicating a result of detecting the main sign and the auxiliary sign by the object detection unit to the server device, andwherein the server device includesan image receiving unit that receives the post-detection image transmitted from the terminal device,a second contrasting correction unit that creates a contrasting corrected image by correcting contrasting of the post-detection image received by the image receiving unit,a second color analysis unit that creates a color corrected image by correcting colors of the post-detection image received by the image receiving unit,a second object detection unit that detects a main sign included in the post-detection image based on the contrasting corrected image and detects an auxiliary sign included in the post-detection image based on the color corrected image, andan object relation analysis unit that recognizes a traffic sign as a combination of the main sign and the auxiliary sign by associating the main sign and the auxiliary sign with each other based on a positional relationship between the main sign and the auxiliary sign in the post-detection image received by the image receiving unit.

Abstract
An image processing device includes a contrasting correction unit, a color analysis unit, an object detection unit, and an object relation analysis unit. The contrasting correction unit creates a contrasting corrected image by correcting contrasting of an input image captured by a vehicle camera. The color analysis unit creates a color corrected image by correcting colors of the input image. The object detection unit detects a main sign included in the input image based on the contrasting corrected image and detects an auxiliary sign included in the input image based on the color corrected image. The object relation analysis unit recognizes a traffic sign as a combination of a main sign and auxiliary sign by associating the main sign and the auxiliary sign with each other based on a positional relationship between the main and auxiliary signs, which are detected by the object detection unit, in the input image.
