Vehicle-mounted image processing device
First Claim
1. A vehicle-mounted image processing device, comprising:
- an image acquisition unit that acquires through-images taken by cameras disposed on front, rear and sides of a vehicle;
a bird'"'"'s eye view image generation unit that converts the acquired through images to generate a bird'"'"'s eye view image;
a parking line recognition unit that performs parking line recognition processing to recognize a parking line based on one or more of the through-images and the bird'"'"'s eye view image,wherein the parking line recognition unit performs;
first parking line recognition processing based on the bird'"'"'s eye view image to recognize a parking line in a predetermined range of the bird'"'"'s eye view image, wherein the first parking line recognition processing is performed in an area surrounding the vehicle and the predetermined range is associated with the area surrounding the vehicle, andsecond parking line recognition processing to set and process only an image processing area of the through images that is further away from the predetermined range of the bird'"'"'s eye view image, and recognize a parking line based on the image processing area of the through-images, andwhen a speed of the vehicle is higher than a first preset threshold, the parking line recognition unit performs both the first parking line recognition processing and the second parking line recognition processing.

Abstract
Provided is a vehicle-mounted image processing device capable of recognizing the outside of a vehicle based on an image taken by a vehicle-mounted camera more precisely. A vehicle-mounted image processing device of the present invention includes: an image acquisition unit (12) that acquires through-images (21) to (24) taken by cameras (1) to (4) disposed on front, rear and sides of a vehicle (10); a bird'"'"'s eye view image generation unit (13) that converts the acquired through images (21) to (24) to generate a bird'"'"'s eye view image (25); a parking line recognition unit (15) that performs parking line recognition processing to recognize a parking line WL based on at least one of the through-images (21) to (24) and the bird'"'"'s eye view image (25). The parking line recognition unit (15) performs first parking line recognition processing (S111) based on the bird'"'"'s eye view image (25) to recognize a parking line WL in a predetermined range of the bird'"'"'s eye view image (25), and second parking line recognition processing (S112) based on the through-images (21) to (24) to recognize a parking line WL in an area that is far away from the predetermined range of the bird'"'"'s eye view image (25).

-
an image acquisition unit that acquires through-images taken by cameras disposed on front, rear and sides of a vehicle; a bird'"'"'s eye view image generation unit that converts the acquired through images to generate a bird'"'"'s eye view image; a parking line recognition unit that performs parking line recognition processing to recognize a parking line based on one or more of the through-images and the bird'"'"'s eye view image; a lane recognition unit that recognizes a vehicle traveling lane based on one or more of the through-images and the bird'"'"'s eye view image; and a scheduling unit that determines whether to execute parking line recognition processing by the parking line recognition unit or lane recognition processing by the lane recognition unit in accordance with the vehicle speed, wherein the parking line recognition unit performs; first parking line recognition processing based on the bird'"'"'s eye view image to recognize a parking line in a predetermined range of the bird'"'"'s eye view image, wherein the first parking line recognition processing is performed in an area surrounding the vehicle and the predetermined range is associated with the area surrounding the vehicle, and second parking line recognition processing to set and process only an image processing area of the through images that is further away from the predetermined range of the bird'"'"'s eye view image, and recognize a parking line based on the image processing area of the through-images, and when the vehicle speed is a first preset threshold or less, the scheduling unit makes the parking line recognition unit only perform parking line recognition processing, when the vehicle speed is higher than the first preset threshold and a second preset threshold or less, the scheduling unit makes the parking line recognition unit perform parking line recognition processing and the lane recognition unit perform lane recognition processing, and when the vehicle speed is higher than the second preset threshold, the scheduling unit makes the lane recognition unit only perform lane recognition processing.
