Embodiment approach 1

[0032]The vehicle-mounted shooting device for photographing the vehicle is mounted above the driver's seat in the vehicle compartment to shoot through the front windshield. Such asfigure 1 As shown, the vehicle-mounted imaging device includes the first image pickup apparatus 10 and the second image pickup apparatus 20, the first image pickup apparatus 10 obtains the first image data of a general video image, the general video image by a windshield The reflected video image of the predetermined portion of the compartment generated by the video image and the vehicle due to the windshield is formed, and the second image pickup device 20 obtains the second image of the video image of the predetermined portion of the vehicle compartment of the object reflecting the video image. Image data. The first image pickup apparatus 10 and the second imaging device 20 include cameras 11, 21, data acquisition devices 12, 22, and storage devices 13 and 23, respectively.

[0033]The image data that is ca...

Embodiment approach 2

[0050]A vehicle-mounted imaging device includes a first imaging device 10 and a second imaging device 20, respectively, and the first image pickup apparatus 10 obtains the first image data of the general video image. Wherein, the general video image is formed from a reflected video image transmitted through the windshield through the video image and the predetermined portion of the vehicle generated by the windshield, the second image pickup device 20 obtains a reflection video image. The second image data of the video image of the predetermined portion of the object's compartment. In this embodiment 2, the first imaging device 10 has the function of the second image pickup apparatus 20 to switch the captured area of ​​the camera 11 of the first image pickup apparatus 10.

[0051]That is, ifFigure 5 As shown, the in-vehicle imaging device in Embodiment 2 has a function of switching the captured area of ​​the camera 11. Further, the same reference numerals are denoted by the same or equ...

Embodiment approach 3

[0062]The first imaging device 10 has a function of the second image pickup apparatus 20 to switch the captured area of ​​the camera 11 of the first image pickup apparatus 10. The switching of the photographing area is shown examples of the switching device using an optical system.

[0063]That is, ifFigure 8 As shown, the in-vehicle imaging device in Embodiment 3 includes a mirror 15 as a function of switching the captured area of ​​the camera 11, and is configured to configure the mirror 15 in the captured area of ​​the camera 11 as needed. Further, the same reference numerals are denoted by the same or equivalent portions of the same or corresponding part, respectively.

[0064]Such asFigure 8 As shown, in order to change the shooting area of ​​the camera 11, the mirror 15 is disposed before the camera 11 is disposed on the optical path, and the shooting area of ​​the camera 11 is set to become a compartment of the reflective video image object. The prescribed portion. The insertion op...

Abstract

When, in an onboard imaging device, scenery on a vehicle exterior is being imaged through a windshield (100), scenery inside the vehicle compartment is reflected by the windshield, resulting in background reflection. The present invention is characterized by being provided with, in order to reduce the impact of the background reflection: imaging devices (10, 20) for obtaining first image data of general video of a predetermined portion (101) in the vehicle compartment, which is composed of video reflected by a windshield (100) and transmission video transmitted through the windshield (100), aswell as second image data of the predetermined portion in the vehicle compartment; an image conversion device (30) for converting the second image data to third image data equivalent to the video reflected by the windshield (100); and an image correction device (40) for correcting the first image data on the basis of the third image data.

Description

Technical field[0001]The present application relates to a vehicle-mounted imaging device and a vehicle-mounted image recognition device.Background technique[0002]The vehicle-mounted shooting device for photographing the vehicle is mounted above the driver's seat in the cabin to shoot through the front windshield (windshield). However, there is a problem with the instrument panel in the car that is irradiated with light outside the body, reflecting the surface of the front windshield to reflect the image pickup apparatus. In order to prevent this from being introduced, various types of cars are proposed.[0003]One of them is to provide a linear polarizing filter in an encompassed optical path of the imaging lens into the vehicle-mounted shooting device, specifically, a linear polarizing filter is attached to the lower portion of the imaging lens (Patent Document 1). However, if a linear polarizing filter is attached to the lower part of the imaging lens, there is a problem that hinder...
