Problems solved by technology

[0005] In the technology described in the above-mentioned Patent Document 1, if the outer diameter of the tire of the vehicle changes, such as when the tire is changed, in one bird's-eye view image, there may be a difference between the captured image captured at the current time and the captured image captured before the current time. Deviations occur near the boundaries of the history image to

no. 1 approach

[0028] The following is attached Figure 1 The first embodiment of the present disclosure will be described first.

[0029] The vehicle display system 1 of the present embodiment is mounted on a vehicle, such as figure 1 As shown, a vehicle-mounted camera group 2 , a sensor group 3 , an image processing device 4 , and a display device 5 are provided. The image processing device 4 is a vehicle image processing device in the present disclosure.

[0030] The vehicle-mounted camera group 2 is composed of a front camera 11 and a rear camera 12 . The front camera 11 is mounted on the front side of a vehicle (hereinafter referred to as the own vehicle) on which the vehicle display system 1 is mounted, and repeatedly captures images of the ground in front of the own vehicle. The rear camera 12 is installed on the rear side of the own vehicle, and repeatedly photographs the ground surface behind the own vehicle.

[0031] The sensor group 3 is composed of a vehicle speed sensor 21 ,...

no. 2 approach

[0086] below, with Figure 1 First, the second embodiment of the present disclosure will be described. However, in the second embodiment, the parts different from the first embodiment will be described.

[0087] The vehicle display system 1 of the second embodiment is the same as the first embodiment except that the tire parameter update process is changed.

[0088] The tire parameter update process of the second embodiment is the same as the first embodiment except that the processes of S270 to S290 and S320 to S360 are omitted and the processes of S410 to S490 are added.

[0089] That is, if Figure 7 As shown, when the measurement object is detected (S260: YES), in S410, the moving distance and moving direction of the host vehicle are calculated in the same manner as in S80. Then, in S420, the front top image stored in the storage unit 34 is used to create a position comparison image representing the rear display region R2 and the middle display region R3, and the create...

no. 3 approach

[0102] The following is attached Figure 1 A third embodiment of the present disclosure will be described first. However, in the third embodiment, the parts different from the first embodiment will be described.

[0103] The vehicle display system 1 of the third embodiment is the same as that of the first embodiment except that the tire parameter update process is changed.

[0104] The tire parameter update process of the third embodiment is a process that is repeatedly executed at a preset execution cycle during the operation of the image processing device 4 .

[0105] When this tire parameter update process is executed, the control unit 35 will Figure 9 As shown, firstly, in S610, it is judged whether the preset processing start condition is satisfied. The processing start condition of this embodiment is that the tire parameter update button provided in the vehicle compartment is pressed.

[0106] Here, when the processing start condition is not satisfied (S610: NO), th...

Abstract

An image processing device for a vehicle, which generates a vehicle surroundings image of an overhead view of the surroundings of the vehicle as seen from above, the image processing device being provided with: a surroundings image acquisition unit (S30) that acquires a photographed front image and a photographed rear image from a front photographic device (11) and a rear photographic device (12); a calculation unit (S80) that calculates the moving distance of the vehicle using vehicle state information, including the information associated with the tire rotation angle of the vehicle, and parameter information associated with the tire outer diameter stored in a storage unit (34); a composite image creation unit (S100, S110, S120) that creates a vehicle surroundings image by using, as a history image, one past image of a region in the traveling direction of the vehicle among the photographed front image and photographed rear image, and compositing the history image with the other image on the basis of the moving distance; and a tire parameter updating unit (S250 to S360, S440, S480, S490) that updates the parameter information stored in the storage unit so as to reduce the deviation between the history image and the other image composited on the basis of the moving distance.

Description

[0001] This application claims priority based on Japanese Application No. 2014-178098 filed on September 2, 2014, and Japanese Application No. 2015-010341 filed on January 22, 2015, and the contents thereof are cited here. technical field [0002] The present disclosure relates to an image processing device for a vehicle that processes an image captured by an imaging device installed in the vehicle. Background technique [0003] Conventionally, it is known to continuously photograph a part of the periphery of a vehicle, convert the captured image captured at the current time and the image captured before the current time into an image viewed from above the vehicle and join them together to create a bird's eye view of the vehicle. A technology of a top view image of a whole and its surroundings (for example, refer to Patent Document 1). [0004] Patent Document 1: Japanese Patent Laid-Open No. 2002-373327 [0005] In the technology described in the above-mentioned Patent Doc...
