no. 1 approach

[0052] figure 1It is a block diagram showing a configuration example of the bird's-eye view video generation system according to the first embodiment. The bird's-eye view image generation system 1 generates a bird's-eye view image 100 of the vehicle (refer to figure 2 ). The bird's-eye view video generation device 40 and the bird's-eye view video generation system 1 are mounted on a vehicle. The bird's-eye view video generation device 40 and the bird's-eye view video generation system 1 may be portable devices that can be used in a vehicle instead of being mounted on a vehicle.

[0053] use figure 1 The bird's-eye view video generation system 1 will be described. The bird's-eye view image generation system 1 has a front camera (camera) 11, a rear camera (camera) 12, a left camera (camera) 13, a right camera (camera) 14, a left front sensor (obstacle detection unit) 21A, and a front center sensor. (obstacle detection unit) 21B, right front sensor (obstacle detection unit)...

[0107] refer to Figure 6 , Figure 7 , the bird's-eye view video generation system 1 according to this embodiment will be described. Figure 6 It is a flowchart showing the flow of processing in the bird's-eye view video generation device of the bird's-eye view video generation system according to the second embodiment. Figure 7 It is a figure which shows an example of the bird's-eye view video generated by the bird's-eye-view video generation system concerning 2nd Embodiment. The basic configuration of the bird's-eye view video generation system 1 is the same as that of the bird's-eye view video generation system 1 of the first embodiment. In the following description, the same reference numerals or corresponding reference numerals are assigned to the same constituent elements as those of the bird's-eye view video generation system 1 , and detailed description thereof will be omitted. The overhead video generation system 1 of the present embodiment differs from the bird'...

[0137] refer to Figure 8 , the bird's-eye view video generation system 1 according to this embodiment will be described. Figure 8 It is a flowchart showing the flow of processing in the bird's-eye view video generation device of the bird's-eye view video generation system according to the third embodiment. The bird's-eye view video generation system 1 of the present embodiment differs from the bird's-eye view video generation system 1 of the second embodiment in the processes of the obstacle information acquisition unit 43, the superimposed video generation unit 47, and the control unit 41.

[0138] The left front sensor 21A, front center sensor 21B, right front sensor 21C, left rear sensor 22A, rear center sensor 22B, and right rear sensor 22C use a range farther than the range displayed as the bird's-eye view image 100 as a detection range.

[0139] The obstacle information acquiring unit 43 acquires obstacle information of obstacles detected in a range farther than the r...

Abstract

It is characterized in that it has: an image acquisition unit (42) that acquires a surrounding image obtained by photographing the surrounding area of ​​the vehicle; an obstacle information acquisition unit (43) that acquires obstacle information of an obstacle detected around the vehicle; The generating unit (46) generates a bird's-eye view image that has undergone viewpoint conversion processing in a way of viewing the vehicle from above from the surrounding image acquired by the image acquiring unit (42); the superimposed image generating unit (47) generates Obstacle information acquired by the acquisition unit (43) generates a bird's-eye view image obtained by superimposing information representing obstacles on a central portion surrounded by the bird's-eye view image; and a display control unit (48) causes the display panel (31) to display the superimposed image The bird's-eye view image generated by the generation unit (47).

Description

technical field [0001] The present invention relates to a bird's-eye view image generation device, a bird's-eye view image generation system, a bird's-eye view image generation method, and a storage medium. Background technique [0002] A technique related to a vehicle peripheral display device that displays a vehicle's bird's-eye view video together with a vehicle image is known (for example, refer to Patent Document 1). [0003] In addition, the display panels of in-vehicle devices such as navigation devices that display a bird's-eye view image of a vehicle are often horizontally elongated. Therefore, the vertically long bird's-eye view image cannot be displayed on the entire surface of the display panel. Therefore, a technique is known in which, when an obstacle approaching the own vehicle is detected, a bird's-eye view video of the vehicle and a video taken in the direction of the obstacle are displayed side by side (see, for example, Patent Document 2). [0004] prior...
