Embodiment approach 1

[0039] Below, use figure 1 The configuration of the driving assistance image display system according to Embodiment 1 of the present invention will be described.

[0040] The driving assistance image display system according to Embodiment 1 includes an imaging device 1 , a navigation device 2 , a display unit 3 , and a driving assistance image generation device 4 . The imaging device 1 , the navigation device 2 , the display unit 3 , and the driving assistance image generation device 4 are wired or wirelessly connected via the on-vehicle LAN 5 . Furthermore, a driving assistance image display device is constituted by the display unit 3 and the driving assistance image generating device 4 .

[0041] The imaging device 1 is a camera mounted on the front exterior of a vehicle, captures a landscape image including reminders on or around the road, and acquires the landscape image as an image. Here, a reminder refers to a traffic sign, a store signboard, or a text graffitied on th...

Embodiment approach 2

[0072] The driving assistance image display system according to Embodiment 2 is characterized in that the character indicating the distance marked on the imaged reminder is changed according to the moving distance traveled by the vehicle. In the present embodiment, the position of the vehicle is used as driving assistance information as the information related to the characters indicating the distance marked on the reminder.

[0073] Below, use Figure 9 to Figure 12 A driving assistance image display system according to Embodiment 2 will be described. Figure 9 It is a configuration diagram of a driving assistance image display system according to Embodiment 2, and is a diagram showing the configuration of a driving assistance image generation device in detail. Figure 10 It is an operation flowchart of the driving assistance image display system according to the second embodiment. Figure 11 It is a diagram explaining the relationship between the vehicle movement distance ...

Embodiment approach 3

[0094] The driving assistance image display system according to Embodiment 3 is characterized in that a driving assistance image is generated by photographing reminders showing distances to road junctions such as intersections and street corners, and replacing them in correspondence with passing junctions. The text representing the distance is obtained. In addition, in the present embodiment, the position of the vehicle is used as driving support information as information related to characters indicating distances.

[0095] Below, use Figure 13 to Figure 15 A driving assistance image display system according to Embodiment 3 will be described. Figure 13 This is an example in which the driving assistance image display system according to Embodiment 3 replaces the characters indicating the distance marked on the reminder. Figure 14 It is an operation flowchart of the driving assistance image display system according to the third embodiment. Figure 15 This is an example of...

Abstract

This driving-support-image generation device is provided with a character recognition unit and an image processing unit. The character recognition unit recognizes text in an image that represents the posting content of a posted object posted on or near a road. On the basis of the text recognized by the character recognition unit and driving-support information associated with said text, the image processing unit generates a driving-support image by changing the image of the posted object into an image corresponding to the aforementioned driving-support information.

Description

technical field [0001] The present invention relates to a driving assistance image generation device, a driving assistance image display device, a driving assistance image display system, and a driving assistance image generation program for assisting driving by displaying reminders on or around the road on a display unit in a vehicle. Background technique [0002] Traffic signs indicating information such as speed limits or no parking are indicated on the road. Although the passenger of the vehicle recognizes the traffic sign visually, it is necessary to move the line of sight to the traffic sign, and the passenger often misses the traffic sign. A technique has been proposed in which a camera installed in a vehicle is used to obtain an image of the scenery ahead of the road, and a traffic sign is recognized from the obtained image and displayed on a display unit so that the passenger may miss the traffic sign. In some cases, it is possible to confirm a missed traffic sign ...
