Problems solved by technology

[0007] However, in a car navigation system incorporating a search-type landscape display device, it is difficult for the user to correctly recognize the relationship between an arbitrary position on a two-dimensional map image and an arbitrary object in the actual scenery as a three-dimensional image.
In addition, in a state where the map image and the actual scenery gradually change as the vehicle moves, it is more difficult for the driver or passengers who are actually driving the vehicle to perform this recognition.

no. 1 approach

[0038] Such as figure 1 As shown, the information display device IDA according to the first embodiment of the present invention includes a real shot image acquisition unit 1, a location information acquisition unit 2, a camera attribute information acquisition unit 3, a map information storage unit 4, and a structure correspondence relationship acquisition unit 5. , an input unit 6 , an image display unit 7 and a control unit 8 . The real-shot image acquisition unit 1 includes a camera that captures real scenery to generate real-shot image data DIc. Captured images can be either still images or moving images. In this embodiment, it is assumed that the camera is installed so as to be able to photograph the front of the vehicle. Also, the actual scenery image captured by the camera is output as actual image data DIc. In addition, for the sake of convenience, the real-shot landscape image represented by the real-shot image data DIc is called a real-shot image IC.

no. 2 approach

[0079] Below, refer to Figure 9 and Figure 10 An information display device according to a second embodiment of the present invention will be described. In the information display device IDA according to the first embodiment described above, in response to designation of a structure on the real-shot image IC displayed on the image display unit 7 , the corresponding structure on the map image IM is highlighted and displayed. However, in the information display device IDAr (not shown) according to the present embodiment, in response to the designation of the structure on the map image IM by the user, the structure on the real image IC is highlighted and displayed. In addition, the information display device IDAr basically has the same configuration as the information display device IDA.

[0080] exist Figure 9 In this case, the user, that is, the vehicle equipped with the information display device IDAr is basically in the same position as the above-mentioned figure 2 (a...

no. 3 approach

[0096] Next, refer to Figure 12 An information display device IDArr (not shown) according to a third embodiment of the present invention will be described. In the above-mentioned embodiment and its modifications, when the user designates a structure in the real-shot image IC or the map image IM, the user can easily understand that the actual scenery is captured by displaying the corresponding structure in the other image with emphasis. Correspondence between the structures on the real shot image IC and the structures on the map image IM. In addition, when the user designates both a structure in the real-shot image IC and a structure in the map image IM, it is effective to change the method of emphasizing the structures in the order specified by the user.

[0097] refer to Figure 12 The operation of the information display device IDArr according to this embodiment will be described. in addition, Figure 12 The flow chart shown is the same as above except that step S102, t...

Abstract

The aim of the invention is to provide an information display device providing a user with a correlation between the position in an actual view and a map image. In the information display device (IDA, IDAr), a real-image acquisition section (1) acquires a real image (IC), a map-information storage section (4) stores map information (IG) and generates a map image (IM), an image display section (7,8) displays the real image (IC) and the map image (IM), an input section (6) specifies, based on operation of the user, at least either of structural objects (Rc / Rg) displayed in either the real image (IC) or the map image (IM), and a structural object correlation acquisition section (5) acquires a correlation (ICb) between a structural object displayed in the real image (IC) and a structural object displayed in the map image (IM).

Description

technical field [0001] The present invention relates to an information display device for notifying users of geographical information by displaying the corresponding relationship between real shot images and map images. Background technique [0002] Conventionally, various car navigation devices have been widely used as representative examples of systems for notifying users of geographic information about their current location and its surroundings. In a conventional car navigation device, the user is notified of geographical information of the surrounding area by displaying the surrounding area information on a display on a map stored in a recording medium such as an HDD (hard disk device) or DVD together with a map image. vehicle position. [0003] In addition, in recent years, in order to enable users to understand surrounding information more intuitively, a search-type landscape marking device that notifies users of surrounding geographical information using real-shot i...
