Problems solved by technology

[0006] The disadvantages of these existing technologies are: although the street view map captures the three-dimensional scene of the road surface, it is only limited to the scene of the street and some specific places, and rarely provides maps of other places
Moreover, these map data are all photos taken during manual surveying and mapping, the workload is heavy, and they are not real-time, so they cannot provide real-time scene information.
In addition, the cameras on one or two devices can only obtain the scene at the current location, and the obtained scene range is small, and can only obtain images within a certain viewing angle range, and cannot obtain the whole picture of the object

Embodiment 1

[0037] see figure 1 with figure 2 as shown, figure 1 It is a structural block diagram of a device for providing a real-time scene map in Embodiment 1 of the present invention, figure 2 It is a schematic structural diagram of a helmet device in a device for providing a real-time scene map according to Embodiment 1 of the present invention. The device includes a helmet device 1 and a computer 2 . The helmet device 1 includes a helmet body 11 , a wireless communication module 12 and multiple cameras 13 . The cameras 13 are installed around the helmet body 11 and can capture scene information around the helmet device 1 in real time. In order to be able to capture a three-dimensional scene map, the number of cameras 13 is set to at least four, and in this embodiment there are four cameras, which are respectively installed on the front, rear, left, and right sides of the helmet body 11 . The camera 13 is connected with the wireless communication module 12, and the wireless com...

Embodiment 2

[0040] see image 3 As shown, it is a structural block diagram of an apparatus for providing a real-time scene map according to Embodiment 2 of the present invention. In this embodiment, on the basis of Embodiment 1, a display device is added. The display device in this embodiment is a display screen 14 installed on the helmet body 11 . Because the display screen 14 is installed on the helmet body 11, so its volume has certain requirements, it is best to generally select the display screen 14 of small volume. In this embodiment, the display screen 14 adopts a glasses-type miniature display screen. The camera 13 sends the captured scene images to the display screen 14 , and the display screen 14 can be directly used to display the scene images captured by a single camera 13 . In addition, the computer 2 transmits the processed 360-degree panoramic image to the display screen 14 through the wireless communication module 12, so the display screen 14 can also be used to display...

Embodiment 3

[0048] see Figure 5 As shown, it is a structural block diagram of an apparatus for providing a real-time scene map according to Embodiment 3 of the present invention. The difference between this embodiment and Embodiment 2 is: the display device in this embodiment is a remote display screen 3, the remote display screen 3 is generally located in the control center, and the display screen 3 is connected to the computer 2 of the control center at the same time. The display screen 3 may be the display screen 3 of the computer 2 in this embodiment, or a display screen 3 provided separately. The scene image captured by the camera 13 is transmitted to the computer 2 through the wireless communication module 12, and then sent to the display screen 3 by the computer 2, and the display screen 3 can be used to display the scene image captured by a single camera 13. In addition, the computer 2 also directly sends the processed 360-degree panoramic image to the display screen 3, so the d...

Abstract

The invention relates to the technical field of geographic information system, and provides a device for providing a real-time scene graph. A scene image around a helmet device is shot in real time by using a camera on a single helmet device, the shot scene image is transmitted to a computer for being processed, and a three-dimensional scene graph can be obtained in real time; in the same scene, scene images of an object with different angles are shot through at least three helmet devices, and are fused and split-jointed through a computer, and a three-dimensional close-up view of the object can be obtained; in different scenes, through the mutual communication among multiple helmet devices, the single helmet device is capable of obtaining the scene images shot by other helmet devices, and a wide-range real-time scene graph is obtained; each helmet device is communicated with an intermediate server, each single helmet device can obtain scene images of different scenes according to self needs, and a wide-range real-time scene graph can be obtained.

Description

technical field [0001] The invention relates to the technical field of geographic information systems, in particular to a device for providing real-time scene maps. Background technique [0002] A map is a way to describe geographic location and scene information, which is mainly obtained through manual mapping and camera capture of surrounding images. With the development of science and technology, the GPS (Global Positioning System, Global Positioning System) navigation and positioning system has been widely used in today's life. For example, electronic maps and navigators on the Internet. However, most of the current maps are mainly two-dimensional planar maps, which can only provide two-dimensional geometric position information with limited accuracy. However, there are still few 3D maps that can provide richer scene information, and the existing 3D maps have limited regionalization, for example, 3D maps that only provide street views, and are not real-time 3D maps. ...
