JPH02183186A - Map forming apparatus for radar display device - Google Patents

Abstract

PURPOSE:To easily input accurate map data by overlapping and displaying a radar video with a map in forming a map. CONSTITUTION:When coordinates of a map are to be input from a digitizer 1, the coordinates are not picked up from the map, but picked up from a radar video along with runways and guide roads displayed by a display device. In other words, both the radar video 5 and the map display formed by a map forming device 2 are input while the display by a radar video and map synthesizing device 6 is being confirmed. The map obtained in this manner is never shifted from the actual radar video, and therefore making it possible to easily input a highly accurate map. Two or more map forming devices 2 and radar devices 5 may be used. In such case, a map can be formed while the two kinds of videos are simultaneously viewed. In place of the radar video 5, a video image of a TV camera may be possible, which is applicable to a general TV display.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a map creation device for a radar display device.

[Conventional technology]

FIG. 2 shows, for example, a conventional airport surface detection radar (Airpo
rt 5 surface Detection I! qu
ipment; hereinafter referred to as ASDE). In the figure, 1 is a digitizer that inputs map information, 2 is a map creation device that creates a map based on the information input from digitizer 1, 3 is a ROM writer that creates ROM for map display, and 4 is a map display device. This is a display device for confirmation.

Next, the operation will be explained. At ASDE, maps of the airport, including runways and taxiways, are superimposed on radar video and displayed on a display device. When creating a map, a map of the airport at an appropriate scale is attached to the digitizer 1, and the coordinates of the map are read.

The data is sent to the map creation device 2 to create map ROM data and simultaneously displayed on the display device 4, allowing the user to work while checking the creation status. After map data input is completed, the data is transferred from the map creation device to the ROM writer 3 to create a ROM to be used in the radar display device.

[Problem to be solved by the invention]

Since conventional map creation devices are configured as described above, the accuracy of coordinates when inputting a map is determined by the map attached to the digitizer, and in many cases, the map 8 and radar video 7 are combined as shown in Figure 4. It was out of alignment.

This invention was made to solve the problems of the conventional ones as described above, and an object thereof is to provide a map creation device that can easily input highly accurate map data.

[Means to solve the problem]

A map creation device for a radar display device according to the present invention is configured to superimpose and display a radar video in addition to a map when creating a map.

[Effect]

In this invention, since it is configured as described above, it is possible to input the map while checking it on the radar video, and it is possible to input the map without causing any deviation from the video.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure shows a map creation device for a radar display device according to an embodiment of the present invention. In the figure, the same reference numerals as in FIG. 2 indicate the same parts, 5 is a radar video, and 6 is a radar video map synthesis device.

Next, the operation will be explained. Entering map coordinates from digitizer 1 is the same, but instead of picking up the coordinates from a map like in the past, you can directly input the coordinates from the runway and taxiway on the radar video displayed on the display device. Also collect the coordinates. That is, the radar video 5 and the map display created by the map creation device 2 are inputted while checking the display synthesized by the radar video map composition device 6. The map created by this method does not deviate from the actual radar video, and it is possible to easily input a highly accurate map.

In the above embodiment, there is only one map creation device and one radar video, but there may be two or more. In this case 2
You can create a map while watching different types of videos at the same time. Third
An example of this is shown in the figure, in which la and lb are digitizers, and 2a and 2b are map creation devices.

Further, although the above embodiment relates to a map input device for a radar display device, it can also be applied to a general TV display device by using a video image of a TV camera instead of the radar video 5, for example.

〔Effect of the invention〕

As described above, according to the map creation device for a radar display device according to the present invention, a map can be input while confirming it with the radar video on the display device, so a highly accurate map can be input easily.
