Abstract

PURPOSE:To extremely reduce the input cost of the map information by synthesizing two map pictures processed by a picture magnification/reduction rotary shift device on the basis of the pointed contents into a single map picture through a logical arithmetic operation. CONSTITUTION:When two map pictures are inputted, a picture magnification/ reduction rotary shift device 3 applies one or more processes of magnification, rotation and shift to at least one of both map pictures to be process on the basis of the pointed contents. At the same time, a picture logical arithmetic unit 4 synthesizes those two map pictures processed by the device 3 into a single map picture based on the pointed contents. Thus it is possible to input the map information in a picture with use of the maps having different reduced scales and directions. As a result, the input cost of the map information can be extremely reduced.

(Problems to be Solved by the Invention) However, in the above-described conventional method, map information is input using a digitizer or the like, and therefore an enormous amount of time and effort is required for the input work.

In order to eliminate this inconvenience, a method of inputting maps as images has recently been proposed, but in such a method, each map must have the same scale and direction, so the image required for map input is・There was a problem that it was difficult to obtain images.

In view of the above circumstances, the present invention provides a map image synthesis device that can input map information as an image using maps of different scales and directions, thereby significantly reducing the human cost of map information. The purpose is to

The map image synthesis device shown in this figure includes an image input device 1,
Image memory devices 2a, 2b, image enlargement/reduction rotation movement device 3, image logic operation device 4, image memory device 5,
It is equipped with an image output device 6, a control device 7, and a display operation device 8, and displays a plurality of map images to be processed at the time of image composition, and in this state, an operator inputs data necessary for composition of these map images. When this data is input, these map images are combined to create one map image based on this data.

The image input device 1 includes an image scanner device and the like, and captures map information as an image and selectively supplies it to either of the image memory devices 2a and 2b.

The image memory devices 2 a s 2 b are each configured to hold an image when it is supplied from the image human power device 1 or the image scaling/rotating device 3 , and are held under the control of the control device 7 . An image of what is happening.

The image enlargement/reduction/rotation device 3 or the image logic operation device 4
, is supplied to the control device 7.

The image enlarging/reducing/rotating/moving device 3 is configured to selectively read out images from each of the image memory devices 2a12b under the control of the control device 7, and enlarge, reduce, rotate, or move the images. The processed image is stored in the original image memory device.

Under the control of the control device 7, the image logic operation device 4 reads images from each of the image memory devices 2as2b, performs logical operations on them, synthesizes one map image, and supplies this to the image memory device 5.

The image memory device 5 is configured to hold an image when it is supplied from the image logic operation device 4,
The image held under the control of the control device 7 is outputted to the outside via the image output device 6.

The display operation device 8 is equipped with a CRT, a mouse device, a keyboard, etc., and when an image is supplied from the control device 7, it is displayed on the screen, and data input from the mouse device or keyboard is displayed on the screen. It is also supplied to the control device 7.

The control device 7 includes a CPU and the like, and controls the entire map image synthesis device.

Next, the operation of this embodiment will be explained with reference to FIGS. 2 to 4.

First, when one map image as shown in FIG. 2 and a map image 20 as shown in FIG. 3 are inputted via the image input device 1, one of them is stored in the image memory device 2a, and the other is The image data is supplied to and held in the image memory device 2b.

Is it necessary to combine these map information after this?

If so, the control device 7 reads out each map image 19, 20 from each image memory device 2a, 2b and displays them on the display/operation device 8 one after another.

Based on these displays, the operator selects the same part of each of these map images, for example, building 2 in map image 19.
3 points a and b, and point α of the building 23 in the map image 20,
If β is specified using a mouse device, the control device 7
Based on these instructions, the magnification factor γ, rotation angle θ, and movement distance mxSmy necessary to match the scale and direction of these map images are determined.

In this case, the magnification rate γ is obtained, for example, by the calculation shown in the following equation.

However, Xal, Yal: XY coordinate values Xa2, Ya of point a
2: XY coordinate values of point Xbl, Ybl: XY coordinate values of point α Xb2, Yb2: XY coordinate values of point β Also, the rotation angle θ is one vector (ΔXa).

ΔYa) and the other vector (Δxb, Δyb).

Also, the moving distance m in the X direction x the moving distance m in the SY direction
y is obtained by the calculation shown in the following equation.

Next, the control device 7 transmits these enlargement ratio γ, rotation angle θ, and movement distances mx, my to the image enlargement/reduction rotation movement device 3.
supply to.

As a result, the image enlargement/contraction rotation and movement device 3 rotates the map image 20 stored in the image memory device 2b at the rotation angle θ around the point α, enlarges it at the enlargement rate γ, and then The object is moved by a distance mx in the direction and by a distance my in the Y direction.

Thereafter, the control device 7 reads each of the map images 19 and 20 stored in the image memory devices 2a and 2b and displays them on the display and operation device 8 in a superimposed manner.

Here, if the operator operates the display/operation device 8 and inputs the boundary data of each of the map images 19 and 20 and the processing method for the overlapping portions, the control device 7 will process the image logic according to the contents of this instruction. A logical operation instruction is issued to the arithmetic unit 4.

The image logic operation device 4 uses the map images 19 and 20 stored in the image memory devices 2a and 2b according to the contents of this instruction.
extraction processing, bit-wise logical operation processing (for example,
AND processing, OR processing, processing for selecting one of the map images, etc. are performed to synthesize a map image 26 as shown in FIG. 4, and this is supplied to the image memory device 5.

In this case, the map image 26 is created by a process in which the area 27a selects only the map image 19, a process in which the area 27a selects only the map image 20, and a bit synthesis process in the area 28.

Then, the map image 26 obtained through such composition processing is outputted to the outside via the image output device 6.

Thus, in this embodiment, each map image 19.2
Even if the 0 scales and directions are different, it is now possible to combine them to create a single map image, so you can input map information as an image using maps with different scales and directions. This can significantly reduce the cost of inputting map information.
