Abstract

PURPOSE:To facilitate confirming the coincidence between an input screen and input data, by operating a cursor on the display screen to superpose it onto required points and measuring their two-dimensional positions and displaying measured results on the screen. CONSTITUTION:The image of a drawing 1 is picked up by a television camera 2, and a cursor 9A by which an optional part is displayed with an optional magnification on a display device 5 is put on a required position to input the position of this point on the screen, and then, the position is calculated in a computer 11 and is stored in an information processing device 12. The point of the position calculated in this manner is written in a corresponding position calculated in this manner is written in a corresponding position of a storage device 6 for overwriting and is displayed as a point or a pattern brighter than the peripheral part on the display device 5 where the drawing 1 is projected actually. The operator checks whether this displayed point is superposed correctly on the position, where it should be inputted, on the display screen or not to confirm easily a correct input. Thus, the operator confirms whether a pattern as linkage of many inputted points is inputted correctly or not.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drawing input method for smoothly and easily inputting information on drawings of any size to an information processing apparatus.

Conventionally, there are various types of voice input methods for inputting information written on a drawing into an information processing device. In the μ method used, a drawing is placed on a tapelet, and a stylus (cursor) is placed on the point on the drawing that you want to input.
The position is detected by roaring, and the information processing ILM
t, but a separate display device is required to check the input results. For this reason, the operator must change his/her body direction toward the display device each time he/she looks at the drawing on the tablet and operates the stylus (cursor), making inputting large drawings a cumbersome task. Become. Also, check whether the input drawing and displayed input data match.
Even if it is displayed as a numerical value, it is difficult to confirm it, and even if it is displayed as a figure, it is difficult to precisely confirm it, and it is not easy to eliminate errors caused by input device malfunction or operational errors.

This invention relates to a method for inputting information written on a drawing into an information processing device, in which a television camera or the like is used to take a picture of the drawing to be inputted, and the cursor is operated on the image receiving display screen. When you overlap the point you want to input, measure and input the position using the and k, and display the input points and the figure obtained by connecting them on the same screen in the form of a line drawing with different brightness and color on the real plane. When displayed over the drawing image, the operator can clearly see the difference between the actual drawing and the drawing input using the above method, allowing smooth input into the drawing information escape device. The system provides a drawing input method based on the following methods. below.

An embodiment of the present invention will be described based on the drawings.

The embodiment of the invention shown in the figure consists of the following four elements.

(1) A television camera including an optical system for photographing drawings 1v! , and a swivel S for changing the direction of the television camera 2, as well as the viewing direction of the television camera 2 and the viewing box 1!
In order to obtain the angle of view indicated by Display device 5 for overlapping display This is a storage device 6 for overwriting that stores input drawing information in the form of line drawings, etc.
, a display converter T that converts the image into an image, and a display section that displays the output of the display converter T and the image of the drawing from the television camera 2 superimposed on it.

(3) A cross-shaped cursor displayed at any position on the display device S! IA, a cursor generating unit 9 that generates the video signal, and a cursor operating unit 11B that allows the operator M to freely change the position of the cross-shaped cursor 9A.
.

(4) A synchronization control unit IJ that performs linkage and synchronization between the television camera 29 display device 5 and the cursor generation unit 9.

Note that 11 represents an electronic computer, and 12 represents an information processing device.

Next, the operation of the embodiment shown in one drawing will be explained. A drawing 1 of arbitrary size is placed in front of a television camera 2 and imaged. The operator M displays an arbitrary portion on the display device S at an arbitrary magnification by operating the optical system and the rotation device 3.

Operator M, while looking at drawing 1 displayed on one screen, operates nine cursors that are displayed on the same screen and can be moved freely, and places cursor IA at the required position. When the position of the point on the screen is input from k, the position of the input point on the drawing 1 is calculated by the computer 11 from the viewing direction and the viewing angle of the television camera 2 at that time, and the information is generated. stored within the geographic device 12;

Next, the position on the screen that should be displayed when the point at the position calculated in this way is imaged by the TV camera 2 having the current viewing direction and viewing angle is calculated and stored in one overwriting memory. It is written in the corresponding position in the device 6 and displayed as a brighter dot or figure on the display device S which actually shows the drawing 1. The operator M can easily check whether the correct input has been made by checking whether the thus displayed point correctly overlaps the desired input position on the display screen. Furthermore like this
A large number of points are input using the above operations, and a figure is input as a connection between them.However, the figure on the actual figure N1 displayed on the display device S and the figure input by the above operation overlap. Since it is displayed, you can identify any differences at a glance.
Correct drawing input is possible by correctly performing necessary supplementary input operations and input operations for correction.

As explained above, this invention allows the size, color, and shape of the drawing to be input to the information processing device to be arbitrarily selected.
Furthermore, minute descriptions can be easily input by enlarging the image using an optical system. Furthermore, since the input figures are displayed in the same figure format over the screen, rather than using numerical position data, even operators who are not trained in 4TK can input drawings in a short period of time without making mistakes, which can reduce fatigue. It has the advantage of having many extremely effective features, such as fewer
