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 methods for inputting information written on drawings into an information processing device, but the information input device and the display device for the input results are separate devices. For example, in a method using a data tablet, a drawing is placed on the tablet, and by placing a stylus (cursor) on the point on the drawing that you want to input, its position is detected and input to an information processing device. A separate display device is required to check the results. Therefore, the operator must change the orientation of his or her body toward the display device each time he or she operates the stylus (cursor) while looking at the drawing on the tablet, making inputting particularly large drawings a difficult task. In addition, it is difficult to confirm whether the input drawing and the displayed input data match even if they are displayed numerically, and even if they are displayed graphically. It was not easy to eliminate errors caused by the above error.

The present invention relates to a method for inputting information written on a drawing to an information processing device, in which the drawing to be inputted is imaged with a television camera, etc., and the cursor is operated on the image receiving display screen to input information on the drawing. Measure and input the position of the desired point by overlapping it, and create a real plan image of the input points and the shape obtained by connecting them on the same screen in the form of a line drawing with different brightness and color. A drawing input method that allows the operator to clearly recognize the difference between the actual drawing and the drawing input using the above method by displaying the drawings in an overlapping manner, allowing smooth input of drawings into the information processing device. It provides: 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 2 including an optical system for imaging Drawing 1, a rotation device 3 for changing the direction of the television camera 2, and an optical system for determining the viewing direction and viewing angle of the television camera 2. A position/angle detector 4 such as a potentiometer is attached to the system and the swivel device 3.

(2) A display device 5 that displays the captured drawing and the drawing input to the information processing device in an overlapping manner. This includes an overwriting storage device 6 that stores input drawing information in the form of line drawings, etc., a display conversion section 7 that converts the information into images, and an output of this display conversion section 7 that converts the drawing information from the television camera 2 into the drawing. It consists of a compositing section 8 that displays the image superimposed on the image.

(3) A cross-shaped cursor 9A displayed at an arbitrary position on the display device 5, a cursor generator 9 that generates the video signal, and a system for freely changing the position of the cross-shaped cursor 9A by operation of the operator M. Cursor operation section 9B.

(4) A synchronization control unit 10 that performs linkage and synchronization between the television camera 2, display device 5, and 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 the drawings 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 5 at an arbitrary magnification by operating the optical system and the rotation device 3. While looking at the drawing 1 displayed on this display screen, the operator M operates the cursor 9A that is displayed on the same screen and can be moved freely, and moves the cursor 9A to the required position.
When the position of the point on the screen is input by placing the point, the computer 11 calculates the position of the input point on the drawing 1 from the viewing direction and viewing angle of the television camera 2 at that time. and stored in the information processing device 12.

Next, the point at the position calculated in this way is the TV camera 2 that has the viewing direction and viewing angle at that time.
The position on the screen that should be displayed when the drawing 1 is captured is calculated, written to the corresponding position in the overwriting storage device 6, and displayed on the display device 5 that actually shows the drawing 1 from the surroundings. Appears as a bright dot or shape. The operator M can easily check whether the input has been made correctly by checking whether the point thus displayed is correctly overlapped with the input position on the display screen. Furthermore, a large number of points are input in this way, and a figure is input as a connection between them. The figures are displayed overlapping each other, so if there are any differences, you can identify them at a glance.
Enables correct drawing input.

As explained above, this invention allows the size, color, and shape of drawings to be input into an information processing device to be arbitrarily selected, and minute descriptions can be easily input by enlarging the image using an optical system. can. In addition, the input figures are displayed in the same figure format over the video, rather than as numerical position data, so even untrained operators can input drawings in a short time without making mistakes, which can reduce fatigue. It has the advantage of having many extremely effective features, such as fewer
