Abstract

PURPOSE:To input a three-dimensional shape directly as interactive mode by inputting three-dimensional substance shape data directly to a computer and converting the input data into perspective and projection data on the basis of optical properties to display the data on a screen. CONSTITUTION:A detector designates the horizontal positions X, Y of an environmental model stored in a storage device 3 and the height Z from the ground surface through an designating device 1. The designated values X, Y, Z are displayed as designation values 11, 12 on a screen 10. While observing the screen, the detector inputs data X, Y, Z through the designating device 1 and moves the pattern 11-13 on the screen. Writing of a segment 13 in the environmental model through a corrector 4 means the storage of the constitutional elements of the substance. Thus, the shape of the substance 14 can be designated by repeating similar operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a device for interactively indicating the shape of an object appearing in an image.

[Background of the invention]

The technology to extract a target object from the screen is a fundamental issue in image processing. 2. Description of the Related Art Conventionally, devices that give instructions to cut out objects interactively with captured images have been incorporated into various image processing devices. However, in conventional pointing devices, the pointing point is input in terms of a coordinate system fixed on the screen, so various complicated processes are required to detect a three-dimensional object.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an instruction device that allows direct and interactive input of the three-dimensional shape of an object.

[Summary of the invention]

The key point of the present invention is to make full use of the excellent spatial perceptual ability of humans. That is, the detector of the present invention directly inputs three-dimensional object shape data into a computer, and the input data is subjected to perspective and projection transformation based on the properties of the optical system and displayed on the 11 screen.

That is, in the present invention, the computer only handles three-dimensional data processing and three-dimensional to two-dimensional conversion, and the detector performs perceptual conversion from two-dimensional to three-dimensional.

[Embodiments of the invention]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the apparatus of the present invention, in which 1 is an indicator, 2 is a display, and 3 is a memory.

4 is a corrector, 5 is a TV camera, and 6 is an image receiver.

The detector indicates the horizontal position @X, Y and height Z from the ground of the environment model stored in the memory 3 through the indicator 1. The indicated values (X, Y, Z) are displayed as shown in FIG. 2, for example. In this figure, 10 is the screen, 11
．． 12 is an instruction value. In this example, the horizontal position (x, y
) is drawn, and the base point 12 is drawn corresponding to the point (X, Y, Z)
is drawn as a designated point 12. In this example, a line segment 13 connecting the base point 12 and the indicated point 11 is also displayed.

Application examples of the indicating device of the present invention are shown in FIGS. 3 and 4. In these figures, the shape of an unknown object 14 appearing on the screen 10 is detected. FIG. 3 shows the initial state of detection.

Looking at this screen, the detector reads the data (x
, y, z) and move the figure 1t: 12.13 within the screen. Then, when the state shown in FIG. 4 is reached, the line segment 13 is written in the environment model through the corrector 4, so that the constituent elements of the object 14 are memorized. By repeating similar operations, the shape of the object 14 can be specified.

FIG. 5 shows another embodiment of the device of the invention. In addition to the configuration of the embodiment shown in FIG. 1, this embodiment has a memory 7 storing shape data and a shape indicator 8.

In this embodiment, three-dimensional shape data is selected from the memory 7 by operating the indicator 8 and drawn on the screen 10 according to the output of the indicator 1. An example of drawing is shown in FIG. 21 in this figure is the projection result of the object selected by the memory 7. Even when this embodiment is used, it is possible to specify an object similar to that of the embodiment shown in FIG.

〔Effect of the invention〕

According to the present invention, it is possible to interactively indicate the shape of an unknown object from an image.
