Problems solved by technology

[0011] However, the technique of Patent Document 1 has the following disadvantages: the image processing device includes an imaging unit and a display unit, and if the user of the image processing device does not refer to the image displayed by the image processing device, it is impossible to measure the subject (measuring object). )length
In addition, if the portability of the image processing device is to be improved, the display unit for displaying the image becomes smaller, and since the object or the scale image (scale image) of the displayed image is displayed smaller than the actual size, there is also a problem that it cannot be quickly and reliably processed. Disadvantages of accurately determining the correct length
[0012] In addition, in the technology of Patent Document 2, although it is possible to project light spots with the same pitch size, there are disadvantages such as the inability to measure the length of an object.
[0013] In this way, in the prior art, there is a disadvantage that the measurer cannot quickly and reliably measure the size of the object to be measured.

no. 1 Embodiment approach

[0059]

[0060] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is a schematic diagram showing an outline of the functions of the mobile phone device 1 (projector device) according to the first embodiment of the present invention.

[0061] This figure shows that the mobile phone device 1 can project an image within the range P1 by the projector function included in the device itself. In addition, this figure shows the case where the scale image M1 is projected by the mobile phone device 1 and the scale image M1 is projected on the object to be measured A1 which is the projection target.

[0062] In this way, the size of the object to be measured A1 can be easily measured based on the scale image M1 projected from the mobile phone device 1 .

no. 2 Embodiment approach

[0117] Hereinafter, a second embodiment of the present invention will be described in detail with reference to the drawings. The mobile phone device 2 of the present embodiment has a function of moving or rotating the scale image in parallel, in addition to the functions of the mobile phone device 1 of the first embodiment. Furthermore, the mobile phone device 2 has a function of detecting brightness and specifying the brightness of the scale image based on the detected brightness.

[0118] In addition, in this embodiment, the function of rotating the scale image is described, but the function of moving the scale image in parallel may also be used, and the mobile phone device 2 may have both functions of rotating and moving in parallel. In addition, the appearance of the mobile phone device 2 is different from the appearance of the mobile phone device 1 ( Figure 2A , B) are the same.

no. 3 Embodiment approach

[0165] Hereinafter, a third embodiment of the present invention will be described in detail with reference to the drawings. The mobile phone device 3 of the present embodiment has an imaging function, and based on the image information of the imaged image, specifies the measurement range of the projected scale image and the color information of the scale image.

[0166] In addition, the appearance of the mobile phone device 3 is different from the appearance of the mobile phone device 1 ( Figure 2A , B) are the same.

[0167]

[0168] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Figure 9 It is a schematic diagram showing the outline of the functions of the mobile phone device 3 according to the third embodiment of the present invention.

[0169] This figure shows that the mobile phone device 3 can use the projector function of its own device in the same range P1 as the first embodiment ( figure 1 ) to projec...

Abstract

Disclosed is a projection device for projecting an image, provided with: a distance detector that detects the distance between the projection device and an object to be measured, onto which the image is projected; and an image projecting part that projects an image of an actual-size scale onto the object to be measured.

Description

technical field [0001] The invention relates to a projection device, a method for controlling the projection device, and a control program for the projection device. [0002] this application claims priority based on Japanese Patent Application No. 2008-286715 for which it applied to Japan on November 07, 2008, and uses the content here. Background technique [0003] In recent years, along with the development of measurement technology utilizing information technology, a technology for electronically performing measurement using a ruler and a protractor has been developed. [0004] Patent Document 1 discloses an image processing device having a display unit for displaying an image, and an image synthesis unit for specifying a position on the image displayed on the display unit based on the image captured on the image. The three-dimensional position information of the subject (measurement object) generates a scale image (scale image) substantially representing the actual siz...
