Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a visual environment evaluation experiment device in the field of visual environment evaluation technology.

Conventional configurations and their problems Conventionally, visual environment evaluation experiments have used actual lighting facilities and scaled-down models. However, in the case of actual lighting facilities, it is difficult to set lighting conditions and to set and switch experimental conditions, and
There are problems such as difficulty in maintaining a stable physiological situation, and furthermore, in the case of a reduced model, there is a problem that there is no sense of realism.

Purpose of the invention The present invention solves the above-mentioned conventional problems.
In addition to providing a three-dimensional image of the visual environment of the experiment to provide a sense of realism, the lighting conditions can be set arbitrarily, making the experimental process such as setting and switching experimental conditions, and evaluation by observers more efficient. The purpose of the present invention is to provide a visual environment evaluation experiment device.

Structure of the Invention The present invention provides a left-eye photograph and a right-eye photograph in which a portion of a lighting device is cut out from a photograph taken at the same distance as the distance between the left and right eyes, and a front view of each photograph. Visual environment evaluation with two visual environment condition setting units installed in parallel, one for the left eye and one for the right eye, consisting of lighting fixtures installed in two locations above and below, and a lighting fixture installed behind each photo. This is an experimental device, and by installing lighting equipment in two places above and below the front of the left-eye photo and two places above and below the front of the right-eye photo, the illuminance of the visual environment can be set arbitrarily. By installing a lighting fixture behind the photograph for the right eye, it is possible not only to arbitrarily set the brightness of the lighting fixture installed in the viewing environment independently of the illuminance of the viewing environment, but also by replacing the photograph. It has the advantage of being able to conduct multipurpose visual environment evaluation experiments.

In Fig. 4, 1 and 2 are two reflectors joined at a 90 degree angle, and 5 is a left eye visual environment condition setting section and a right eye visual environment condition setting section through the two reflectors. 12 is a lighting device installed behind the light-shielding plate, 19 is an installation part for the left eye visual environment condition setting unit, and 20 is a right eye viewing unit. Installation section of environmental condition setting section, 2
1 is the observer's position, and 22 is the observer's chair.

The operation of the visual environment evaluation experiment apparatus of this embodiment shown in FIGS. 1, 2, 3, and 4 will be described below.

The left eye visual environment condition setting section and the third
In the right eye visual environment setting section shown in the figure, the left eye photograph 7 and the right eye photograph 13 are By adjusting the brightness of the photo, the illuminance of the viewing environment can be arbitrarily set, and the lighting devices in the left-eye photo and right-eye photo are cut out using the lighting devices 12 and 18 installed behind the light-shielding plate. Ivy parts 9 and 14
The left eye visual environment condition setting section 3 and the right eye visual environment condition setting section 4 shown in FIG.
is presented to both eyes 6 of the observer (observer 21 in FIG. 4) through the two reflecting mirrors 1 and 2 and further through the eyepiece 5.

As described above, according to this embodiment, a three-dimensional image with a sense of realism can be obtained, and lighting equipment is provided at two locations above and below the front of the photo for the left eye and at two locations above and below the front of the photo for the right eye. The illuminance of the viewing environment can be set arbitrarily by adjusting the brightness of the photo for the left eye and the photo for the right eye. By arbitrarily setting the brightness of the cut-out portion of the lighting fixture, you can not only arbitrarily set the brightness of the lighting fixture installed in the viewing environment independently of the illuminance of the viewing environment, but also replace the photo. This has the effect that it is possible to carry out a multipurpose visual environment evaluation experiment.

Effects of the Invention The visual environment evaluation experiment device of the present invention provides a photograph for the left eye and a photograph for the right eye, in which a portion of the lighting equipment is cut out from a photograph taken at the same distance as the distance between the left eye and the right eye. By having lighting fixtures installed in two places above and below the front of each photo, and a lighting fixture installed at the back of each photo, problems in conventional visual environment evaluation experiments are solved, and the result is more realistic than conventional reduced models. This allows you to obtain the same evaluation as in an actual lighting facility, and in addition, compared to an actual lighting facility, the lighting conditions can be set arbitrarily, making experiments such as setting and switching of experimental conditions, and evaluation by observers easier. The present invention has the effect of providing a visual environment evaluation experiment device that improves the efficiency of the process, and has great practical effects.
