  The joysticks 25 and 25 ′ are arranged in the vicinity of the housing 20.

In order to use this telescope system, the objective lenses 32 and 32 ′ of the two telescopes 3 and 3 ′ must be directed to the same observation object S with respect to the observation target S.
For this purpose, the observer first determines or measures an approximate distance to the observation object S, and appropriately determines the distance between the telescopes 3 and 3 ′, that is, the distance between the telescopes 3 and 3 ′ according to the distance. The adjustment of the distance between the telescopes 3 and 3 ′, that is, the adjustment of the distance between the mounts 7 and 7 ′ is performed by operating the left and right joysticks 25 and 25 ′.

  Next, the left joystick 25 is operated to adjust the azimuth and altitude of the telescope 3 so that the left telescope 3 collimates the observation object S, and to focus.

  Thereafter, the right joystick 25 ′ is operated to adjust the azimuth and altitude of the telescope 3 ′ so that the right telescope 3 ′ collimates the observation object S and to focus.

  As a result, the left and right telescopes 3, 3 ′ collimate the same observation object S.

  The images formed by the objective lenses 32 and 32 'are picked up by the image pickup devices 5 and 5', and the image signals are stored in the storage device 12 through the cables 17 and 17 'as image information.

  The liquid crystal displays 13 and 13 ′ display video based on the image signal from the storage device 12. The images displayed on the liquid crystal displays 13 and 13 ′ are enlarged by the eyepieces 15 and 15 ′ and observed by an observer. At this time, the image on the left liquid crystal display 15 enters the left eye for the observer, the image on the right liquid crystal display 15 ′ enters the right eye for the observer, and the left and right images are synthesized in the head and viewed as a three-dimensional image. .

  In addition to the above collimation methods, the following collimation methods are also conceivable.

  With the front surface 9a (see FIG. 1) of the rail 9 facing the observation object S, the azimuth and altitude of the telescope 3 are adjusted to the observation object S and the observation object S is focused. At this time, the focus distance changes according to the distance to the observation object S, but the image sensor 5 moves relative to the objective lens 32 according to the focus distance. If the distance between the objective lens 32 and the image sensor 5 is known, the distance to the observation object S can be known. If the distance to the observation object S is known, the azimuth to be collimated of the objective lens 32 ′ of the other telescope 3 ′ can be known, so that the azimuth of the telescope 3 ′ can be automatically corrected by a control device (not shown). it can. The altitude of the telescope 3 ′ at this time is made equal to the altitude of the telescope 3.

  In the case of this collimation direction, collimation can be performed with higher accuracy by using a distance measuring device that measures the distance to the observation object S.

  In addition to the above collimation methods, the following collimation methods are also conceivable.

  In a tourist destination telescope system, the number of observation objects S to be viewed is limited. Therefore, the distances from the telescope system to a plurality of observation objects S are measured in advance and stored in the memory of the control device of the gantry 3, 3 ′. Keep it.

  When the observer points the telescope 3, 3 ′ toward the observation object S, the observer determines that he / she sees the observation object S, and observes the observation object S from the direction of the telescope 3, 3 ′. And automatically adjusts the azimuth and altitude of the telescopes 3 and 3 'and the distance between the telescopes 3 and 3' according to the distance to the observation object S stored in the memory of the control device in advance. Thus, the collimation of the telescopes 3 and 3 ′ can be automatically performed. In this case, it is possible to operate two telescopes with one joystick.

  As described above, even if the telescopes 3 and 3 'are collimated correctly, the images of the left and right imaging elements 5 and 5' may be displaced due to the backlash of the gantry 3 and 3 '. In this case, the image shift can be corrected as follows.

  The correction device 19 analyzes the coordinate information of the same characteristic part of the images of the left and right imaging elements 5 and 5 ′, and detects the deviation of the characteristic part of the left and right images. When a deviation between the characteristic portions of the left and right images is detected, the liquid crystal display 13 is corrected by moving one image by the amount of the deviation (for example, measuring how many pixels) and adjusting it to the other image. , 13 '.

  The first and second rotary drive devices 71, 71 ′, 72, 72 ′ have a rotor encoder, and the front side 9 a of the rail 9 is directly opposed to the observation object S by the rotary drive device 101 of the swivel base 10. Therefore, based on the angle of the rotary encoder (azimuth of the telescopes 3 and 3 '), the distance to the observation object S can be measured using a triangulation method. Further, as described above, the distance from the distance between the image sensor 5 and the objective lens 32 to the observation object S can also be measured. As described above, when the distance to the observation object S can be measured, the distance between the telescopes 3 and 3 ′ in the longitudinal direction of the rail 9 may be automatically adjusted according to the distance of the observation object S.

  According to this embodiment, since the telescopes 3 and 3 ′ are spaced apart from each other, even a distant observation object S can be viewed stereoscopically.

  Moreover, since the rail 9 which supports the mount frame 7 and 7 'is installed in the turning mount frame 10, all directions can be observed.

  FIG. 4 is a conceptual diagram showing the front of a telescope system according to a second embodiment of the present invention.

  Portions common to the first embodiment are denoted by the same reference numerals and description thereof is omitted. Only the main differences will be described below.

  Imaging elements 5 and 5 ′ (see FIG. 3) disposed in the telescopes 3 and 3 ′ are connected to a stereoscopic image composition device (stereoscopic image composition unit) 227 via cables 226 and 226 ′.

  The stereoscopic image synthesizing device 227 is connected to the stereoscopic image display device 229 via an information synthesizing device (information synthesizing means) 230 by a cable 228.

  The stereoscopic image display device 229 includes a liquid crystal display 229a and a wrench killer lens 229b. The lenticular lens 229b is disposed on the image display surface of the liquid crystal display 229a.

  In the stereoscopic image synthesizing device 227, the images obtained by the imaging elements 5 and 5 ′ are finely divided into stripes, and the divided images are connected to form one image aggregate. Then, the stereoscopic image synthesizing apparatus synthesizes a stereoscopic image by alternately arranging an image aggregate obtained from the image of the image sensor 5 and an image aggregate obtained from the image of the image sensor 5 ′. This stereoscopic image is displayed on the liquid crystal display 229a. The stereoscopic image displayed on the liquid crystal display 229a is observed by the observer through the lenticular lens 229b, so that the image aggregate obtained from the image of the image sensor 5 is observed with the left eye, and the image of the image sensor 5 'is observed with the right eye. The image aggregate obtained in is observed. As a result, the stereoscopic image is stereoscopically viewed.

  In this embodiment, since the information synthesizing device 230 is provided, it is possible to synthesize character information and image information data input from an input device (not shown) into a stereoscopic image. Furthermore, if the information synthesizing device 230 is connected to a personal computer, character information and image information data obtained from the Internet can be synthesized into a stereoscopic image.

However, in the third embodiment, as shown in FIGS. 5 and 6, the objective lens 32, the image displayed on the liquid crystal display 13, 13 ′ is viewed through the eyepiece 15, 15 ′. The optical image obtained by 32 ′ is transmitted to the eyepiece lenses 315 and 315 ′ disposed in the housing 320 via the optical fibers 331 and 331 ′, and can be enlarged and observed by the eyepiece lenses 315 and 315 ′.

The telescope 403 is supported on a gantry (not shown) so that its azimuth and altitude can be adjusted. This mount does not have a traveling device and is fixed to the floor of the rooftop 402a. Therefore, in the case of the fourth embodiment, the distance between the telescopes 403 cannot be adjusted. However, since the telescopes 403 are sufficiently separated from each other, there is no particular problem even if the distance between the telescopes 403 cannot be adjusted.

  The fourth embodiment has the same effects as the first embodiment.

  In the above-described embodiment, the telescopes 3, 3 ′ and 403 are arranged at the same height from the ground, but the telescopes are arranged at different heights with respect to the telescopes 3, 3 ′ and 403. If so, stereoscopic viewing in the vertical direction is also possible.

  In the above-described embodiment, the liquid crystal displays 13 and 13 'are used as the display device, but the display device is not limited to the liquid crystal display.

  Note that the liquid crystal display 229b with the lenticular lens 229b is used as the stereoscopic image display device, but the stereoscopic image display device is not limited to the liquid crystal display 229b with the lenticular lens 229b.

  In the above-described embodiment, the joysticks 25 and 25 ′ are used as the pointing device. However, the pointing device is not limited to the joysticks 25 and 25 ′, and for example, a keyboard, a mouse, or the like may be used.
