Abstract

PURPOSE:To smoothly move a marker and to improve measuring efficiency by permitting a first mirror to reflect observation line of sight from a stereo picture, a second mirror to lead to the reflected observation line of sight to an image forming lens part so as to form a stereo picture and narrowing or widening the interval between marker parts. CONSTITUTION:The first mirror 200 reflects the observation line 8 sight from a stereo picture, the second mirror 300 leads the observation line of sight reflected by the first mirror 200 to the image forming lens part 61 which form a stereo picture. The marker parts 21 and 22 are arranged in a direction in which a pair of image forming lens parts 61 is arrayed, and their interval is variable so that they lessen and increase the same distance. Along with the turning of a handle turning around a turning shaft in parallel with the optical axis of a coupled optical system, a driving part 23 varies the interval between the marker parts 21 and 22. Thus, dialing is performed in a direction perpendicular to the turning shaft to improve operability.

It is rotatably connected to 0.

Next, the first mirror 200 is arranged to face the pair of stereo photographs, and is used to bend the in-line line of sight from the stereo photographs in the direction of the second mirror 300. The first mirror 200 is configured to be slidable on the parabolic member 4 by an appropriate moving means. This first mirror 200 has a first pantograph 210 attached to a rotation shaft 73.
A first mirror support member 220 is formed at the diagonal of the first pantograph 210, so that the first mirror support member 220 and the first mirror 200 are always at right angles. It has become an oar to be held. Therefore, the first pantograph 210 and the first mirror support member 220 hold the nodding angle of the first mirror 200 to match the tangential direction of the parabolic member 4. Even if the first mirror 200 moves on the parabolic member 4, the inclination angle of the first mirror 200 always matches the tangential direction. Note that the direction of the first mirror support member 220 is maintained in the normal direction at the intersection of the first mirror 200 and the parabolic member 4.

The rotation shaft 74 is formed at the focal point of the parabolic member 4.

Next, the parabolic members 4, 4 are configured to draw a parabola determined according to Wi, and the first mirror 200 can be moved on this parabolic member 4.

Furthermore, the position corresponding to the focal point of this parabola is a rotation axis 74 formed in the fixed part 8. And the rail member 5 is the right cursor 21 and the left cursor? This is for moving the rod 22 in the horizontal direction.

Therefore, the right cursor 21 and the left cursor 22 are moved to the rotation axis 7.
1, the first mirror 200 is lowered along the parabolic member 4 by the telescopic arm 3. Furthermore, when the Sakichi cursors 21 and 22 approach the position of the rotation axis 71, the first mirror 200 rises along the parabolic member 4. The eyepiece section 6 corresponds to an imaging optical system, and is composed of a coupling lens section 61, a prism 62, and the like. This eyepiece section 6 can receive the light beam from the second mirror 300 and form a stereo image.

Here, based on FIG. 5, the relationship between the positions rIA of the first mirror 200 and the second mirror 300 will be explained in detail. FIG. 5(a) shows the configuration of this embodiment and Il! The optical path of the measurement line is shown in this embodiment.
It consists of 00.

Then, let the distance between the eyepiece 400 and the second mirror 300 be ζl, the distance between the second mirror and the first mirror be 02, and the distance between the first mirror and the stereo photograph be Q3. In order to keep focus adjustment, observation conditions, etc. constant regardless of the photo size, the imaging distance @0. It is necessary to keep +a2+ζ3 constant.

Therefore, as shown in FIG. 5(b), the first mirror 200
must be moved along a parabola.

That is.

It is necessary to move the first mirror 200 so as to satisfy Ll' + L2' = L1' + L2' = L1'' + L2' = L1n + L2n. Also, as the first mirror 200 moves, the second mirror 200 It is necessary to change the inclination angle of the mirror 300 and adjust the second mirror 300 to be parallel to the first mirror.

Next, one embodiment of the cursor moving section 23 will be described in detail based on FIG. 1.

A pair of feed screws 231, 231, a knob 232, and a first
pulley 233, and a pair of second pulleys 234, 234.
, the third pulley 235, the belt 236, and the tension springs 237, 237.

It consists of a pair of knobs 238, 238 and a pair of crank knobs 239, 239. Feed screw 231.2
31, both have right-hand threads with the same pitch,
A second pulley 234 is formed at the end of the feed screw 231 and 9 which are screwed into the rack 238. A first pulley 233 is connected to the knob 232, and is configured so that when the knob 232 is rotated, the first pulley 233 is rotated in synchronization with the knob 232.
corresponds to the handle, and is a third pulley 23 that rotates on a rotation axis parallel to the optical axis of the imaging optical system.
5 is formed with a rotation shaft 2351, and this rotation shaft 2351
Tension springs 237.237 are attached to the. The belt 236 then connects to the second pulley 234.
- The first pulley 233 - the second pulley and the third pulley are tensioned in this order, and when the knob 232 is rotated, the first pulley
The pulley 233 rotates, and the pair of feed screws 231, 231 also rotate due to belt transmission. for example.

When the knob 232 is rotated clockwise, the right cursor section 2
The feed screw 234 of 1(ill) rotates counterclockwise with respect to the direction in which the screw advances.
The side feed screw 234 rotates clockwise with respect to the advancing direction of the screw 9. As a result, the left and right cursor portions 21, 22
are moved by the same amount in the direction of approaching each other (in the opposite direction, the direction in which the figure enters) 9 Also, when the knob 232 is rotated counterclockwise, the direction of rotation of the feed screw E; 234, 234 is also reversed, and the left and right cursors The portions 21 and 22 move by the same amount in directions away from each other (in opposite directions). The rack 2
38 is a binion 239 connected to a crank knob 239
It is attached via 1.

Therefore, when the feed screw 234 rotates, the right cursor section 2
1 moves simultaneously with the left cursor section 22, but by rotating the crank knobs 23, the right curve section 1 21 can be moved in the lateral direction independently.

In addition, in this embodiment, the marker section 211 formed in the right cursor section 21 can be configured to be movable back and forth. This moving mechanism may also employ a mount, a pinion, a cam, or the like. Therefore, by rotating the cursor clamp knob 212 linked to the moving mechanism, the measuring point 211 can be moved forward and vertical parallax can be removed. .

It is desirable that the configuration be such that the amount of movement of the left and right cursor sections 21 and 22 can be measured. This scale can be formed not only on the racks 238 and 238 but also on the rail member 5. For example, in the above embodiment, the rack 238.2 is placed in the left Yoshi cursor portion 21.22.
38, but it is also possible to form a screw 6 in the left and right cursor portions 21 and 22 and have a straight screw pass through this screw 6.9Furthermore, in the above embodiment, a belt drive is adopted. However, chains or wires can also be used. Then, a knob 232 is attached to the oval shown in FIG.
Worm gear 2321 is installed in series.

- Threaded portions 2312 and 2313 with threads in opposite directions are formed at both ends of the feed screw 2311, and a surface gear portion 23 is formed in the center of the feed screw 2311.
14 and the worm gear 2321 can be screwed together.9 And, it is also possible to fit an illumination lamp 9 near the left and right cursor parts 21 and 22.

Next, a method of using the stereo image device 1 according to this embodiment will be explained. First, a pair of stereo photographs 100, 100 is placed at a position facing the first mirrors 200, 200.

Note that it is not limited to photographs, any stereo image is sufficient. Then, in order to match the size of this stereo photograph, the knob 232 is rotated.9 When this knob 232 is rotated, the interval between the left and right cursor sections 21.22 changes, and the distance between the left and right cursor sections 21.22 is further changed. Since the installed third telescopic arm 33.33 also moves, the first
mirrors 200, 200 move along the parabolic member 4°4. The amount of rotation of the knob 232 can be determined using the scale formed on the zigzag 238.9 After setting the left and right cursor parts 21 and 22 at appropriate positions, perform stereoscopic viewing. is reflected by the first mirror 200, 200 arranged vertically from the stereo photograph 100, 100, and further reflected by the second mirror 300, 300 enters the eyepiece 6, An image can be formed. Here, parallax can be measured by adjusting the clamp knob 239 formed on the left cursor portion 21 so that the stereoscopic measurement target becomes a scalpel mark. It becomes possible to calculate the relative height from this parallax difference.

Note that it is possible to remove the m parallax by rotating the cursor crank knob and moving the key measuring section 211 back and forth for adjustment.

Next, a case will be described in which stereo photographs 100, 100 of different sizes are used. In this case, the knob 23
2 to adjust the distance between the left and right cursor portions 21 and 22 to the scale f! formed on the rack 238. : Adjust accordingly.

As shown in FIG. 4, as the left and right cursor sections 21.22 move, the third telescoping arm 33.33 also moves horizontally, so the first mirror 200.200 is moved by the parabolic member 4.4.
move along. And the first mirror 200, 20
0 always coincides with the tangential direction of the parabola, and the second mirrors 300, 300 are also maintained parallel to the inclination of the first mirror 200°200. Furthermore, a second mirror 30
Since the rotation center of 0.300 is set at the focal point of the parabolic member 4.4, no matter which position the first mirror 200.200 moves to, its imaging distance is +L2+L.
3 remains constant. Therefore, no matter which size of the stereo photograph 100° 100 is used, the observation situation does not change.

This has the effect that readjustment is not necessary. Stereoscopic viewing of stereo photographs is a task that requires skill, but it has the outstanding effect of increasing measurement efficiency since it saves the trouble of re-setting the FI.

"Effect" In the present invention configured as described above, the first mirror reflects the observation line of sight from the stereo image, and the second mirror reflects the observation line of sight from the stereo image.
The III line of sight reflected by the mirror is guided to the imaging lens section, and this imaging lens section forms a stereo image, and the marker section is arranged in the direction in which the pair of imaging lens sections are arranged. The marker portion rotates with the rotation of the handle that rotates about a rotation axis parallel to the optical axis of the coupling optical system.
Since the marker portions are arranged so that they can approach or separate from each other by equal distances, the marker portion can be moved with the handle in a direction perpendicular to the moving direction of the marker portion. This has the outstanding effect of improving measurement efficiency by allowing the user to move the parts.
