Embodiment 1

[0019] Embodiment 1: as figure 1 As shown, the device for two-way photography is a coaxial two-way photography device, which can take pictures of the target images on both sides on the same optical axis, including a casing 1, a first window 2, a second window 3, and an imaging window 4. The reflective surface makes the one-way mirror 5 of the camera window 3 after reflecting the light coming in from the first window 2, and changes the light path of the light entering from the second window 3 to make it pass through the one-way mirror from the light-transmitting surface of the one-way mirror. Enter the mirror array of the camera window 4 behind the perspective mirror 5; Controllable shading devices are respectively provided. There is a shading device 6 in the first window 2, and a shading device 61 in the second window 3, and the shading device is a conventional shading device.

[0020] The one-way mirror has a reflective surface 51 and a transparent surface 52 .

Embodiment 2

[0027] Embodiment 2: as figure 2 As shown, the characteristics of this embodiment are: it is a parallel-axis two-way photography device, which can take pictures of the target images on both sides of the parallel optical axis, the positions of the first window 2 and the second window 3 are staggered from each other, and the mirror array is one side Plane reflecting mirror 10, this mirror slope faces the second window 3, and the angle between this mirror and the optical axis of the light entering from the second window 3 is 45 °, and the mirror slope faces the light-transmitting surface of the one-way mirror 5, and the one-way mirror The included angle to perspective mirror 5 is 90°. All the other are with embodiment 1. Its principle is the same as embodiment 1.

[0028] This embodiment has a simple structure and less plane mirrors, which can save costs.

Embodiment 3

[0029] Embodiment 3: the characteristics of this embodiment are: described camera window 4 is perpendicular to first window 2, second window 3, and first window 2, second window 3 are on both sides of the plane where camera window 4 is located; 2. The positions of the second windows 3 are staggered from each other. The optical axis between the one-way mirror 5 and the light entering the first window is 45°, and the slope of its reflective surface faces the first window and the camera window. All the other are with embodiment 1. Its principle is the same as embodiment 1.

[0030] The device for two-way photography of the present invention uses mirror arrays and one-way perspective mirrors to shoot light paths in different directions to the same camera window, thereby realizing two-way photography, so that one camera station can take pictures of images in two opposite directions, saving a lot of time and money. cost. The present invention can also realize coaxial two-way phot...

Abstract

The invention discloses a bidirectional shooting device, which is characterized by comprising a shell, a first window, a second window, a shooting window, a one-way photoscope and a mirror array, wherein the one-way photoscope is used for reflecting light entering from the first window onto the shooting window by using the reflective panel of the one-way photoscope; the mirror array is used for changing the light path of light entering from the second window so as to make the light pass through the one-way photoscope from the illuminating surface of the one-way photoscope and enter the shooting window; the first window and the second window are parallel with each other; the shooting window is positioned between the first window and the second window; and the first window and the second window are provided with a controllable shading device respectively. By the bidirectional shooting device, bidirectional shooting is realized, two images in opposite directions can be shot by one shooting platform, cost is saved, coaxial bidirectional shooting can be realized, target images on the same straight line on both sides can be shot by a single camera, and optical axis superposition accuracy is high.

Description

technical field [0001] The invention relates to a two-way photography device, which is a two-way photography device. Background technique [0002] In the prior art, when performing coaxial two-way camera, two cameras with optical lenses are used and fixed together back to back. This kind of two-way camera device is composed of two cameras, and the cost is high, and the coaxial precision of the optical axes of the two cameras cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a two-way photography device, which can realize two-way photography with only one camera, and has low cost. [0004] The technical solution problem of the present invention can be by taking following technical scheme: [0005] The device for two-way photography is characterized in that it includes a housing, a first window, a second window, and a camera window, and uses its own reflective surface to reflect the light comi...
