Description

Technical Field

[0001] The utility model relates to the technical field of camera lenses, in particular to a binocular lens with single optical path output. Background Art

[0002] A camera is an optical instrument that forms and records images using the principle of optical imaging. A surveillance camera is a type of camera, and there are many types of surveillance cameras. Different functions of cameras should be selected to meet different surveillance requirements. In the application scenarios of intelligent surveillance in rail transit and intelligent surveillance in road traffic, in order to save costs, facilitate installation and maintenance, the surveillance range of a single camera should be as large as possible; in order to enable intelligent algorithms to identify tiny foreign object intrusions in key areas such as tracks or roads, the resolution of key areas should be as high as possible.

[0003] The prior art mainly realizes large-range surveillance through wide-angle cameras, pan-tilt cameras or multi-camera cameras. When a wide-angle camera captures a large-range scene, it is prone to image distortion. In particular, stretching or distortion may occur in the edge part. This kind of distortion not only affects the visual effect, but may also further reduce the resolution and clarity of the image. The pan-tilt camera relies on rotation to image different areas multiple times to achieve large-range surveillance, but it cannot achieve large-range real-time surveillance. Moreover, the pan-tilt camera realizes the rotation and tilting of the camera through its internal mechanical structure. These mechanical structures may be affected by problems such as wear, looseness or deformation during long-term operation, resulting in an increase in the camera failure rate. For multi-camera cameras, due to the integration of multiple cameras and multiple sets of image processing hardware, their manufacturing cost is significantly higher than that of single-camera cameras, and their volume is larger and the structure is more complex. And because the two image sensors are installed through mechanical structures, there must be a deviation in the image center points, so the surveillance effect of large-range surveillance is reduced. Summary of the Utility Model

[0004] In order to improve the surveillance effect of large-range surveillance, the utility model provides a binocular lens with single optical path output.

[0005] A binocular lens with single optical path output provided by this application adopts the following technical solutions:

[0006] A binocular lens with single optical path output includes a first eye lens, a second eye lens and an image source selection and synthesis module. Both the first eye lens and the second eye lens are connected to the image source selection and synthesis module. A shutter control module is provided on the image source selection and synthesis module. The shutter control module is used to control the opening and closing of the shutter in the first eye lens or the second eye lens. A main control input interface for connecting to an image processing component is also provided on the shutter control module. An output interface for connecting to an external camera is provided on the image source selection and synthesis module.

[0007] By adopting the above technical solution, the binocular lens is connected to the camera through the output interface. The first eye lens and the second eye lens respectively monitor two different continuous or discontinuous areas. When it is necessary to monitor the imaging area of the first eye lens, the shutter control module controls the shutter in the first eye lens to open and the shutter in the second eye lens to close. The light passes through the first eye lens and the image source selection and synthesis module and then reaches the image processing component for imaging. When it is necessary to monitor the imaging area of the second eye lens, the shutter control module controls the shutter in the first eye lens to close and the shutter in the second eye lens to open. The light passes through the second eye lens and the image source selection and synthesis module and then reaches the image processing component for imaging. In this way, the camera can be equipped with one image sensor and one set of image processing hardware to image two different continuous or discontinuous areas, reducing the cost, simplifying the structure, and not having the image center point deviation of multiple pictures, thereby improving the monitoring effect of large-range monitoring.

[0008] Optionally, the first eye lens is rotatably connected to one end of the image source selection and synthesis module through a first rotating connection component, and the rotation center line of the first eye lens is perpendicular to the center line of the first eye lens; the second eye lens is rotatably connected to the other end of the image source selection and synthesis module through a second rotating connection component, and the rotation center line of the second eye lens is perpendicular to the center line of the second eye lens.

[0009] By adopting the above technical solution, the first eye lens and the second eye lens are separately installed from the image source selection and synthesis module. The first eye lens is connected to one end of the image source selection and synthesis module, and the second eye lens is connected to the other end of the image source selection and synthesis module. At this time, the first eye lens and the second eye lens can rotate at any angle around the image source selection and synthesis module as the axis. After rotating to the required angle, the first eye lens and the second eye lens are positioned so that the first eye lens and the second eye lens form an included angle as needed, and two different continuous or discontinuous areas can be respectively monitored, thereby improving the monitoring effect of large-range monitoring.

[0013] A first locking knob, the first locking knob is threadedly connected to the first eye lens. When locked, the inner end of the first locking knob vertically abuts against the first snap ring.

[0014] By adopting the above technical solution, the first objective lens is inserted into one end of the image source selection and synthesis module, so that the first snap ring is located in the first groove. The first snap ring limits the axial position of the first objective lens. At this time, the first objective lens can rotate at any angle with the image source selection and synthesis module as the axis. After rotating to the required angle, it is tightened against the first snap ring through the first locking knob, thereby realizing the installation and positioning of the first objective lens. Rotate the first objective lens to the required angle according to the needs, thus improving the monitoring effect of large-range monitoring.

[0015] Optionally, the second rotary connection assembly includes:

[0016] A second snap ring coaxially arranged at the end of the image source selection and synthesis module away from the first snap ring;

[0017] A second groove provided on the second objective lens and rotatably engaged with the second snap ring. The depth direction of the second groove extends along a line perpendicular to the midline of the second objective lens;

[0018] A second locking knob threadedly connected to the second objective lens. When locked, the inner end of the second locking knob vertically abuts against the second snap ring.

[0019] By adopting the above technical solution, the second objective lens is inserted into the other end of the image source selection and synthesis module, so that the second snap ring is located in the second groove. The second snap ring limits the axial position of the second objective lens. At this time, the second objective lens can rotate at any angle with the image source selection and synthesis module as the axis. After rotating to the required angle, it is tightened against the second snap ring through the second locking knob, thereby realizing the installation and positioning of the second objective lens. Rotate the second objective lens to the required angle based on the monitoring area of the first objective lens to achieve separate monitoring of two different areas, thus improving the monitoring effect of large-range monitoring.

[0020] Optionally, angle scales are respectively provided on the periphery of the image source selection and synthesis module near both ends, and indication marks pointing to the corresponding angle scales are provided on both the first objective lens and the second objective lens.

[0021] By adopting the above technical solution, the cooperation between the indication mark and the angle scale can facilitate the judgment of the rotation angles of the first objective lens and the second objective lens, thereby improving the convenience of rotating the first objective lens and the second objective lens.

[0022] Optionally, a first objective lens group, a first objective shutter, and a first objective refractive lens are sequentially arranged in the first objective lens along the light incident direction. The opening and closing of the first objective shutter are controlled by a shutter control module, and the shutter control module has a first control interface connected to the first objective shutter; a second objective lens group, a second objective shutter, and a second objective refractive lens are sequentially arranged in the second objective lens along the light incident direction. The opening and closing of the second objective shutter are controlled by the shutter control module, and the shutter control module further has a second control interface connected to the second objective shutter.

[0023] By adopting the above technical solution, the light in the monitoring area of the first objective lens reaches the first objective shutter after passing through the first objective lens group, and the light in the monitoring area of the second objective lens reaches the second objective shutter after passing through the second objective lens group. The area imaging is selected according to the needs. When it is necessary to monitor the imaging area of the first eyepiece, the shutter control module controls the first objective shutter to open and the second objective shutter to close. The light passes through the first objective lens group and the first objective refractive lens and then reaches the image source selection and synthesis module. When it is necessary to monitor the imaging area of the second eyepiece, the shutter control module controls the second objective shutter to open and the first objective shutter to close. The light passes through the second objective lens group and the second objective refractive lens and then reaches the image source selection and synthesis module. The light processed by the image source selection and synthesis module finally passes through the image processing component for imaging and output, so as to realize that a camera is equipped with an image sensor and a set of image processing hardware to image two continuous or discontinuous different areas, reduce the cost, simplify the structure, and there will be no deviation of the image center point of the multi-picture, thereby improving the monitoring effect of large-range monitoring.

[0024] Optionally, an eyepiece refractive lens and an eyepiece group are arranged in the image source selection and synthesis module. The eyepiece refractive lens is located between the first objective refractive lens and the second objective refractive lens. The light refracted by the first objective refractive lens enters the eyepiece refractive lens and is refracted by the eyepiece refractive lens to the eyepiece group. The light refracted by the second objective refractive lens enters the eyepiece refractive lens and is refracted by the eyepiece refractive lens to the eyepiece group.

[0025] By adopting the above technical solution, the first objective refractive lens refracts the light processed by the first objective lens to one side of the eyepiece refractive lens, and the second objective refractive lens refracts the light processed by the second objective lens to the other side of the eyepiece refractive lens.

[0026] Optionally, the eyepiece refraction lens is an equilateral right-angled triangular lens. The first eyepiece refraction lens refracts light to the surface where one of the right-angled sides of the eyepiece refraction lens is located. After being refracted by the eyepiece refraction lens, the light exits perpendicularly from the surface where the hypotenuse of the eyepiece refraction lens is located. The second eyepiece refraction lens refracts light to the surface where the other right-angled side of the eyepiece refraction lens is located. After being refracted by the eyepiece refraction lens, the light exits perpendicularly from the surface where the hypotenuse of the eyepiece refraction lens is located. The eyepiece group is parallel to the hypotenuse of the eyepiece refraction lens and is located on the extension line of the perpendicular bisector of the hypotenuse of the eyepiece refraction lens.

[0027] By adopting the above technical solution, the light refracted by the first eyepiece refraction lens and the second eyepiece refraction lens are respectively located on both sides of the eyepiece refraction lens. The eyepiece refraction lens refracts the light from two different image sources to the same imaging output channel, thereby realizing dual-image-source input and single-imaging output, reducing the cost, simplifying the structure, and not having the image center point deviation of multiple pictures, thus improving the monitoring effect of large-range monitoring.

[0028] Optionally, the output interface is a standard C interface.

[0029] By adopting the above technical solution, it can be adapted to all C-port or CS-port cameras through the standard C interface, thereby improving the convenience of using the binocular lens.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. Connect the binocular lens to the camera through the output interface. The first eyepiece lens and the second eyepiece lens respectively monitor two different continuous or discontinuous areas. When it is necessary to monitor the imaging area of the first eyepiece lens, the shutter control module controls the shutter in the first eyepiece lens to open and the shutter in the second eyepiece lens to close. The light passes through the first eyepiece lens and the image source selection and synthesis module and then reaches the image processing component for imaging. When it is necessary to monitor the imaging area of the second eyepiece lens, the shutter control module controls the shutter in the first eyepiece lens to close and the shutter in the second eyepiece lens to open. The light passes through the second eyepiece lens and the image source selection and synthesis module and then reaches the image processing component for imaging. In this way, the camera is used to image two different continuous or discontinuous areas with one image sensor and one set of image processing hardware, reducing the cost, simplifying the structure, and not having the image center point deviation of multiple pictures, thus improving the monitoring effect of large-range monitoring.

[0032] 2. The first-eye lens is separately installed from the second-eye lens and the image source selection and synthesis module. One end of the first-eye lens is connected to the image source selection and synthesis module, and the other end of the second-eye lens is connected to the image source selection and synthesis module. At this time, the first-eye lens and the second-eye lens can rotate at any angle around the image source selection and synthesis module as the axis. After rotating to the required angle, the first-eye lens and the second-eye lens are positioned so that the first-eye lens and the second-eye lens form an included angle as needed, and can respectively monitor two different continuous or discontinuous areas, thereby improving the monitoring effect of large-range monitoring.
