Description
Technical Field
The embodiment of the invention relates to the technical field of optical imaging, in particular to a synchronous shooting device and a synchronous shooting method.
Background
Synchronous shooting refers to simultaneous image shooting of the same object by using a plurality of cameras. By image-compositing a plurality of images taken simultaneously, an image satisfying the demand can be obtained. For example, in some observation experiments for a specific object, the observation object is synchronously image-acquired with different types of cameras, and then analyzed based on the synthetic image.
In the prior art, when different cameras are used for synchronously shooting the same object, the same position is usually adopted, and the camera is changed, however, in the process of manually changing the cameras, the positions of the different cameras cannot be strictly kept consistent, so that the optical path transmission is different in the imaging process, and shooting errors are generated; moreover, the camera is continuously changed manually, so that the efficiency of the synchronous shooting process is low and time is wasted.
In order to solve the above-mentioned problem, an improvement in the prior art is to fix two cameras on an adjustable bracket for synchronous shooting, however, because the positions of the two cameras on the bracket are still not uniform, the error of synchronous shooting is still larger.

Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a schematic structural diagram of a synchronous shooting device according to an embodiment of the present invention, where the embodiment is applicable to a case of synchronously shooting the same object, so as to obtain at least two images of the object at the same time. The device can be used as a stand-alone shooting device, and can also be integrated into other devices as an accessory device.
It should be noted that, other parts of the synchronous shooting device, such as an internal circuit connection component, a power supply control component, etc., are not limited in any way, and may be implemented by components in the prior art, and therefore these parts are omitted and are not shown in fig. 1.
As shown in fig. 1, the synchronous shooting device provided by the embodiment of the present invention may include a lens 101, a secondary imaging unit 102, a light splitting unit 103, and at least two image sensors 104, which are specifically explained as follows:
the lens 101 is used for initially imaging a target object, namely, the target object is imaged on an image space focal plane of the lens 101, the lens 101 comprises an adjustable zoom lens, and the target object refers to any object to be photographed currently.
The secondary imaging unit 102 is configured to receive the light beam emitted from the lens 101, and perform secondary imaging on the target object, that is, re-image the image formed on the image focal plane of the lens 101 on the image focal plane corresponding to the secondary imaging unit 102. The secondary imaging unit 102 includes at least one group of focusing lenses (including but not limited to convex lenses), the secondary imaging unit 102 is coaxial with the lens 101, and the number of focusing lens groups specifically included in the secondary imaging unit 102 is not particularly limited in this embodiment, and on the basis of ensuring that secondary imaging of the target object can be achieved, a designer can reasonably set according to requirements. In this embodiment, by setting the secondary imaging unit 102, the flange distance of the lens 101 (i.e. the flange focal length of the lens) can be equivalently extended, so that the problem that the light splitting cannot be realized by adding the light splitting unit 103 in the optical path because the original flange distance of the lens 101 is shorter is solved, when the flange distance of the lens 101 is equivalently extended, light splitting can be performed between the final imaging plane and the lens 101, which is equivalent to the requirement that the setting of the secondary imaging unit 102 is to realize light splitting by using the light splitting unit 103.
The number of focusing lens groups included in the secondary imaging unit 102 is not particularly limited, but the combined mounting between the focusing lens groups needs to satisfy a certain constraint condition to ensure the imaging quality of the target object. Specifically, each focusing lens group is coaxial, and, in the first group of focusing lenses installed behind the lens 101 along the light transmission direction, the object-side focal plane of the focusing lens close to the lens 101 coincides with the image-side focal plane of the lens 101; in the last group of focusing lenses installed behind the lens 101 along the light transmission direction, the image-side focal plane of the focusing lens near the spectroscopic unit 103 coincides with the imaging plane of the image sensor 104. Also, the focal length of the focusing lens on the side far from the lens 101 in each group of focusing lenses may be larger than that of the focusing lens on the side close to the lens 101 to ensure the effectiveness of the flange distance extension of the lens 101.
The beam splitting unit 103 is installed between the secondary imaging unit 102 and the at least two image sensors 104, and is used for splitting the light beam passing through the secondary imaging unit 102 into at least two sub-light beams, and the number of the sub-light beams is related to the number of images which need to be synchronously acquired currently. The spectroscopic unit 103 may be implemented using any optical device or combination of optical devices having a spectroscopic effect, for example, a spectroscope, a grating, or the like, and, illustratively, when the spectroscopic unit 103 is a spectroscope, the light beam passing through the secondary imaging unit 102 may be split into two sub-light beams. Before each sub-beam emitted from the light splitting unit is focused on the image plane of the image sensor, the same optical phase is maintained, and if phase difference occurs between different sub-beams due to the difference of the light splitting units, the phase compensation can be performed by setting the phase compensation unit so as to ensure that the optical phases of the sub-beams are consistent in the transmission process. The optical phases are consistent, and each image sensor can be equivalent to one sensor in the image acquisition process.
At least two image sensors 104, which are used for respectively receiving the sub-beams sent by the beam splitting unit 103 and synchronously collecting the images of the target object. Wherein one image sensor 104 receives one sub-beam, the number of the image sensors 104 can be set according to the requirement of synchronous imaging, and the image sensors 104 comprise at least two sensors capable of generating different image shooting effects, such as image sensors with different shutter speeds, and the like.
On the basis of the technical scheme, optionally, each group of focusing lenses comprises two achromatic double cemented lenses. The achromatic double-cemented lens can effectively eliminate aberration and improve imaging quality.
Optionally, the apparatus further includes a connection unit installed between adjacent components among the lens 101, the secondary imaging unit 102, the light splitting unit 103, and the at least two image sensors 104, for connecting the adjacent components. The connection unit may be implemented by reasonably adopting a structure in the prior art according to the connection condition between the components, for example, when the focusing lens in the secondary imaging unit 102 is installed, connection between the focusing lens and the different components may be implemented by using a connection ring.
Further, the device further comprises a housing for at least encapsulating the secondary imaging unit 102 and the spectroscopic unit 103, and protecting the components.
Fig. 2 illustrates an optical path in the synchronous photographing device of the present embodiment by taking an example in which the secondary imaging unit 102 includes a set of focusing lenses (e.g., two achromatic double cemented lenses), the beam splitting unit 103 is a beam splitter, and the image sensor includes a first image sensor 1041 and a second image sensor 1042, which should not be construed as a specific limitation of the present embodiment. As shown in fig. 2, a first focusing lens is installed behind the lens 101, and the object focal plane of the first focusing lens coincides with the image focal plane of the lens 101, so as to ensure that light emitted from the first focusing lens is parallel light; then, the light is converged on the image space focal plane of the second focusing lens again through the second focusing lens arranged behind the first focusing lens, so that the secondary imaging of the target object is realized, wherein the focal length of the second focusing lens is larger than that of the first focusing lens, so that the flange distance of the lens 101 is prolonged better, and the spectroscope 103 is added in the light path; after passing through the beam splitter 103, the light beam is split into two parts, and the two sub-light beams emitted from the beam splitter 103 correspond to the same optical phase in the transmission process; the first image sensor 1041 and the second image sensor 1042 may perform image acquisition at the same time.
Fig. 3 is a schematic diagram of a structure of the synchronous shooting device corresponding to fig. 2, and fig. 4 is a schematic diagram (specifically, a side view) of a physical structure of the synchronous shooting device corresponding to fig. 3. As shown in fig. 3 or 4, the synchronous photographing device includes a lens 101, a first focusing lens 1021, a second focusing lens 1022, a beam splitter 103, a first image sensor 1041 and a second image sensor 1042, and further includes a housing 105, a first connection unit 1061 and a second connection unit 1062. The housing 105 is used for packaging the first focusing lens 1021, the second focusing lens 1022 and the beam splitter 103, the first connecting unit 1061 is used for connecting the beam splitter 103 with the first image sensor 1041, and the second connecting unit 1062 is used for connecting the beam splitter 103 with the second image sensor 1042. Of course, the synchronous shooting device may also include other connection units and functional components not shown in the drawings.
According to the technical scheme, the secondary imaging unit is arranged behind the lens, the flange distance of the lens is effectively prolonged, practicable conditions are provided for mounting the light splitting unit, and then the light path splitting is realized by utilizing the light splitting unit, so that the effect that images of the same target object are synchronously acquired by utilizing at least two image sensors under the same external environment, sub-beams received by all the image sensors correspond to the same optical phase in the transmission process, and the position equivalence among all the image sensors is maintained. Compared with the mode of changing the positions of the image sensors or realizing synchronous image acquisition of a target object by using a fixed support capable of fixing a plurality of image sensors, the embodiment also does not need to change the positions of the image sensors in the shooting process, can reduce the optical phase difference (the phase difference causes the difference of image information contained in different images) caused by the position difference between different image sensors in the imaging process, and further can reduce synchronous shooting errors for the same object, and ensure the ideal effect of image synthesis by using synchronously shot images; in addition, the technical scheme of the embodiment does not need manual participation in the synchronous shooting process, and the operation process is convenient and efficient.
