DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The singular forms "a", "said" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two.

[0033] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0034] It should be understood that although the terms first, second, third, etc. may be used to describe structures in the disclosed embodiments, these structures should not be limited to these terms. These terms are only used to distinguish different structures. For example, without departing from the scope of the disclosed embodiments, a first component may also be referred to as a second component, and similarly, a second component may also be referred to as a first component.

[0035] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0036] It should also be noted that the term "includes", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprising a ..." do not exclude the existence of other identical elements in the commodity or device including the elements.

[0037] In the relevant technology, the observation of the target is the ultimate goal in the field of photoelectric detection. How to achieve 360° full-field observation and rapid imaging in a limited space is a difficult problem in the field of detection. First of all, a single lens cannot achieve observation of a large field of view. It is necessary to provide a single lens with multiple degrees of freedom of motion such as pitch, azimuth and roll to achieve this. This requires a turntable and a large swing angle for the lens, which will greatly increase the volume of the detection equipment. The introduction of the turntable also brings in a lot of mechanical and electrical control costs, while increasing the failure rate of the entire system and reducing the reliability of the entire system; Another problem is that the response speed required to achieve full-field detection of a single lens through the pitch, azimuth and roll of the turntable is very low, because it is necessary to wait for the pitch, azimuth and roll speed of the turntable, which greatly reduces the observation efficiency. The current mainstream detection equipment, such as theodolite, uses a single lens equipped with a multi-dimensional turntable to achieve full-field detection. Although it can achieve full-field detection scanning in terms of function, the cost is very high and the response is very low. Especially for large targets moving rapidly, it is almost difficult to achieve detection and tracking. At the same time, since it is equipped with a single lens, a larger lens aperture and complex optical design are often required, which brings difficulties and costs to the entire system and also puts greater pressure on the assembly and adjustment equipment.

[0038] In order to solve at least one of the above-mentioned technical problems, the present disclosure provides a 360° full-field-of-view rapid imaging system, which includes: a lens housing 100, which is a spherical surface, and a plurality of light-transmitting windows 110 are provided on the spherical surface, wherein the plurality of light-transmitting windows 110 are arranged in an array, and the normals passing through the plane where the light-transmitting windows 110 are located all converge at the center of the spherical surface; an image acquisition device, wherein the image acquisition device is configured to acquire a 360° full-field-of-view image; wherein the image acquisition device includes a plurality of image acquisition units 200, and the image acquisition units 200 are arranged in a one-to-one correspondence with the light-transmitting windows 110, so that the image acquisition units 200 acquire images through the light-transmitting windows 110; each of the image acquisition units 200 has an image acquisition field of view with a preset angle; wherein two adjacent image acquisition fields of view at least partially overlap at a preset distance, and the at least partially overlapping image acquisition fields of view account for 0.01-20% of the image acquisition fields of view at the preset distance. The 360° full-field-of-view rapid imaging system disclosed in the present invention can achieve full-field-of-view observation through the array of light-transmitting windows 110 of the lens housing 100 and the array of image acquisition units 200. There is no need to design a complex, large-aperture, and difficult optical system and a large-sized detector, and there is no need to design a complex, multi-degree-of-freedom, large-angle turntable. This greatly improves the reliability of the system, reduces the difficulty of the system, and reduces the cost of the system. Since there is no need to rotate the turntable, the target can be observed quickly in real time without time delay.

[0039] The optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0040] Figure 1 A schematic structural diagram of a lens housing 100 according to an embodiment of the present disclosure is shown. Figure 2 A schematic structural diagram of an image acquisition unit 200 according to an embodiment of the present disclosure is shown. Figure 3 FIG. 2 shows a schematic diagram of the field of view of a 360° full-field-of-view rapid imaging system according to an embodiment of the present disclosure. Figure 1 , Figure 2 and Figure 3As shown, according to a specific embodiment of the present disclosure, on the one hand, a 360° full-field-of-view rapid imaging system is provided, and the 360° full-field-of-view rapid imaging system comprises: a lens housing 100, the lens housing 100 is a spherical surface, and a plurality of light-transmitting windows 110 are opened on the spherical surface, and the plurality of light-transmitting windows 110 are arranged in an array, and the normals passing through the plane where the light-transmitting windows 110 are located all converge at the center of the spherical surface; an image acquisition device, the image acquisition device is configured to acquire a 360° full-field-of-view image; wherein the image acquisition device comprises a plurality of image acquisition units 200, and the image acquisition units 200 are arranged in a one-to-one correspondence with the light-transmitting windows 110, so that the image acquisition units 200 acquire images through the light-transmitting windows 110; each of the image acquisition units 200 has an image acquisition field of view of a preset angle; wherein two adjacent image acquisition fields of view at least partially overlap at a preset distance, and the at least partially overlapping image acquisition fields of view account for 0.01-20% of the image acquisition fields of view at the preset distance. It should be noted that the preset acquisition range in the present disclosure is the range covered by the field of view of the 360° full-field-of-view rapid imaging system. Figure 3 As shown, points A, B, C and D form a surface S1 of the image acquisition field of view of an image acquisition unit at a preset distance, and the surface S2 of the image acquisition field of view of the adjacent image acquisition unit at a preset distance is composed of points E, F, G and H. It can be seen that S1 and S2 have a common surface, that is, surface S3 composed of points C, D, E and F, and S3 is the overlapping part of the two adjacent image acquisition fields at the preset distance. In this way, the image acquisition units 200 around each image acquisition unit 200 will have a large acquisition surface with it, thereby completing the full coverage of the acquisition surface at the boundary of the preset acquisition range. Because the image acquisition unit 200 and the lens shell 100 are arranged correspondingly, and the lens shell 100 is a concentric curved surface, when the lens shell 100 is a sphere, the 360° full-field-of-view rapid imaging system disclosed in the present invention can complete 360° full-market image acquisition, and the shape and size of the acquisition can also be designed according to needs. The 360° full-field-of-view rapid imaging system disclosed in the present invention has a hole opened at a calculated position to form the lens housing 100, and the light-transmitting window 110 for protection is embedded in the opened circular hole, and an image acquisition unit 200 is installed inside each of the light-transmitting windows 110 of the lens housing 100 to form a 360° full-field-of-view rapid imaging system.

[0041] The 360° full-field-of-view rapid imaging system provided by the present invention can design an ordinary camera into a wide-angle or full-field-of-view rapid imaging camera according to needs, arrange smaller simple lenses and lens shells 100 in an array according to the field of view boundary of a preset acquisition range, and achieve coverage of a larger field of view or a full field of view in the lens shell 100 array according to the field of view angle of the lens, so that the entire field of view can be observed and scanned in real time.

[0042] In some embodiments, the at least partially overlapping image acquisition field of view accounts for 0.8-10% of the image acquisition field of view at the preset distance. In an optional embodiment, the at least partially overlapping image acquisition field of view accounts for 1-8% of the image acquisition field of view at the preset distance. In an optional embodiment, the at least partially overlapping image acquisition field of view accounts for 2-6% of the image acquisition field of view at the preset distance. In an optional embodiment, the at least partially overlapping image acquisition field of view accounts for 3-5% of the image acquisition field of view at the preset distance. At the preset distance, the smaller the percentage of the overlapping image acquisition field of view to the image acquisition field of view, the less calculation is required for synthesizing the image later; in theory, the optimal implementation method is for two adjacent image acquisition fields of view to overlap only one row or one column of pixels.

[0043] In some embodiments, the preset distance is 0.06-8000km. In an optional embodiment, the preset angle is 30-60°. In an optional embodiment, the preset distance is 60-7000km. In an optional embodiment, the preset distance is 100-6500km. In an optional embodiment, the preset distance is 200-6000km. In an optional embodiment, the preset distance is 500-5000km. In an optional embodiment, the preset distance is 800-3000km. In an optional embodiment, the preset distance is 1000-2000km. The preset distance can be understood as the farthest distance that the 360° full field of view rapid imaging system of the present disclosure needs to image. The present disclosure is mainly used for ground-to-air observation and collection, and is usually used to collect images of flying objects above 200km.

[0044] Figure 4 FIG. 1 is a schematic structural diagram of a lens housing 100 according to another embodiment of the present disclosure. Figure 5 FIG. 1 is a schematic diagram showing the structure of a lens housing 100 according to another embodiment of the present disclosure. Figure 4 and Figure 5 As shown, in some embodiments, the lens housing 100 is a quarter sphere, and multiple lens housings 100 are spliced ​​into a preset shape. In an optional embodiment, one side of the lens housing 100 is provided with a tenon, and one side of the lens housing 100 is provided with a tenon groove; multiple lens housings 100 are spliced ​​into a preset shape through the tenon and the tenon groove. Figure 4In the embodiment, the lens housing 100 is a quarter sphere, and under the array arrangement in the 360° full-field-of-view rapid imaging system, the angle of the field of view is far greater than 90°; when two lens housings 100 are combined, under the array arrangement in the 360° full-field-of-view rapid imaging system, the angle of the field of view is far greater than 180°; when four lens housings 100 are combined, under the array arrangement in the 360° full-field-of-view rapid imaging system, 360° full-field-of-view acquisition without blind spots can be completed instantly.

[0045] Figure 6 FIG. 2 shows a schematic diagram of the structure of an image acquisition system according to an embodiment of the present disclosure. Figure 6 As shown, in some embodiments, the image acquisition system further includes: side panels 300, the number of which is the same as the number of sides of the lens housing 100, one side of the side panels 300 is connected to one side of the lens housing 100; and a bottom panel 400, the bottom panel 400 is connected to the other side of the side panel 300. The system installs the image acquisition device inside the lens housing 100, and the lens housing 100 cooperates with the side panels 300 and the bottom panel 400 to form a housing. The system can be understood as a four-way for theodolite, or as a camera fixing platform for an observation platform. The system is a hemisphere, but the frame is formed by cutting off the edge, and the plane formed by cutting off the edge of the hemisphere can be mounted with the theodolite.

[0046] Figure 7 FIG. 2 shows a schematic diagram of the structure of an image acquisition system according to another embodiment of the present disclosure. Figure 7As shown, in some embodiments, the image acquisition system further includes: a rotating platform 500, wherein the rotating platform 500 is configured to assemble a 360° full-field-of-view rapid imaging system and to allow one side of the lens housing 100 to rotate. In an optional embodiment, the rotating platform 500 includes: a base 510; a rotating portion 520, the rotating portion 520 is disposed on the base 510, and the rotating portion 520 is configured to rotate the 360° full-field-of-view rapid imaging system in a horizontal direction; a supporting portion 530, the supporting portion 530 is disposed at one end of the rotating portion 520 away from the base 510, and the supporting portion 530 is a U-shaped structure; the supporting portion 530 includes: a first wing plate 531, a web plate 532, and a second wing plate 533 connected in sequence, the web plate 532 is fixed to the supporting portion 530, and a connecting shaft is provided at one end of the first wing plate 531 and the second wing plate 533 away from the web plate 532, one end of the connecting shaft is connected to the first wing plate 531, and the other end of the connecting shaft is connected to the second wing plate 533, and the 360° full-field-of-view rapid imaging system is assembled on the connecting shaft, and the connecting shaft is configured to rotate the 360° full-field-of-view rapid imaging system in a vertical direction. The rotating platform 500 that can make the 360° full-field-of-view rapid imaging system rotate horizontally and the support part 530 that can make the 360° full-field-of-view rapid imaging system rotate vertically can realize the azimuth and pitch of longitude and latitude to achieve 360° full-field-of-view observation. Figure 3 , without the azimuth and pitch degrees of freedom, the system already has a field of view coverage of more than 180°, so only a very small azimuth and pitch angle are required to achieve full coverage of the field of view of 360°. Since the image acquisition unit 200 and the lens housing 100 of the array can already cover most of the field of view area, there is no need for the rotating table 500 to have multi-dimensional degrees of freedom and a wide range of swing angles, and the requirements for the degrees of freedom and angles of the rotating table 500 will be greatly reduced, and the rotating table 500 without a wide range of angles and multiple degrees of freedom can achieve full field of view scanning. In this way, the response speed of the rotating table 500 will also be greatly improved, and the complexity of the rotating table 500 will also be greatly reduced, which will greatly improve reliability, reduce difficulty, response speed and reduce costs.

In an optional embodiment, the concave surface of the lens housing 100 is provided with multiple mounting holes, and the mounting holes are located around the light-transmitting window 110; when the lens housing 100 covers the image acquisition unit 200, the protrusion 2321 is inserted into the mounting holes. The first fixing plate 231, the plurality of connecting posts 232 and the second fixing plate 233 form a whole, and at the same time form a cage frame, which is also a carrier for connecting the image acquisition unit 200 and the lens housing 100. In order to make the structure more compact and stable, the fixing frame 230 is formed by splicing multiple copper posts and fixing plates (i.e., the first fixing plate 231 and the second fixing plate 233), and forms a cage structure under the premise of ensuring the cavity space for fixing the image acquisition unit 200, thereby reducing the overall weight while ensuring stability and structural reliability.

[0050] The present disclosure aims to protect a 360° full-field-of-view rapid imaging system, which includes: a lens housing 100, which is a spherical surface, and a plurality of light-transmitting windows 110 are provided on the spherical surface, wherein the plurality of light-transmitting windows 110 are arranged in an array, and the normals passing through the plane where the light-transmitting windows 110 are located all converge at the center of the spherical surface; an image acquisition device, which is configured to acquire a 360° full-field-of-view image; wherein the image acquisition device includes a plurality of image acquisition units 200, and the image acquisition units 200 are arranged in a one-to-one correspondence with the light-transmitting windows 110, so that the image acquisition units 200 acquire images through the light-transmitting windows 110; each of the image acquisition units 200 has an image acquisition field of view of a preset angle; wherein two adjacent image acquisition fields of view at least partially overlap at a preset distance, and the at least partially overlapping image acquisition fields of view account for 0.01-20% of the image acquisition fields of view at the preset distance.
