[0016] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0017] Example 1 like Figure 1 , Figure 4 and Figure 6 As shown, this utility model embodiment provides an optical simulation remote sensing satellite, including a simulation remote sensing satellite 1. The bottom of the simulation remote sensing satellite 1 is provided with an adjustment mechanism 2 for adjusting the side tilt angle, pitch angle and orbital altitude of the simulation remote sensing satellite 1. The bottom of the adjustment mechanism 2 is provided with a support mechanism 3 for supporting the simulation remote sensing satellite 1 and the adjustment mechanism 2.
[0018] The simulated remote sensing satellite 1 includes a telephoto imaging unit 4, a visible short-focus imaging unit 5, an infrared short-focus imaging unit 6, a satellite cabin 7, two solar panels 8, and two data transmission antennas 9. The telephoto imaging unit 4, visible short-focus imaging unit 5, and infrared short-focus imaging unit 6 are respectively located inside the satellite cabin 7. In this embodiment, the telephoto imaging unit 4, visible short-focus imaging unit 5, and infrared short-focus imaging unit 6 are specifically fixedly installed on the bottom inner wall of the satellite cabin 7, and the rear side of the satellite cabin 7 can be opened. The two solar panels 8 are symmetrically installed on the left and right sides of the satellite cabin 7, and the two data transmission antennas 9 are symmetrically installed on the rear side of the satellite cabin 7. In this embodiment, the solar panels 8 and data transmission antennas 9 are simulated components, only demonstrating the shape of the satellite and having no actual function. To reduce the weight of the simulated satellite, both the solar panels 8 and data transmission antennas 9 are made of plastic.
[0019] In this embodiment, the telephoto imaging unit 4 is used for outdoor imaging, specifically using two imaging channels to achieve visible light and infrared imaging; while the visible short-focus imaging unit 5 and the infrared short-focus imaging unit 6 are used for indoor target imaging, specifically, the visible short-focus imaging unit 5 is used for visible light imaging of indoor targets, and the infrared short-focus imaging unit 6 is used for infrared imaging of indoor targets. When the optical simulation remote sensing satellite of this embodiment transfers from indoor imaging to outdoor imaging, the focal plane circuits on the visible short-focus imaging unit 5 and the infrared short-focus imaging unit 6 need to be removed from the short-focus lenses and replaced on the telephoto lens of the telephoto imaging unit 4. The specific operation process is as follows: open the rear side of the satellite compartment 7, then remove the focal plane circuits on the short-focus imaging unit 5 and the infrared short-focus imaging unit 6 from the short-focus lenses and install them on the telephoto lens of the telephoto imaging unit 4. The wires of the telephoto imaging unit 4, the visible short-focus imaging unit 5, and the infrared short-focus imaging unit 6 are pulled out through the rear side of the satellite compartment 7 to the outside of the satellite compartment 7.
[0020] like Figure 7 and Figure 8As shown, in this embodiment, the telephoto imaging unit 4 includes a mounting cylinder 31, a light shield 32, a support plate 33, a visible channel 34, an infrared channel 35, an infrared focal plane circuit 36, a visible focal plane circuit 37, and two focusing mechanisms 38. The support plate 33 is vertically fixedly installed on the bottom inner wall of the satellite compartment 7. The mounting cylinder 31 is fixedly connected to the support plate 33 and penetrates through the support plate 33. The light shield 32 is fixedly sleeved on the front end face of the mounting cylinder 31. The infrared channel 35 is fixedly connected and installed on the rear side of the mounting cylinder 31. The visible channel 34 is vertically connected to the infrared channel 35. The two focusing mechanisms 38... Mechanism 38 is connected to the rear end of visible channel 34 and infrared channel 35 respectively. Infrared focal plane circuit 36 and visible focal plane circuit 37 are detachably connected to focusing mechanism 38 on infrared channel 35 and visible channel 34 respectively through flanges. In this embodiment, focusing mechanism 38 adopts 7STM02125 micro displacement platform developed by Saifan Optoelectronics. Visible focal plane circuit 37 adopts imported large pixel size focal plane circuit to ensure image quality. The sensor type of visible focal plane circuit 37 is sCMOS. The sensor type of infrared focal plane circuit 36 is imported vanadium oxide uncooled infrared focal plane detector, resulting in clear images.
[0021] The mounting cylinder 31 contains a primary reflector 39 and a secondary reflector 40 that are parallel to each other. An inclined plate 41 is located at the connection between the visible channel 34 and the infrared channel 35. The inclined plate 41 has an inclination angle of 45°. The infrared channel 35 contains three infrared lenses 42, and the visible channel 34 contains three visible lenses 43. In this embodiment, both the primary reflector 39 and the secondary reflector 40 are made of 6061 rapid-cooling aluminum. The primary reflector 39 has a diameter of φ186mm and an effective light-transmitting diameter of φ180mm. The secondary reflector 40 has a diameter of φ67mm and a light-transmitting diameter of φ65.4mm.
[0022] When the teaching device of this embodiment is located outdoors, the reflected light from the object being photographed is reflected sequentially by the primary reflector 39 and the secondary reflector 40, and then split into visible light and long-wave infrared light by the tilting plate 41. The visible light and infrared light then enter the interior of the visible channel 34 and the infrared channel 35, respectively, and are corrected for off-axis aberrations by three visible lenses 43 and three infrared lenses 42, respectively. The light is then transmitted to the interior of the visible focal plane circuit 37 and the infrared focal plane circuit 36, respectively, and focused onto the focal plane of the CMOS image sensor. The CMOS image sensor converts the received light signal into an electrical signal through photoelectric conversion and performs data processing and control (gain, analog-to-digital conversion, parallel-to-serial conversion, etc.), converting it into a standard LVDS signal and outputting it to the control chip FPGA. The FPGA processes and controls the received image data (serial-to-parallel conversion, decoding, processing, rearrangement, etc.), converting it into an LVTTL signal and outputting it to the GE interface unit. The GE interface unit converts the data into a standard GE protocol network signal and transmits it to the computer with the network card via a network cable.
[0023] like Figure 9 and Figure 10 As shown, in this embodiment, the visible short-focus imaging unit 5 includes a first camera mounting cylinder 44, a visible short-focus lens 45, and a visible focal plane circuit 37. The first camera mounting cylinder 44 is fixedly installed on the bottom inner wall of the satellite compartment 7. The visible short-focus lens 45 is disposed inside the first camera mounting cylinder 44. The visible focal plane circuit 37 is connected to the rear side of the first camera mounting cylinder 44 via a flange. The infrared short-focus imaging unit 6 includes a second camera mounting cylinder 46, an infrared short-focus lens 47, and an infrared focal plane circuit 36. The second camera mounting cylinder 46 is fixedly installed on the bottom inner wall of the satellite compartment 7. The infrared short-focus lens 47 is disposed inside the second camera mounting cylinder 46. The infrared focal plane circuit 36 is detachably connected to the rear side of the second camera mounting cylinder 46 via a flange. Specifically, in this embodiment, the visible short-focus lens 45 adopts an existing visible C-mount adjustable focus lens, covering... The focal length is 25~75mm (image plane not less than 1"), while the infrared short focal length lens 47 in this embodiment adopts an existing long-wave infrared adjustable focusing lens, covering a focal length of 35~150mm (image plane not less than 2 / 3"). In specific implementation, since the visible short focal length imaging unit 5 and the infrared short focal length imaging unit 6 do not work simultaneously with the long focal length imaging unit 4, only the visible short focal length imaging unit 5 and the infrared short focal length imaging unit 6 are used when imaging indoors, while only the long focal length imaging unit 4 is used when imaging outdoors. Therefore, in this embodiment, the visible short focal length imaging unit 5 and the infrared short focal length imaging unit 6 share the visible focal plane circuit 37 and the infrared focal plane circuit 36 with the long focal length imaging unit 4, respectively. In specific applications, the focal plane circuits on the visible short focal length imaging unit 5 and the infrared short focal length imaging unit 6 can be removed from the short focal length lens and replaced on the long focal length lens of the long focal length imaging unit 4.
[0024] Table 1 shows the parameters of short focal length lenses.
[0025] The front side of the satellite compartment 7 is provided with light inlets 10 for providing light to the telephoto imaging unit 4, the visible short-focus imaging unit 5, and the infrared short-focus imaging unit 6. This embodiment, through the design of three light inlets 10, allows external light to enter the interior of the satellite compartment 7 through the three light inlets 10, providing illumination to the lenses of the telephoto imaging unit 4, the visible short-focus imaging unit 5, and the infrared short-focus imaging unit 6.
[0026] like Figure 4 As shown, in this embodiment, the adjustment mechanism 2 includes a first adjustment unit 11 for adjusting the focal length of the simulated remote sensing satellite 1, a second adjustment unit 12 for adjusting the side tilt angle of the simulated remote sensing satellite 1, and a third adjustment unit 13 for adjusting the pitch angle of the simulated remote sensing satellite 1. The bottom of the first adjustment unit 11 is connected to the support mechanism 3, the second adjustment unit 12 is disposed on the top of the first adjustment unit 11, and the third adjustment unit 13 is disposed on the top of the second adjustment unit 12.
[0027] Example 2 like Figure 2 , Figure 3 and Figure 5 As shown, the optical simulation remote sensing satellite provided in this embodiment has the same structure as that in Embodiment 1, except that the first adjustment unit 11 specifically includes a sliding guide rail 14, a screw 15, a sliding block 16, and a first motor 17. The sliding guide rail 14 and the first motor 17 are located on the top of the support mechanism 3. The two ends of the screw 15 are rotatably connected to the sliding guide rail 14 through bearings. The bottom of the sliding block 16 is slidably connected to the sliding guide rail 14, and the top is connected to the second adjustment unit 12. Due to the limiting effect of the sliding guide rail 14 on the sliding block 16, when the screw 15 rotates, the sliding block 16 cannot rotate with the screw 15, but can only slide along the screw 15 and the sliding guide rail 14. The sliding block 16 is threadedly connected to the screw 15, and the output shaft of the first motor 17 is fixedly connected to one end of the screw 15.
[0028] When it is necessary to adjust the focal length of the simulated remote sensing satellite 1, the first motor 17 can be started to drive the screw 15 to rotate synchronously, so that the sliding block 16 moves back and forth along the screw 15 and the sliding guide rail 14, thereby realizing the adjustment of the focal length of the simulated remote sensing satellite 1; furthermore, the sliding guide rail in this embodiment is provided with a scale for marking the movement distance of the sliding block 16, and the setting of the scale makes it easy to know whether the focal length has been adjusted properly.
[0029] Example 3 like Figure 2 and Figure 3As shown, the optical simulation remote sensing satellite provided in this embodiment has the same structure as that in Embodiment 1, except that the second adjustment unit 12 specifically includes a mounting base 18, a second motor 19, a rotating cylinder 20, and a rotating plate 21. The mounting base 18 is connected to the top of the first adjustment unit 11, specifically, the mounting base 18 is connected to the top of the sliding block 16. The second motor 19 is located on the top of the mounting base 18. The rotating cylinder 20 is sleeved above the second motor 19. The bottom of the rotating plate 21 is connected to the second motor 19. Specifically, in this embodiment, the output shaft of the second motor 19 is fixedly connected to the bottom of the rotating plate 21. The rotating plate 21 is a circular plate, and the outer diameter of the rotating plate 21 matches the inner diameter of the rotating cylinder 20. The rotating plate 21 is fixedly connected to the inner wall of the rotating cylinder 20. The top of the rotating cylinder 20 is connected to the third adjustment unit 13.
[0030] When it is necessary to adjust the side tilt angle of the simulated remote sensing satellite 1, the second motor 19 is started to drive the rotating plate 21 to rotate, which in turn drives the rotating cylinder 20 to rotate synchronously, thereby adjusting the side tilt angle of the remote sensing satellite 1.
[0031] Example 4 like Figure 2 and Figure 3 As shown, the optical simulation remote sensing satellite provided in this embodiment has the same structure as that in Embodiment 1. The only difference is that the third adjustment unit 13 specifically includes a first U-shaped connecting plate 22, a second U-shaped connecting plate 23, a third motor 24, and a rotating shaft 25. The first U-shaped connecting plate 22 is disposed on the top of the second adjustment unit 12, specifically, the first U-shaped connecting plate 22 is disposed on the top of the rotating cylinder 20, and the second U-shaped connecting plate 23 is inserted and disposed above the first U-shaped connecting plate 22. The third motor 24 and the rotating shaft 25 are both disposed inside the first U-shaped connecting plate 22. The third motor 24 is connected to one end of the rotating shaft 25, and the other end of the rotating shaft 25 rotates through the first U-shaped connecting plate 22 and is fixedly connected to the second U-shaped connecting plate 23. In this embodiment, the third motor 24 is disposed on one side of the vertical plate of the first U-shaped connecting plate 22. The output shaft of the third motor 24 is fixedly connected to one end of the rotating shaft 25. The other end of the rotating shaft 25 is rotatably connected to the other side of the vertical plate of the first U-shaped connecting plate 22 through a bearing. The other end of the rotating shaft 25 passes through the other side of the vertical plate of the first U-shaped connecting plate 22 and is fixedly connected to the vertical plate of the adjacent second U-shaped connecting plate 23. The vertical plate of the first U-shaped connecting plate 22 on which the third motor 24 is disposed is rotatably connected to the vertical plate of the adjacent second U-shaped connecting plate 23.
[0032] When it is necessary to adjust the pitch angle of the simulated remote sensing satellite 1, the third motor 24 is started, which drives the rotating shaft 25 to rotate, thereby driving the second U-shaped connecting plate 23 to rotate back and forth synchronously, thus realizing the adjustment of the pitch angle of the remote sensing satellite 1.
[0033] Example 5 The optical simulation remote sensing satellite provided in this embodiment has the same structure as that in Embodiment 1, except that the support mechanism 3 specifically includes a support frame 26, four support units, and four casters 27. The top of the support frame 26 is connected to the bottom of the adjustment mechanism 2, and specifically, the top of the support frame 26 is connected to the bottom of the sliding guide rail 14. The four support units are symmetrically arranged on the support frame 26, and the four casters 27 are respectively arranged at the four bottom corners of the support frame 26. In this embodiment, the support frame 26 is composed of 90mm*90mm profiles.
[0034] In this embodiment, each support unit includes a fixed support leg 28, a connecting block 29, and a support screw 30. The connecting block 29 is connected to the support frame 26, and the support screw 30 is threadedly connected to the connecting block 29. The fixed support leg 28 is disposed at the bottom of the support screw 30.
[0035] When the optical simulation remote sensing satellite of this embodiment needs to be moved, the support frame 26 is pushed, and the entire device is moved by the rolling action of the casters 27. When the device needs to be fixed in a suitable position, the support screw 30 is rotated, so that the support screw 30 moves downward along the connecting block 29. When the fixed support leg 28 contacts the ground, the entire device is supported and fixed by the fixed support leg 28.
[0036] When using the optical simulation remote sensing satellite provided in this embodiment, if indoor imaging is required, the entire device is moved to a suitable position, and then the first motor 17 is started, driving the screw 15 to rotate synchronously, so that the sliding block 16 moves back and forth along the screw 15 and the sliding guide rail 14, thereby adjusting the focal length of the simulation remote sensing satellite 1. Then, the second motor 19 is started, driving the rotating plate 21 to rotate, driving the rotating cylinder 20 to rotate synchronously, adjusting the side tilt angle of the remote sensing satellite 1. Then, the third motor 24 is started, driving the rotating shaft 25 to rotate, thereby driving the second U-shaped connecting plate 23 to rotate back and forth synchronously, adjusting the pitch angle of the remote sensing satellite 1. After adjustment, the long focal length imaging unit 4, the visible short focal length imaging unit 5, and the infrared short focal length imaging unit 6 are used to perform indoor imaging or outdoor imaging, respectively.
