Referring to fig. 1, the panoramic scanning carrier 40 according to the first embodiment of the present invention includes a base 11, a rotating platform 12, a light guiding mechanism 13, and an optical element carrier 1341. The optical element supporting platform 1341 is disposed on the base 11, the light guiding mechanism 13 is disposed on the rotating platform 12, the rotating platform 12 may rotate relative to the base 11, and the optical element supporting platform 1341 may rotate synchronously with the rotating platform 12.
The base 11 has a support shaft 126, and the rotating platform 12 rotates around the support shaft 126 relative to the base 11, so as to drive the light guiding mechanism 13 to rotate, that is, the rotating shaft of the rotating platform 12 is coaxial with the support shaft 126. The rotary table 12 has a rotation axis about which the rotary table 12 rotates. Specifically, the rotary platform 12 includes a rotary upper platform 121, a rotary lower platform 122, and a rotary shaft 123. The support shaft 126 may be disposed on the base 11 and penetrates the lower rotating platform 122. The rotating shaft 123 is sleeved on the supporting shaft 126, and the rotating shaft 123 penetrates through the lower platform 122. The rotating platform 12 may further be provided with a driving motor 124, and the rotating shaft 123 is driven by the driving motor 124 to rotate around the supporting shaft 126, so as to drive the rotating upper platform 121 and the rotating lower platform 122 to rotate around the supporting shaft 126, that is, the rotating shaft of the rotating platform 12 is coaxial with the supporting shaft 126 and the rotating shaft 123. The driving motor 124 may be disposed on the lower rotating platform 122, and the driving motor 124 drives the rotating shaft 123 to rotate through a transmission component (not shown) so as to drive the upper rotating platform 121 and the lower rotating platform 122 to rotate in the horizontal direction, and the light guide mechanism 13 disposed on the upper rotating platform 12 also rotates together.
The optical element carrying platform 1341 is used for carrying an optical element, where the optical element may be an imaging module or a light emitting module, and the imaging module may be an infrared imaging module, a visible light imaging module, a curtain, and the like, and may be selected as required. The light emitted by the light emitting module can exit from the panorama scanning carrying device 40 after being reflected by the light guiding mechanism 13, and the light entering and exiting the optical element is parallel to the rotation axis.
The optical element support platform 1341 may be driven by the rotation shaft 123 to rotate synchronously with the rotation platform 12, i.e., the rotation angular velocity of the optical element support platform 1341 may be the same as the rotation angular velocity of the rotation platform 12, and the rotation axis of the optical element support platform 1341 is coaxial with the rotation axis of the rotation platform 12. The optical element carrier 1341 is rotatable synchronously with the rotary stage 12 via a locking assembly 125. Specifically, the optical element supporting platform 1341 may be disposed on the rotating platform 12, and may rotate relative to the base 11 under the driving of the driving motor 124. Specifically, the optical element supporting platform 1341 may be disposed on the rotating shaft 123 and supported on the base 11 through the supporting shaft 126. One end of the support shaft 126 may be supported on the base 11, and the optical element supporting platform 1341 is disposed at an end of the support shaft 126 away from the base 11. The rotating shaft 123 may be driven by a driving motor 124 to rotate the optical element supporting platform 1341 and the rotating platform 12 synchronously. Specifically, the upper rotating stage 121 has an opening 1211, and the optical element supporting stage 1341 is disposed in the opening 1211 and is exposed from the opening 1211, so that light can enter and exit the optical element disposed on the optical element supporting stage 1341. The optical element support platform 1341 may be disposed coaxially with the support shaft 126, i.e., the axis of rotation of the optical element support platform 1341 is coaxial with the support shaft 126.
The light guide mechanism 13 includes a galvanometer unit 135 disposed in a housing 132, and the housing 132 has a window 1326 to allow light to enter the housing 132. The galvanometer unit 135 is suspended with respect to the optical element support platform 1341, and the galvanometer unit 135 integrally rotates around the optical element support platform 1341. Specifically, the galvanometer unit 135 includes a support beam 1351, a cantilever beam 1352, a galvanometer lens 1353, and a galvanometer motor 1354. The suspension beam 1352 is suspended on the optical element carrying platform 1341 under the support of the support beam 1351. the vibrating mirror 1353 is suspended on the suspension beam 1352, so that the vibrating mirror 1353 is suspended relative to the optical element supporting platform 1341, and the vibrating mirror 1353 is spaced from the optical element supporting platform 1341. The positional relationship between the vibrating mirror 1353 and the optical element supporting platform 1341 is satisfied, the vibrating mirror 1353 is disposed on the light beam of the optical element, and reflects the light beam entering and exiting the optical element, and the light beam incident on the vibrating mirror 1353 is reflected and then incident on the optical element supporting platform 1341. Further, the light incident from the window 1326 is incident on the optical element support platform 1341 in a direction parallel to the rotation axis of the rotation platform 12. further, the positional relationship among the galvanometer lens 1353, the window 1326 and the optical element support platform 1341 is satisfied, and the light incident from the window 1326 is reflected by the galvanometer lens 1353 and then directly enters the optical element support platform 1341; in response, light emitted from the optical element support platform 1341 is reflected by the galvanometer mirror 1353 and exits the window 1326. In this embodiment, when the rotating platform 12 rotates by 360 degrees, the angle formed by the reflecting surface of the galvanometer lens 1353 and the imaging surface of the optical element supporting platform 1341 remains unchanged. Further, the window 1326 may be a 360 degree panoramic window, disposed around the housing 132. In this embodiment, the angle formed between the vibrating mirror 1353 and the surface of the optical element support platform 1341 is 45 degrees, so that the incident light entering the vibrating mirror 1353 from the window 1326 is perpendicular to the reflected light entering the optical element support platform 1341 after being reflected by the Jing Zhenjing mirror 1353. Further, the rotation axis of the vibrating mirror 1353 may be parallel to the rotation axis 123 and the support axis 126; specifically, the cantilever 1352, the rotation axis of the vibrating mirror 1353, the rotation axis of the optical element support platform 1341, and the support axis 126 may all be coaxially disposed, that is, the rotation axis of the vibrating mirror 1353 during rotation, the rotation axis of the optical element support platform 1341, and the support axis 126 may all be coaxially disposed. preferably, the rotation axis of the galvanometer lens 1353, the rotation axis of the optical element support platform 1341 and the support shaft 126 are coaxially disposed, that is, the galvanometer lens 1353 may be suspended directly above the optical element support platform 1341, so that incident light can enter the optical element support platform 1341 more precisely, and the compensation effect of the galvanometer lens 1353 can be improved, thereby obtaining a clearer image.
The galvanometer motor 1354 is configured to drive the galvanometer lens 1353 to rotate reversely with respect to the rotation direction of the rotating platform 12. The vibrating mirror 1353 is at the initial position when it is not compensated for rotation. The vibrating mirror 1353 is driven by the vibrating mirror motor 1354 to rotate and swing within a range of plus or minus 10 degrees at a preset frequency relative to the initial position and reset. Further, the mirror 1353 is driven by the driving motor 124 to rotate in synchronization with the rotation of the rotation platform 12, and simultaneously, when the mirror 1354 is driven, it is capable of rotating in the reverse and forward directions relative to the rotation direction of the rotation platform 12. Specifically, the vibrating mirror 1353 may be driven by the vibrating mirror motor 1354 to switch the rotation direction in the horizontal direction with the cantilever 1353 as the rotation axis at a preset frequency, that is, rotate 10 degrees counter clockwise or clockwise relative to the initial position, and then return to the initial position quickly for resetting. The "preset frequency" may be selected according to the imaging frequency of the imaging module carried by the optical element carrying platform 1341, so as to match the preset frequency with the imaging frequency. When the imaging module images, a synchronization signal may be sent to the galvanometer motor 1354 to drive the galvanometer lens 1353 to rotate in a reverse direction relative to the direction of rotation of the optical element support platform 12 in response to the synchronization signal to compensate for the image formed in the imaging module. When the imaging module is not imaging, the galvanometer lens 1353 then rotates in synchronization with the rotation stage 12. Since the cantilever 1352 is disposed coaxially with the optical element support platform 1341, the vibrating mirror 1353 is suspended above the optical element support platform 1341, and rotates about the symmetry axis of the optical element support platform 1341. In addition, during panoramic scanning, the rotation direction of the vibrating mirror 1353 is opposite to the rotation direction of the rotating platform 12, so as to compensate the movement of the incident light beam relative to the optical element supporting platform 1341 during scanning. Further, it is preferable that the angular velocity of the inverse rotation of the vibrating mirror 1353 is substantially the same as the rotational angular velocity of the rotating platform 12, so that the imaging module in the optical element carrying platform 1341 achieves the best compensation effect during imaging, and the imaging is clearer. When the optical element supporting platform 1341 is provided with an imaging module, the inverse vibration of the vibrating mirror 1353 can be used to compensate the motion of the image of the object in the imaging module during the imaging process, so that the image of the object in the imaging module is stationary, that is, the motion of the image of the object on the imaging module is compensated by the inverse rotation motion of the vibrating mirror 1353, so that the image of the object on the area array image sensor is stationary, thereby improving the recognition accuracy of the obtained panoramic image.
Further, the panoramic scan carriage 40 may further include a rotary motor (not shown) for controlling the tilting motion of the galvanometer mirror 1353 and the optical element carriage 1341 to control the pitch angle, thereby controlling the viewing range.
Referring to fig. 2 and fig. 3 together, a panoramic scanning carrier 50 according to a second embodiment of the present invention includes a base 11, a rotating platform 14, and a light guiding mechanism 13. The rotating platform 14 is disposed on the base 11, the light guiding mechanism 13 is disposed on the rotating platform 14, and the rotating platform 14 is rotatable relative to the base 11.
The panoramic scan carriage 50 according to the second embodiment of the present invention is substantially the same as the first embodiment, and is different in that the rotating platform 14 includes a rotating disc 141 and a rotating motor 142, and the optical element carriage 1341 and the galvanometer unit 135 are disposed on the rotating disc 141 and are driven by the rotating motor 142 disposed on the base 11 to rotate synchronously.
Specifically, the support beam 1351 and the optical element supporting platform 1341 are disposed on the rotating disc 141, and are driven by the driving motor 14 to rotate synchronously with the rotating disc 141, and the optical element supporting platform 1341 may be disposed at a position of the rotating shaft of the rotating disc 141. Further, since the vibrating mirror 1353 is connected to the support beam 1351 through the cantilever 1352, the vibrating mirror 1353 can rotate 360 degrees with respect to the optical element support platform 1341. During rotation, the window 1326 rotates synchronously with the rotating disk 141, so that the light incident from the window 1326 is reflected by the galvanometer lens 1353 and then enters the optical element support platform 1341. In this embodiment, the rotating disk 141 may be a rotating gear for driving the support beam 1351 and the optical element supporting platform 1341 to rotate synchronously. The vibrating mirror 1353 and the viewing window 1326 can be located at the same horizontal plane.
In addition, during photographing, the vibrating mirror 1353 is driven by the vibrating mirror motor 1354 to reversely rotate within a range of plus or minus 10 degrees at a predetermined frequency and then return to its original position.
It will be appreciated that the optical element support platform 1341 may be a region of the base 11, and may be selected as desired.
Referring to fig. 4, a panoramic scanning carrier 60 according to a third embodiment of the present invention includes a base 11, a rotating platform 14, and a light guiding mechanism 13. The rotating platform 14 is disposed on the base 11, the light guiding mechanism 13 is disposed on the rotating platform 14, and the rotating platform 14 is rotatable relative to the base 11.
The panoramic scanning load device 60 according to the third embodiment of the present invention has substantially the same structure as the panoramic scanning load device 50 according to the second embodiment, and is different in that the rotating platform 14 is integrally disposed in the housing 132, and the window 1326 may be a 360-degree panoramic window, and is disposed around the housing 132. During rotation of the galvanometer unit 135, light incident from the window 1326 is reflected by the galvanometer lens 1353 and enters the optical element support platform 1341. Further, since the window 1326 is a panoramic window and is located at the same horizontal plane as the vibrating mirror 1353, a larger angle of view can be obtained during rotation, and shielding of the housing 132 is avoided.
Referring to fig. 5, fig. 5 is a schematic structural diagram of the panoramic scanning carrier 40 in the present embodiment, the imaging module 134 is disposed on the optical element carrier 1341, and an optical axis of the imaging module 134 may be coaxially disposed with a rotation axis of the vibrating mirror 1353. The incident light is reflected by the mirror 1353 and enters the imaging module 134. By rotation of the galvanometer lens 1353, a panoramic image in an angle range of 360 degrees can be acquired. Meanwhile, the imaging module 134 has a predetermined imaging frequency, during the rotation and image capturing process of the galvanometer lens 1353, the galvanometer lens 1353 rotates reversely and positively around the cantilever 1352 under the driving of the galvanometer motor 1354 at a predetermined frequency matched with the imaging frequency, so that the imaging module 134 compensates the imaging acquired by the imaging module 134 during imaging, the image acquired by the imaging module 134 is static, thereby ensuring enough static exposure time, obtaining a clear image, and having high resolution precision.
It can be understood that the panoramic scanning module can be other panoramic scanning bearing devices, and can be selected and combined differently according to actual needs so as to achieve different monitoring effects.
In addition, other variations within the spirit of the invention will occur to those skilled in the art, and such variations as may be included within the scope of the invention as claimed.
