Technical Field

[0001] The utility model relates to the technical field of light field imaging, in particular to a light field imaging device with adjustable viewing angle. Background Art

[0002] There are generally two ways to collect light fields in light field imaging technology: multiplexing and multi-sensor capture. The mainstream multiplexing method uses microlens array imaging, and multi-sensor capture usually uses multiple cameras to form a camera array. The light recorded by each microlens unit in the microlens array corresponds to the scene image at the same position but different viewing angles, obtaining four-dimensional light field data.

[0003] According to a disclosed light field imaging device (publication number: CN219145502U), the above application uses a group of cameras to rotate and capture images, which greatly reduces the number of cameras in the camera array, streamlines the size of the array, and reduces the cost of the device.

[0004] When the device is put into actual use, the viewing angle of the camera cannot be adjusted and can only be fixed in the same direction, resulting in a limited shooting range of the camera and an inability to capture more images. The device is not very convenient to use and has low practicality. Utility Model Content

[0024] The above-mentioned rotating mechanism 6 includes a sliding rod 61, a threaded rod 62, a cross bar 63, a turntable 64, a knob 65, and a rubber pad 66; the sliding rod 61 is slidably connected to the inner wall of the bracket 1, and the bottom of the sliding rod 61 is rotatably connected to the turntable 64. The turntable 64 cooperates with the sliding rod 61, the threaded rod 62, and the cross bar 63 to support the bracket 1 so that the bracket 1 remains in a suspended state. At this time, the bracket 1 can be rotated. When the bracket 1 rotates, the sliding rod 61 will be driven to rotate on the top of the turntable 64. At the same time, the bracket 1 will also drive the camera 5 to rotate horizontally, so that the viewing angle of the camera 5 can be adjusted. The bottom of the turntable 64 is fixedly installed with a rubber pad 66, and the rubber pad 66 can be used to improve the distance between the turntable 64 and the ground or the workbench. The friction force between them enables the turntable 64 to stably support the bracket 1. One end of the threaded rod 62 is rotatably connected to the inner wall of the sliding rod 61, and the other end of the threaded rod 62 passes through the sliding rod 61 and is fixedly installed with a knob 65. The threaded rod 62 is rotatably connected to the penetration point of the sliding rod 61, and the cross bar 63 is fixedly installed on the inner wall of the bracket 1. The cross bar 63 can slide upward on the inner wall of the sliding rod 61 to drive the bracket 1 to move upward synchronously, so that the bottom of the bracket 1 can be suspended, and the outer wall of the cross bar 63 fits the inner wall of the sliding rod 61. The inner wall of the cross bar 63 is threadedly connected to the outer wall of the threaded rod 62. The threaded rod 62 is rotated by the knob 65 to drive the cross bar 63 threadedly connected thereto to slide up and down on the inner wall of the sliding rod 61.

[0025] The supporting mechanism 7 comprises a screw rod 71, a handle 72, a slider 73, a slide plate 74, a push rod 75 and a connecting rod 76; one end of the screw rod 71 is rotatably connected to the inner wall of the cross bar 63, the other end of the screw rod 71 passes through the cross bar 63 and is fixedly installed with a handle 72, and the screw rod 71 is rotatably connected to the cross bar 63 and the bracket 1 at the penetration point, the inner wall of the cross bar 63 is slidably connected with the slider 73, the inner wall of the slider 73 is threadedly connected with the outer wall of the screw rod 71, the screw rod 71 is rotated by the handle 72, and the slider 73 threadedly connected with it is driven to slide on the inner wall of the cross bar 63, the side wall of the bracket 1 is slidably connected with the slide plate 74, the bottom of the slide plate 74 is fixedly installed with a push rod 75, and the push rod 75 is provided There are two groups, and the two groups of top rods 75 are mirror-set at the two ends of the slide plate 74 with the cross bar 63 as the central axis. The slide plate 74 slides downward and cooperates with the top rod 75 to lift the bracket 1, so that one side of the bracket 1 is tilted upward. At this time, the inclination angle of the camera 5 will also change accordingly, so that the pitch angle of the camera 5 can be adjusted, which is convenient for the camera 5 to capture a wider picture. The side wall of the slide plate 74 is hinged with a connecting rod 76, and the end of the connecting rod 76 away from the slide plate 74 is hinged to the bottom of the slider 73. When the slider 73 slides on the inner wall of the cross bar 63 toward the side close to the handle 72, it will squeeze the connecting rod 76, so that the connecting rod 76 squeezes the slide plate 74 downward, causing the slide plate 74 to slide downward on the side wall of the bracket 1.

[0026] Working principle: when the viewing angle of the camera 5 needs to be adjusted, the threaded rod 62 is rotated by the knob 65 to drive the cross bar 63 threadably connected thereto to slide upward on the inner wall of the slide bar 61. At the same time, the cross bar 63 will drive the bracket 1 to move upward synchronously until the bottom of the bracket 1 is in a suspended state. At this time, the turntable 64, the slide bar 61, the threaded rod 62, and the cross bar 63 can be used to support the bracket 1 so that the bracket 1 remains in a suspended state. At this time, the bracket 1 can be rotated. When the bracket 1 rotates, it will drive the slide bar 61 to rotate on the top of the turntable 64. At the same time, the bracket 1 will also drive the camera 5 to rotate horizontally, so that the viewing angle of the camera 5 can be adjusted, which is convenient for shooting different places and more convenient to use.

[0027] By rotating the screw rod 71 through the handle 72, the slider 73 threadably connected to it is driven to slide on the inner wall of the cross bar 63 toward the side close to the handle 72. At the same time, the slider 73 will squeeze the connecting rod 76, so that the connecting rod 76 will squeeze the slide plate 74 downward, so that the slide plate 74 slides downward on the side wall of the bracket 1 and drives the top rod 75 at the bottom to fit the ground and continue to slide downward. At this time, the top rod 75 can be used to lift one side of the bracket 1 to tilt the bracket 1 upward, so that the pitch angle of the camera 5 can be adjusted, which is convenient for the camera 5 to capture a wider picture.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
