Description

Technical Field

[0001] The utility model relates to the technical field of camera angle adjustment, and in particular to a device capable of quickly adjusting the camera angle. Background Art

[0002] The camera angle will be adjusted frequently during the camera calibration process of the unmanned mining car. Generally, a spirit level and an angle ruler will be used in the adjustment process. The specific operation includes placing a spirit level near the camera installation position first, adjusting the horizontal position of the camera until the bubble displayed on the spirit level is in the middle position, using an angle ruler to measure the angle of the camera, and adjusting the angle of the camera as needed to ensure that the required angle and viewing angle are captured. According to the instructions of the spirit level and angle ruler, the position of the camera is gradually fine-tuned until the ideal level and angle are reached, and then the camera is fixed.

[0003] Since the camera on the mine car is installed very high and is restricted by factors such as space, it is difficult to adjust it to the exact angle in reality. In addition, multiple adjustments are usually required during the calibration process, which is very cumbersome and wastes manpower and time.

[0004] It can be seen that it is crucial to study a device that can quickly adjust the camera angle. Utility Model Content

[0006] The outer frame has coaxial U-shaped holes and arc-shaped through holes on two opposite sides in the vertical direction;

[0007] A bracket assembly, the camera being fixed thereto and being installed inside the outer frame, a rotating shaft being fixed between two opposite sides of the bracket assembly, the rotating shaft being rotatable along the U-shaped hole; and a special-shaped hole and a round hole for the rotating shaft to pass through are respectively provided on two opposite sides of the bracket assembly; and

[0008] The mounting bolt has an axial groove at the end thereof adapted to the special-shaped hole; the mounting bolt passes through the arc-shaped through hole and the special-shaped hole to fix the bracket assembly, and the bracket assembly uses the rotating shaft as the rotating axis and is tightened after adjusting the position along the arc-shaped through hole.

[0009] Furthermore, the axial length of the groove accounts for 1 / 4 of the overall length of the mounting bolt.

[0010] Furthermore, the end face of the mounting bolt has a dot mark; the edge of the arc-shaped through hole is provided with a scale mark, and the "0" scale is located in the middle of the scale mark.

[0011] Furthermore, the U-shaped hole is arranged along the vertical direction of the outer frame; and the arc-shaped through hole is located below the U-shaped hole.

[0012] Furthermore, the horizontal cross-section of the bracket assembly is a "concave"-shaped structure.

[0013] Furthermore, the camera is fixed on a plane of the bracket assembly away from the rotating shaft.

[0014] Preferably, the outer frame is a box-shaped structure that partially wraps the bracket assembly, and a rain cap is obliquely extended from the top of the opening surface of the outer frame.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model adjusts the mounting bolts, takes the rotating shaft as the rotating axis and tightens it after positioning along the arc-shaped through hole, reads the dot marks and the corresponding scale line marks on the bolts, and can obtain the rotation angle, thereby realizing rapid adjustment of the camera angle and saving manpower and time costs.

[0022] In order to make the technical scheme and technical effect of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

[0023] Example

[0024] like Figure 1-2 As shown, the utility model provides a device for quickly adjusting the angle of a camera, comprising an outer frame 1, a bracket assembly 2, a mounting bolt 3 and a camera 4, specifically:

[0025] The outer frame 1 is a box-shaped structure that partially wraps the bracket assembly 2. A coaxial U-shaped hole 11 and an arc-shaped through hole 12 are respectively provided on opposite sides of the outer frame 1 in the vertical direction. The U-shaped hole 11 is provided in the vertical direction of the outer frame 1, and the arc-shaped through hole 12 is located below the U-shaped hole 11. A scale mark 13 is provided at the edge of the arc-shaped through hole 12, and the "0" scale is located in the middle of the scale mark 13. A rain cap 14 is provided at an angle extending from the top of the opening surface of the outer frame 1.

[0026] The camera 4 is fixed on the bracket assembly 2, and the bracket assembly 2 is installed inside the outer frame 1. The horizontal cross-section of the bracket assembly 2 is a "concave"-shaped structure, and the opposite sides of the bracket assembly 2 are respectively provided with a special-shaped hole 22 and a round hole for the rotation shaft 21 to pass through, and the rotation shaft 21 is fixed between the opposite sides of the bracket assembly 2, and the rotation shaft 21 can rotate along the U-shaped hole 11, that is, the bracket assembly 2 can rotate around the rotation shaft 21. The camera 4 is fixed on the plane of the bracket assembly 2 away from the rotation shaft 21.

[0027] The end of the mounting bolt 3 is axially provided with a groove 31 adapted to the special-shaped hole 22, and the axial length of the groove 31 accounts for 1 / 4 of the overall length of the mounting bolt 3. The function of the groove 31 is to limit the relative rotation of the mounting bolt 3 and the bracket assembly 2, ensuring that the dot mark 32 and the "0" scale of the scale mark 13 always correspond.

[0028] The end surface of the mounting bolt 3 has a dot mark 32, and the rotation angle can be obtained by matching the dot mark 32 on the mounting bolt 3 with the scale mark 13 of the outer frame 1. Each scale mark on the scale mark 13 represents a fixed angle, and the angle represented by each scale mark can be agreed upon.

[0029] The mounting bolt 3 passes through the arc-shaped through hole 12 and the special-shaped hole 22 to fix the bracket assembly 2. The bracket assembly 2 uses the rotating shaft 21 as the rotation axis and is adjusted and positioned along the arc-shaped through hole 12 and then tightened to quickly adjust the angle of the camera 4.

[0030] When in use, the position of the mounting bolt 3 in the arc-shaped through hole 12 is adjusted by rotation until the camera 4 is adjusted to an accurate angle. The operation is convenient and quick.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
