The present invention relates to the technical field of photography and videography, in particular to a gear fine-tuning pan-tilt. The gear fine-tuning pan-tilt includes a rotating base, a roll worm support seat, a roll adjusting assembly, a pitch adjusting assembly, and a bearing seat arranged in sequence from bottom to top; the pitch adjusting assembly of the complete gear structure is located on the above, providing large-angle pitch ability, and the roll adjusting assembly located below adopts an arc-shaped rack structure, which reduces the interference to the pitching movement of the upper assembly and makes the height of the pan-tilt smaller. The arc opening of the arc-shaped rack faces upwards, so that the rotation axis is closer to the center axis of the lens, the camera displacement is small during the leveling process, and the unintended picture movement is small. The upper and lower combination of the two structures strengthens the swing ability of the top of the pan-tilt in the limited size, and is therefore more convenient to use: firstly aiming at the subject through the rotating base, and then leveling the left and right, and then determining the pitch angle. The camera always maintains the left and right level during pitching process. There is no need to level the left and right again after the pitch angle is changed, and roll deviation will not occur when the camera pitches and the lens is moved.

A display device is provided. The display device includes a screen body, a first angle adjustment mechanism, a connecting arm, a second angle adjustment mechanism, and a pedestal. The screen body is provided with a first set of positioning holes and a second set of positioning holes. A first angle adjustment mechanism is selectively connected to the screen body through the first set of positioning holes or the second set of positioning holes, so that the screen body is disposed vertically or horizontally. The first angle adjustment mechanism is pivotally connected to the connecting arm, so that the screen body and the connecting arm are rotatable relative to each other. The second angle adjustment mechanism is pivotally connected to the connecting arm and the pedestal, so that the connecting arm and the pedestal are rotatable relative to each other.

A calibration support includes a support body (100) configured to mount a calibration element, the calibration element being configured to calibrate a driving assistance system of a vehicle (500); an image acquisition device (200) connected to the support body (100) and configured to acquire an image of the vehicle (500); a processing device (300) provided on the support body (100), electrically connected to the image acquisition device (200), and configured to calculate, according to the image acquired by the image acquisition device (200), the movement position of the support body (100) relative to the vehicle (500) and output a control signal comprising the movement position; and a control device (400) provided on the support body (100), electrically connected to the processing device (300), and configured to receive the control signal and control the support body (100) to move.
