A method includes providing a fixture including a target in a field of view of a sensor mounted to a vehicle. The target is detectable by the sensor. The fixture includes a first rangefinding device and a second rangefinding device spaced from the first rangefinding device. The method includes measuring a first angle and first distance from the first rangefinding device to a first known point on the vehicle; measuring a second angle and second distance from the second rangefinding device to a second known point on the vehicle; determining a position and orientation of the target in a coordinate system relative to the vehicle based on the first angle, the first distance, the second angle, and the second distance; and calibrating the sensor based on the position and orientation of the target.

Provided in the present disclosure are a camera apparatus and a mobile terminal. The camera apparatus of the present disclosure comprises: a camera assembly; a rotary shaft that is fixedly connected to the camera assembly, a first gear being fixed at an end of the rotary shaft that is away from the camera assembly; a transmission component that is fixed on the rotary shaft and that abuts against the camera assembly; a screw rod that is rotationally connected to the transmission component, a second gear being fixed on the screw rod, and the screw rod and the rotary shaft being arranged in parallel; and a control structure that is connected to the screw rod, the control structure driving the screw rod to rotate, and the screw rod rotatingly driving the transmission component to move along the central axis of the rotary shaft.

A support system for a display device includes a first arm configured to extend from a support surface. A second arm is rotatably connected to the first arm. The second arm has a range of movement relative to the first arm. A tilt head is rotatably connected to the second arm and configured to connect to a display. A first biasing member is positioned in the second arm and configured to provide a first counterbalancing force to the second arm to offset a load of the display. A second biasing member is positioned in the second arm and configured to provide a second counterbalancing force to the second arm to offset the load of the display. A lockout mechanism is configured to disengage the second biasing member and eliminate the second counterbalancing through at least a portion of the range of motion.

A wall mount type display device according to an embodiment of the present disclosure may include a main body on which a display is provided, a wire having opposite ends connected to the main body, and a wall mount assembly which is fixed to a wall and to which the wire is hung to support the main body. The wall mount assembly may include a pair of supporting bars which support the wire and extend in a direction closer to each other toward the upper side, a first link rotatably connecting upper end portions of the pair of supporting bars to each other, a long hole formed through the supporting bar and extending in a longitudinal direction of the supporting bar, a second link located at a height lower than the first link, a protrusion protruding from opposite ends of the second link and inserted into the long hole, and a fixing member fixed to the wall through the protrusion.

A gimbal photographing device includes a body including a supporting wall and a side wall adjacent to the supporting wall, a folding mechanism connected to the body and configured to rotate around a rotation axis, and a gimbal camera connected to the folding mechanism and having an expanded state and a folded state. In response to the folding mechanism driving the gimbal camera to rotate to the expanded state, at least a portion of the folding mechanism abuts against the supporting wall. In response to the folding mechanism driving the gimbal camera to rotate to the folded state, the gimbal camera fits to the side wall of the body.

A coupling system for peripheral devices may include a housing and a shaft assembly. An end of the shaft assembly is threaded and couples to and uncouples from a peripheral device by relative rotational movement between the peripheral device and the shaft assembly. An inner cavity of the housing and another end of the shaft assembly defines a limited range of rotational motion between first and second rotational positions. Rotating the shaft assembly to the first rotational position allows for the peripheral device to be rotated relative to both the shaft assembly and the housing to couple the peripheral device to the housing via the shaft assembly. With the peripheral device coupled to the shaft assembly, relative rotational motion between the peripheral device and the housing is allowed between the first rotational position and the second rotational position without rotating the peripheral device relative to the shaft assembly.

A photographing device support having an auxiliary handle includes: a telescopic support body, a connecting apparatus, and a clamping apparatus; and an auxiliary handle for an operator to grip, one end of the auxiliary handle is provided with a hinge joint, and the auxiliary handle is up-and-down rotatably connected to the connecting apparatus by the hinge joint, the hinge joint is provided with a first convex platform, and the connecting apparatus is provided with an elastic locking piece, the elastic locking piece cooperates with the first convex platform, so that when the auxiliary handle rotates downwards to fold relative to the telescopic support body, the elastic locking piece is elastically deformed at first to enable the first convex platform to rotate upwards and cross over the elastic locking piece, and then is reset to prevent the first convex platform from rotating back, so as to lock the auxiliary handle.
