Pan-tilt and fuselage synchronous locking photography mode of triaxial photography unmanned aerial vehicle in non-flight state

Abstract

At present, when a three-axis photography unmanned aerial vehicle is in a non-flight state, the unmanned aerial vehicle cannot perform unlimited purposeful free shooting if the inclination of a fuselage exceeds a design range. Therefore, the value of the unmanned aerial vehicle is limited, and the creativity of a purchaser is also limited. According to the practical function of the three-axis photography unmanned aerial vehicle, a non-flight photography mode is added into a flight control program of the unmanned aerial vehicle, so that the photography function is expanded after the cradle head and the fuselage are synchronously locked in a non-flight state of the three-axis photography unmanned aerial vehicle, and the use opportunity of the three-axis photography unmanned aerial vehicle in environments such as a no-fly zone and an indoor environment is improved. And the expanded photographing function certainly enhances the experience feeling and the gaining feeling of the user. Therefore, the three-axis photography unmanned aerial vehicle has a new value which is inevitably embodied in the competitiveness of the whole photography equipment industry. And the system can be expanded to sales of peripheral products of the unmanned aerial vehicle, for example, the system is not a stabilizer, a foot stool and the like of an unmanned aerial vehicle assembly before and also becomes a part of common accessories of the unmanned aerial vehicle.

Description

Technical Field

[0001] The three-axis photography drone has expanded photography functions when not in flight. Background Art

[0002] 1. Limitations of the shooting function of the three-axis photography drone when it is not in flight

[0003] Currently, when powered on and not in flight, the gimbal and lens of various brands of three-axis camera drones, whether stationary or handheld, can only effectively shoot in a horizontal position within their designed range. If the tilt angle of the drone exceeds the designed range, the gimbal and lens will not be able to capture the intended image.

[0004] 2. The shooting angles are limited by the hardware design.

[0005] For example, the pitch angles of the DJI Mavic 3 series drones are limited by a protruding design on the front of the drone, covering the lens. This limits the maximum upward lens angle to 35 degrees, and the downward lens angle to 90 degrees. Shooting angles can only be adjusted between 35 degrees and -90 degrees; shooting beyond this angle is impossible.

[0006] 3. Policy and regulatory restrictions

[0007] Based on safety and confidentiality, there are no-fly restrictions in places like airports, military bases, prisons, high-speed rail stations, government offices, and indoor areas. However, photography is permitted in safe, non-confidential areas within these no-fly zones. Therefore, a no-fly restriction does not mean a ban, but it does reduce the likelihood of drone use.

[0008] 4. For some pilots, drones are their only photography tool besides their phones.

[0009] In many environments where flying is inconvenient or unnecessary, relying on drones for non-flying photography has become a necessity for some people. However, due to limitations in gimbal (lens) leveling, appearance, and other conditions, many shooting opportunities and fun are lost. Some people even sell their drones at a low price due to low utilization.

[0010] 5. The need for competition

[0011] The emergence of drones has lowered the barrier to entry for aerial photography and increased competition in the photography equipment industry. However, due to insufficient exploration of non-flying photography skills, many photography enthusiasts still need other photographic equipment to achieve the same photography goals.

[0012] This will inevitably lead to higher costs, greater storage burdens, and more operational coordination issues. Expanding the shooting limits of three-axis photography drones when not in flight naturally increases the competitiveness of photography drones. Summary of the Invention

[0013] The invention proposed in this patent adds a "non-flight mode" to the three-axis camera drone, enabling the gimbal and the drone to be locked synchronously in this mode. This allows the three-axis camera drone to be unrestricted in its non-flight state: free pitch, tilt, rotation, and even flip, allowing for purposeful shooting, offering users new creative options.

[0014] In addition to expanding the drone's shooting capabilities, this mode also ensures that the propellers will not be accidentally activated when they are turned on, avoiding injuries to children, novices or curious onlookers. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In the drone control program, drones launched after the "non-flight mode" function is added can add a "stationary (non-flight mode) gear" on the remote controller (attached) Figure 1 : Remote control gear diagram), when the camera drone is in non-flying state, by sliding the slider to the "Standstill (non-flying mode)" gear, you can directly start the "non-flying mode" shooting function.

[0016] In addition to the mode selection function, this gear can also ensure that the propeller will not be activated when it is open, avoiding injuries to children, novices and curious onlookers. DETAILED DESCRIPTION

[0017] 1. Add a "non-flight mode" option to the flight control program. Through programming instructions, the gimbal and the fuselage of the three-axis camera drone can be synchronized and locked in this mode.

[0018] 2. Program Design Limitation: This function can only be activated when the propeller motor is not in takeoff or stopped. In flight mode, this gear is invalid or has the same function as the low speed gear.

[0019] 3. By editing program instructions, you can adapt the pan / tilt rotation, left / right shaking and other functions to the remote control joystick, dial or button to realize the remote control of various functions.

[0020] Note: Each brand of drone has its own technical architecture, and each brand has its own habits in editing the command to switch to "non-flight mode". You only need to edit it according to their own characteristics, but the ultimate goal is to realize the "non-flight mode" function.

[0021] 4. A new "Station (Non-Flight Mode)" position has been added to the remote control. When the camera drone is not in flight, you can directly activate the "Non-Flight Mode" shooting function by sliding the slider to the "Station (Non-Flight Mode)" position.

[0022] 5. The drone software has been upgraded to be compatible with various photography drones that were released before this feature was implemented. Experienced pilots can upgrade the software and select "Non-Flight Mode" or replace the remote control with a "Station (Non-Flight Mode)" position to use this feature, allowing older drones that were released before this feature was implemented to maintain or increase their value.

Claims

1. The rights protected by this patent application are to add a "non-flight photography mode" to the three-axis photography drone program. This mode allows the gimbal, lens, and body to synchronize and lock, allowing the lens to move in sync with the body, enabling targeted photography in any posture. The content of these applications for protection reflects the specific functional expansion of the "photographic techniques and visual language" related to three-axis photography drones:

1. The photography function of the photography drone is expanded by placing the lens vertically upward (currently, three-axis photography drones of various brands cannot be placed vertically to perform purposeful photography). 1-1. Stand still or follow the plane flying upwards through the gap between dense buildings (or other narrow spaces). 1-2. Shoot a time-lapse of the sky vertically upwards and still. 1-3. Through program settings, you can achieve time-lapse photography of wide-range, multi-angle spatial changes. For example, you can start from the upper rear of the fuselage (35 degrees) and end at the distant view in front of the fuselage (belly -90 degrees, or even lower angles). 1-4. Use the remote control to adjust the pitch and tilt to shoot long-range shots from the upper rear of the fuselage (35 degrees) to the front of the fuselage (belly -90, or even lower angles). 1-5. The camera follows the car horizontally from far to near, and then passes by "overhead".

2. Expanded photography capabilities for drones with their belly facing upwards (currently, three-axis drones cannot perform unlimited, purposeful photography when their belly faces upwards). 2-1. Place the camera on the ground and shoot from a low angle to capture the scene of tourists walking past. 2-2. Place the camera on the conveyor belt of the production line and shoot pictures introducing the production process as the production line moves.

3. Expanded photography capabilities for drones mounted on stabilizers (currently, three-axis drones cannot shoot effectively if their pitch and tilt angles exceed the set range when attached to a stabilizer). 3-1. The drone is fixed on a handheld stabilizer, which can realize the shooting techniques of all the functions of the stabilizer + traditional camera. 3-2. The drone is fixed on a handheld stabilizer, and the stabilizer operator cooperates with the drone operator to achieve more special communication effects.

4. The drone lens rotates or shakes left and right to shoot (currently, three-axis photography drones cannot perform purposeful rotation or shaking of the head when not in flight). 4-1. Walking in a narrow corridor filled with flowers, the camera rotates to create a rotating effect. 4-2. The drone is stationary, and the camera moves from the flowers in the front left to the people in the middle and long shot on the right.

5. The photography function of the photography drone is expanded by installing it on an extension pole (or rocker arm). 5-1. The camera moves vertically upward through the branches and leaves of the dense tree canopy, from capturing the image of a tree laden with fruits, to extending through the tree canopy to capture the sky, and finally panning the camera to capture the entire valley. 5-2. Shoot the pontoons (or Aragon) coming and going from low under the bridge, then pan up to shoot the village (or the entire city). 5-3. Use hanging to shoot underground rescue or interior scenes of narrow spaces such as chimneys. The above-mentioned functions that drones can achieve but do not yet have limit the appreciation potential of drones and also restrict the creativity of users.
