Description

Technical Field

[0001] This utility model belongs to the field of photogrammetry simulation technology, and in particular relates to a multi-degree-of-freedom aerial photogrammetry simulation device. Background Technology

[0002] Chinese patent CN205333065U discloses a five-degree-of-freedom aerial photogrammetry simulation system, including a guide rail system, a gimbal mechanism, an imaging device, and a control device. The guide rail system includes three linear tracks and a motion platform. By fixing the imaging device to the bottom of the gimbal mechanism, the control device can operablely control the movement of the motion platform on the track system and the movement of the imaging device on the gimbal mechanism, realizing the translation of the aircraft in three-dimensional space and the pitch and roll movements of the imaging device relative to the aircraft. The shortcomings of this technical solution are: the method of driving the gimbal mechanism and the imaging device to move is through individual motors. This driving method makes the movement of the gimbal mechanism and the imaging device smooth, but it cannot reproduce the body sway that occurs during the take-off, landing, and turning of the aircraft in actual operation. Therefore, it cannot fully practice and improve the aircraft control skills of the simulated operator.

[0003] To address these issues, we provide a multi-degree-of-freedom aerial photogrammetry simulation device. Utility Model Content

A gyroscope ring assembly is mounted on the upper end of the UAV and connected to a connecting rod at the lower end of the horizontal sliding sleeve. During simulated flight photogrammetry, the UAV is operated to push the horizontal sliding sleeve laterally on the horizontal sliding rod. The UAV then pushes the horizontal sliding rod, causing the vertical frame components on both sides to slide longitudinally. The UAV also pushes the horizontal sliding rod to slide vertically within the vertical frame components on both sides. During turning and ascent / descend, the UAV will sway due to its own inertia and that of the horizontal sliding sleeve, achieving realistic flight simulation and improving operational skills.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see Figures 1 to 4 This invention relates to a multi-degree-of-freedom aerial photogrammetry simulation device, comprising a three-dimensional frame component 1 and a drone 2. The three-dimensional frame component 1 includes two sets of vertical frame assemblies 101, two sets of vertical frame assemblies 102, and a horizontal slide bar 103. By sliding one set of vertical frame assemblies 102 longitudinally within each of the two sets of vertical frame assemblies 101, and by sliding the horizontal slide bar 103 vertically within each of the two sets of vertical frame assemblies 102, the three-dimensional frame component 1 is formed by the two sets of vertical frame assemblies 101, the two sets of vertical frame assemblies 102, and the horizontal slide bar 103, and is used to simulate the three-dimensional motion path of an aircraft. The drone 2 is connected to the horizontal slide bar 103 by sliding it laterally onto the horizontal slide sleeve 103a. A gyroscope ring assembly 201 is installed at the upper end, and the gyroscope ring assembly 201 is connected to the connecting rod 103b at the lower end of the horizontal sliding sleeve 103a. When performing simulated flight photogrammetry, the UAV 2 is operated to fly, so that the UAV 2 pushes the horizontal sliding sleeve 103a to slide laterally on the horizontal sliding rod 103. The UAV 2 pushes the horizontal sliding rod 103 to drive the vertical frame assemblies 102 on both sides to slide longitudinally. The UAV 2 pushes the horizontal sliding rod 103 to slide vertically in the vertical frame assemblies 102 on both sides. When turning and ascending, the UAV 2 will sway under the inertia of itself and the horizontal sliding sleeve 103a, realizing realistic flight simulation and improving the level of operation skills.

[0026] Specifically, two sets of vertical frame components 102 are horizontally slidably arranged in two sets of vertical frame components 101, and the two ends of the horizontal slide rod 103 are vertically slidably sleeved on the two sets of vertical frame components 102. A gyroscope ring component 201 is provided at the upper end of the UAV 2, and a horizontal slide sleeve 103a is slidably sleeved on the outside of the horizontal slide rod 103. A connecting rod 103b is fixed at the lower end of the horizontal slide sleeve 103a, and the connecting rod 103b is connected to the gyroscope ring component 201 in a transmission connection.

[0027] Furthermore, the vertical frame assembly 101 includes two vertical support rods 101a and a vertical slide rail 101b, and the vertical frame assembly 102 includes a vertical slide rod 102a and a sliding roller 102b. The upper ends of the two vertical support rods 101a are fixedly connected to the two ends of the vertical slide rail 101b, and the sliding roller 102b is slidably sleeved on the vertical slide rail 101b. The vertical slide rod 102a is fixedly installed on one side of the sliding roller 102b, and the two ends of the horizontal slide rod 103 are vertically slidably sleeved on the outside of the vertical slide rod 102a in the two vertical frame assemblies 102.

[0028] Furthermore, the sliding roller component 102b includes a roller seat sleeve 102b-1, three roller seats 102b-2, and three sets of sliding rollers 102b-3. The roller seat sleeve 102b-1 is a U-shaped plate structure with the opening facing downwards. The three roller seats 102b-2 are respectively fixedly installed on the inner side wall of the roller seat sleeve 102b-1. The three sliding rollers 102b-3 are respectively rotatably installed in the three roller seats 102b-2. The two sides and the upper end face of the longitudinal slide rail 101b are respectively provided with sliding roller grooves 101b-1 along the length direction of the longitudinal slide rail 101b. The three sets of sliding rollers 102b-3 are respectively slidably sleeved in the three sliding roller grooves 101b-1. The vertical sliding rod 102a is fixedly installed on one side of the roller seat sleeve 102b-1. Through the rolling friction between the sliding rollers 102b-3 and the roller grooves 101b-1, the friction force during the movement of the vertical frame assembly 102 is reduced.

[0029] Furthermore, a bottom slide rail 101c is fixedly sleeved at the lower end of the two vertical support rods 101a, and a wheel seat 102c is fixedly sleeved at the lower end of the vertical slide rod 102a. A roller 102c-1 is rotatably installed inside the wheel seat 102c. A wheel groove 101c-1 is opened on the upper surface of the bottom slide rail 101c along the length direction of the bottom slide rail 101c. The lower wheel surface of the roller 102c-1 is fitted and rolls in the wheel groove 101c-1. The roller 102c-1 bears part of the weight of the vertical slide rod 102a and reduces the friction at the bottom of the vertical slide rod 102a during movement.

[0030] Furthermore, bottom trays 101c-2 are fixedly installed on the lower sides of both ends of the bottom slide rail 101c to stably install the entire three-dimensional frame component 1.

[0031] Furthermore, a set of tie rods 101a-1 are vertically arrayed and fixedly connected between the two vertical support rods 101a in the longitudinal frame assembly 101, so that the two vertical support rods 101a in the longitudinal frame assembly 101 are firmly connected.

[0032] The operation process in this embodiment is as follows:

[0033] During simulated flight, the drone 2 is operated to move and slide. The drone 2 pushes the horizontal slide sleeve 103a to slide laterally on the horizontal slide bar 103. The drone 2 pushes the horizontal slide bar 103 to slide vertically on the two vertical slide bars 102a. The drone 2 pushes the horizontal slide bar 103 to drive the two vertical slide bars 102a to slide horizontally longitudinally in the two vertical frame components 101. When the drone 2 performs acceleration actions such as turning, sudden stop, or ascent and descent, the drone 2 and the horizontal slide sleeve 103a will shake due to acceleration, thus reproducing the actions in the real flight process. Example 2

[0034] Please see Figures 1 to 5 Based on Embodiment 1, the gyro ring assembly 201 includes a horizontal rotating ring 201a and a vertical rotating ring 201b. By horizontally rotating the outer ends of the horizontal rotating ring 201a into the adapter cylinder 202 at the upper end of the UAV 2, and horizontally rotating the outer ends of the vertical rotating ring 201b into the horizontal rotating ring 201a, the connecting rod 103b is rotatably installed in the ring of the vertical rotating ring 201b. When the UAV 2 moves to one side, the body of the UAV 2 tilts, and the vertical rotating ring 201b and the horizontal rotating ring 201a rotate relative to the adapter cylinder 202, so that the connecting rod 103b at the lower end of the horizontal sliding sleeve 103a remains vertical.

[0035] Specifically, the upper end of the UAV 2 is fixedly provided with an adapter tube 202 extending upwards. The outer ends of the horizontal rotating ring 201a rotate horizontally within the adapter tube 202, and the outer ends of the vertical rotating ring 201b rotate vertically within the horizontal rotating ring 201a. The connecting rod 103b is rotatably installed within the ring of the vertical rotating ring 201b.

[0036] The operation process in this embodiment is as follows:

[0037] As the UAV 2 moves to one side, its body tilts, and the longitudinal rotation ring 201b and the transverse rotation ring 201a rotate relative to the adapter cylinder 202, keeping the connecting rod 103b at the lower end of the transverse sliding sleeve 103a vertical, thereby preventing the propeller of the UAV 2 from colliding with the transverse sliding rod 103.
