Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a calibration and testing device for a drone camera ranging telescope. Background Technology

[0002] Rangefinders are common accessories for drone cameras. They help drone cameras determine the actual distance to targets, providing accurate information for subsequent surveying, marking, and strike operations.

[0003] As a unit module of the lens, the rangefinding telescope needs to be calibrated and tested during the production process to ensure the accuracy of its rangefinding function. Currently, the calibration method mostly adopts the fixed-point rangefinding method, which measures multiple targets at different distances at a fixed position and judges the accuracy by the readings. In actual use, there are some functional shortcomings and room for improvement. For example, multiple targets are needed in the measurement process, and the positions of the targets are relatively fixed. Switching targets requires adjusting the position of the equipment, which is quite troublesome and does not have a function to easily adjust the position of the targets.

[0004] Now, a novel calibration and testing device for drone camera ranging telescopes is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a calibration and testing device for a drone camera ranging telescope, in order to solve the problem mentioned in the background art of not having the function of easily adjusting the target position.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a calibration and testing device for a drone camera ranging telescope, comprising a first support frame, a second support frame welded to the left side of the first support frame, a supporting housing fixedly connected to the top of the first support frame, a positioning plate fixedly connected to the left side of the top of the supporting housing, a telescope port slot opened inside the positioning plate, a controller host fixedly connected to the right side of the top of the supporting housing, a ranging telescope wiring connected movably to the left side of the controller host, and an adjustment component for adjusting the target position inside the second support frame.

[0007] The adjustment assembly includes a threaded drive shaft, which is laterally movably connected between the two sides inside the second support frame. A servo motor is installed on the right side of the second support frame. Side fixing plates are fixedly connected to the two sides of the top of the second support frame. Two sets of transverse slide rods are laterally fixedly connected between the two sets of side fixing plates. A pre-opened slide groove is opened at the middle position of the top of the second support frame. A transverse slider is sleeved on the outside of the two sets of transverse slide rods. Two sets of slide rod holes are opened inside the transverse slider. An internally threaded slider is fixedly connected to the bottom end of the transverse slider. An internally threaded hole is opened inside the internally threaded slider. A target plate is fixedly connected to the top end of the transverse slider.

[0008] As a further technical solution of this utility model, the output end of the servo motor is connected to the right side of the threaded drive shaft, and the servo motor and the controller host are electrically connected.

[0009] As a further technical solution of this utility model, the transverse slide rod passes through the interior of the slide rod hole, the outer diameter of the transverse slide rod is adapted to the inner diameter of the slide rod hole, and the transverse slider can slide left and right along the outside of the transverse slide rod.

[0010] As a further technical solution of this utility model, the external shape and size of the internal thread slider are adapted to the internal shape and size of the pre-opened groove. The internal thread slider can slide left and right along the inside of the pre-opened groove. The thread drive shaft passes through the inside of the internal thread hole. The thread inside the internal thread hole and the thread outside the thread drive shaft match. The thread is a standard trapezoidal thread, and its thread helix angle is less than the equivalent friction angle.

[0011] As a further technical solution of this utility model, a sensor host is fixedly connected to the top of the positioning plate, a laser rangefinder is installed on the left side of the sensor host, the top of the target plate is higher than the top of the laser rangefinder, and the laser rangefinder and the sensor host are electrically connected.

[0012] As a further technical solution of this utility model, two sets of movable grooves are respectively opened at the front and rear ends of the top of the support housing, and electric cylinders are respectively installed at the front and rear ends inside the support housing. The output end of the electric cylinder is fixedly connected to a clamping plate. The shape and size of the clamping plate outside is adapted to the shape and size of the movable groove inside. The clamping plate can slide back and forth along the inside of the movable groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the UAV camera ranging telescope calibration and testing device not only realizes the function of facilitating target position adjustment, but also realizes the function of facilitating reference and comparison, and also realizes the function of facilitating telescope module fixation.

[0014] The system is equipped with a second support frame, a servo motor, a threaded drive shaft, a side fixing plate, a transverse slide bar, a pre-opened slide groove, a transverse slider, a slide bar hole, an internal threaded slider, an internal threaded hole, and a target plate. During use, the ranging telescope module to be calibrated is placed on the right side of the positioning plate, with its head end inserted into the telescope port slot. The tail end of the module is connected to the ranging telescope wiring. The ranging telescope module measures the actual distance to the target plate and feeds the result back to the controller host for easy reading. The position of the target plate can be adjusted as needed. The servo motor drives the threaded drive shaft to rotate continuously. The external thread of the threaded drive shaft and the internal threaded hole in the internal threaded slider engage, causing the transverse slider to slide left and right along the transverse slide bar. The position of the target plate changes synchronously, making the detection process more flexible and enabling easy adjustment of the target position.

[0015] With a positioning plate, telescope port slot, laser rangefinder sensor, and sensor host, the rangefinder telescope module measures the actual distance to the target plate during use. At the same time, the laser rangefinder sensor also measures simultaneously and feeds the results back to the LCD screen of the sensor host, which is convenient for users to refer to and compare, and judge the accuracy of the module, thus realizing the function of easy reference and comparison.

[0016] With a movable slot, an electric cylinder, and clamping plates, the rangefinder telescope module head is inserted into the telescope port slot during use. The electric cylinder is then activated, pushing the clamping plates to move along the movable slot. The four sets of clamping plates can hold and fix the rangefinder telescope module in place without the need for manual operation, thus achieving the function of easily fixing the telescope module.

[0025] Please see Figure 1-5 A UAV camera ranging telescope calibration and testing device also includes an adjustment component, which includes a threaded drive shaft 4. The threaded drive shaft 4 is laterally movably connected between the two sides inside the second support frame 2. A servo motor 3 is installed on the right side of the second support frame 2. Side fixing plates 5 are fixedly connected to the two sides of the top of the second support frame 2 respectively.

An internal threaded hole 11 is opened inside the internal threaded slider 10. A target plate 12 is fixedly connected to the top of the transverse slider 8.

[0026] The output end of the servo motor 3 is connected to the right side of the threaded drive shaft 4. The servo motor 3 and the controller host 21 are electrically connected. The transverse slide rod 6 passes through the interior of the slide rod hole 9. The outer diameter of the transverse slide rod 6 is matched with the inner diameter of the slide rod hole 9. The transverse slider 8 can slide left and right along the outside of the transverse slide rod 6. The shape and size of the external part of the internal thread slider 10 are matched with the shape and size of the inside of the pre-opened slide groove 7. The internal thread slider 10 can slide left and right along the inside of the pre-opened slide groove 7. The threaded drive shaft 4 passes through the interior of the internal thread hole 11. The thread inside the internal thread hole 11 matches the thread outside the threaded drive shaft 4. The thread is a standard trapezoidal thread with a thread helix angle smaller than the equivalent friction angle, which facilitates the adjustment of the target position.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the servo motor 3 drives the threaded drive shaft 4 to rotate continuously. The thread on the outside of the threaded drive shaft 4 and the internal thread hole 11 in the internal threaded slider 10 cooperate to drive the horizontal slider 8 to slide left and right along the horizontal slide bar 6. The position of the target plate 12 changes synchronously, which is more flexible in detection. The servo motor 3 and the controller host 21 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0028] The top of the positioning plate 14 is fixedly connected to the sensor host 17. The laser range sensor 16 is installed on the left side of the sensor host 17. The top of the target plate 12 is higher than the top of the laser range sensor 16. The laser range sensor 16 and the sensor host 17 are electrically connected for easy reference.

[0029] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the ranging telescope module measures the actual distance to the target plate 12. At the same time, the laser ranging sensor 16 also measures simultaneously and feeds the results back to the LCD screen of the sensor host 17, so that users can refer to it and judge the accuracy of the module. The laser ranging sensor 16 and the sensor host 17 are electrically connected. This technology is existing technology and will not be described in detail.

[0030] Two sets of movable slots 18 are respectively opened at the front and rear ends of the top of the support housing 13.

The clamping plate 20 can slide back and forth along the inside of the movable slot 18 to facilitate clamping and fixing the module.

[0031] Specifically, such as Figure 1 and Figure 5As shown, the head end of the rangefinding telescope module is inserted into the telescope port slot 15. When the electric cylinder 19 is activated, the electric cylinder 19 pushes the clamping plate 20 to move along the movable slot 18. The four sets of clamping plates 20 can clamp and fix the rangefinding telescope module without manual operation.

[0032] Working Principle: In use, the ranging telescope module to be tested is first placed on the right side of the positioning plate 14, with its head end inserted into the telescope port slot 15. The tail end of the module is connected to the ranging telescope wiring 22. The ranging telescope module measures the actual distance to the target plate 12 and feeds the result back to the controller host 21 for easy reading. The position of the target plate 12 can be adjusted as needed. The servo motor 3 drives the threaded drive shaft 4 to rotate continuously. The external thread of the threaded drive shaft 4 engages with the internal threaded hole 11 in the internal threaded slider 10, causing the horizontal slider 8 to slide left and right along the horizontal slide rod 6. The position of the target plate 12 changes synchronously, making the testing process more flexible. While the ranging telescope module measures the actual distance to the target plate 12, the laser ranging sensor 16 also measures simultaneously and feeds the result back to the LCD screen of the sensor host 17 for user reference and comparison to determine the module's accuracy. The head end of the rangefinding telescope module is inserted into the telescope port slot 15. The electric cylinder 19 is activated, and the electric cylinder 19 pushes the clamping plate 20 to move along the movable slot 18. The four sets of clamping plates 20 can clamp and fix the rangefinding telescope module without manual operation.
