Description

Technical Field

[0001] This utility model relates to a high-definition motion video acquisition system for tiny insects, belonging to the field of biological motion data acquisition technology. Background Technology

[0002] Current biological motion capture technologies, including Vicon optical systems, inertial sensor solutions, and depth camera solutions, are widely used in human and large animal research. However, their technological framework faces significant adaptation barriers when applied to tiny insects. Tiny insects are small in size and move at high frequencies, making it difficult for mainstream optical sensors and lidar systems to capture the details of their movements due to resolution limitations. Furthermore, tiny insects cannot carry sensors, further restricting the application of technologies such as inertial measurement.

[0003] Existing solutions for capturing the movement of tiny insects still have core shortcomings: 1) Fixed surround shooting devices (such as patent CN218599252U), although capable of recording the static morphology of insects from multiple angles, have a narrow field of view and lack dynamic tracking capabilities, making them unsuitable for capturing insect movement over a wide field of view; 2) While high-speed, high-definition cameras can be used for large-scale, high-precision insect movement capture, they are expensive and their acquisition time is severely limited; 3) Camera array systems (such as "Uneven substrates constrain walking speed in ants through modulation of stride frequency more than stride length," GT Clifton, D. Holway and N. Gravish, Royal Society Open Science, 2020-03-25) rely on multi-device deployment and complex image stitching algorithms, resulting in high deployment costs and poor real-time performance; 4) Industrial-grade motion capture systems (such as "Autonomous tracking of honey bee behaviors over long-term periods with cooperating robots," Jiří Ulrich, Martin Stefanec, etc., Science) Robotics (2024-10-16) can drive a camera to track targets via a guide rail, but the equipment is bulky, complex to operate, and relies on high-performance recognition algorithms, resulting in extremely high hardware costs. None of the above solutions can simultaneously meet the three core requirements of high precision, wide coverage, and low cost. Utility Model Content

[0004] This invention addresses the shortcomings of the existing technology by providing a high-definition motion video acquisition system for tiny insects.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A high-definition motion video acquisition system for tiny insects includes an outer frame, within which a slidingly connected experimental platform is provided. A camera is mounted on top of the experimental platform and a light panel is mounted below it. The camera is connected to the outer frame via an inner frame.

[0006] Furthermore, the inner frame is provided with a symmetrically arranged Y-axis, the Y-axis is provided with a slidably connected X-axis, the X-axis is provided with a slidably connected camera bracket, and the camera is installed below the camera bracket.

[0007] Furthermore, the inner frame is provided with a driving device for driving the X-ray axis to slide along the Y-ray axis. The driving device includes a stepper motor and an optical axis bracket respectively disposed at both ends of the Y-ray axis. The stepper motor drives the X-ray axis to slide along the Y-ray axis through a synchronous belt and the optical axis bracket.

[0008] Furthermore, both ends of the X-axis are provided with Y-axis sliders that are slidably connected to the Y-axis.

[0009] Furthermore, the camera bracket is provided with an X-axis slider that is slidably connected to the X-ray axis.

[0010] Furthermore, the camera bracket is equipped with a height adjustment mechanism for adjusting the height of the camera and a cable drag chain mounting groove for neat cable layout.

[0011] Furthermore, the inner frame is provided with symmetrically arranged slide rails, and the slide rails are provided with slidably connected trolleys, and the experimental platform is slidably connected to the slide rails via the trolleys.

[0012] Furthermore, the trolley is equipped with pulleys that are slidably connected to the slide rail.

[0013] Furthermore, a bottom electrical box connected to the bottom of the outer frame is provided below the lamp panel.

[0014] Furthermore, the experimental platform is made of transparent material.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application uses a stepper motor to drive a synchronous belt to move the X-axis along the Y-axis, and a camera bracket to move the camera along the X-axis, thereby locating the insect's center point in real time and ensuring that the target is always within the camera's field of view, achieving large-scale dynamic tracking and high-definition video acquisition of micro-insects. The use of a light panel and a transparent experimental platform allows for rapid sample replacement and uniform light transmission, ensuring high-definition video acquisition. It offers significant advantages in terms of low cost, large-area coverage, micro-insect adaptability, and high-definition motion video acquisition, making it suitable for fields such as insect behavior research and biomimetic robot development. This application provides a high-quality, efficient, and economical solution for the study of micro-insect movement behavior. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] like Figures 1-4As shown, a high-definition motion video acquisition system for tiny insects includes an outer frame 1. An experimental platform 6 is slidably connected within the outer frame 1. A movable camera 12 is mounted above the experimental platform 6, and a light panel 7 is mounted below it. The camera 12 is connected to the outer frame 1 via an inner frame 5. The inner frame 5 provides overall support and protection for the camera 12 and its moving mechanism. The movable camera 12 is mounted on a low-cost two-degree-of-freedom linear slide rail. A real-time target detection algorithm dynamically locates the insect's position, driving the camera 12 to keep the target centered in the frame, overcoming the narrow field of view limitations of traditional fixed-position systems.

[0024] The inner frame 5 is provided with a symmetrically arranged Y-axis 3, and an X-axis 2 is slidably connected to the Y-axis 3. A camera bracket 14 is slidably connected to the X-axis 2, and the camera 12 is mounted below the camera bracket 14. The X-axis 2 and Y-axis 3 are used to drive the camera 12 to move, enabling the camera 12 to move freely in a two-dimensional plane. The camera 12 is fixed to the X-axis slider 15 by the camera bracket 14, and the X-axis slider 15 drives the camera 12 to achieve free movement.

[0025] The inner frame 5 is provided with a driving device for driving the X-axis 2 to slide along the Y-axis 3. The driving device includes a stepper motor 4 and an optical axis bracket 13 respectively set at both ends of the Y-axis 3. The stepper motor 4 drives the X-axis 2 to slide along the Y-axis 3 through the synchronous belt 16 and the optical axis bracket 13.

[0026] Both ends of the X-axis 2 are provided with Y-axis sliders 11 that are slidably connected to the Y-axis 3.

[0027] The camera bracket 14 is provided with an X-axis slider 15 that is slidably connected to the X-axis 2.

[0028] The X-axis slider 15 and Y-axis slider 11, together with the synchronous belt 16, form a lightweight motion platform that supports the camera 12 to move freely in a two-dimensional plane.

[0029] The camera bracket 14 is equipped with a height adjustment mechanism for adjusting the height of the camera 12 and a cable drag chain mounting groove for neat cable layout.

[0030] The inner frame 5 is provided with symmetrically arranged slide rails 9, and trolleys 10 are slidably connected to the slide rails 9. The experimental table 6 is slidably connected to the slide rails 9 via the trolleys 10. The trolleys 10 are provided with pulleys 17 that are slidably connected to the slide rails 9. The experimental table 6 can be moved back and forth and pulled out through the slide rails 9, trolleys 10 and pulleys 17, so as to facilitate the placement or replacement of insect samples.

[0031] Below the light panel 7 is a bottom electrical box 8 connected to the bottom of the outer frame 1. The light panel 7 provides uniform transmitted illumination to ensure high-definition image acquisition.

[0032] The experimental platform 6 is made of transparent material. The experimental platform 6 is made of transparent acrylic and can move back and forth along the slide rail 9, supporting quick replacement of insect samples.

[0033] like Figure 5 As shown, the insect identification and tracking algorithm includes a target detection algorithm and a motion control algorithm. The target detection algorithm calculates the insect's position in real time through low-pass filtering, adaptive binarization, morphological processing, contour extraction, minimum bounding rectangle (MBR) localization, and center point extraction. The motion control algorithm includes error calculation and PID control. Based on the deviation between the insect's center point and the center position of the camera 12, the speed and direction of the stepper motor 4 are dynamically adjusted so that the camera 12 moves towards the insect, thereby achieving continuous tracking of the insect.

[0034] Through hardware-algorithm co-design, large-scale dynamic tracking and high-definition video acquisition of tiny insects are achieved at low cost, with simultaneous shooting and tracking, eliminating the need for GPU computing power. The PID control algorithm uses real-time feedback of insect position deviation to control stepper motor 4 for smooth tracking, preventing target loss. The target detection algorithm abandons training-based image segmentation methods, adopting a lightweight traditional image processing workflow, significantly reducing computing power requirements and ensuring the system can run in real-time on embedded devices without a GPU. This hardware-algorithm co-design overcomes the narrow field of view limitations of traditional macro systems, enabling a single camera to cover a large monitoring area of ​​≥0.5m × 0.5m, while simultaneously meeting the requirements of high precision and low cost.

[0035] This application utilizes a stepper motor 4 to drive a synchronous belt 16, which in turn moves the X-axis 2 along the Y-axis 3. A camera bracket 14 then moves the camera 12 along the X-axis 2, allowing for real-time positioning of the insect's center point and ensuring the target remains within the camera 12's field of view. This enables large-scale dynamic tracking and high-definition video acquisition of micro-insects. The use of a light panel 7 and a transparent experimental platform 6 facilitates rapid sample replacement and uniform light transmission, ensuring high-definition video acquisition. This application offers significant advantages in terms of low cost, wide coverage, micro-insect adaptability, and high-definition motion video acquisition, making it suitable for insect behavior research and biomimetic robot development. This application provides a high-quality, efficient, and economical solution for the study of micro-insect movement behavior.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
