Description

Technical Field

[0001] This utility model relates to the field of camera pan-tilt technology, and in particular to a camera pan-tilt based on ESP32. Background Technology

[0002] With the rapid development of robotics technology, robot vision, as one of the key technologies for robots to perceive their external environment, plays a crucial role in many fields such as autonomous navigation, target recognition, and human-computer interaction. Robot vision systems acquire image information of the surrounding environment through image acquisition devices such as cameras, and then analyze and process this information using image processing algorithms. This enables robots to perceive and understand their environment, achieving complex functions such as color recognition, scanning and recognizing QR codes, detecting obstacles, and identifying pedestrians, providing vital information support for the intelligent operation of robots.

[0003] However, in existing robot vision implementation solutions, the camera gimbal, as a key component that supports the camera and enables its spatial posture adjustment, directly affects the overall effectiveness of the robot vision system. Currently, widely used camera gimbals generally suffer from several problems that urgently need to be addressed.

[0004] In terms of size, existing camera gimbals are relatively large. This large size not only increases the overall space occupied by the robot, limiting its application in environments with strict space requirements (such as confined indoor spaces and compact production lines), but also increases its weight, affecting its motion performance and flexibility.

[0005] More importantly, in practical use, existing camera gimbals are prone to poor recognition performance. This may be due to an inadequate mechanical structure design of the gimbal, causing camera jitter and misalignment during movement, thus affecting image clarity and stability; or it may be due to insufficient precision in the gimbal's drive system, making it unable to accurately control the camera's attitude adjustment, preventing the camera from accurately pointing at the target object, resulting in recognition failure or reduced accuracy. These problems severely impact the user experience and reduce the practicality and reliability of the robot vision system.

[0006] Therefore, in order to address the problems of large size and poor recognition effect of existing camera gimbals, and to improve the performance of robot vision systems and user experience, it is necessary to improve and innovate camera gimbal devices. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a camera gimbal based on ESP32.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] This utility model embodiment provides a camera pan-tilt head based on ESP32, including: an ESP32 camera module, a fixed bracket, a first drive component, a mounting bracket, and a second drive component. The ESP32 camera module is connected to the fixed bracket. The first drive component is mounted on the mounting bracket and is drivenly connected to the fixed bracket. The second drive component is drivenly connected to the mounting bracket. The first drive component operates to drive the fixed bracket to pitch and rotate, and the second drive component operates to drive the mounting bracket to rotate left and right.

[0010] In one specific embodiment, the ESP32 camera module includes a camera, an ESP32 image transmission module, and an ESP32 communication board. The camera is electrically connected to the ESP32 image transmission module, the ESP32 image transmission module is electrically connected to the ESP32 communication board, and the ESP32 communication board is connected to the fixed bracket.

[0011] In one specific embodiment, the first drive assembly includes a first servo motor and a first servo disk, the first servo disk being connected to the fixed bracket, the first servo motor being mounted on the mounting bracket, and the output shaft of the first servo motor being drively connected to the first servo disk.

[0012] In one specific embodiment, the mounting bracket is disposed inside the fixed bracket, the first servo disk is mounted on the side of the fixed bracket, both the mounting bracket and the fixed bracket are provided with openings corresponding to the output shaft of the first servo motor, and the output shaft of the first servo motor extends out of the openings and is connected to the first servo disk for transmission.

[0013] In one specific embodiment, the mounting bracket is connected to the fixed bracket via a rotating shaft on the side of the mounting bracket away from the first rudder.

[0014] In one specific embodiment, the second drive assembly includes a second servo motor and a second servo disk, the second servo disk being connected to the mounting bracket, and the output shaft of the second servo motor being drively connected to the second servo disk.

[0015] In one specific embodiment, the second servo disk is fixed to the mounting bracket by screws, and the second servo motor is located below the mounting bracket.

[0016] In one specific embodiment, the second rudder is cross-shaped.

[0017] In one specific embodiment, both the first servo and the second servo are 9G digital servos.

[0018] In one specific embodiment, both the fixed bracket and the mounting bracket are made of sheet metal.

[0019] The advantages of this ESP32-based camera gimbal compared to existing technologies are as follows: The first drive component, connected to the fixed bracket, enables the ESP32 camera module to perform stable pitch rotation; the second drive component, connected to the mounting bracket, drives the entire mounting bracket and fixed bracket assembly to rotate left and right. This dual-axis drive design allows the camera to scan and identify the surrounding environment from all directions and multiple angles without changing its own position, ensuring the camera can quickly and accurately capture target image information, greatly improving the accuracy and real-time performance of environmental recognition and effectively enhancing the user experience. Furthermore, the direct connection between the ESP32 camera module and the fixed bracket reduces unnecessary intermediate steps and space waste. The rational installation and transmission design of the first and second drive components minimizes the size of the gimbal while ensuring drive performance. This compact design allows the camera gimbal to easily adapt to various confined spaces, enabling robots to operate flexibly in limited spaces, while reducing the overall load on the robot and improving its motion efficiency and response speed.

[0032] See Figures 1 to 3 The specific embodiment shown in this utility model discloses a camera pan-tilt head based on ESP32, including: an ESP32 camera module, a fixed bracket 40, a first drive component 50, a mounting bracket 60, and a second drive component 70. The ESP32 camera module is connected to the fixed bracket 40. The first drive component 50 is mounted on the mounting bracket 60 and is tractively connected to the fixed bracket 40. The second drive component 70 is tractively connected to the mounting bracket 60. The first drive component 50 operates to drive the fixed bracket 40 to pitch and rotate, and the second drive component 70 operates to drive the mounting bracket 60 to rotate left and right.

[0033] Specifically, by setting slots on both sides of the ESP32 camera module and corresponding buckles on the fixed bracket 40, the slots of the ESP32 camera module and the buckles of the fixed bracket 40 are matched to achieve a stable connection. At the same time, rubber pads are used at the connection point for cushioning to prevent loosening due to vibration and other reasons, ensuring the stability of the ESP32 camera module. In addition, the first drive assembly 50 uses a small stepper motor, which is fixed to the reserved mounting position on the mounting bracket 60 with bolts. A gear is installed on the fixed bracket 40, and a gear meshing with it is installed on the output shaft of the stepper motor, achieving a transmission connection between the stepper motor and the fixed bracket 40 through gear transmission. This connection method has a simple structure, high transmission efficiency, and can precisely control the pitch and rotation of the fixed bracket 40. The second drive assembly 70 also uses a small stepper motor, which is mounted on the robot's main structure or other suitable support components and connected to the transmission wheel on the mounting bracket 60 via a synchronous belt or chain, achieving a transmission connection between the second drive assembly 70 and the mounting bracket 60. Synchronous belt or chain drives have advantages such as smooth transmission, low noise, and the ability to achieve long-distance transmission, which can meet the needs of mounting brackets rotating at around 60 degrees.

[0034] In addition, a rechargeable lithium battery powers the entire camera pan-tilt unit. A battery compartment is installed on the mounting bracket 60, housing the lithium battery and connecting it to the ESP32 camera module, the first drive assembly 50, and the second drive assembly 70 via wires, providing them with the necessary power. Simultaneously, overcurrent and overvoltage protection circuits are incorporated to ensure the safety and stability of the power supply. Furthermore, the ESP32 camera module communicates wirelessly with external devices (such as robot control systems and user terminals) via Wi-Fi or Bluetooth. The ESP32 itself possesses powerful wireless communication capabilities, enabling convenient data exchange with various devices. Through wireless communication, image data captured by the camera module can be transmitted to other devices in real time, while simultaneously receiving control commands from external devices, enabling remote control and operation of the camera pan-tilt unit.

[0035] In other words, the first drive component 50, connected to the fixed bracket 40, enables the ESP32 camera module to perform stable pitch rotation; the second drive component 70, connected to the mounting bracket 60, drives the entire mounting bracket 60 and fixed bracket 40 assembly to rotate left and right. This dual-axis drive design allows the camera 10 to scan and identify the surrounding environment from all directions and multiple angles without changing its own position, ensuring that the camera 10 can quickly and accurately capture target image information, greatly improving the accuracy and real-time performance of environmental recognition, and effectively enhancing the user experience. In addition, the direct connection between the ESP32 camera module and the fixed bracket 40 reduces unnecessary intermediate links and space waste. The reasonable installation and transmission design of the first drive component 50 and the second drive component 70 minimizes the size of the gimbal while ensuring drive performance. This compact design allows the camera gimbal to easily adapt to various confined space environments, enabling the robot to operate flexibly in limited spaces, while reducing the overall load on the robot and improving the robot's motion efficiency and response speed.

[0036] In one embodiment, the ESP32 camera module includes a camera 10, an ESP32 image transmission module 20, and an ESP32 communication board 30. The camera 10 is electrically connected to the ESP32 image transmission module 20, the ESP32 image transmission module 20 is electrically connected to the ESP32 communication board 30, and the ESP32 communication board 30 is connected to the fixed bracket 40.

[0037] Specifically, a small, high-resolution camera 10, such as the OV2640 camera, is selected. Interface pins are provided on the camera 10. The image data output pins of the camera 10 (e.g., the data lines of the DVP interface) are connected to the corresponding image input pins of the ESP32 image transmission module 20 (e.g., the ESP32-CAM module) using DuPont wires. Simultaneously, the power supply pins (VCC and GND) of the camera 10 are connected to the power supply pins of the ESP32 image transmission module 20 to ensure that the camera 10 can be powered normally. During the connection process, insulating tape is used to wrap the connection points to prevent short circuits. In terms of layout, the camera 10 and the ESP32 image transmission module 20 are placed as close as possible to reduce the length of the image data transmission lines and reduce signal interference. For example, they can be mounted on a custom-made small PCB board and connected via traces on the PCB board.

[0038] The ESP32 image transmission module 20 and the ESP32 communication board 30 (using an ESP32 development board) are connected via serial communication. The UART interfaces (such as TXD and RXD) of the ESP32 image transmission module 20 are connected to the corresponding UART interfaces of the ESP32 communication board 30, and their ground wires (GND) are also connected. To enhance signal stability, resistors can be added to the serial lines for impedance matching. In terms of hardware layout, considering the space and structure of the mounting bracket 40, the ESP32 communication board 30 is installed in a suitable position on the bracket 40 and secured with screws or clips. The ESP32 image transmission module 20 is then connected to the ESP32 communication board 30 via a flexible printed circuit board (FPC), wires, or plug-ins, ensuring reliable and flexible connection.

[0039] In other words, the ESP32 image transmission module 20 possesses powerful image processing and transmission capabilities, enabling efficient encoding and compression of image data acquired by the camera 10. This reduces data transmission volume and improves transmission efficiency while maintaining image quality. For example, using the JPEG encoding algorithm, image data can be compressed to 1 / 10-1 / 20 of its original size without significantly reducing image quality. Furthermore, the ESP32 communication board 30 supports multiple network connection methods, such as Wi-Fi and Bluetooth, allowing for stable network connections with external devices. Even in complex network environments, it ensures real-time and stable transmission of image data, avoiding issues such as image stuttering or loss. Additionally, the ESP32 communication board 30 offers excellent compatibility and scalability, facilitating easy integration with other devices. For instance, it can connect to robot sensors and actuators to achieve more complex intelligent functions. Moreover, due to the open-source nature and abundant software resources of ESP32, users can upgrade and optimize the software according to their actual needs, continuously expanding the functionality of the camera pan-tilt unit. The ESP32 communication board 30 supports multiple communication protocols, enabling the camera pan-tilt unit to communicate with different types of external devices. Whether it's simple serial communication or complex network communication, it can be easily implemented, providing users with more choices and flexibility.

[0040] In one embodiment, the first drive assembly 50 includes a first servo motor 51 and a first servo disc 52, the first servo disc 52 being connected to the fixed bracket 40, the first servo motor 51 being mounted on the mounting bracket 60, and the output shaft of the first servo motor 51 being drively connected to the first servo disc 52.

[0041] Specifically, the first servo disc 52 is bolted to the pre-drilled mounting holes of the mounting bracket 40, ensuring a secure connection between the first servo disc 52 and the mounting bracket 40 without any looseness. Then, the first servo motor 51 is placed into the mounting slot of the mounting bracket 60 and secured to the mounting bracket 60 using its own mounting screws. During installation, pay attention to the direction of the output shaft of the first servo motor 51 to ensure correct connection with the first servo disc 52. Next, insert the output shaft of the first servo motor 51 into the shaft hole of the first servo disc 52, ensuring a tight fit between the output shaft and the servo disc shaft hole. If there is a gap between the output shaft and the shaft hole, apply a suitable amount of grease to the shaft hole to reduce friction and noise during transmission. Furthermore, by controlling the rotation angle of the first servo motor 51 through software, precise control of the pitch and rotation position of the ESP32 camera module can be achieved. Users can position the ESP32 camera module at any angle according to actual needs to meet different shooting angle requirements. For example, in robot vision applications, the ESP32 camera module can be adjusted to a specific pitch angle for better target object capture. Furthermore, the rotational speed of the first servo motor 51 can be adjusted via the pulse width of the control signal, thereby controlling the pitch rotation speed of the ESP32 camera module. Users can select appropriate movement speeds according to different application scenarios, such as fast scan mode or slow tracking mode.

[0042] In other words, the first drive assembly 50 adopts a combination of a first servo motor 51 and a first servo disc 52, which is simple in structure and easy to install. The first servo disc 52 is directly connected to the fixed bracket 40, and the first servo motor 51 is fixed to the mounting bracket 60. The pitch rotation of the ESP32 camera module is realized through the transmission connection between the output shaft of the first servo motor 51 and the first servo disc 52, reducing the number of mechanical transmission parts and lowering the system complexity and failure rate. In addition, the first servo disc 52 is fixed to the fixed bracket 40 and the first servo motor 51 is fixed to the mounting bracket 60 by bolts, ensuring that the connection between the components is firm and reliable. During operation, there will be no loosening or falling off, ensuring the stability and safety of the ESP32 camera module.

[0043] In one embodiment, the mounting bracket 60 is disposed inside the fixed bracket 40, the first servo disk 52 is mounted on the side of the fixed bracket 40, both the mounting bracket 60 and the fixed bracket 40 are provided with openings corresponding to the output shaft of the first servo motor 51, and the output shaft of the first servo motor 51 extends out of the openings and is connected to the first servo disk 52 for transmission.

[0044] Specifically, the mounting bracket 60 is located inside the fixed bracket 40. This nested design makes the entire drive assembly more compact in space. Within the limited space, other related components, such as the ESP32 camera module and power supply module, can be better arranged, improving the overall integration of the equipment. Compared to traditional independent installation methods, this design reduces the horizontal space occupied by the mounting bracket 60 and fixed bracket 40, making the equipment smaller, lighter, and easier to carry and install. Furthermore, the output shaft of the first servo motor 51 passes through openings in both the mounting bracket 60 and the fixed bracket 40 and is connected to the first servo disc 52. This design provides dual positioning for the output shaft during transmission, reducing output shaft wobble and offset, and improving transmission stability and accuracy. Due to the supporting effect of the mounting bracket 60 and fixed bracket 40 on the output shaft, the transmission system can better maintain stable operation when subjected to external disturbances (such as vibration and impact), reducing transmission errors caused by disturbances.

[0045] In one embodiment, the mounting bracket 60 is connected to the fixed bracket 40 via a rotating shaft 80 on the side of the mounting bracket away from the first rudder disk 52.

[0046] Specifically, since the mounting bracket 60 is connected to the fixed bracket 40 via the rotating shaft 80, when the first servo motor 51 drives the fixed bracket 40 to pitch and rotate, the rotating shaft 80 can provide support and guidance, effectively reducing the interference of external factors (such as vibration, wind, etc.) on the mounting bracket 60, allowing the mounting bracket 60 to remain stable and not move with the fixed bracket 40. Furthermore, the connection method of the rotating shaft 80 allows the mounting bracket 60 and the fixed bracket 40 to form a relatively independent structural system in space, making the overall system structure more rational. The mounting bracket 60 can function as an independent module, facilitating the installation and layout of other components, and also simplifying the maintenance and upgrades of the entire system. This connection method ensures that the movements of the mounting bracket 60 and the fixed bracket 40 are independent, reducing mutual interference and influence between components. Even if the fixed bracket 40 experiences minor deviations during movement, it will not affect the stability of the mounting bracket 60, thereby improving the reliability and stability of the entire system.

[0047] In one embodiment, the second drive assembly 70 includes a second servo motor 71 and a second servo disk 72, the second servo disk 72 being connected to the mounting bracket 60, and the output shaft of the second servo motor 71 being drively connected to the second servo disk 72.

[0048] Specifically, the second servo motor 71 drives the mounting bracket 60 to rotate left and right, enabling the ESP32 camera module to rotate at a large angle in the left and right directions, thereby expanding the shooting range of the camera 10. For example, by controlling the second servo motor 71 to rotate to different angles, the camera 10 can capture scenes from different directions, meeting various shooting needs. In practical applications, such as monitoring systems and robot vision scenarios, the camera 10 needs to be able to flexibly adjust the shooting angle according to the actual situation. In addition, the direct connection between the second servo motor 72 and the mounting bracket 60 allows the power of the second servo motor 71 to be directly transmitted to the mounting bracket 60, reducing energy loss and vibration during power transmission. At the same time, the stable structure of the mounting bracket 60 also provides good support for the ESP32 camera module, reducing vibration and swaying of the ESP32 camera module during movement and improving the stability of the captured images.

[0049] The first servo motor 51 and the second servo motor 71 operate relatively independently and will not interfere with each other.

[0050] In one embodiment, the second servo disc 72 is fixed to the mounting bracket 60 by screws, and the second servo motor 71 is located below the mounting bracket 60.

[0051] Specifically, the second servo motor 71 is placed below the mounting bracket 60, and the second servo disc 72 is fixed to the mounting bracket 60 with screws. This layout makes full use of the space below the mounting bracket 60, avoiding the second servo motor 71 occupying additional space in the horizontal direction, thereby reducing the overall size of the system. For example, in applications with high space requirements, such as small robots and drones, this design makes the equipment more compact, easier to carry and install. In addition, the smaller size makes the system easier to integrate with other devices or systems. For example, in intelligent security monitoring systems, the camera pan-tilt unit can be integrated into smaller monitoring devices, enabling more flexible installation and deployment. Furthermore, the second servo disc 72 is fixed to the mounting bracket 60 with screws, which is more secure than other connection methods (such as snap-fit ​​connections), reducing the relative movement between the second servo disc 72 and the mounting bracket 60, thereby improving the structural stability of the entire system.

[0052] In one embodiment, the second rudder disk 72 is cross-shaped.

[0053] Specifically, the cross-shaped design allows the second servo disc 72 to better resist bending deformation when subjected to the torque load of the second servo motor 71. Compared with traditional round or square servo discs, the cross-shaped servo disc can increase its bending strength by 20%-30% under the same material and size conditions. For example, when the servo motor rotates at high speed, the servo disc can maintain a stable shape and will not affect the motion accuracy of the camera module due to bending deformation.

[0054] In one embodiment, both the first servo 51 and the second servo 71 are 9G digital servos.

[0055] Specifically, using 9G digital servos as the first servo 51 and the second servo 71 has advantages such as low cost, high performance, compact structure, and strong compatibility, and can meet the motion control needs of most small automated equipment.

[0056] In one embodiment, both the fixed bracket 40 and the mounting bracket 60 are made of sheet metal.

[0057] Specifically, sheet metal materials have high strength and rigidity. Combined with reasonable structural design, such as reinforcing ribs and modular design, they can effectively improve the bending, torsion and impact resistance of the fixed bracket 40 and the mounting bracket 60, ensuring that the system can maintain stable operation under various working conditions.

[0058] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
