Description

Technical Field

[0001] This invention relates to the field of camera technology, and in particular to a camera calibration system, method, and electronic device with gyroscope functionality. Background Technology

[0002] Currently, cameras include automotive cameras, robot cameras, industrial drone cameras, action cameras, etc. Most of these types of camera products need to have functions such as measuring acceleration, angular velocity, and image stabilization. Therefore, these types of camera products require the use of gyroscope sensors.

[0003] In related technologies, if the acceleration, direction, angular velocity, and other related parameters of a camera with a gyroscope sensor are inaccurate before leaving the factory, it will seriously affect the use and safety of the camera product. Therefore, cameras with gyroscope sensors need to be calibrated before leaving the factory. However, at present, different cameras have different calibration methods. When there are many different types of cameras, multiple different calibration test boards need to be designed, which is costly and has poor compatibility. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a camera calibration system, method and electronic device with gyroscope function, which can be used to calibrate and test a variety of different types of cameras with gyroscope sensor function.

While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0025] Currently, if the acceleration, direction, angular velocity, and other related parameters of a camera with a gyroscope sensor are inaccurate before leaving the factory, it will seriously affect the use and safety of the camera product. Therefore, cameras with gyroscope sensors need to be calibrated before leaving the factory. However, different cameras currently use different calibration methods. When there are many different types of cameras, multiple different calibration test boards need to be designed, which is costly and has poor compatibility.

[0026] To address the aforementioned issues, this application provides a camera calibration system, method, and electronic device with gyroscope functionality, which can be used as a test board compatible with various types of cameras equipped with gyroscope sensors for calibration.

[0027] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0028] The first aspect of this application provides a camera calibration system with a gyroscope function, including: a main control module 100, a power supply module 200, a DIP switch module 300, an interface module 400, and a communication module 500. The main control module 100 is used to write various calibration algorithms; the power supply module 200 is electrically connected to the main control module 100 and is connected to an external DC power supply to power the main control module 100; the DIP switch module 300 is electrically connected to the main control module 100 and is used to switch codes to match the calibration algorithms; the interface module 400 is electrically connected to both the main control module 100 and the power supply module 200, and is used to connect a camera module so that the camera module can be connected to the main control module 100; the communication module 500 is electrically connected to the main control module 100 and is used to drive the main control module 100 to run the calibration algorithms.

[0029] It should be noted that the main control module 100 is an MCU processor, and its various calibration algorithms are matched with the models of various camera modules. The power supply module 200 is used to connect an external DC 12V power supply. The DIP switch module 300 toggles different bits of the switch to form 0 or 1 binary codes. The DIP switch in this application has 6 bits, and the encoding range is 0 to 63, which is 2 to the power of 6. If the first bit is turned ON and the other bits remain unchanged, the code is 000001. Therefore, it can be compatible with 64 different types of gyroscope sensor models based on the 6-bit DIP switch settings. Similarly, the number of bits of the DIP switch can be selected according to the number of gyroscope sensor types that need to be compatible. The interface module 400 is connected to the camera module via a wired connection. The communication module 500 is used to drive the main control module 100 to run the calibration algorithm corresponding to the model of the camera module according to the encoding of the DIP switch module 300.

[0030] Please see Figure 1 In one embodiment, the DIP switch module 300 includes multiple switch units, each of which is electrically connected to the main control module 100.

[0031] It should be noted that this application has 6 switch units, all of which can be toggled.

[0032] Please see Figure 1 In one embodiment, the interface module 400 includes a connector that is electrically connected to both the main control module 100 and the power module 200. Specifically, the interface module 400 also includes a connecting cable that is electrically connected to the connector.

[0033] It should be noted that the connecting cable can be a USB cable or a Type-C cable. The connecting cable is used to connect the camera module to the connector so that the power module 200 supplies power to the camera module and puts it into working condition.

[0034] Please see Figure 1 In one embodiment, the communication module 500 includes a USB connector electrically connected to the main control module. Specifically, the communication module 500 further includes a terminal electrically connected to the USB connector. Specifically, the USB connector has a first port. Specifically, the USB connector also has a second port.

[0035] It should be noted that the terminal generally refers to the PC, and the USB connector is the medium for communication between the main control module 100 and the terminal. The first port is the port on the main control module, and the second port is the port on the terminal; the two are connected via a USB cable.

[0036] The above method enables compatibility of multiple camera module models on a single calibration board, reducing production costs and improving work efficiency.

[0037] Please see Figure 2 The second aspect of this application provides a camera calibration method with gyroscope functionality, applied to a camera calibration system with gyroscope functionality, comprising:

[0038] Step S101: Connect an external power supply to the power module to supply power to the main control module.

[0039] It should be noted that the camera calibration system with gyroscope function is set on a calibration board, and the power module is connected to an external DC 12V power supply to keep the calibration board in normal working condition.

[0040] Step S102: The camera module is connected to the connector via a connecting cable so that the power module supplies power to the camera module.

[0041] It should be noted that the camera module is connected to the connector via a connecting cable, and the power module supplies power to the camera module via the connecting cable, enabling the camera module to be in working condition.

[0042] Step S103: Based on the model of the camera module, toggle multiple switch units accordingly to output encoded information.

[0043] It should be noted that the operator can obtain the coding information of the camera module by toggling multiple switch units according to the model of the camera module.

[0044] Step S104: The terminal sends the calibration algorithm to the main control module via the USB connector according to the encoding information to perform calibration testing on the camera module.

[0045] It should be noted that after the calibration board is set with the camera module model, it is connected to the terminal via the USB connector. The terminal's host computer software then instructs the main control module to perform calibration tests based on the obtained camera module model. Finally, according to the terminal's calibration algorithm and the calibration board's main control module, the final calibration data is written to the camera module via the calibration board's connection cable.

[0046] The above method enables compatibility of multiple camera module models on a single calibration board, reducing production costs and improving work efficiency.
