Description

Technical Field

[0001] This invention belongs to the field of visual perception technology, and particularly relates to a method and system for calibrating visual perception areas. Background Technology

[0002] In modern intelligent surveillance, autonomous driving, and industrial automation, cameras serve as core sensing devices, undertaking crucial tasks such as real-time environmental information acquisition, target recognition, and tracking. However, the camera's visual perception area is affected by various factors, such as the device's installation location, angle changes, and lens distortion. These factors can cause the camera's perception area to deviate from its intended position, thereby affecting image quality and recognition accuracy.

[0003] Calibrate the camera's visual perception area, a crucial step in ensuring the stable and accurate operation of a vision system. As cameras are increasingly used in complex environments, the area they need to cover often undergoes significant dynamic changes, especially during extended operation or exposure to physical impacts (such as collisions and vibrations). In these situations, the camera's mounting angle, focal length, and field of view may shift. Therefore, effective visual perception area calibration is essential to restore and optimize the camera's sensing accuracy.

[0004] Although some cameras can refocus the image to a certain extent, they still cannot automatically reset when unattended, and rely heavily on on-site operations by maintenance personnel. Summary of the Invention

[0005] Based on this, the present invention aims to propose a visual perception area calibration method and system, which utilizes the optical transmission port of an intelligent camera to sense the collision vibration of the camera's visual perception area, automatically refocuses, and resets the camera's visual perception area.

[0024] Refocus optically based on pre-configured information;

[0025] Resetting the visual perception area ensures that the camera's visual image meets the preset perception conditions.

If the reset visual offset angle does not exceed the preset allowable offset value, the configuration information of the current visual perception area is stored. Otherwise, the step of resetting the visual offset angle of the visual perception area is repeated until the number of resets reaches the preset value.

[0029] Furthermore, the polarization characteristics of an optical signal include light attenuation, phase, wavelength, polarization, mode field distribution, and propagation time.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] See Figure 1 An embodiment of the present invention provides a visual perception area calibration system, including an optical access and sensing module 102, an offset analysis module 104, and an optical calibration module 106.

[0046] The optical access and sensing module 102 is used to acquire polarized light information;

[0047] The offset analysis module 104 is used to determine the camera's viewing angle offset information based on the polarized light information;

[0048] The optical calibration module 106 is used to calibrate the camera's visual perception area based on the viewing angle offset information.

[0049] Specifically, the optical access and sensing module 102 is responsible for collecting optical signals from the environment and transmitting them to subsequent analysis and processing modules. It acquires polarized light information through optical sensors and provides image or data input for further system analysis. For example, it acquires light intensity information in different directions using polarization filters or polarization arrays to record polarization characteristics in the image; or it collects environmental information such as illumination intensity and reflectivity within the camera's field of view to construct the optical features of the image. Furthermore, it can be combined with a traditional image acquisition module to acquire ordinary or multi-channel image data. The polarized light information acquired by the optical access and sensing module 102 can include optical parameters such as the degree of polarization and polarization angle of the optical signal.

[0050] The offset analysis module 104 receives optical signal data from the optical access and sensing module 102 and performs offset analysis to detect changes in the camera's viewing angle or the shift in the sensing area. Its goal is to identify the camera's angular deviation and calculate the resulting change in the visual area. In a specific embodiment, it is responsible for connecting the camera to the video network platform, receiving pre-configuration information for vibration sensing from the video network platform, and calculating the viewing angle offset based on the polarization light information fed back by the optical access and sensing module 102 according to the pre-configuration information.

[0051] The optical calibration module 106 performs automatic calibration of the camera based on the detection results of the offset analysis module 104, ensuring that its visual perception area returns to normal. This module can adjust the position and angle of the camera based on error feedback, or perform compensation in image processing. Specifically, it can restore the normal visual perception area through visual adjustments in physical position, such as adjusting the physical position or angle of the camera; or it can perform compensation from the image, such as through image processing algorithms (e.g., perspective transformation, distortion correction, etc.), to correct the visual deviation caused by the angle change.

[0052] See Figure 2 An embodiment of the present invention provides a visual perception region calibration method, comprising the following steps:

[0053] Step S210. Obtain polarized light information.

[0054] The polarization information obtained in this step includes the polarization state of the light signal, which helps to analyze changes in the camera's viewing angle and sensing area. Polarizing filters or polarization arrays can be used to capture the light intensity distribution in different directions (horizontal, vertical, or 45 degrees, etc.), collect the polarization intensity (DoP) and polarization angle (AoP) in the scene, and convert them into image data to generate a polarization image.

[0055] In a further embodiment, step S210 includes the following steps:

[0056] Step S211. Acquire real-time optical signals.

[0057] This step can acquire light signals in the scene in real time through sensor or camera systems, especially optical phenomena caused by reflection and scattering. These light signals contain key information about scene objects and their surface characteristics. For the detection of polarized light, it is first necessary to acquire light signals with different directions and different polarization states.

[0058] Step S212. Extract the polarization characteristics of the optical signal.

[0059] Specifically, the polarization characteristics of an optical signal include light attenuation, phase, wavelength, polarization, mode field distribution, and propagation time. A more preferred embodiment may perform some preprocessing on the optical signal, such as signal amplification and noise reduction, before extracting the polarization characteristics of the optical signal.

[0060] Step S220. Determine the camera's offset state based on the polarized light information.

[0061] This step can acquire the time-series data of the polarization characteristics of the optical signal, perform time-frequency transformation to calculate the feature transformation value, compare the feature transformation value with a preset threshold, generate vibration state results, and determine the camera offset state based on the vibration state results.

[0062] Specifically, by performing time-frequency transformation on the polarization characteristics of the acquired light signal, the temporal and frequency characteristics of the signal are extracted. These characteristics help reveal the changes in the light signal across different time scales and frequency ranges, thus allowing the system to react to whether the camera is vibrating or experiencing other dynamic changes. Preset vibration thresholds are typically based on experimental data or normal operating conditions of the scene, set as boundaries that distinguish between vibration and stationary states. Examples include frequency fluctuation thresholds, energy change thresholds, and amplitude change thresholds. The calculated feature transformation values ​​are compared with the preset thresholds to determine if they exceed the vibration threshold. If the threshold is exceeded, the camera is considered to be in a vibrating state; otherwise, it is considered to be stationary. Vibration state can indicate whether the camera has shifted, while shift state describes changes in the camera's angle or the shift of its visual area. The camera's vibration state is usually related to its physical shift; for example, strong vibration may cause a shift in the camera's field of view, while slight vibration may only affect image quality but not necessarily cause a significant shift.

[0063] In terms of examples, the vibration status is represented by two values: True and False. If the result is True, it means that the camera is vibrating and has affected normal visual perception. If the result is False, it means that the camera is vibrating but has not affected normal visual recognition. In this case, light signal monitoring can continue and the camera's viewing angle can be adjusted temporarily.

[0064] Step S230. Calibrate the camera's visual perception area according to the offset state.

[0065] After determining the offset state, the camera's visual perception area is calibrated based on the analysis results. This process may include adjusting the camera's position and angle, or correcting the visual perception area using image compensation techniques. For example, if the camera is adjustable (e.g., a pan-tilt camera), the camera's pitch and horizontal angles are adjusted according to the offset to restore the correct viewing angle; if the camera cannot be physically adjusted, image processing algorithms can be used to correct deviations in the image, such as perspective transformation and image correction. Geometric correction is performed using the camera's intrinsic and extrinsic parameters, combined with the offset state. If there are continuous dynamic changes in the environment (such as vibration or collision), real-time polarized light information can be used to continuously calibrate and correct the camera, ensuring that the perception area remains accurate.

[0066] Specifically, when the offset state indicates that vibration is affecting the camera's visual perception, the following visual perception area calibration is performed:

[0067] Obtain pre-configuration information for the visual perception region;

[0068] Refocus optically based on pre-configured information;

[0069] Resetting the visual perception area ensures that the camera's visual image meets the preset perception conditions.

[0070] Before performing any calibration operations, it is necessary to obtain the camera's pre-configuration information under normal conditions. This includes parameters of the camera's visual perception area and the set values ​​that meet the perception requirements under standard operating conditions, such as field of view, focal length, resolution, sensitivity, and lens distortion correction parameters. After obtaining the pre-configuration information,

[0071] The optical focus is re-established based on the pre-configured information to restore the camera's optimal imaging performance. Vibration or shifting can cause the camera's focus to shift, thus requiring lens readjustment. Optical focusing can employ autofocus systems, manual focus, focus algorithms, etc.

[0072] After optical focusing is complete, the camera's visual perception area needs to be reset to ensure that the camera's angle of view, focus, exposure, and other settings are restored to normal working condition and meet the preset perception conditions. Specifically, the camera's field of view is reset through mechanical adjustment or digital zoom to ensure that the camera can capture the predetermined area. For example, if vibration causes the camera's field of view to shift, resetting the field of view can ensure that the camera refocuses on the important area; the camera lens may shift or lose stability due to vibration, so it is necessary to adjust the lens stability through sensor feedback to restore the original perception area; if vibration causes image distortion, the camera needs to use its built-in image processing algorithm to correct the image distortion and ensure that the image conforms to the expected geometric shape.

[0073] In a further embodiment, resetting the visual perception area so that the camera's visual image meets preset perception conditions includes:

[0074] Reset the visual offset angle of the visual perception area;

[0075] The reset visual offset angle is compared with the preset allowable offset value. If the reset visual offset angle does not exceed the preset allowable offset value, the configuration information of the current visual perception area is stored. Otherwise, the step of resetting the visual offset angle of the visual perception area is repeated until the number of resets reaches the preset value.

[0076] The deviation angle of the camera's visual area often has a standard value. By using a large amount of data, the curve of polarization characteristic frequency and viewing angle offset can be obtained. By comparing the reset visual offset angle with the preset offset allowable value, the offset angle of the camera can be adjusted to be within the allowable range to obtain the ideal visual area.

[0077] Specifically, after the reset process, the camera angle is compared with the initial angle or the predetermined target angle to calculate the actual offset. The current reset visual offset angle is then compared with a preset allowable offset value. For example, if the offset angle is greater than the preset value, the reset is considered unsuccessful and readjustment is required. When the reset visual offset angle meets the preset allowable offset value, the system saves the current visual perception area configuration for later use. If the comparison reveals that the reset visual offset angle exceeds the preset allowable offset value, the reset process needs to be repeated until the preset maximum number of resets is reached. The system typically sets a maximum number of resets to prevent the system from entering an infinite loop. This number is set based on the actual needs of the application and the characteristics of the device, such as 3, 5, or 10 times. After each adjustment, the angle is compared again until the conditions are met or the reset limit is reached. If the reset count reaches the preset value, the system can take other measures, such as reminding the user to check the camera hardware or performing manual intervention, or entering a fault handling mode.

[0078] The above embodiments provide a visual perception area calibration method, which determines whether the camera's vibration status affects the visual recognition function by using light signals. Specifically, it determines the camera's viewing angle offset information based on polarized light information, and calibrates the camera's visual perception area according to the offset status. Through system integration, it realizes whether the camera has a visual offset due to vibration, thereby automatically resetting the visual perception area without the need for on-site operation by maintenance personnel, thus improving the user experience.
