Description

Technical Field

[0001] The present invention relates to the technical field of head-mounted shooting equipment, and in particular to a quick shooting method, quick shooting device, glasses and computer equipment based on multi-sensor collaboration. Background Art

[0002] With the increasing popularity of camera functionality in smart glasses, users are increasingly demanding faster snapshots. However, existing camera glasses have significant drawbacks. They rely on CMOS sensors to independently collect ambient light parameters (such as light intensity and color temperature). This results in a dynamic calibration time of 300-500ms upon camera startup, severely limiting response speed. While some solutions use ASL ambient light sensors to assist in detecting light intensity, these sensors cannot independently detect key parameters such as color temperature, infrared light intensity, and light frequency. Consequently, core parameters such as white balance and exposure time still require secondary calibration with the CMOS sensor. Existing single-sensor solutions suffer from high white balance calibration errors in mixed light source scenarios (such as indoor fluorescent lighting and natural light from a window), which can easily lead to color distortion. Furthermore, traditional interactive methods such as vibration triggering and voice control lack multimodal verification mechanisms (such as trajectory matching and contact state coordination), resulting in a high false trigger rate. This results in long capture delays and high power consumption for existing smart glasses, making them difficult to meet the demand for instantaneous snapshots in scenarios such as cycling and sports.

[0052] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] Reference Figure 1 , a quick shooting method, comprising the following steps:

[0054] S1, obtaining environmental parameter information, wherein the environmental parameter information includes light intensity, color temperature, light frequency, infrared light intensity, and light change rate;

[0055] S2, synchronously adjusting the shooting parameters of the image sensor according to the environmental parameter information;

[0056] S3, execute shooting.

[0057] The present invention proposes an execution subject that is a smart glasses. First, the configuration table of the smart glasses is as follows:

[0058]

[0059]

[0060] Specifically, when the glasses receive a shooting command (vibration / voice / manual shutter), the main control sends a command to the ambient light sensor (ALS) to quickly start the ambient light sensor to collect external light parameters "light intensity (detecting visible light intensity to preset the ISO sensitivity of the CMOS sensor and the HDR switch), color temperature (detecting the color temperature value of the light source to preset the white balance parameters of the CMOS sensor to adjust the image color and avoid color cast), infrared light intensity (more accurate color calibration under complex light sources (such as mixed infrared / visible light), dynamic light changes (rapid changes in light intensity (such as from indoors to outdoors, sudden changes in light and dark), in sudden changes in light) When the ambient light is reduced, the night scene noise reduction mode is enabled in advance to balance image quality and noise, and the CMOS parameters are preset), the light frequency (adjusting the shutter speed according to the flicker frequency (such as 1 / 50s to match a 50Hz light source) to avoid streaks or brightness fluctuations in the picture, optimizing the exposure time through frequency data, and presetting the CMOS sensor) is sent to the main control circuit. The main control circuit sets the shooting parameters based on the parameter signal fed back by the ambient light sensor and issues control instructions to the camera. In this link, because the main control circuit quickly obtains the ambient light parameters through the ambient light sensor, it can set the camera sensor (image sensor), shortening the time the image sensor takes to collect light. The image sensor can quickly complete the photo and turn off the camera, thereby achieving fast photo shooting and reducing the power consumption of the eyewear device.

[0061] In one embodiment, before the step of obtaining environmental parameter information, the following steps are included:

[0062] Obtaining one or more of vibration information, voice information, and shutter information;

[0063] When vibration information is recognized, the preset gyroscope sensor is called to determine the trajectory information with the same timestamp;

[0064] Using the trajectory information in combination with the vibration information, confirming the shooting requirements from a preset requirements table;

[0065] generating a shooting instruction based on the shooting requirement, wherein the shooting requirement includes taking photos and recording videos;

[0066] The step of starting environmental parameter acquisition according to the shooting instruction.

[0067] During the specific implementation process, for example, when a user needs to capture road conditions while riding, they quickly lower their head 30° (triggering the gyroscope's Z-axis angular velocity to >200° / s), detecting vibration waveform characteristics with a frequency range of 8-12Hz (corresponding to riding bumps) and an acceleration amplitude of 0.5-2.5g (excluding unconscious hand shaking); matching with the preset "nod to take a photo" trajectory template (cosine similarity >0.92), triggering secondary verification: detecting changes in nose pad contact impedance for >300ms (confirming the glasses are being worn), generating a continuous shooting command (the default setting is 3 frames / 0.5 seconds), and directly calling pre-stored environmental parameters (such as ISO 800 and shutter speed 1 / 1000s). During the specific implementation process, refer to the table below:

[0068]

[0069] In another embodiment, the capacitive shutter contacts on the side of the temple (using the Cypress CY8C4024 controller) detect double-click operations (interval <500ms), synchronously detect the voice command "shoot" (short voice of 150-300ms is extracted through the endpoint detection algorithm), and verify the spatial state by confirming that the device pitch angle is within ±15° through AHRS attitude solution (excluding actions such as bending over to tie shoelaces). The heart rate sensor (such as Maxim MAX86150) automatically disables continuous shooting when it detects a heart rate greater than 100bpm. The trigger logic is: shooting is executed only when all three conditions are met at the same time; otherwise, a 15-second cooling period is entered.

[0070] In one embodiment, the step of confirming the shooting requirement includes:

[0071] Match trajectory information with the preset action library;

[0072] If the cosine similarity is greater than 0.88 and the peak acceleration is greater than 3g, a continuous shooting or video recording instruction is generated.

[0073] Specifically, when a vibration of the user's head is detected, the gyroscope sensor is immediately called to synchronously collect the motion trajectory data under the vibration timestamp, and then the acquired trajectory information is matched with the standard action template in the preset action library in real time; if the calculation result shows that the cosine similarity between the current trajectory and the preset action exceeds 0.88, and the acceleration peak is detected to be above 3g (for example, the user nods or shakes the head quickly), it is automatically determined to be a valid operation, and the corresponding shooting mode is selected from the preset instruction mapping table according to the action type - if the preset "G01" coded action (two consecutive quick nods) is matched, a three-shot continuous shooting command is triggered; if the "G03" coded action (drawing a circle with the head) is matched, a 10-second short video recording is started, thereby ensuring high-precision action recognition while achieving millisecond-level response.

[0074] In one embodiment, the step of obtaining environmental parameter information includes:

[0075] Collect light intensity and frequency through ASL ambient light sensor;

[0076] Collect color temperature through color temperature sensor;

[0077] Collect infrared light intensity through infrared sensor;

[0078] Calculates the light change rate based on the dynamic changes in light intensity.

[0079] In the specific implementation, multiple sensors work together to acquire key optical data in real time during environmental parameter collection. An ASL ambient light sensor (such as the ams TSL25911) samples ambient light intensity (0-88,000 Lux) and light frequency information (50 / 60Hz light source flicker characteristics) at 100Hz. A dedicated color temperature sensor (such as the ROHM BH1749NUC) simultaneously measures color temperatures from 1500-10000K. An infrared sensor (such as the Vishay VEML6075) independently detects infrared light intensity in the 780-1050nm band. Based on the light intensity data continuously collected by the ASL sensor, the main control chip dynamically calculates the light intensity difference (ΔLux) between adjacent time points at a fixed sampling interval of 10ms. This calculation generates a light change rate parameter (in Lux / ms) in real time using the formula (change rate = ΔLux / Δt). These four parameters are transmitted in parallel to the processing module via the SPI bus, providing input for subsequent synchronous parameter adjustments.

[0080] In one embodiment, the step of synchronously adjusting the shooting parameters of the image sensor according to the environmental parameter information includes:

[0081] At a certain moment, adjusting the ISO sensitivity and HDR switch of the CMOS sensor according to the corresponding parameter value of the light intensity;

[0082] At the same time, adjusting the white balance parameter of the CMOS sensor according to the parameter value corresponding to the color temperature, and setting the shooting color saturation based on the white balance parameter;

[0083] At the same time, the shutter speed and exposure time of the CMOS sensor are adjusted according to the corresponding parameter values ​​of the light frequency;

[0084] At the same time, the color compensation value of the CMOS sensor in a complex scene is adjusted by the corresponding parameter value of the infrared light intensity, wherein the complex scene includes a visible light scene mixed with infrared light;

[0085] At the same time, the noise reduction value of the CMOS sensor when the day scene and the night scene are transformed is adjusted by the corresponding parameter value of the light change rate, and the image quality and noise are balanced.

[0086] In the process of specific implementation,

[0087] The above hardware configuration includes:

[0088] ASL ambient light sensor (ams TSL25911): designed to detect visible light intensity in the 0-88,000 Lux range and 50 / 60 Hz light source strobe characteristics;

[0089] Color temperature sensor (model ROHM BH1749NUC): independently measures the color temperature value of 1500-10000K, through I 2 C interface communicates with the main control chip;

[0090] Infrared sensor (model Vishay VEML6075): detects infrared intensity in the 780-1050nm band and triggers sampling synchronously with the ASL sensor;

[0091] Three types of sensors are integrated into the sealed cavity at the front end of the frame (see attached Figure 4 31) in the data, ensuring data timestamp consistency through hardware synchronization signals.

[0092] processing unit,

[0093] Dedicated ISP chip: Sony IMX586 supporting DSP core

[0094] Noise reduction accelerator: Cadence TensilicaVP6 (128GOPS computing power)

[0095] The method of adjusting the ISO sensitivity of the CMOS sensor and the HDR switch by the corresponding parameter value of the light intensity is:

[0096]

[0097] The method of adjusting the white balance parameter of the CMOS sensor by the corresponding parameter value of the color temperature and setting the shooting color saturation based on the white balance parameter is:

[0098]

[0099]

[0100] The method of adjusting the shutter speed and exposure time of the CMOS sensor by the corresponding parameter value of the light frequency is:

[0101] 100Hz strobe detected

[0102] shutter_speed = 1 / 100*1.25; / / slightly faster than the light source frequency to prevent streaks

[0103] exposure_time = 8ms; / / match the flash period

[0104] When the light change rate is greater than 200 Lux / ms:

[0105] enable_rolling_shutter_comp(); / / Enable rolling shutter correction

[0106] The method of adjusting the color compensation value of the CMOS sensor in a complex scene by using the corresponding parameter value of the infrared light intensity, wherein the complex scene includes a visible light scene mixed with infrared, is as follows:

[0107]

[0108] The method of adjusting the noise reduction value of the CMOS sensor when switching between day and night scenes by using the corresponding parameter value of the light change rate and balancing the image quality and noise is as follows:

[0109] Dynamic adjustment based on light intensity gradient ΔLux / Δt

[0110]

[0111] In one embodiment, the step of adjusting the noise reduction value of the CMOS sensor when switching between daytime scenes and nighttime scenes includes:

[0112] When the light change rate exceeds the first threshold, the strong noise reduction mode is enabled and the sharpening is turned off;

[0113] When the light change rate is within the second threshold range, medium noise reduction mode is enabled and low-intensity sharpening is turned on.

[0114] In specific implementation, in shooting scenes with drastic light changes (such as entering or exiting a tunnel or the transition between day and night), the CMOS sensor noise reduction strategy is dynamically adjusted according to the real-time calculated light change rate (ΔLux / Δt): when the light change rate is detected to exceed the first threshold of 500Lux / ms (for example, the moment a vehicle exits a tunnel), the strong noise reduction mode is immediately enabled to suppress dark field noise by increasing the pixel merging density, while the sharpening processing is completely turned off to avoid noise amplification; when the light change rate is in the second threshold range of 100-500Lux / ms (such as the dusk transition stage), it switches to the medium noise reduction mode, uses a local noise suppression algorithm to preserve the detailed texture of the picture, and simultaneously turns on low-intensity sharpening (sharpening factor 0.3) to compensate for contour clarity, thereby achieving an adaptive balance between image quality and noise under complex light conditions.
