Description

Technical Field

[0001] The present invention relates to the field of imaging technology, and more specifically, to a disordered pendulum time perception imaging system and device. Background Art

[0002] With the development of science and technology, many fields such as scientific research, aerospace, military applications, precision manufacturing, etc. have increasingly higher requirements for the accuracy of time measurement. Traditional clocks and timers may not be able to meet the needs in extreme environments or when there are extremely high requirements for accuracy. Therefore, it is necessary to develop new time perception technologies.

[0003] Existing imaging systems mostly use digital clocks or electronic clocks to record time information. Although these methods can meet basic time recording needs, in some special scenarios, such as extremely low temperatures, strong electromagnetic interference and other environments, the accuracy of traditional clocks will be affected, resulting in inaccurate recorded time. Summary of the invention

[0004] In order to overcome the problem of inaccurate time recording caused by the prior art in environments such as extremely low temperature and strong electromagnetic interference, the present invention designs a disordered pendulum time perception imaging system and device that can effectively solve the above technical problems.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0006] A disordered pendulum time perception imaging system, a disordered pendulum time perception element unit, an image sensor unit, a data processing unit, an image display unit, a calibration unit, a storage unit and a user interface;

[0012] The storage unit is used to store original image data, processed image data and time information to facilitate subsequent data analysis and playback.

[0013] The user interface allows the user to set the time display format, adjust the projection area and image effects.

[0014] Preferably, the disordered pendulum achieves precise swinging through an electromagnetic driver, which includes an electromagnetic coil and a magnet. The start, stop and swing amplitude of the disordered pendulum are adjusted by adjusting the magnitude and direction of the current. The motion trajectory of the disordered pendulum is monitored in real time by a laser ranging sensor, and the period of the disordered pendulum is calculated, thereby achieving high-precision time perception.

[0015] Preferably, the novel photoelectric sensor comprises at least one light emitting diode and a photodetector, wherein the light emitting diode emits light to the reflective mark on the disordered pendulum, and the photodetector receives the reflected light, thereby monitoring the swinging position and speed of the disordered pendulum.

[0016] Preferably, the data processing unit comprises the following steps:

[0017] Collecting the signal output by the photoelectric sensor, filtering and amplifying the signal to remove noise;

[0018] Calculating the swing period of the disordered pendulum by a digital signal processing algorithm;

[0019] Convert the swing period into specific time information;

[0020] Synchronize time information with image data.

[0021] Preferably, the step of calculating the swing period of the disordered pendulum by a digital signal processing algorithm further comprises:

[0022] The analog signal output by the photodetector is sampled using a high sampling rate analog-to-digital converter;

[0023] Perform preliminary preprocessing on the sampled digital signal;

[0026] Statistical analysis is performed on multiple swing cycles, and standard deviation is calculated to evaluate the stability of the swing cycle.

[0027] The step of converting the swing period into specific time information further includes:

[0028] Identify a known time reference;

[0029] Using a time reference signal to time-calibrate the swing period;

[0030] Calculate the number of seconds corresponding to each swing based on the swing period;

[0044] A disordered pendulum time perception imaging device is implemented by the disordered pendulum time perception imaging system described above.

[0045] Compared with the prior art, the beneficial effects of the present invention are as follows: the disordered pendulum time perception imaging system and device proposed by the present invention, compared with the existing imaging system that records time information by means of digital clocks or electronic clocks, shows significant advantages under special environments. First, the system adopts a disordered pendulum as a time perception element, combines an electromagnetic driver and a laser ranging sensor to achieve precise swing and real-time monitoring, and effectively avoids the influence of extremely low temperature, strong electromagnetic interference and other environments on the accuracy of time recording. Because the swing period of the disordered pendulum is determined by physical principles and is relatively independent of the external environment, as long as the electromagnetic driver and the sensor can work normally, the accuracy of the time information can be ensured. Secondly, the system uses a high-performance microprocessor to process the photoelectric sensor signal, extract the time information, and display the time information in real time in a designated area through projection technology. This process not only realizes the visualization of time information, but also ensures the synchronization of time information and image data, providing users with a more intuitive and accurate time reference. In addition, the system also has a calibration unit that can automatically adjust the electromagnetic driver parameters to maintain the accuracy of time information. This function enables the system to self-repair and calibrate in the face of external environmental changes or equipment aging factors to ensure long-term stable operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In order to more clearly illustrate the implementation methods of the present invention or the technical solutions in the prior art, the drawings required for use in the implementation methods or the description of the prior art will be briefly introduced below. Obviously, the drawings in the following description are only exemplary, and for ordinary technicians in this field, other implementation drawings can be derived based on the provided drawings without paying any creative work.

[0047] Figure 1 This is a structural diagram of a disordered pendulum time perception imaging system. DETAILED DESCRIPTION

[0048] The drawings are for illustrative purposes only and should not be construed as limiting the present patent;

[0049] In order to better illustrate the present embodiment, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0050] It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0051] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0052] Example

[0053] A disordered pendulum time perception imaging system, such as Figure 1As shown, a disordered pendulum time sensing element unit, an image sensor unit, a data processing unit, an image display unit, a calibration unit, a storage unit and a user interface;

[0054] The disordered pendulum time sensing element unit comprises a plurality of disordered pendulums and a laser distance measuring sensor, wherein the plurality of disordered pendulums are all made of magnetic materials, and the plurality of disordered pendulums achieve precise swinging through an electromagnetic driver;

[0055] The multiple disordered pendulums represent hours, minutes, seconds, milliseconds, etc. respectively, and the multiple disordered pendulums use multiple disordered pendulums with different frequencies and amplitudes, and realize the movement of the pendulums through magnetic field driving.

[0056] With the improvement of time resolution, disordered pendulums of different frequencies can represent different time units. For example, a low-frequency disordered pendulum can represent hours, a medium-frequency disordered pendulum can represent minutes, and a high-frequency disordered pendulum can represent seconds. In this way, the swing period of each disordered pendulum corresponds to a time unit, which can improve the resolution of time measurement.

[0057] Avoid synchronization errors. If all random pendulums swing at the same frequency and amplitude, they may become synchronized due to some external factors (such as vibration or electromagnetic interference), resulting in measurement errors. Using random pendulums with different frequencies and amplitudes can reduce the risk of such synchronization errors.

[0058] The image sensor unit adopts a photoelectric sensor to achieve real-time monitoring of disordered pendulum swing;

[0059] External photoelectric effect type sensors, photoconductive effect type sensors and photovoltaic effect type sensors can be used.

[0060] The data processing unit uses a high-performance microprocessor to process the photoelectric sensor signal and extract time information;

[0061] The image display unit uses projection technology to project time information to a designated area;

[0062] The calibration unit automatically adjusts the electromagnetic drive by comparing the built-in reference clock with the swing cycle of the disordered pendulum to maintain the accuracy of the time information;

[0063] The storage unit is used to store original image data, processed image data and time information to facilitate subsequent data analysis and playback.

[0064] The user interface allows the user to set the time display format, adjust the projection area and image effects.

[0065] The disordered pendulum achieves precise swinging through an electromagnetic driver, which includes an electromagnetic coil and a magnet. By adjusting the magnitude and direction of the current, the disordered pendulum can be started, stopped, and the swing amplitude can be adjusted. The motion trajectory of the disordered pendulum is monitored in real time using a laser ranging sensor, and the cycle of the disordered pendulum is calculated, thereby achieving high-precision time perception.

[0066] The specific method is: when it is necessary to start the disorder pendulum, the direction of the current in the electromagnetic coil must be determined first. The direction of the current will determine the direction of the force exerted on the magnet (usually connected to the disorder pendulum or as part of the disorder pendulum). By changing the direction of the current, it can be ensured that the magnet is subjected to a force opposite to the static position of the disorder pendulum, thereby causing it to start swinging.

[0067] The magnitude of the current determines the strength of the force exerted on the magnet. In order to start the disordered pendulum, it is necessary to choose a current value that is large enough to ensure that the magnet obtains sufficient initial kinetic energy.

[0068] Too much current may cause the disordered pendulum to start too quickly or swing too much, while too little current may not enable the disordered pendulum to overcome static friction and start. Therefore, the current size needs to be carefully adjusted to find the optimal starting conditions.

[0069] When it is necessary to stop the disordered pendulum, this can be achieved by reversing the direction of the current in the electromagnetic coil, which will cause the force on the magnet to be in the direction opposite to the direction of the pendulum's movement, thus slowing it down and eventually stopping it.

[0070] In order to stop the disordered pendulum smoothly, the current in the electromagnetic coil can be gradually reduced. This will gradually reduce the resistance to the magnet, thereby avoiding the shock or vibration caused by the sudden stop of the disordered pendulum.

[0071] The swing amplitude is related to the force exerted on the magnet (i.e. the current in the electromagnetic coil) and the initial position of the disordered pendulum. By adjusting the current, the force exerted on the magnet can be changed, thereby affecting the swing amplitude of the disordered pendulum. Increasing the current will increase the force exerted on the magnet, allowing the disordered pendulum to obtain a larger swing amplitude; reducing the current will reduce the swing amplitude.

[0072] The novel photoelectric sensor includes at least one light emitting diode and a photodetector. The light emitting diode emits light to the reflective mark on the disordered pendulum, and the photodetector receives the reflected light, thereby monitoring the swinging position and speed of the disordered pendulum.

[0073] The data processing unit comprises the following steps:

[0074] Collecting the signal output by the photoelectric sensor, filtering and amplifying the signal to remove noise;

[0075] Calculating the swing period of the disordered pendulum by a digital signal processing algorithm;

[0076] Convert the swing period into specific time information;

[0077] Synchronize time information with image data.

[0078] The step of calculating the swing period of the disordered pendulum by a digital signal processing algorithm further comprises:

[0079] The analog signal output by the photodetector is sampled using a high sampling rate analog-to-digital converter (ADC);

[0080] Perform preliminary preprocessing on the sampled digital signal;

[0081] It includes DC offset correction and signal amplitude normalization, applying a digital low-pass filter to remove high-frequency noise and retain the main frequency components related to the disordered pendulum swing, and using a digital high-pass filter to eliminate low-frequency drift to ensure that the signal reflects the actual swing of the disordered pendulum.

[0082] Using an edge detection algorithm (such as the Canny algorithm) to determine the swing peak in the signal, that is, the extreme point of the disordered pendulum swing;

[0083] Calculate the time interval between two consecutive extreme points, which is a swing cycle;

[0084] In order to improve the accuracy, multiple swing periods can be averaged to obtain a more stable swing period value.

[0085] Statistical analysis is performed on multiple swing cycles, and standard deviation is calculated to evaluate the stability of the swing cycle. If the cycle stability exceeds a preset threshold, a calibration procedure is started through the calibration unit to adjust the electromagnetic drive parameters.

[0086] The step of converting the swing period into specific time information further includes:

[0087] Determine a known time reference; for example, a pulse per second signal (1PPS);

[0088] Using a time reference signal to time-calibrate the swing period;

[0089] Calculate the number of seconds corresponding to each swing according to the swing period. For example, if each swing of the disordered pendulum represents 1 second, then directly convert the number of swings into seconds;

[0090] By accumulating the number of swings, the current hour, minute and second are calculated.

[0091] Format the calculated time data into a standard time format, such as HH:MM:SS;

[0092] Provides time adjustment capabilities to cope with daylight saving time changes or time zone adjustments.

[0093] The synchronizing of time information with image data further comprises:

[0094] Embed a timestamp in the metadata of each image frame to record the acquisition time of the image frame, ensuring that the accuracy of the timestamp matches the image frame rate;

[0095] In the image processing unit, extracting the timestamp information and converting it into a visual grid;

[0096] Use image overlay technology to overlay time information onto image data, ensuring that time information is displayed synchronously with image content;

[0097] Verify the accuracy of time synchronization by comparing the actual displayed time information with the expected time;

[0098] If time deviation is found, adjust the timestamp or image playback rate to ensure time synchronization.

[0099] The image display unit includes the following technical steps:

[0100] receiving processed image data and time information;

[0101] Projecting image data onto a screen or wall through a projector;

[0102] Overlay time information on the projected image. The time information is displayed as a transparent layer. Adjust the focus and brightness of the projector to ensure that the time information is clearly visible.

[0103] A disordered pendulum time perception imaging device is implemented by the disordered pendulum time perception imaging system described above.

[0104] In a specific implementation, a plurality of disordered pendulums are manufactured, each of which is made of a magnetic material and fixed on an independent bracket. An electromagnetic driver is provided for each disordered pendulum, which is composed of an electromagnetic coil and a magnet. The start, stop and swing amplitude of the disordered pendulum are controlled by adjusting the magnitude and direction of the current. A laser ranging sensor is installed to monitor the motion trajectory of each disordered pendulum in real time, and high-precision time perception is achieved by calculating the trajectory period. The laser ranging sensor is installed on each side of the disordered pendulum bracket, so that the movement of the disordered pendulum in two directions can be monitored simultaneously. If space permits, the laser ranging sensor can be installed vertically above or below the swing plane of the disordered pendulum, and the position of the disordered pendulum is monitored by emitting a laser downward or upward and receiving a reflected signal. The laser ranging sensor can also be installed at the extreme position (i.e., the end point) of the swing of the disordered pendulum, so that the maximum swing amplitude of the disordered pendulum can be accurately measured.

[0105] Select high-performance photoelectric sensors, including at least one light-emitting diode and one photodetector. The at least one light-emitting diode and one photodetector mentioned here must ensure the measurement of the position and speed of the disordered pendulum. When there are multiple sensors, if one of the sensors fails, the other sensors can still work normally, thus ensuring the continuous and stable operation of the system. This design improves the overall reliability and fault tolerance of the system. Multiple sensors can also provide more data points. By comparing and analyzing these data, the system can more accurately monitor the movement of the disordered pendulum. This method can reduce the errors that may be introduced by a single sensor, thereby improving the accuracy of time perception.

[0106] A light-emitting diode is placed on the swing path of each disordered pendulum to emit light to the reflective mark on the disordered pendulum. A photodetector receives the reflected light to monitor the swing position and speed of the disordered pendulum.

[0107] A high-performance microprocessor is used to collect the signal output by the photoelectric sensor, and filter and amplify it to remove noise. A high-sampling-rate analog-to-digital converter is used to sample the analog signal of the photoelectric detector and perform preprocessing.

[0108] The edge detection algorithm is used to determine the swing peak in the signal, and the time interval between two consecutive extreme points is calculated to determine the swing period.

[0109] Statistical analysis is performed on multiple swing cycles, the standard deviation is calculated to evaluate the stability of the swing cycle, and the electromagnetic drive parameters are adjusted by the calibration unit if necessary.

[0110] Use projection technology to project the processed image data onto a screen or wall.

[0111] Time information is superimposed on the projected image and displayed as a transparent layer.

[0112] Adjust the focus and brightness of the projector to ensure that the time information is clearly visible.

[0113] By comparing the swing period of the disordered pendulum with the built-in reference clock, the electromagnetic drive is automatically adjusted to maintain the accuracy of the time information.

[0114] Design a storage unit to store raw image data, processed image data, and time information, and develop a user interface that allows users to set the time display format, adjust the projection area, and image effects.

[0115] The same or similar reference numerals correspond to the same or similar components;

[0116] The terms used in the drawings to describe positional relationships are only used for illustrative purposes and should not be construed as limiting this patent;

[0117] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here.
