The embodiment of the invention provides a sunshade control method, which is applicable to the sunshade in the above embodiment, and the driving mechanism 3 of the sunshade is connected with the sunshade controller 7, for example, when the sunshade is applied to an automobile, the sunshade controller 7 can be a car body controller or a microprocessor. As shown in fig. 6, the sun visor control method includes:

S601: acquiring current induction data;

s602: determining a target length corresponding to the sun shield according to the current induction data;

s603: the sunshade assembly 4 is controlled to extend or wind up from the strip opening according to the target length.

The current sensing data is data sensed at the current moment, and specifically, the data sensed at the current moment is used for evaluating whether the sunshading board needs to be controlled to work.

As an example, in step S601, the sunshade controller 7 is connected to the information collecting module 6, so as to obtain the current sensing data collected by the information collecting module 6 in real time. Generally, the information acquisition module 6 is arranged on a corresponding device/structure on which the sun visor is mounted, and the current sensing data acquired by the information acquisition module is data for evaluating whether the sun visor needs to be controlled to work.

The target length is the length of the sunshade assembly 4 extending from the strip-shaped opening 5 to be controlled. When the sun visor is adapted to be used in a car, the target length corresponding to the sun visor can be understood as a designated position to which it is necessary to control the extension of the sun visor assembly 4 of the sun visor.

As an example, in step S602, after the current sensing data is obtained, the sunshade controller 7 may call a preset sunshade control logic, and perform analysis and calculation on the current sensing data by using the sunshade control logic to determine a target length corresponding to the sunshade. The sunshade control logic is preset, and the current sensing data is used as input to calculate the extension length of the sunshade.

As an example, in step S603, the sunshade controller 7 is connected to the driving mechanism 3 of the sunshade, and after determining the target length corresponding to the sunshade, the sunshade controller 7 may control the driving mechanism 3 to operate, so that the driving mechanism 3 controls the sunshade assembly 4 to extend or wind from the strip-shaped opening 5 to the target length, so as to achieve sunshade or non-sunshade.

In this embodiment, whether there is a sunshade demand may be evaluated according to the current sensing data, and a target length corresponding to the sunshade may be determined according to the evaluation result; when sunshade is required, the driving mechanism 3 controls the sunshade assembly 4 to extend out of the strip-shaped opening 5 so as to realize sunshade; when there is no sunshade demand, the driving mechanism 3 controls the sunshade assembly 4 to be rolled up from the strip-shaped opening 5, so that sunshade is not realized, the driving mechanism 3 can conveniently control the extension length of the automobile sunshade, and the maximization of the visual field is ensured while sunshade is ensured.

In one embodiment, the current sensed data includes current illumination intensity and current video data;

step S602, namely, determining a target length corresponding to the sun visor according to the current sensing data, includes:

s6021: according to the current video data, acquiring eye position information and sun irradiation angle;

s6022: acquiring actual illumination intensity according to the eye position information, the sun illumination angle and the current illumination intensity;

S6023: if the actual illumination intensity is larger than the preset illumination intensity, determining the target length corresponding to the sun shield according to the eye position information and the sun illumination angle;

s6024: if the actual illumination intensity is not greater than the preset illumination intensity, determining the default length as the target length corresponding to the sun shield.

The current illumination intensity refers to illumination intensity acquired at the current moment. As an example, the current illumination intensity may be the illumination intensity acquired in real time by the illumination intensity sensor 61.

The current video data refers to video data collected at the current moment. As an example, the current video data may be video data acquired by the image acquisition device 62 (e.g., a camera) in real time, where the video data includes an eye environment image corresponding to at least one frame of the target object. For example, when the sun visor is suitable for an automobile, the target object is a driver and a person, and the current video data is video data of the driver and the person collected in real time by a camera arranged on the automobile, wherein the video data comprises a plurality of frames of eye environment images corresponding to the driver and the person. The eye environment image herein refers to a captured image including an eye region and its surrounding region.

As an example, in step S6021, after the current sensing data is acquired, the sunshade controller 7 may first select a plurality of frames of eye environment images from the image acquisition device 62 (such as a camera), input the eye environment images into a preset image analysis model, and determine the eye position information and the sun irradiation angle according to the output result of the image analysis model. The image analysis model here is a pre-trained analysis model, and may be, for example, a model determined by training a training sample using a neural network model.

As an example, in step S6022, the sunshade controller 7 may call a predetermined illumination intensity calculation formula, calculate several input parameters including the eye position information, the sun illumination angle and the current illumination intensity, obtain a calculation result corresponding to the illumination intensity calculation formula, and determine the calculation result as the actual illumination intensity. The illumination intensity calculation formula is a preset formula for calculating the actual illumination intensity, and mainly uses eye position information and sun illumination angle to calculate an adjustment coefficient, and then determines the corresponding actual illumination intensity according to the current illumination intensity and the adjustment coefficient (for example, the product of the current illumination intensity and the adjustment coefficient). Understandably, according to the eye position information and the sun irradiation angle, the current illumination intensity is adjusted, and the actual illumination intensity is determined as the illumination intensity of the eye region, and is the illumination intensity irradiated to the eyes of the target object.

The preset illumination intensity is preset for evaluating whether the larger standard is reached or not.

As an example, in step S6023, after calculating the actual illumination intensity, the sun-shading controller 7 compares the actual illumination intensity with the preset illumination intensity, and if the actual illumination intensity is greater than the preset illumination intensity, it is determined that the actual illumination intensity reaches a larger standard, the incident sunlight will affect the target object, at this time, a preset length calculation formula may be called to calculate two input parameters, that is, the eye position information and the sun illumination angle of the target object, and determine the target length of the sun-shading board.

For example, when the sun visor is suitable for an automobile, the sun visor is arranged at the top of the automobile, and when sun shading operation is required, sunlight irradiates an intersection of solar rays corresponding to the lowest position of the eyes of a target object and the front windshield of the automobile according to the eye position information and the sun irradiation angle of the target object, and the intersection is determined as a target irradiation point; and then determining the target length of the sun shield according to the distance between the strip-shaped opening 5 of the sun shield and the target irradiation point so as to control the sun shield to carry out sun shield operation.

The default length may be a preset length, for example, when the shielding operation is not required, the default length may be set to 0, or may be set to another length that does not affect the field of view.

As an example, in step S6024, after calculating the actual illumination intensity, the sun-shading controller 7 compares the actual illumination intensity with the preset illumination intensity, and if the actual illumination intensity is not greater than the preset illumination intensity, it is determined that the actual illumination intensity does not reach the larger standard, and the incident sunlight does not affect the target object, and at this time, the default length may be determined as the target length of the sun-shading board. For example, when the actual illumination intensity is not greater than the preset illumination intensity, the default length 0 may be set as the target length of the sun-shading board, so as to ensure the subsequent automatic control, and the sun-shading component 4 thereof is fully rolled up; alternatively, the current length may be determined as the target length of the sunshade, without controlling the sunshade assembly 4, simplifying the control logic.

In this embodiment, according to the current video data, several parameters including eye position information, sun irradiation angle and current illumination intensity are obtained, the sunshade controller 7 is utilized to calculate actual illumination intensity, determine whether the actual illumination intensity is greater than a preset illumination intensity, evaluate whether incident sunlight will affect a target object, and determine a target length corresponding to the sunshade according to an evaluation result; when the actual illumination intensity is larger than the preset illumination intensity and the incident sunlight can affect the target object, the sun-shading controller 7 calculates and determines the target length of the sun-shading board; when the actual illumination intensity is not greater than the preset illumination intensity, the default length is determined as the target length of the sun shield when the incident sunlight does not affect the target object, so that the target length of the sun shield can be rapidly determined, and the sun shield is conveniently controlled by the driving mechanism 3 to carry out sun shield operation.

In one embodiment, step S603, i.e. controlling the sunshade assembly 4 to extend or wind up from the strip opening 5 according to the target length, includes:

s6031: monitoring the current length corresponding to the sun shield;

s6032: if the current length is smaller than the target length, the sunshade assembly 4 is controlled to extend from the strip-shaped opening 5 to the target length;

S6033: and if the current length is not smaller than the target length, controlling the sunshade assembly 4 to be rolled up from the strip-shaped opening 5 to the target length.

The current length is the length of the sun shield at the current moment, and specifically, the length of the sun shield 4 extending from the strip-shaped opening 5.

As an example, in step S6031, the sunshade controller 7 may select a plurality of frames of the sunshade environmental image from the image collecting device 62 (such as a camera), input the sunshade environmental image into a preset image analysis model, and call a length calculation formula according to an output result of the image analysis model to determine the length of the present time of the sunshade. The length calculation formula is a preset formula for calculating the actual extension length of the sun visor.

As an example, in step S6032, after calculating the current length of the sun-shading board, the sun-shading controller 7 compares the current length with the target length, if the current length is smaller than the target length, it is determined that the sun-shading board does not reach the designated position and cannot meet the sun-shading requirement, and at this time, the driving mechanism 3 controls the sun-shading component 4 to extend from the strip-shaped opening 5 to the designated position, so that the current length of the extending sun-shading component 4 is equal to the target length, thereby meeting the sun-shading requirement.

For example, when the sun shield is suitable for an automobile, the sun shield is arranged at the top of the automobile, and when sun shield operation is required, the current length corresponding to the sun shield is monitored, and the target length is not reached; the driving mechanism 3 controls the sunshade assembly 4 to extend from the strip-shaped opening 5 to a specified position, so that the current extending length of the sunshade assembly 4 is equal to the target length, thereby meeting the sunshade requirement.

As an example, in step S6033, after calculating the current length of the sun-shading board, the sun-shading controller 7 compares the current length with the target length, if the current length is not less than the target length, the sun-shading board is determined to reach or exceed the specified position, so as to meet the sun-shading requirement, but when exceeding the specified position, the sun-shading board can shade the line of sight, at this time, the driving mechanism 3 controls the sun-shading component 4 to wind up from the strip-shaped opening 5 to the specified position, so that the current length of the sun-shading component 4 is equal to the target length, and the phenomenon that the line of sight is blocked while meeting the sun-shading requirement is achieved.

For example, when the sun shield is suitable for an automobile, the sun shield is arranged at the top of the automobile, when the sun shield operation is needed, the current length corresponding to the sun shield is monitored, and when the current length exceeds the target length, the phenomenon of shielding the sight line can occur; the driving mechanism 3 controls the sunshade component 4 to be rolled up from the strip-shaped opening 5 to a designated position, so that the current length of the sunshade component 4 is equal to the target length, thereby meeting the sunshade requirement, avoiding the phenomenon of shielding the sight and ensuring the maximum visual field.

In this example, the sun-shading effect can be evaluated according to the current length corresponding to the monitored sun-shading plate, and the sun-shading plate adjustment requirement is determined according to the evaluation result; when the sunshade requirement cannot be met, the driving mechanism 3 controls the sunshade assembly 4 to extend from the strip-shaped opening 5 to a specified position, so that the current extending length of the sunshade assembly 4 is equal to the target length, and the sunshade requirement is met; when the phenomenon of shielding the sight appears, the driving mechanism 3 controls the sunshade component 4 to be rolled up to the appointed position from the strip-shaped opening 5, so that the current length of the sunshade component 4 is equal to the target length, thereby meeting the sunshade requirement, avoiding the phenomenon of shielding the sight and ensuring the maximum visual field. The setting is convenient for adjust and control the actual extension length of sunshading board in a flexible way according to actual conditions, guarantees effective sunshade and guarantees the maximum field of vision simultaneously.

In one example, the current sensed data includes current light intensity and current video data, and the visor control method includes:

s701: according to the current video data, acquiring eye position information and sun irradiation angle;

s702: acquiring actual illumination intensity according to the eye position information, the sun illumination angle and the current illumination intensity;

S703: judging whether the actual illumination intensity exceeds the preset illumination intensity or not;

s704: calculating the corresponding target length of the sun shield;

s705: controlling the sunshade assembly 4 to extend out of the strip-shaped opening 5 to a target length to a specified position;

s706: judging whether the current sunshade assembly 4 extends out or not;

s707: the sunshade assembly 4 is recovered for concealment.

As an example, in step S701, after the current sensing data is acquired, the sunshade controller 7 may first select a plurality of frames of eye environment images from the image acquisition device 62 (such as a camera), input the eye environment images into a preset image analysis model, and determine the eye position information and the sun irradiation angle according to the output result of the image analysis model.

As an example, in step S702, after obtaining the eye position information, the sun irradiation angle, and the current illumination intensity, the sun-shading controller 7 calculates the several input parameters, obtains a calculation result corresponding to the illumination intensity calculation formula, and determines the calculation result as the actual illumination intensity.

As an example, in step S703, the sunshade controller 7 determines whether the actual illumination intensity exceeds the preset illumination intensity.

When the actual illumination intensity exceeds the preset illumination intensity, it is determined that the actual illumination intensity reaches a larger standard, and the incident sunlight affects the target object, step S704 is executed: and calculating the corresponding target length of the sun shield. The sunshade controller 7 may invoke a preset length calculation formula, calculate two input parameters, namely, eye position information and sun irradiation angle of a target object, determine a target length of a sunshade, select a plurality of frames of environmental images of the sunshade from the image acquisition device 62 (such as a camera), input the environmental images of the sunshade into a preset image analysis model, invoke a length calculation formula according to an output result of the image analysis model, and determine a length of the sunshade at a current moment.

As an example, in step S704, the sunshade controller 7 may evaluate the sunshade effect according to the current length of the monitored sunshade, determine the sunshade adjustment requirement according to the evaluation result, and execute S705: controlling the sunshade assembly 4 to extend out of the strip-shaped opening 5 to a target length to a specified position; when the sunshade requirement cannot be met, the driving mechanism 3 controls the sunshade assembly 4 to extend from the strip-shaped opening 5 to a specified position, so that the current extending length of the sunshade assembly 4 is equal to the target length, and the sunshade requirement is met; when the phenomenon of shielding the sight appears, the driving mechanism 3 controls the sunshade component 4 to be rolled up to the appointed position from the strip-shaped opening 5, so that the current length of the sunshade component 4 is equal to the target length, thereby meeting the sunshade requirement, avoiding the phenomenon of shielding the sight and ensuring the maximum visual field. The setting is convenient for adjust and control the actual extension length of sunshading board in a flexible way according to actual conditions, guarantees effective sunshade and guarantees the maximum field of vision simultaneously.

When the actual illumination intensity is not greater than the preset illumination intensity, it is determined that the actual illumination intensity does not reach the larger standard, and the incident sunlight does not affect the target object, and step S706 is executed: judging whether the current sunshade assembly 4 is extended.

As an example, in step S706, the sunshade controller 7 determines the target length of the sunshade plate by using the default length, the sunshade controller 7 first selects a plurality of frames of environmental images of the sunshade plate from the image acquisition device 62 (such as a camera), inputs the environmental images of the sunshade plate into a preset image analysis model, and invokes a length calculation formula according to the output result of the image analysis model to determine the current state of the sunshade assembly 4 at the current moment. When the sunshade component 4 is not extended, the sunshade component 4 is completely rolled up to ensure the subsequent automatic control; when the sunshade assembly 4 is extended, step S707 is performed: the sunshade assembly 4 is recovered and hidden, and the sunshade controller 7 controls the driving mechanism 3 to control the sunshade assembly 4 to be rolled up from the strip-shaped opening 5 to be fully retracted, or the current length can be determined as the target length of the sunshade, so that the sunshade assembly 4 is not required to be controlled, and the control logic is simplified.

In this embodiment, the sunshade controller 7 evaluates whether the sunshade is required to be opened or retracted according to the current sensing data, and when the sunshade is required to be opened for sunshade, the driving mechanism 3 can be controlled to work, so that the sunshade component 4 connected with the driving mechanism extends out of the strip-shaped opening 5, and the sunshade effect is realized; when the sun shield is not required to be opened for sun shading, the driving mechanism 3 can be controlled to work, so that the sun shield assembly 4 connected with the driving mechanism is wound up from the strip-shaped opening 5, and the sun shield is not realized.

If the actual illumination intensity is larger than the preset illumination intensity, calculating the length of the sunshade component 4 to extend according to the eye position information and the sun illumination angle, and controlling the sunshade component 4 to extend from the strip-shaped opening 5; has been opened, no control is required; not opened, and needs to be controlled; if the actual illumination intensity is not greater than the preset illumination intensity, controlling the sunshade assembly 4 to be wound from the strip-shaped opening 5, and controlling the sunshade assembly to be opened; not opened, and no control is required.
