Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments and features of the embodiments of the present invention may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified.
For better understanding, the technical solutions provided by the embodiments of the present invention will be described below with reference to the drawings of the specification.
Referring to fig. 1, an embodiment of the present invention provides an incident light intensity control method, which can be executed by an incident light intensity control device, and the flow of the method is described as follows:
s101: acquiring position information of a target object;
s102: detecting the intensity of reflected light after being reflected by the target object;
s103: if the reflected light intensity is greater than a preset threshold value, determining a corresponding light-transmitting area according to the position information;
s104: the transparency of the light-transmitting area is adjusted to reduce the incident light intensity incident on the target object through the light-transmitting area.
In the embodiment of the invention, the target object can be positioned in different accommodating spaces, and light outside the accommodating spaces can be incident on the target object positioned in the accommodating spaces. The light source of the light incident into the accommodating space may be the sun or other natural light sources, or may be an artificial light source. The accommodating space may take various forms, such as a car, a room, etc. If the target object is located in a car, the incident light may be light entering the car from a window of the car, and if the target object is located in a room, the incident light may be light entering the room from a window of the room. The subject of the method may be an incident light intensity control device. The following description will take the example where the target object is located in an automobile.
The target object may include one user or a plurality of users, and the target object may include users located at any position in the automobile. Whether the target object comprises which users in the car may be preset by the incident light intensity control device, e.g. any one or more users in the car may be set as target users, or all users in the car may be set as target users. The method can also be determined by the operation of the user on the automobile, and can also be determined by the self-detection of the automobile: for example, a built-in camera of the automobile or a gravity sensor provided under each seat in the automobile may be used to detect where a user is present in the automobile, and all or part of the detected users may be determined as target users.
In one embodiment, before obtaining the location information of the target object, it may be first detected whether the target object exists in the automobile, which may be understood as detecting whether a user exists in the automobile. For example, a built-in camera of the automobile or a gravity sensor disposed under each seat in the automobile may be used to detect whether there is a user in the automobile, and if it is determined that there is no user in the automobile, the process may be ended, or all windows of the automobile may be adjusted to be opaque, so as to protect privacy in the automobile.
If the detection determines that at least one user exists in the automobile, whether the automobile is in an automatic driving state or not can be judged, and if the automobile is determined to be in the automatic driving state, all windows of the automobile can be adjusted to be opaque, so that the rest of the user in the automobile can be facilitated.
If the detection determines that at least one user exists in the automobile and determines that the automobile is not in the automatic driving state, all or part of the at least one user can be determined as the target object. Several ways of determining the target object are described below. Mode 1: if the target object is determined by presetting the incident light intensity control device, for example, if a user located at some position in the automobile is set in the incident light intensity control device to be a target object, after at least one user is determined to be in the automobile, it may be determined whether the position of the user in the at least one user is a preset position, and if the position of the user in the at least one user is a preset position, the part of the users may be determined to be the target object. Mode 2: if the target object is not preset, whether a user in the at least one user is in a sleep state or not can be judged, and if the user in the at least one user is in the sleep state, the user in the sleep state can be determined as the target object. The image of the user can be shot through a built-in camera of the automobile, whether the user is in a sleep state or not is judged according to the image of the user, or the image can be judged by acquiring data stored in wearable equipment (such as a smart watch or a smart bracelet) worn by the user. Of course, the above two ways are only examples, and the way of determining the target object in the embodiment of the present invention is not limited thereto.
After the target object is determined, position information of the target object may be obtained. The position information of a target object may include coordinate information of the target object, for example, a coordinate system may be established in the automobile, and the coordinate information of the target object may be obtained, or the position information of a target object may include seat information of the target object in the automobile. In addition, the position information of the target object may include some other possible information, such as height information of the top end of the target object with respect to the top of the car, etc., in addition to the coordinate information or the seat information of the target object.
When the incident light intensity incident on at least one target object through the vehicle window from outside the vehicle interferes with part or all of the target objects, the part of the incident light intensity is required to be controlled, so that the reflected light intensity reflected by the at least one target object is required to be detected firstly to determine whether the incident light intensity incident on the at least one target object interferes with part or all of the target objects. The reflected light intensity reflected by the target object may be detected, the reflected light intensity reflected by all regions of the target object may be detected to reduce the incident light intensity incident on all regions of the target object through the corresponding light-transmitting regions, or the reflected light intensity reflected by the eye of at least one target object may be detected to reduce the incident light intensity incident on the eye of the target object through the corresponding light-transmitting regions. The method for detecting the reflected light intensity may be various, for example, by a built-in camera of the automobile, or by a dedicated light intensity detecting device or light detecting device, such as a light sensor.
If the reflected light intensity of the target object in the reflected light intensities of the target objects after being reflected by each target object in the at least one target object is greater than a preset threshold value, or the reflected light intensity of the target object in the reflected light intensities of the target objects after being reflected by the eye parts of each target object in the at least one target object is greater than a preset threshold value, the intensity of the incident light outside the automobile is considered to possibly reach the degree of causing bad interference to the part of target objects in the automobile, a corresponding light transmission area can be determined according to the position information of the part of target objects, and the incident light intensity of the part of target objects which is incident to the part of target objects through the light transmission area is reduced by adjusting the transparency of the light transmission area. The partial target object may be referred to as a first partial target object. The preset threshold may be a light intensity value that may disturb human vision, or a light intensity value that may disturb a user who is in a sleep state.
There are various ways to determine the light-transmitting area, some of which are described below.
The first mode is as follows: the position information of the target object and the light-transmitting area can be preset with a corresponding relation, so that the corresponding light-transmitting area can be determined according to the corresponding relation after the position information of the target object is known. For example, the light-transmitting region corresponding to the driver's seat may be the entire front windshield of the automobile or a half region of the front windshield corresponding to the driver's seat, the light-transmitting region corresponding to the rear window seat may be the entire side window of the automobile closest to the seat, and so on.
The second mode is as follows: in order to more accurately determine the light-transmitting area, in addition to acquiring the position information of the target objects, the front orientation information of the first part of target objects, which is used to indicate the direction in which the front of each of the first part of target objects is oriented, may be acquired by using a built-in camera of the automobile. The light-transmitting area is obtained by detecting a built-in camera of the automobile and is a part or all area on at least one window corresponding to a part of the first part of target object face, wherein the reflected light intensity of the part is greater than a preset threshold value. For example, in a car sold in china, the light-transmitting area corresponding to the front face or eyes of the user's face on the driver's seat may be a left half area of the front windshield of the car (i.e., a half area opposite to the driver's seat), the light-transmitting area corresponding to the left face of the user on the driver's seat may be the entire left front window of the car (i.e., the side window closest to the driver's seat), and so on.
The third mode is as follows: if the light source is the sun, the corresponding light transmission area can be determined according to the position information of the first part of target objects and the incidence direction of the sunlight on the first part of target objects. The moving direction and the current time information of the first part of target objects can be acquired, and then the incident direction of sunlight incident on the first part of target objects is determined according to the moving direction and the current time information of the first part of target objects. Since the embodiment of the present invention is described with driving an automobile as a scene, the moving direction of the first part of target objects should be consistent with the advancing direction of the automobile. The direction of the vehicle can be the same as the direction of the vehicle head, and can be obtained through a Global Positioning System (GPS) or a magnetometer built in the vehicle, and the current time information is the local time of the place where the vehicle is located. After the position information of the at least one target object is acquired, a corresponding light-transmitting area may be determined according to the position information of the first part of target objects and an incident direction of sunlight incident on the first part of target objects. The light transmissive region may be an intersection of sunlight incident on the first portion of the target object with the vehicle window.
The above three ways of determining the light-transmitting area may be used separately or in combination. The manner of determining the light-transmitting region is not limited thereto.
In order to determine the light-transmitting regions more specifically, after the corresponding light-transmitting region is determined, the first region may also be determined on the light-transmitting region. The first region occupies a partial region of the light-transmitting region.
Taking any one of the first part of target objects as an example, a manner of determining the first area is introduced: and if the detection result is that the reflection light intensity of the whole area or the partial area of the target object after the transparency is adjusted is smaller than the reflection light intensity of the whole area or the partial area of the target object before the transparency is adjusted, the sub-area with the adjusted transparency belongs to the first area. The first region may comprise at least one sub-region and may be an intersection of incident sunlight incident on all or part of the region of the first portion of the target object with the vehicle window.
In the embodiment of the invention, the vehicle window can be made of a material capable of adjusting transparency, for example, a liquid crystal film made of a conductive polymer material is covered on common vehicle window glass, when alternating current is conducted, the liquid crystal structure is arranged orderly to enable the vehicle window to become transparent, light outside the vehicle can directly irradiate the vehicle, once the power supply is turned off, the liquid crystal structure becomes disordered, and the vehicle window glass becomes an opaque state to block the light outside the vehicle. Of course, the manner of adjusting the transparency of the window is not limited thereto, and the window material is not limited to the liquid crystal material.
In the embodiment of the invention, when the reflected light intensity of the target object after reflection is greater than the preset threshold value, the transparency of the light transmission area corresponding to the target object is adjusted, so that the incident light intensity of the target object through the light transmission area can be reduced, a better shading method is provided, the incident light intensity is adjusted by adjusting the transparency of the light transmission area, the adjustment result is more accurate, and the experience brought to a user is better.
