When a feature "comprises or includes" a feature or some of its coverage, this indicates that other features are not excluded and may further include other features, unless expressly stated otherwise.
In the description of the present embodiment, a description referring to the terms "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Fig. 1 is a schematic flowchart of a projection method of an in-vehicle projector according to an embodiment of the present invention, as shown in fig. 1, and in combination with fig. 2 to 9, the present invention provides the following technical solutions:
A projection method of an in-vehicle projector configured to form a projection screen on a projection carrier outside a vehicle, the projection method comprising:
s100, acquiring a visual position of an image acquirer in a vehicle and acquiring a projection picture;
s200, acquiring a vehicle body local structure of the vehicle between the projection picture and the visual position;
and S300, adjusting the seat where the vehicle-mounted projector and/or the image acquirer are positioned according to the projection picture, the visual position and the local structure of the vehicle body so that the projection picture is in the visual field of the image acquirer.
The image acquirer is a user of the vehicle-mounted projector, and the image acquirer is positioned in the vehicle to watch a projection picture of the projection carrier outside the vehicle. The projection carrier may be a curtain, screen, wall, floor, etc. Specifically, an in-vehicle projector provided on a vehicle emits a projection beam that impinges on a projection carrier outside the vehicle. The projection beam forms a projection image on the projection carrier and reflects the projection image into the vehicle for viewing by the image acquirer.
In this embodiment, the visual position may be the position of the face or the eye of the image acquirer in the vehicle, or the position of the midpoint of both eyes of the image acquirer. The vehicle body partial structure may be a door frame, a door glass, a front windshield both side a-pillar, a hood, a roof, a windshield wiper, a steering wheel, a dashboard structure, or the like. An image acquirer in a vehicle typically sits or lies on a seat, and by adjusting the seat, the position of the visual position can be adjusted.
The transparent structure, the partial structure and the opaque structure of each car body partial structure can be respectively adopted, and the projection pictures can be allowed to pass through, such as a car door glass, a front windshield, an opened car door, an opened car roof cover, a car door with the glass retracted, and the like. The door frame, front windshield both sides a-pillar, hood, roof, windshield wiper, steering wheel, instrument panel, etc. are typically opaque structures that block the projected image when between the visual position and the projected image. In addition, the glass structure with variable transparency can be regarded as a transparent structure when the glass structure is in a state of high transparency, and does not obstruct the projection screen. When the transparent structure is in a state of low transparency, the transparent structure can be regarded as an opaque structure, and the projection picture can be blocked.
The field of view of an image acquirer in a vehicle is a perceptible visual range, and when a part of the projection screen is blocked by an opaque body part structure, the part of the projection screen is outside the field of view.
In this embodiment, the information of the visual position of the image acquirer may be acquired by means of an in-vehicle camera, a radar, a seat sensor, a wearable device of the image acquirer, reading preset data, and the like. The information of the local structure of the vehicle body between the projection picture and the visual position can be obtained through the modes of a camera in the vehicle, a radar, reading preset data and the like. The information of the projection picture can be obtained through the modes of a camera, a radar, the state of a vehicle-mounted projector, reading preset data and the like. By the relative position and size of the projection picture, the body part structure and the visual position, it can be judged whether the complete projection picture can penetrate from the body part structure into eyes of an image acquirer in the vehicle, that is, whether the projection picture is blocked by an opaque structure in the body part structure, so that the image acquirer cannot watch the complete projection picture.
In general, in-vehicle projectors have a function of adjusting the size of a projection screen, and some in-vehicle projectors also have a function of adjusting the angle of the projection screen, that is, changing the orientation of a projection lens of the in-vehicle projector, and changing the position of the center of the projection screen on a projection carrier.
In this embodiment, when it is determined that a portion of the projection screen is blocked by an opaque structure in the vehicle body partial structure, the state of the vehicle-mounted projector may be changed, for example, the area of the projection screen may be reduced, and for example, the position of the center of the projection screen may be moved up and down, so that the complete projection screen may enter the visual position of the image acquirer in the vehicle. Therefore, the image acquirer can watch the complete projection picture, and the effect of improving the watching experience of the image acquirer is achieved.
In this embodiment, when it is determined that a portion of the projection screen is blocked by an opaque structure in the vehicle body partial structure, the visual position of the image acquirer may be changed, for example, the position of the image acquirer in the vehicle may be changed, the current posture of the image acquirer may be changed from a sitting posture to a lying posture, or the like, and the position of the eyes of the image acquirer may be changed, so that the complete projection screen may enter the visual position of the image acquirer in the vehicle. Therefore, the image acquirer can watch the complete projection picture, and the effect of improving the watching experience of the image acquirer is achieved.
It is to be understood that two adjustment modes of changing the state of the vehicle-mounted projector and changing the visual position of the image acquirer can be implemented independently or jointly and mutually matched, so that the image acquirer can watch a complete projection picture, and the effect of further improving the watching experience of the image acquirer is achieved.
It should be noted that the projection screen or the projection screen may be actually presented, that is, the vehicle-mounted projector is in an operating state, and projects onto the actual projection screen of the projection carrier. The projection picture or the projection picture can also be virtual, i.e. the vehicle-mounted projector does not actually project the light beam, but the projection picture is calculated by the optical principle according to the geometric relation between the state of the vehicle-mounted projector and the relative angle and the relative position of the projection carrier.
In some embodiments of the projection method of the present invention, as shown in fig. 2, the adjusting the vehicle-mounted projector according to the projection screen, the visual position and the local structure of the vehicle body so that the projection screen is within the field of view of the image acquirer includes:
s311, obtaining a visual field range according to the visual position and the local structure of the vehicle body;
s312, obtaining a plurality of vertexes of the boundary of the projection picture;
s313, judging whether all vertexes are in the visual field range;
And S314, if not, adjusting the state of the vehicle-mounted projector to change the positions of at least part of the vertexes so as to enable all the vertexes to be in the visual field range.
The field of view of an image acquirer in a vehicle is a perceptible visual range, and when a part of the projection screen is blocked by an opaque body part structure, the part of the projection screen is outside the field of view.
The projection screen of the in-vehicle projector is generally in a regular shape, such as a rectangular surface, a trapezoidal surface, or the like. Correspondingly, the boundary of the projection picture is usually an edge formed by sequentially connecting a plurality of straight lines and a plurality of vertexes. In general, a complete projected picture can be considered to be viewable by an in-vehicle image acquirer when all sides and vertices of the projected picture are in the field of view of the in-vehicle image acquirer.
On the other hand, the partial structure of the vehicle is usually a regular shape, such as an a-pillar on both sides of the front windshield, and when the projected screen is blocked, some sides and some vertices of the boundary of the projected screen are blocked at the same time, and only some sides of the boundary of the projected screen are not blocked.
Therefore, in the present embodiment, only the vertices of the boundary of the projection screen can be monitored and judged. When all vertices are in the field of view of the in-vehicle image acquirer, the complete projected image is considered to be viewable by the in-vehicle image acquirer. When part of the vertexes are out of the view range of the image acquirer in the vehicle, the state of the vehicle-mounted projector needs to be adjusted to change the position, the size, the shape and the like of the projection picture, so that all the vertexes are in the view range of the image acquirer in the vehicle.
In other embodiments of the projection method of the present invention, the position of the vertices of the projection screen in the field of view of the in-vehicle image acquirer may also be changed by adjusting the visual position of the in-vehicle image acquirer so that all vertices are in the field of view of the in-vehicle image acquirer.
In some embodiments of the projection method of the present invention, as shown in fig. 3, the adjusting the seat where the image acquirer is located according to the projection screen, the visual position and the local structure of the vehicle body so that the projection screen is within the field of view of the image acquirer includes:
s321, acquiring seat information of a seat where an image acquirer is located;
s322, adjusting the seat according to the projection picture, the car body local structure, the visual position and the seat information so as to change the visual position, and further enabling the projection picture to be in the visual field range.
The visual position may be the position of the face or eyes of the image acquirer in the vehicle, or the position of the midpoint of both eyes of the image acquirer. The visual position depends on the pose of the image acquirer within the vehicle. Typically, an image acquirer in a vehicle sits or lies in a seat while viewing the projection. The seat information may include the position of the seat in which the image acquirer is located in the vehicle, such as the first left-hand seat, and may be obtained by associated sensors of the seat, as well as by cameras in the vehicle, wearable equipment of the image acquirer, and the like.
The seat information may also include the posture of the seat in which the image acquirer is located in the vehicle, such as the height of the seat, the position of the seat in the front-rear direction of the vehicle, the angle of the backrest of the seat, the orientation of the seat, the angle of the seat with respect to the horizontal plane, and the like. This information may be obtained by a sensor associated with the seat, or by a camera in the vehicle, radar, wearable equipment of the image acquirer, etc.
The seat information may also include the sitting position of the image acquirer in the vehicle on the seat, such as sitting straight, sitting reclined, lying sitting, etc. This information may be obtained by a sensor associated with the seat, or by a camera in the vehicle, radar, wearable equipment of the image acquirer, etc.
By acquiring the seat information of the seat in which the image acquirer is located in the vehicle, the visual position of the image acquirer can be determined, for example, the position of the eyes of the image acquirer. Compared with the method that the visual position of an image acquirer in a vehicle is directly acquired through a camera, a radar and the like in the vehicle, the method of the seat information is quicker and is not interfered by the outside. For example, when the visual position of an image acquirer in a vehicle is acquired by means of a camera in the vehicle, a better lighting condition is required, and it is obviously not easy to apply to outdoor night viewing projection.
On the other hand, by acquiring the seat information, when it is judged that the projection screen is blocked by the opaque vehicle body partial structure, the posture of the seat can be correspondingly adjusted, for example, the height of the seat is increased, the seat is moved forward, the direction of the seat is rotated, and the like, so that the complete projection screen can be viewed by an image acquirer in the vehicle.
In some embodiments of the projection method of the present invention, as shown in fig. 4, the capturing the visual position of the image acquirer in the vehicle includes:
s111, acquiring the height of an image acquirer;
s112, acquiring seat information of a seat where an image acquirer is located;
s113, obtaining the visual position of the image acquirer according to the height and the seat information of the image acquirer.
On the one hand, in the same seat and sitting position, different heights can affect the position of the eyes. By acquiring the height of the image acquirer, the position of the eyes of the image acquirer in the vehicle can be more accurately judged in combination with the seat information.
On the other hand, it is common that the image acquirer of one vehicle is a limited number, such as the vehicle owner, the family of the vehicle owner, and the like. By acquiring or presetting the height of the image acquirer of the vehicle and combining the seat information of the seat in which the image acquirer is positioned, the position of eyes of the image acquirer in the vehicle can be rapidly and accurately judged.
In some embodiments of the projection method of the present invention, as shown in fig. 5, after the adjusting the vehicle-mounted projector and the seat where the image acquirer is located so that the projection screen is within the field of view of the image acquirer, the projection method further includes:
s411, storing the state of the vehicle projector;
S412, storing the visual position;
s413, after the next acquisition of the visual position, adjusting the in-vehicle projector based on the stored visual position and the stored state of the in-vehicle projector.
In this embodiment, the state of the in-vehicle projector includes the projection angle and the size of the projection screen. When the current projection picture is completely watched by an image acquirer in a vehicle, the state and the visual position of the current vehicle-mounted projector can be stored as a first preset state, so that when the vehicle-mounted projector is used next time, the visual position is consistent with the first preset state, and the projection carrier is positioned at the same position, the state of the vehicle-mounted projector is automatically adjusted to be the state in the first preset state, the operation of manually adjusting the vehicle-mounted projector by the image acquirer is omitted, or the occupied time of automatically adjusting the vehicle-mounted projector is saved, and the use experience of the image acquirer is improved.
It is to be understood that the first preset state may comprise a plurality of preset states, for example, a plurality of first preset states may be set for the relative distance between the projection carrier and the vehicle, and each relative distance corresponds to one of the first preset states.
In some embodiments of the projection method of the present invention, as shown in fig. 6, after adjusting the visual positions of the vehicle projector and the seat where the image acquirer are located so that the projection screen is within the field of view of the image acquirer, the projection method further includes:
S511, storing the state of the vehicle-mounted projector;
s512, storing the height of the image acquirer;
s513 of storing seat information;
s514, after the next acquisition of the height of the image acquirer, adjusting the in-vehicle projector and adjusting the seat based on the stored height of the image acquirer, the stored seat information, and the stored state of the in-vehicle projector.
In this embodiment, when the current projection screen is completely watched by the image acquirer in the vehicle, the state of the current vehicle-mounted projector, the current seat information and the height of the current image acquirer are stored as the second preset state, when the same image acquirer or the image acquirer with the same height uses the vehicle-mounted projector next time, and the projection carrier is at the same position, the seat is automatically adjusted to be in the posture in the second preset state, and the vehicle-mounted projector is automatically adjusted to be in the state in the second preset state, so that the operation of manually adjusting the seat and the vehicle-mounted projector by the image acquirer is avoided, and the use experience of the image acquirer is improved.
It should be appreciated that the second preset state may include a plurality of preset states, for example, a plurality of second preset states may be set for different image acquirers or image acquirers of different heights, and each relative distance corresponds to one second preset state.
In this embodiment, when the vehicle-mounted projector is used by the image acquirer in the vehicle, the state of the vehicle-mounted projector can be automatically adjusted according to the height of the image acquirer, the seat information, the relative position between the projection carrier and the vehicle-mounted projector, and the like, and the posture of the seat can be adjusted, so that the experience of the image acquirer is improved.
It should be noted that, the vehicle-mounted projector may preset a second preset state corresponding to the height of the image acquirer, the seat information, the relative position of the projection carrier and the vehicle-mounted projector, and the like when leaving the factory, and when the height of the image acquirer, the seat information, the relative position of the projection carrier and the vehicle-mounted projector, and the like match with preset conditions, the state of the vehicle-mounted projector may be automatically adjusted to be the first preset state, and the posture of the seat is adjusted to be the second preset state, so that the image acquirer realizes that the image acquirer obtains the optimal posture of watching projection without sense, and the use experience is improved.
As shown in table 1, table 1 is a comparison table of height-seat posture preset according to a certain vehicle model. Wherein the attitude of the seat includes the height of the seat and the angle of the backrest of the seat. For example, when the height of the image acquirer is 154.7 cm, the corresponding second preset state is: the height of the seat is adjusted to be the highest, and the backrest of the seat is adjusted to be the back 25 degrees, so that the hood is prevented from shielding a projection picture on the front projection carrier, and an image acquirer can have a comfortable posture.
TABLE 1
In some embodiments of the projection method of the present invention, as shown in fig. 7, the in-vehicle projector 10 is disposed inside the head of the vehicle, and the projection carriers 30 are disposed at intervals in front of the vehicle.
