[0043] Figure 1 This is a block diagram illustrating a vehicle according to an embodiment of the present disclosure.

[0044] Reference Figure 1According to one embodiment of this disclosure, vehicle 1000 may include a first headlight 100 and a second headlight 200. For example, the first headlight 100 may be the left headlight of vehicle 1000, and the second headlight 200 may be the right headlight of vehicle 1000. As another example, the first headlight 100 may be the right headlight of vehicle 1000, and the second headlight 200 may be the left headlight of vehicle 1000.

[0045] The first vehicle light 100 may include a first sensor 110, a first display 120, and a first controller 130. According to one embodiment, the first vehicle light 100 may further include a first driver 140.

[0046] The first sensor 110 can sense the distance (first distance) of an object in front of the vehicle 1000. For example, the object may include a wall in front of the vehicle 1000. Alternatively, the first sensor 110 may include a distance sensor or a camera.

[0047] The first display 120 can display images. For example, the first display 120 can be controlled by the first controller 130.

[0048] The first controller 130 can compensate for image distortion based on a distance (first distance) sensed by the first sensor 110. For example, the first controller 130 can compensate for image distortion by correcting the image based on the first distance.

[0049] The first driver 140 can rotate the first headlight 100. For example, the first driver 140 can be controlled by the first controller 130.

[0050] The second vehicle light 200 may include a second sensor 210, a second display 220, and a second controller 230. According to one embodiment, the second vehicle light 200 may also include a second driver 240.

[0051] The second sensor 210 can sense the distance (second distance) of an object in front of the vehicle 1000. For example, the object may include a wall in front of the vehicle 1000. Alternatively, the second sensor 210 may include a distance sensor or a camera.

[0052] The second display 220 can display images. For example, the second display 220 can be controlled by the second controller 230.

[0053] The second controller 230 can compensate for image distortion based on a distance (second distance) sensed by the second sensor 210. For example, the second controller 230 can compensate for image distortion by correcting the image based on the second distance.

[0054] The second driver 240 can rotate the second headlight 200. For example, the second driver 240 can be controlled by the second controller 230.

[0055] According to one embodiment, the first vehicle light 100 can communicate with the second vehicle light 200. For example, the first controller 130 and the second controller 230 can compare a first distance and a second distance. In this case, based on the first distance and the second distance, only one of the first vehicle light 100 and the second vehicle light 200 can display an image. For example, when the first distance is less than or equal to the second distance, the first vehicle light 100 can display an image. As another example, when the first distance exceeds the second distance, the second vehicle light 200 can display an image.

[0056] According to one embodiment, the vehicle 1000 may further include sensors external to the first headlight 100 and the second headlight 200. For example, the external sensors may include ADAS sensors such as LiDAR. As another example, the external sensors can sense the 360-degree omnidirectional orientation of the vehicle 1000. According to one embodiment, the external sensors can sense the tilt of the projection surface, the tilt relative to a wall, and the tilt of the front and rear sides of the vehicle body. For example, the external sensors can measure the distances to the left and right sides of the wall, respectively, and transmit the corresponding information to other devices inside the vehicle 1000 (e.g., the first headlight 100 or the second headlight 200), which can then calculate the angles of tilt relative to the left and right walls.

[0057] Figure 2 This is a view showing a vehicle projection image according to an embodiment of the present disclosure;

[0058] refer to Figure 2 The first headlight 100 or the second headlight 200 of vehicle 1000 can project an image onto the object 10 in front of vehicle 1000. Although Figure 2 The illustration shows the first headlight 100 projecting an image onto the object 10, but this disclosure is not limited thereto. For example, the vehicle 1000 may project an image simultaneously using the first headlight 100 and the second headlight 200, or it may project an image using only the second headlight 200.

[0059] The first headlight 100 and the second headlight 200 can communicate with each other and can determine one of the first headlight 100 and the second headlight 200 to project an image. For example, the vehicle 1000 can determine the headlight that is closer to the object 10, either the first headlight 100 or the second headlight 200, to project an image.

[0060] According to one embodiment, when the distance between the first vehicle headlight 100 and the object 10 is equal to the distance between the second vehicle headlight 200 and the object 10, the vehicle 1000 can determine the projected image of the first vehicle headlight 100. However, this disclosure is not limited thereto. For example, the vehicle 1000 can determine the projected image of the second vehicle headlight 200, or determine that the first vehicle headlight 100 and the second vehicle headlight 200 project images simultaneously. According to one embodiment, a controller (e.g., included in the first vehicle headlight 100 and the second vehicle headlight 200) is used. Figure 1 The first controller 130 and the second controller 230 can communicate with each other to determine the projected image of the vehicle lights.

[0061] Figure 3 and Figure 4 This is a view showing the calculation of the angle formed between the vehicle and an object according to an embodiment of the present disclosure.

[0062] refer to Figure 3 and Figure 4 The first headlight 100 included in the vehicle 1000 can sense the distance "d1" between itself and the object 20. In addition, the second headlight 200 included in the vehicle 1000 can sense the distance "d2" between itself and the object 20.

[0063] Including the controller in the first vehicle light 100 (e.g., Figure 1 The first controller 130) and the controller included in the second vehicle light 200 (e.g., Figure 1 The second controller 230) can communicate with each other to obtain a first distance "d1" and a second distance "d2". Furthermore, the controller included in the first vehicle light 100 (e.g., Figure 1 The first controller 130) and the controller included in the second vehicle light 200 (e.g., Figure 1 The second controller 230 can calculate the angle “θ” formed between the object 20 and the vehicle 1000.

[0064] exist Figure 3 Since the second distance "d2" is greater than the first distance "d1", the first vehicle light 100 or the second vehicle light 200 can obtain the value "d2-d1" by subtracting the first distance "d1" from the second distance "d2". Furthermore, the angle "θ" formed between the vehicle 1000 and the object 20 can be calculated using trigonometric functions based on the distance between the first vehicle light 100 and the second vehicle light 200. In this case, since the value "d2-d1" is positive, the angle "θ" is also positive.

[0065] exist Figure 4In this process, the value "d2-d1" can be obtained by subtracting the first distance "d1" from the second distance "d2", and the angle "θ" formed between the vehicle 1000 and the object 30 can be calculated using trigonometric functions based on the distance between the first light 100 and the second light 200. In this case, since the value "d2-d1" is negative, the angle "θ" represents a negative value.

[0066] Figure 5 This is a block diagram illustrating a vehicle headlight according to an embodiment of the present disclosure.

[0067] Reference Figure 5 According to one embodiment of this disclosure, the vehicle light 300 may include a sensor 310, a display 320, and a controller 330. According to one embodiment, the vehicle light 300 may further include a driver 340. According to one embodiment, the vehicle light 300 can be connected to… Figure 1 The first headlight 100 or the second headlight 200 are substantially the same. In other words, the sensor 310 can be substantially the same as the first sensor 110 or the second sensor 210, and the display 320 can be substantially the same as the first display 120 or the second display 220. In addition, the controller 330 can be substantially the same as the first controller 130 or the second controller 230, and the driver 340 can be substantially the same as the first driver 140 or the second driver 240.

[0068] Sensor 310 can sense the distance to objects in front of the vehicle. For example, the object may include a wall surface. Alternatively, sensor 310 may include a distance sensor or a camera. For example, the distance sensor may include at least one of the following: a light detection and ranging (LIDAR) sensor, a radar sensor, an infrared (IR) sensor, or a time-of-flight (ToF) sensor. Sensor 310 can transmit the sensed distance information to controller 330.

[0069] Display 320 can display images. For example, display 320 may include high-resolution LEDs. For example, display 320 may be controlled by controller 330. As another example, the image may include an image processed by controller 330.

[0070] The controller 330 can compensate for distortion of the image displayed on the object based on the distance sensed by the sensor 310. For example, the controller 330 can compensate for image distortion by correcting the image.

[0071] The controller 330 can calculate the angle between the vehicle and the object based on the distance to the object. For example, the controller 330 can calculate the angle between the vehicle and the object through methods such as... Figure 3or Figure 4 The method shown calculates the angle between the vehicle and the object.

[0072] The controller 330 can correct the image based on a calculated angle. For example, the controller 330 can correct the image to a trapezoidal shape based on the angle. According to one embodiment, the controller 330 can correct the image based on the angle so that the image is displayed on the object in a rectangular shape.

[0073] Figure 6 This is a view showing a headlight correction image according to an embodiment of the present disclosure. Figure 6 The headlight 300 shown can be connected with Figure 5 The headlights are basically the same as those of the 300.

[0074] Reference Figure 6 The headlight 300 can calculate the angle "θ" formed between the vehicle and the object 40 based on the distance "d" between the vehicle and the object 40. For example, the controller 330 included in the headlight 300 can calculate the angle "θ" formed between the vehicle and the object 40.

[0075] The controller 330 can calculate the region 50 for displaying the image based on the angle "θ" formed between the vehicle and the object 40. For example, the region 50 for displaying the image can be calculated using the function "H(θ)" based on the angle "θ" formed between the vehicle and the object 40.

[0076] The controller 330 can correct the image based on the shape of the region 50 where the image is displayed. For example, the controller 330 can correct the image to have the same shape as the region 50 where the image is displayed. As another example, when the image is displayed on region 50, the controller 330 can correct the image to display it as a rectangle. Yet another example, the controller 330 can correct the image to a trapezoidal shape based on an angle "θ" or a function "H(θ)".

[0077] According to one embodiment, the controller 330 can display a corrected image on the object 40 via the display 320, and can display the image without distortion.

[0078] Also refer to Figure 5 According to one embodiment of this disclosure, the vehicle light 300 may further include a driver 340. For example, the driver 340 may rotate the display 320.

[0079] The controller 330 can control the driver 340. For example, the controller 330 can control the driver 340 to cause the display 320 to project an image onto the object perpendicularly.

[0080] The controller 330 can pre-obtain the rotation radius of the driver 340. The controller 330 can compare the rotation radius of the driver 340 with the angle formed between the vehicle and the object. For example, when the angle between the vehicle and the object is less than or equal to the rotation radius of the driver 340, the controller 330 can control the driver 340 so that the display 320 projects an image perpendicular to the object. Alternatively, when the angle between the vehicle and the object exceeds the rotation radius of the driver 340, the controller 330 can correct the image based on that angle and control the display 320 to output the corrected image.

[0081] According to one embodiment, the driver 340 can rotate the display 320 outward from the vehicle. For example, when the driver 340 rotates the display 320 inward from the vehicle, the driver 340 may collide with another device inside the vehicle. Therefore, the driver 340 can rotate the display 320 outward from the vehicle. In other words, when the driver 340 needs to rotate the display 320 inward from the vehicle so that the display 320 projects an image perpendicular to the object, the controller 330 can perform control operations to correct the image and output the image through the display 320, without the driver 340 controlling it.

[0082] Figure 7 This is a view showing a headlight correction image according to an embodiment of the present disclosure. Figure 7 The headlight 300 shown can be connected with Figure 5 The headlights shown are basically the same as those of the 300 model.

[0083] refer to Figure 7 According to one embodiment of the present disclosure, the controller 330 included in the vehicle headlight 300 can calculate the angle formed between the vehicle and the object 60, and can control the driver 340 based on the calculated angle "θ" so that the display 320 projects an image perpendicular to the object 60 onto the object 60.

[0084] According to one embodiment, the driver 340 can rotate the display 320 outward from the vehicle (in... Figure 7 (In the direction shown). For example, when the driver 340 needs to rotate the display 320 into the vehicle so that the display 320 projects an image onto the object perpendicularly, the controller 330 can perform the control operation of correcting the image and outputting the image through the display 320 without the driver 340 controlling it.

[0085] According to one embodiment of this disclosure, the vehicle headlight 300 can compensate for distortion of the image displayed on the object based on the distance to the object.

[0086] According to one embodiment of this disclosure, the vehicle headlight 300 can compensate for the distortion of the image displayed on an object by correcting the image.

[0087] According to one embodiment of this disclosure, the vehicle headlight 300 can compensate for the distortion of the image displayed on the object by adjusting the projection angle of the image.

[0088] According to one embodiment of this disclosure, the vehicle headlight 300 can compensate for the distortion of an image displayed on an object by determining whether to correct the image or rotate the headlight based on the rotation radius of the headlight.

[0089] Figure 8 This is a flowchart illustrating a method for operating vehicle lights according to an embodiment of the present disclosure; Figure 8 The operation shown can be performed by Figure 5 The vehicle lights are 300.

[0090] refer to Figure 8 According to one embodiment of the present disclosure, a method for operating a vehicle headlight 300 may include: sensing the distance to an object in front of the vehicle (S110), compensating for distortion of an image displayed on the object based on the distance to the object (S120), and displaying the image (S130).

[0091] In the step of sensing the distance to an object in front of the vehicle (S110), sensor 310 can sense the distance to the object in front of the vehicle. For example, sensor 310 may include at least one of the following: a LiDAR sensor, a radar sensor, an IR sensor, or a ToF sensor.

[0092] In the process of compensating for image distortion displayed on an object based on distance to the object (S120), the controller 330 can compensate for the distortion of the image displayed on the object based on the distance to the object. For example, the controller 330 can compensate for the distortion of the image displayed on the object by correcting the image based on the distance to the object. Alternatively, the controller 330 can compensate for the distortion of the image displayed on the object by controlling the driver 340 to rotate the display 320 based on the distance to the object.

[0093] In the image display (S130), the display 320 can display an image. For example, the display 320 can display a corrected image via the controller 330. Alternatively, when the driver 340 rotates the display 320, the display 320 can output an image without correction. According to one embodiment, when the image is corrected via the controller 330, or when the display 320 projects an image perpendicularly onto the object via the driver 340, the display 320 can display an undistorted image on the object.

[0094] Figure 9 This is a flowchart illustrating a method for operating vehicle lights according to an embodiment of the present disclosure.

[0095] refer to Figure 9According to one embodiment of this disclosure, a method for operating a vehicle headlight 300 may include calculating an angle formed between the vehicle and the object based on the distance to the object (S210), comparing the angle with the rotation radius of a driver (S220), correcting an image based on the angle (S230), and performing a control operation such that the image is projected onto the object perpendicularly to the object (S240). According to one embodiment, S210 to S240 may include... Figure 8 The S120.

[0096] In the calculation of the angle between the vehicle and the object based on the distance to the object (S210), the controller 330 can calculate the angle between the vehicle and the object based on the distance to the object. For example, the controller 330 can... Figure 3 or Figure 4 The method shown calculates the angle between the vehicle and the object.

[0097] In comparing the angle with the rotation radius of the driver (S220), the controller 330 can compare the calculated angle with the rotation radius of the driver 340. For example, the controller 330 can obtain the rotation radius of the driver in advance. Or, for example, the controller 330 can execute S230 or S240 based on the comparison result between the calculated angle and the rotation radius of the driver 340.

[0098] When the calculated angle exceeds the rotation radius of the driver 340, in the angle-based image correction (S230), the controller 330 can correct the image based on the calculated angle. For example, the controller 330 can correct the image to a trapezoidal shape based on the angle. According to one embodiment, the controller 330 can correct the image based on the angle such that the image is displayed on the object in a rectangular shape.

[0099] When the calculated angle is equal to or less than the rotation radius of the driver 340, in the execution of the control operation that projects the image onto the object perpendicularly (S240), the controller 330 can control the driver 340 to project the image onto the object perpendicularly. For example, the driver 340 can rotate the display 320 so that the display 320 projects the image onto the object perpendicularly.

[0100] According to one embodiment of this disclosure, in a method of operating the vehicle headlights 300, the radius of rotation of the driver 340 can be compared with the angle between the vehicle and the object. The comparison result can be used to correct the image or to determine whether the display 320 has been rotated.

[0102] According to one embodiment of this disclosure, in a vehicle headlight and a method of operating it, image distortion displayed on an object can be compensated by correcting the image.

[0103] According to one embodiment of this disclosure, in a vehicle headlight and a method of operating it, distortion of an image displayed on an object can be compensated by adjusting the projection angle of the image.

[0104] According to one embodiment of this disclosure, in a vehicle headlight and a method of operating it, by determining whether to correct the image or rotate the headlight based on the rotation radius of the headlight, distortion of the image displayed on the object can be compensated.

[0105] In addition, various effects can be provided directly or indirectly through this disclosure.
