For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. Based on the embodiments of the present application, every other embodiment obtained by a person skilled in the art without making any inventive effort falls within the scope of protection of the present application.
With the development of intelligent technology of automobiles, the cost of Head up display devices (HUDs for short) is reduced, and more automobiles are equipped with HUDs. The HUD can display prompt information such as speed, rotating speed, navigation, fault warning and the like in the front head-up range of the driver, and is combined with surrounding real scenes, so that the frequency of a low-head observation instrument of the driver is reduced to improve driving safety, and meanwhile, the perception of the driver to surrounding environment is improved.
In order to enable drivers to watch complete HUD images, the projection positions of the HUD images need to be adjusted, when the HUD images are adjusted, proper HUD height settings of each driver are stored (face information corresponds to the HUD height settings), and the corresponding stored data are automatically matched in a face recognition mode when the HUD images are used next time, so that the HUD heights are automatically adjusted. However, the HUD height adjustment in the prior art is manually adjusted, and each user/driver needs to be manually adjusted at least once. In the adjustment process, after the driver is required to operate (generally, the HUD height adjustment is required to enter a corresponding setting item on the central control screen), the driver returns to the driving sitting position to confirm whether the virtual image position is adjusted in place, the driver can be required to go back and forth for several times normally, and the process is relatively complicated.
Based on the above, the embodiment of the application provides a HUD image position adjusting method, so as to realize automatic adjustment of the HUD image position and reduce manual operation.
Referring to fig. 1, fig. 1 is a flowchart of a HUD image position adjusting method according to an embodiment of the present application. As shown in fig. 1, an adjusting method provided by an embodiment of the present application includes:
s101, acquiring a face image of a target driver acquired by an image acquisition device.
Here, the image capturing device may be a camera installed on the target vehicle, and the camera may be a DMS camera, or may be another camera, such as an OMS, or another camera installed in the vehicle and capable of capturing a human face.
The camera can be an RGB monocular camera (comprising color, black and white, infrared and the like), an RGBD depth camera, the depth camera has binocular, TOF, grating and other types, and can also be an in-cabin radar capable of outputting 3D information.
Wherein, the face image of the target driver acquired by the image acquisition device can be acquired at specified time intervals by the acquisition instruction. It should be noted that the specified time interval can be set in advance according to the requirement, for example, the specified time interval can be 1 hour, 3 hours, 6 hours, or the like. The acquisition instruction can be triggered when the driver acts on a virtual switch or a hardware switch of the automobile through a specified operation, which can be a click operation, a slide operation, a toggle operation, a push operation, a voice operation, or the like.
For example, referring to fig. 2, fig. 2 is a schematic diagram of an internal structure of an automobile with a HUD according to the present application. As shown in fig. 2, after the face image of the target driver is collected by the image collecting device, the collected face image may be transmitted to the HU cabin host by the controller. As shown in fig. 2, a possible application scenario provided by the present application is provided. The application scenario is exemplified with the HUD system applied to a vehicle. The HUD system is used for projecting instrument information (vehicle speed, temperature, oil quantity and the like) and navigation information and the like on a vehicle into the visual field of a driver through a windshield of the vehicle, wherein a virtual image corresponding to the navigation information can be superimposed on a real environment outside the vehicle, so that the driver can obtain an augmented reality visual effect, and the HUD system can be used for AR navigation, self-adaptive cruising, lane departure early warning and the like. Since the virtual image corresponding to the navigation information needs to be combined with the real image, the vehicle is required to have accurate positioning and detection functions, and generally the HUD system needs to be matched with an advanced driving assistance system (advanceddriving assistant system, ADAS) system of the vehicle. It should be noted that the above scenario is only an example, and the HUD system provided by the present application may be applied to other scenarios, for example, may also be applied to an aircraft (such as a fighter plane), and the fighter plane may perform object tracking and aiming based on the HUD system, thereby helping to improve the success rate and flexibility of combat.
The following explains some terms in fig. 2 in the present application. It should be noted that these explanations are for the convenience of those skilled in the art, and do not limit the scope of the present application.
Eye box: an eye box generally refers to the area where the driver's eyes can see the entire displayed image, see fig. 1 above. To accommodate differences in the height of the driver, the typical eye box size is 130mm by 50mm, i.e., the driver's eyes have a range of movement of about + -50 mm in the longitudinal direction and about + -130 mm in the lateral direction. If the driver's eyes are within the range of the eye box, a complete and clear image can be seen. If the driver's eyes are out of the range of the eye box, distortion of the image, color error, etc. may be seen, and even the image cannot be seen.
PGU: in one possible implementation, the PGU includes a display screen that is separable into a plurality of regions, such as a first region for emitting a first light and a second region for emitting a second light.
Primary mirror: alternatively, the primary mirror may be a first planar mirror; alternatively, the primary mirror is a first curved mirror.
In one possible implementation, a primary mirror nearest the PGU is configured to receive the first light from the PGU and reflect the first light toward a secondary mirror. Therefore, the first reflecting mirror can be used for folding the light path of the first light ray once.
A secondary mirror: alternatively, the secondary mirror may be a curved mirror.
In one possible implementation, a secondary mirror nearest to the primary mirror is configured to receive the first light from the secondary mirror after the optical path is folded and reflect the first light after the optical path is folded toward the windshield.
In one possible implementation, the secondary mirror further comprises a rotation axis for adjusting the position of the virtual image on the windscreen.
Before acquiring a face image of a target driver, the target driver is detected to determine whether the target driver meets an adjustment triggering condition. For example, the adjustment triggering condition may be detecting that the target driver has belted the seat belt, or detecting that the target driver starts the automobile, or the adjustment triggering condition may be other, which is not limited herein.
S102, recognizing the facial image, and determining a first relative position of eyes of the target driver and the image acquisition device.
Here, a position determination algorithm may be predetermined, by which the eyes of the target driver in the face image are detected, and the first relative position of the eyes of the target driver and the image pickup device is determined based on the detected human eye information.
S103, determining a third relative position between the eyes of the target driver and the windshield based on the first relative position and a predetermined second relative position between the image acquisition device and the windshield.
Here, the second relative position between the image pickup device and the windshield is determined based on the in-vehicle device design position information. The second relative position between the image acquisition device and the windshield is specifically the relative position between the image acquisition device and the HUD light reflection area in the windshield.
Wherein the third relative position includes: the relative distance and angle of the target driver's eyes to the HUD light reflecting area in the windshield.
Thus, the determining a third relative position between the target driver's eyes and the windshield includes: a third relative position of the target driver's eyes and a HUD light reflecting area in the windshield is determined.
Wherein, HUD light reflection area is the required position of HUD projection virtual image in the windshield.
S104, determining a fourth relative position of the HUD projection image and the eye box area of the target driver based on a third relative position between the eyes of the target driver and the windshield.
Here, the fourth relative position includes: horizontal position and vertical distance.
The eye box area is an area range of eye movement of a target driver, and the eye box area is a rectangular area and is positioned at the center of an eyeball. Within the field of the eye-box, the eye can see the entire image projected by the HUD.
It should be noted that there is a fixed area/range on the front windshield for reflecting HUD light, i.e., HUD light reflecting area; when the vehicle is designed, a standard eye position (which can be understood as a standard height) is set at the driver position; when the HUD is designed, the standard eye box position is designed according to the standard eye position, so that the adjustable range of the eye box is designed for adapting to different heights; the so-called virtual image adjustment is to adjust the eye box to the actual eye position, and the driver experiences that the position of the virtual image (generally, the height of the virtual image) is adjusted (actually, the angle of a curved mirror is adjusted to change the incident angle of HUD light to a windshield, the incident angle is changed synchronously, the height of reflected light is changed, and the reverse height of the virtual image is also changed); wherein. The size of the eye box is generally 130x50mm (horizontal x vertical), the eyes are in the middle area of the eye box, and the adjustable range of the eye box is generally +/-50 mm. Thus, a fourth relative position may be determined based on the third relative position.
With continued reference to fig. 2, the HUD projection image required by the driver is an image that the light emitted by the PGU (image generating unit) is projected by the primary mirror, the secondary mirror and reflected by the front windshield of the automobile and then finally transmitted to the eye position (the eye box area) corresponding to the height of the driver, i.e. the driver can see the complete virtual image.
And S105, adjusting the position of the HUD projection image based on the fourth relative position so as to enable the target driver to acquire all projection images.
In one embodiment of the present application, adjusting the position of the HUD projection image based on the fourth relative position includes: determining a target refraction angle of the curved mirror according to the fourth relative position; and adjusting the curved mirror according to the target refraction angle so as to adjust the position of the HUD projection image.
In another embodiment of the present application, the adjusting the curved mirror according to the target refraction angle includes: and determining a target rotation angle of the curved mirror based on the target refraction angle, and adjusting the curved mirror according to the target rotation angle.
It should be noted that, when the HUD optical path is designed, virtual images at different positions are known to have corresponding angle data of the curved mirror, and when the curved mirror is adjusted according to the target rotation angle, the virtual images can be controlled by a stepping motor.
With continued reference to fig. 2, the secondary mirror in fig. 2 is a curved mirror, which is a free-form mirror. The HUD optical path adjustment principle in this scheme will be described with reference to fig. 2: the HUD internal module PGU emits light, the light is reflected by the first-stage reflecting lens and then by the second-stage reflecting lens/curved mirror (motor control, angle can be changed), the light is emitted to the front windshield, the light enters the eyes of a driver after being reflected by the front windshield, and a virtual image is seen after the light is converged.
When the HUD is designed and the light rays are known to be incident on the front windshield at different angles, virtual images at different positions can be seen in the range of the eye box area. The HUD incidence angle is obtained by changing the angle of the curved mirror (the incident light of the curved mirror is fixed, the angle of the curved mirror is changed actually, the angle of the curved mirror is changed synchronously, the direction of the light reflected by the curved mirror is changed), namely, different virtual image positions are obtained by adjusting the corresponding angle of the curved mirror, and the corresponding angle of the curved mirror can be obtained by controlling the motor in the HUD.
In addition, after the adjustment of the virtual image position required by the target driver is completed, an adjustment parameter is acquired, and a face image of the driver, a HUD parameter adjusted by the driver and a parameter value are stored correspondingly. Thus, when the target driver uses the vehicle next time, the target vehicle can acquire the identity information of the driver of the target vehicle, determine the HUD parameters and the parameter values matched with the identity information of the driver, automatically adjust the HUD parameters of the vehicle according to the HUD parameters and the corresponding parameter values, and further, under the condition that multiple people use the target vehicle, the HUD parameters of the target vehicle do not need to be frequently adjusted by the driver, so that the experience of the driver is improved.
The embodiment of the application provides a method and a system for adjusting the position of a HUD image, wherein the method for adjusting the position of the HUD image comprises the following steps: acquiring a face image of a target driver acquired by an image acquisition device; identifying the facial image and determining a first relative position of the eyes of the target driver and the image acquisition device; determining a third relative position between the target driver's eye and the windshield based on the first relative position and a predetermined second relative position between the image capture device and the windshield; determining a fourth relative position of the HUD projected image and the target driver's eye-box area based on a third relative position between the target driver's eyes and the windshield; and adjusting the position of the HUD projection image based on the fourth relative position so as to enable the target driver to acquire all projection images.
Therefore, through the technical scheme provided by the application, the automatic adjustment of the HUD image position can be realized, and the manual operation is reduced, so that the HUD image position adjustment is simpler and more convenient.
