Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart of a vehicle lamp control method according to an embodiment of the present disclosure. As shown in fig. 1, the method may include the following steps.
In step 11, in the case where the vehicle headlamp is turned on, first information indicating eye data of the driver and second information indicating an eye tracking mode are determined.
Because different drivers have differences in height, driving postures and driving seat states, the spatial positions of the eyes of the drivers are different in the driving process, so that the visual range of the drivers is different, and the visual range of the drivers is influenced by the difference of the visual line directions of the drivers.
The first information may include eye position information and gaze angle information of the driver. The eye position information may indicate a position of an eye of a driver during driving, where the position is a spatial position of a space in the vehicle, that is, a position of the eye of the driver relative to the vehicle body. This position may be determined by the position sensor alone, or the position may be determined in combination with the data of the position sensor and the image sensor. For example, a three-dimensional coordinate system may be established with a certain position in the vehicle (e.g., a center of a steering wheel, a front window of the vehicle, a console of the vehicle, etc.) as an origin, and the eye position information of the driver may be determined by determining coordinates of the eyes of the driver in the three-dimensional coordinate system. For another example, the eye position information corresponding to the position of the driver's eye in the in-vehicle space may be calibrated in advance through a plurality of tests, the vehicle may store the calibration information, and the eye position information may be determined according to the detected position of the driver's eye when the driver drives the vehicle and the headlight is turned on.
The gaze angle information may reflect the direction in which the driver's eyes are focused, which may be obtained by analyzing (e.g., image analysis) the driver's eyes. Illustratively, the gaze angle information may be, for example, up, down, left, right. For another example, a standard line-of-sight angle at which the driver looks straight ahead may be determined, and a deviation (e.g., a deviation direction and a deviation angle) of the line of sight of the driver from the standard line-of-sight angle may be used as the line-of-sight angle information.
In one possible implementation, as shown in fig. 2, the determining of the first information in step 11 may include the following steps.
In step 21, the eye position information of the driver is collected by the position collecting device.
For example, a position acquisition device, such as a position sensor, may be provided on the vehicle. The position of the eyes of the driver detected by the position acquisition device can directly determine the eye position information of the driver. For example, since the position of the position acquisition device is fixed, the positions of the respective positions of the vehicle interior space relative to the position acquisition device may be calibrated in advance to obtain the position calibration result, and after the position of the eyes of the driver relative to the position acquisition device is obtained, the position of the eyes of the driver may be determined according to the calibration result, so as to obtain the eye position information of the driver.
In step 22, the eye image information of the driver is acquired.
An image capture device (e.g., a camera) may be provided on the vehicle to capture image information of the driver. For example, the image acquisition device may be provided on a vehicle mirror. After the image information of the driver is acquired, the image information of the eyes of the driver can be obtained by means of face recognition and eye extraction, for example.
In step 23, the pupil position of the driver is determined from the eye image information.
According to the acquired eye image information of the driver, the positions of the pupils of the driver can be identified by combining the image characteristics corresponding to the pupils.
In step 24, gaze angle information is determined based on the pupil position.
For example, the movement deviation direction of the pupil may be determined according to the determined pupil position with the pupil at the center of the eye as a reference, so that the gaze angle information may be determined. For example, if the pupil position gradually moves from the center of the eyes to above the eyes, it can be determined that the driver's sight line gradually moves upward, and thus the sight line angle information of the driver can be determined.
By the aid of the method, the sight angle information can be determined according to the eye positions of the driver and the positions of the pupils in the collected eye images, the actual visual field condition of the driver can be intuitively reflected, and the follow-up determination of the headlamp control strategy is more accurate.
The eye tracking means that the sight angle of the driver is tracked in real time, namely the sight angle information is acquired in real time. Illustratively, the eye tracking mode may include both an on mode and an off mode. The on mode refers to the vehicle turning on eye tracking function, and correspondingly, the off mode refers to the vehicle turning off eye tracking function. In addition to the above examples, other modes may exist for the eye tracking mode, for example, the on mode may include a plurality of modes, such as a first on mode and a second on mode, wherein the first on mode and the second on mode may correspond to different requirements of the user, for example, representing control for different headlamps.
In one embodiment, the eye tracking mode may be manually switched by the driver. For example, a switch for switching the eye tracking mode may be provided on the vehicle, and the switch may be triggered to switch the eye tracking mode, for example, to switch the eye tracking mode to the off mode, i.e., to turn off the eye tracking mode. If the driver switches the switch to the position of the on mode, the driver indicates that the eye tracking function is turned on, and the vehicle can receive a corresponding instruction, so that second information, namely the second information indicating that the eye tracking mode is the on mode, is determined. The switch may be a physical switch, for example, disposed on a steering wheel, a console, etc., for facilitating driver control. For another example, the switch may be a virtual switch displayed on a corresponding screen of the vehicle for the driver to select, and the virtual switch may omit the modification of the physical device, thereby saving the cost. In addition, the driver can also switch the eye tracking mode by voice, motion, or the like.
In another embodiment, the eye tracking mode may be switched automatically by the vehicle. For example, the vehicle may store a switching condition corresponding to the eye tracking mode, for example, when the vehicle speed reaches a first preset value, the vehicle speed is switched to an on mode, when the vehicle speed reaches a second preset value, the vehicle speed is switched to an off mode, when the driver makes a first preset action, the vehicle speed is switched to the on mode, when the driver makes a second preset action, the vehicle speed is switched to the off mode, and the like. The on condition (or off condition) may be set by the driver himself. By the mode, the operation that a driver manually switches the eye tracking mode in the driving process can be omitted, so that the driver concentrates on driving vehicles, and the driving safety is ensured.
For the case where the eye tracking mode includes a plurality of modes, for example, the eye tracking mode includes a first on mode, a second on mode and an off mode, and the switching manner is consistent with that described above, and the description is not repeated here.
Returning to fig. 1, in step 12, a target control strategy is determined based on the first information and the second information.
Wherein the target control strategy may be used to indicate an illumination angle of the vehicle headlamps. The illumination angle may be in any direction.
In one embodiment, if the second information indicates that the eye tracking mode is the off mode, the target control strategy is determined based on the eye position information and a correspondence between the pre-stored eye position information and the control strategy.
If the second information indicates that the eye tracking mode is the off mode, that is, the eye tracking function is not turned on, the target control strategy may be determined only according to the eye position information.
There may be various ways to determine the correspondence between the eye position information and the control strategy. For example, it may be manually set at the time of shipment of the vehicle, and for driver a and driver B, driver a is higher than driver B, and accordingly, the eyes of driver a are closer to above the vehicle than the eyes of driver B. Since the front body (vehicle front hatch) has a higher visual influence on the driver B than on the driver a, the irradiation angle of the headlamps with respect to the horizontal plane in the control strategy for the driver B may be slightly smaller than the irradiation angle of the headlamps with respect to the horizontal plane in the control strategy for the driver a, i.e., the control strategy for the driver B has a larger forward irradiation range of the headlamps than in the control strategy for the driver a, so as to increase the visual field range of the driver B. The eye positions can be set according to the eye positions, and the corresponding relation can be stored in the vehicle. For another example, the correspondence may be calibrated through multiple tests, and a corresponding unit (e.g., a controller) of the vehicle may store the calibrated relationship for use.
After the eye position information is determined, the target control strategy can be determined by combining the stored corresponding relation.
Through this kind of mode, confirm the control strategy to head-light irradiation angle according to the position at driver's eye place, can satisfy the driver's of different heights, different driving postures actual demand, the pertinence is stronger, can guarantee different drivers ' driving field of vision, can promote driving safety in the practical application.
In another embodiment, if the second information indicates that the eye tracking mode is the on mode, the target control strategy is determined according to the eye position information, the gaze angle information, and the pre-stored correspondence between the eye position information, the gaze angle information, and the control strategy.
If the second information indicates that the eye tracking mode is the on mode, that is, the eye tracking function is already on, the target control strategy may be determined by combining the eye position information and the gaze angle information. The corresponding relation among the eye position information, the sight angle information and the control strategy can be calibrated through a plurality of tests. The calibrated relationship may be stored for use by a corresponding unit (e.g., a controller) of the vehicle. For example, in the case where the target control strategy is determined, if the driver's gaze angle and/or eye position changes, the target control strategy may change accordingly. For example, if the pre-stored eye position information S1 and gaze angle information S2 correspond to the control strategy S3, the pre-stored eye position information S1 and gaze angle information S4 correspond to the control strategy S5, and it is detected that the gaze angle information is changed from S2 to S4, the target control strategy is changed from S3 to S5. For example, if the eye position information is not changed, the irradiation angle of the headlamp in the control strategy may change along with the change trend of the sight line angle information. For example, if the eye position information is not changed and the gaze angle information indicates that the driver gradually looks to the left, the illumination angle of the headlamp corresponding to the target control strategy may be adjusted to the left accordingly.
By the mode, under the condition that the eye tracking function is started, the irradiation strategy of the headlamp is determined by combining the eye position information and the sight angle information, so that the control strategy of the headlamp is closer to the real-time and actual requirements of a driver, and the safety can be ensured.
In step 13, the target headlamps are controlled according to the target control strategy.
In one embodiment, after determining the target control strategy, all headlamps of the vehicle may be taken as target headlamps, and all headlamps of the vehicle may be controlled in accordance with the target control strategy.
In another embodiment, the on-modes may include a first on-mode and a second on-mode, wherein the first on-mode may be multi-lamp control, i.e., control of a plurality of headlamps of the vehicle after the determination of the control strategy, and the second on-mode may be single-lamp control, i.e., control of a certain headlamp of the vehicle after the determination of the control strategy. In this embodiment, the method provided by the present disclosure may comprise the steps of:
determining all headlamps of the vehicle as target headlamps when the eye tracking mode is the first on mode;
and under the condition that the eye tracking mode is the second opening mode, determining the target headlamp according to the sight angle information and the corresponding relation between the prestored sight angle information and the headlamp.
In the case where the eye tracking mode is the first on mode, all headlamps of the vehicle may be determined as target headlamps.
If the eye tracking mode is the second on mode, if the gaze angle information of the driver indicates that the direction in which the driver focuses his gaze is biased to one side, the other headlamp does not greatly affect the current field of view of the driver, and the headlamp corresponding to the other side may not be turned on. For example, if two headlamps are arranged on the vehicle and are respectively located on the left side (headlamp 1) and the right side (headlamp 2) of the vehicle head, in the pre-stored corresponding relationship, the driver sight angle indicates that the driver sight attention direction gradually corresponds to the headlamp 1 leftward, and the driver sight angle indicates that the driver sight attention direction gradually corresponds to the headlamp 2 rightward, then, if the determined sight angle information indicates that the driver sight attention direction gradually approaches to the right, then the target headlamp can be determined to be the headlamp 2.
After the target control strategy and the target headlights have been determined, the target headlights may be controlled according to the determined target control strategy.
Through the mode, the headlamp needing to follow up is determined according to the attention direction of the sight of the driver, the control strategy of the headlamp far away from the attention direction of the sight of the driver is not changed, the control process is simplified, and the pertinence is stronger.
Through the scheme, the strategy for the irradiation angle of the headlamp is determined by combining the eye information of the driver and whether the eye tracking function is started, so that the headlamp of the vehicle is controlled according to the strategy. Therefore, the headlamp irradiation angle most suitable for the driver can be determined according to the actual sight line state of the driver, the visual field requirements of different drivers can be self-adapted, and the driving safety is improved.
