Detailed Description
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
The host computer of the vehicle is an interactive device integrated in the central control position of the vehicle, and can realize the display of vehicle information and the input of driver control. The driver generally touches a graphical key (also called a soft key or a soft switch) in the host to input a control signal. The driver touches the host computer when driving and has certain potential safety hazard, and especially when the figure button is more, and the display area is less, the driver can't accurately find the region that the button that wants to control corresponds, can't accomplish fast and control. The present invention has been devised in view of the above circumstances. The technical solution of the present invention will be described in detail below with reference to a plurality of drawings.
Fig. 1 is a flowchart of a vehicle display control method. As shown in fig. 1, the vehicle display control method includes:
s101, acquiring a target area corresponding to the sight line of a driver on a current User Interface (UI) displayed by a vehicle host.
Wherein the target area is configured to track the driver's eye. Here, it should be noted that, in the present embodiment, by acquiring an image including a position of a driver eyeball and combining with an eyeball positioning technology, it is determined that the driver eyeball corresponds to a target area on the UI.
In a preferred embodiment, fig. 2 is a flowchart of acquiring the target area, as shown in fig. 2.
S201, acquiring a plurality of frames of face images of a driver in a continuous time, wherein the face images of the driver are configured to comprise head gestures and eyeball features. The multi-frame driver face image is collected through a camera and is a driver face image containing eyeballs of a multi-frame image sequence in continuous duration. Wherein, the effectiveness of the collected image is ensured by removing the image which does not contain the eyeball in the collected face image of the driver. The driver face image is configured to include a head pose and an eyeball feature. Wherein the head posture is used for representing the head steering angle of the driver, and the eyeball characteristic is used for representing the rotation angle of the eyeball of the driver.
S202, calculating the eyeball movement angle of the driver based on the head posture and the eyeball characteristics. Wherein, the eyeball orientation of each frame of driver can be calculated based on the head posture and the eyeball characteristics in the image of each frame, and the eyeball moving angle of the driver can be obtained based on the facial images of the driver of a plurality of frames.
S203, determining a target area of the driver, which is watched on the current user interface of the vehicle host machine, based on the eyeball movement angle. The target area exists on a UI of the vehicle host.
Specifically, the eyeball target rectangular coordinate sequence can be acquired through S101:
[(x1，y1)，(x2，y2)，...(xn，yn)，...(xN，yN)]，N≥2；
the eyeball-movement angle θ is calculated by the following formula:
Figure BDA0002476885350000051
wherein the slope k is calculated once every Z framesnTo obtain a total number M of angular sequences:
[α1，α2，...αm，...αM]；
wherein the content of the first and second substances,
Figure BDA0002476885350000052
α＝arctan(kn)，1≤z≤10。
each angle of eye movement corresponds to a target position of the UI that reflects the driver's visual position.
Further preferably, in order to simplify the calculation process and avoid an excessive load of the controller, the calculation steps of S202 and S203 are started when the driver is substantially gazing at the host.
Although the target area of the driver has been obtained and the visual position of the driver is determined, it is not clear which target area needs to be enlarged. If it is exactly which key the driver looks at, a highly precise eyeball positioning technology is required. However, since the current eyeball positioning technique with high precision is too expensive and the placement position cannot be adapted to the vehicle requirement, the present embodiment leads to S102 described below.
And S102, acquiring an area matched with the target area from a plurality of areas pre-divided in the UI as a key area.
The UI is pre-divided into a plurality of regions to match the above-mentioned eyeball location technique (location is not particularly accurate). And taking one area as a reference area to be amplified, and further reducing the probability of errors in positioning. For example, when the eyeball of the driver is located in the area of three continuous keys of radio, multimedia and air conditioner, since the eyeball location technology adopted at the present stage is not accurate enough, it is impossible to know which position the specific location is, and if the location is determined randomly, it is likely that the final key area is located at the multimedia position, but actually what the driver wants to turn on is the key at the air conditioner position. Therefore, the present embodiment can be applied to an eye positioning technique with low accuracy (e.g., the positioning technique of the present invention), and is more suitable for an eye positioning technique with high accuracy.
Specifically, in this embodiment, the division of the plurality of regions may be an average division, or may be set according to actual needs. For example, the radio, multimedia and air conditioner are set as one area, the telephone and mobile phone connection is set as one area, and the specific setting mode can be adjusted.
Further preferably, in the present embodiment, based on a hash code algorithm, a plurality of pre-divided areas in the UI are scanned to calculate a respective first hash code for each scanning window (area). And scanning the target area to obtain a second hash code. And selecting a first hash code with the minimum Hamming distance from the plurality of first hash codes to the second hash code, and taking the area corresponding to the first hash code as a key area, namely the area to be amplified.
And S103, amplifying and displaying the key area in the UI.
Wherein, the UI takes an 8-inch display screen as an example, and the length of the 8-inch display screen is 162.56mm-177 mm. If the key area of the driver is positioned to be the area consisting of the radio reception key, the multimedia key and the air conditioner key, the key area comprising the three keys is displayed in an enlarged mode in the UI.
Further preferably, the enlarged display is specifically that the key area is enlarged and displayed in the current user interface according to a preset enlargement ratio. For example, the enlargement ratio is set to 2 or 3. The user can make settings as desired.
Further preferably, after S103, the vehicle display control method further includes: and responding to the touch operation of the driver on the key area after the enlarged display, and controlling the vehicle to execute the key function related to the touch operation. The touch operation is an operation of clicking the key area by a driver. The width of the adult index finger is 150mm +/-3 mm, and the size of the key can be set according to the width.
Further preferably, it is determined that the driver has a touch operation if the following condition is satisfied: the area of the driver's finger pressing on a key is greater than a preset area threshold, wherein the area threshold is configured as the product of the current area of the key and 60%.
And the area of the current key is the enlarged area of the key. According to the further preferable scheme, the operation of the driver after the key is amplified can be facilitated, and the response range is expanded. For example, if the key has an area of 4cm before enlargement2Then its area responding to the driver's touch operation is only 4cm2And after the key is enlarged, the area of the key is changed into 8cm2The area thereof responding to the touch operation of the driver also becomes 8cm2The user operation becomes simpler.
Fig. 3 is a further preferred embodiment of the vehicle display control method, which further includes, before S101, as shown in fig. 3:
s301, judging whether a vehicle host is in a night mode, wherein the night mode is configured to be triggered to start when the external ambient light intensity of the vehicle is smaller than a preset light intensity threshold value and a vehicle lamp is activated.
And S302, under the condition that the vehicle host is in the night mode, executing the step of acquiring the target area watched by the driver on the UI of the vehicle host.
In the night mode, the driver needs more concentration, and unsafe factors are further increased due to too small keys. At present, in the night mode, the brightness of the UI is adjusted according to the setting of the user, and generally, the brightness of the UI is increased, so that the night mode not only increases the brightness of the UI but also increases the area of the key area watched by the user. For example, when it is recognized that the ambient light level of the outside is too dark and the driver turns on the vehicle lamp, the target area starts to be acquired, so that the present embodiment is more targeted.
Through the embodiment, in the night mode, the target area watched by the driver on the UI is acquired, the key area corresponding to the target area is acquired from the plurality of pre-divided areas according to the target area, and the display control of the vehicle host is realized through the amplified display of the key area. The graphical key under the navigation interface becomes smaller, if the scheme of the embodiment is not used, the key touch can be completed only by the driver with more attention after the graphical key in the UI is further reduced, and further more unsafe factors are brought.
Fig. 4 is a block diagram of a vehicle main unit of the present invention, and as shown in fig. 4, the vehicle main unit is provided with a controller 41, and the controller 41 is configured to execute the vehicle display control method of fig. 1, 2, and 3.
Further preferably, the vehicle main unit further includes: a camera 42 for transmitting a plurality of frames of driver face images captured within a duration to the controller 41 in response to an image capturing operation of the controller, wherein the driver face images are configured to include a head posture and an eyeball feature.
The vehicle host is a multimedia host of the vehicle. The camera, preferably a Driver Monitor Status (DMS) unit for monitoring the driving state of the Driver, is used by a main user to Monitor whether the Driver is in a fatigue state.
The local amplification technology of the UI interface of the multimedia display screen can be realized by replacing a brand new UI interface, namely, the original interface is replaced without amplification on the original interface, but the switching speed needs to be considered, so that a client cannot perceive the interface by naked eyes.
Compared with the prior art, the vehicle host machine and the vehicle display control method have the same advantages, and are not repeated herein.
