The invention determines the obstacle information through the view field image, so that the view field image can be adaptively adjusted according to the obstacle information and the running state of the vehicle, and the purpose of adaptively adjusting the view field of the external rearview mirror through the obstacle information is realized.
CMS: camera Monitor System is abbreviated to "camera-monitor system", and is generally referred to as an electronic outside rearview mirror system in automotive applications, in which a camera (camera) mounted on the left and right outer sides of a vehicle (at the left and right outside rearview mirror devices of a conventional vehicle) captures a field of view, further processes of image data acquisition and processing are performed by an Electronic Control Unit (ECU), and finally a display (monitor) provides the left and right outside rear fields of view for the driver, and meanwhile, corresponding early warning icons and distance auxiliary lines can be superimposed on a display screen to realize a driving auxiliary indication function by acquiring information such as blind area monitoring, steering, reversing, high speed, etc. of the whole vehicle.
Visual field self-adaption: the CMS controller receives the obstacle position information sent by the whole vehicle steering, vehicle speed, gear and ADAS obstacle detection sensor, comprehensively judges and carries out the up/down/left/right, compression and amplification self-adaptive adjustment of the outside rear view of the vehicle.
ADAS sensor: the sensor mainly refers to a camera, ultrasonic waves, millimeter waves, laser radars and the like which can provide position and azimuth information of the obstacle.
The adjustment principle is as follows: the FOV of the camera is fixed, the detectable range is fixed, but the resolution of the camera is 1920 x 1280, and the resolution of the display screen is 1280 x 720, so that there is necessarily a part of the acquired image of the camera which needs to be cut or compressed and then can be output to the display screen with 1280 x 720 resolution for display, and therefore, the image of the display screen can be adjusted up, down, left and right, so long as the adjusting range is not more than 1920 x 1280.
It should be understood that: the method can be applied to a system of a vehicle, an external rearview camera can be installed outside the vehicle, a CMS controller and a display screen can be installed, basic information (also called whole vehicle data) of the vehicle can be acquired through the CMS controller in the step S101, the external rearview camera can be assembled at the position of the outer ear of the traditional external rearview mirror and used for acquiring a visual field image of the external rearview mirror, after the visual field image is detected and processed by the CMS controller, the obtained target visual field image can be transmitted to the display screen, and the target visual field image is displayed on the display screen, so that the purposes of self-adaptive adjustment and display of the visual field image according to obstacle information are achieved.
It should be noted that: in order to adjust the view images correspondingly in different driving states of the vehicle, in some embodiments of the invention, the basic information includes vehicle speed information, steering information and gear information; the step S101 includes:
when the gear information is a forward gear, judging whether the speed of the vehicle is less than or equal to a first speed threshold value according to the speed information;
if yes, determining the running state of the vehicle according to the steering information;
if not, determining that the running state of the vehicle is a high-speed driving state.
In a specific embodiment of the present invention, the basic information of the vehicle may include vehicle speed information, steering information and gear information, the gear of the vehicle may be determined according to the gear information, whether the gear of the vehicle is a forward gear is determined, if yes, the vehicle speed of the vehicle may be determined according to the vehicle speed information, whether the vehicle speed is less than or equal to a first vehicle speed threshold, for example, the first vehicle speed threshold may be 80km/h, and a specific first vehicle speed threshold may be set according to an actual situation, where the embodiment of the present invention is not limited. If the vehicle speed is less than or equal to the first vehicle speed threshold value, the running state of the vehicle can be judged according to the steering information, and if the vehicle speed is greater than the first vehicle speed threshold value, the vehicle is in a high-speed driving state.
In some embodiments of the present invention, determining a driving state of a vehicle based on basic information includes:
and when the gear information is the reverse gear, determining that the running state of the vehicle is a reverse driving state.
In a specific embodiment of the present invention, when the gear of the vehicle is not a forward gear, it may be determined whether it is a reverse gear, and if so, it may be determined that the running state of the vehicle is a reverse driving state.
In some embodiments of the present invention, determining a driving state of a vehicle according to steering information includes:
judging whether a steering lamp is turned on or not or whether the steering angle of the vehicle is larger than a first steering wheel corner threshold value according to the steering information;
if yes, determining that the running state of the vehicle is a steering driving state;
if not, the running state of the vehicle is determined to be the normal driving state.
In a specific embodiment of the present invention, the steering information may include whether the vehicle turns on the steering lamp and the steering wheel angle, and when the vehicle speed of the vehicle is less than or equal to the first vehicle speed threshold, it may be determined whether the vehicle turns on the steering lamp according to the steering information, or it may also be determined whether the steering angle of the vehicle is greater than the first steering wheel angle threshold, for example, the first steering wheel angle threshold may be 60 °, and the specific first vehicle speed threshold may be set according to the actual situation. When the turn signal of the vehicle is on or the steering angle is greater than the first steering wheel angle threshold, it indicates that the vehicle is in a steering driving state, and if not, it indicates that the vehicle is in a normal driving state.
In some embodiments of the present invention, step S102 includes:
acquiring radar data of a vehicle;
and fusing and identifying the radar data and the visual field image to obtain barrier information.
In the specific embodiment of the invention, the vehicle can acquire radar data of the vehicle through an ultrasonic radar, a millimeter wave radar and the like carried by the ADAS, and can also fuse and identify the radar data of the vehicle with the view field image so as to acquire barrier information.
In some embodiments of the present invention, fusing radar data with a field of view image to obtain obstacle information includes:
determining first information of the obstacle according to the radar data;
identifying the view field image to obtain first coordinate information of the obstacle in a coordinate system taking the phase of the central point of the optical axis of the camera as the origin of coordinates;
converting the first coordinate information into a coordinate system taking the center of a rear axle of the vehicle as an origin of the coordinate system to obtain second coordinate information;
determining second information of the obstacle according to the second coordinate information;
and obtaining barrier information of the barrier according to the first information and the second information.
In a specific embodiment of the present invention, first information of an obstacle may be determined according to radar data, for example, the first information may be azimuth information where the obstacle is located, etc., a view image of an exterior rearview mirror is an image acquired by taking a plane of a center point of an optical axis of a camera as a coordinate origin, and includes coordinate positions of each region, detection of the obstacle may be performed on the view image to obtain first coordinate information of the obstacle, a camera may be taken as a whole, a center of a rear axle of a vehicle may be taken as a coordinate origin (i.e., a center point of a rear wheel connecting line), a coordinate position of the camera relative to the coordinate origin may be obtained, and then coordinate conversion may be performed on the first coordinate information of the obstacle according to the coordinate position of the camera to obtain second coordinate information of the obstacle in a coordinate system taking the center of the rear axle of the vehicle as the coordinate origin, and then the second information of the obstacle may be determined according to the second coordinate information, for example, a distance between the obstacle and a rear wheel may be determined.
In some embodiments of the present invention, step S103 includes:
and when the driving state is the normal driving state, cutting a preset range of an adjacent lane where the vehicle is driven in the view field image according to the obstacle information to obtain an initial view field image.
In a specific embodiment of the present invention, when the driving state is a normal driving state, for example, the gear is D, the vehicle speed < = 80km/h, and no steering is performed (the steering angle is <60 °, or the driver does not turn on the steering switch, and no steering intention is performed), then the preset range of the adjacent lane where the vehicle is driving in the visual field image can be cut according to the detected obstacle information, for example, in the normal driving state, only the lane +1/3 more beside the adjacent lane where the vehicle is driving can be observed, then the size that the display screen can show can be cut out in the corresponding position in the visual field image in a cutting manner, for example, 1280×720, and no compression is required here, so that the distance between the real object and the vehicle is better, thereby obtaining the initial visual field image.
In some embodiments of the present invention, step S103 includes:
when the driving state is a reversing driving state, determining a first area of the visual field image according to the obstacle information; the first area is an area below the visual field in the visual field image;
and compressing the image of the first area to obtain an initial view image.
In a specific embodiment of the present invention, the area of the view image may be determined based on the detected obstacle information, for example, when the obstacle information is at the lower left of the view image, the area at which the obstacle is detected at the lower left may be determined as the area; in contrast, in the case where the vehicle is in a reverse driving state, the parking space and the vehicle are desired to be seen, and the surrounding visual field is desired to be larger, the visual field image is compressed, the visual field range is enlarged, and the visual field is simultaneously adjusted downward.
In some embodiments of the present invention, step S103 includes:
determining a second area of the view image according to the obstacle information when the driving state is a high-speed driving state; the second area is an area above the visual field in the visual field image;
and compressing the image of the second area to obtain an initial view image.
In the specific embodiment of the invention, when the driving state is a high-speed driving state, the gear is D gear, the vehicle speed is more than 80km/h, the expected visual field range is enlarged, meanwhile, the visual field is deviated upward (because the general high-speed vehicle distance is larger, wheels and the road surface occupy most of the picture of the display screen if the vehicle is deviated downward, the safe driving of a driver is not facilitated), a second area which is deviated upward can be determined by taking the camera image from the compression center point of the visual field, then the image of the second area is compressed, and an initial visual field image is obtained, and the visual field range of the display screen is deviated upward and is enlarged.
Further, when the driving state is a steering driving state, that is, when the steering lamp of the vehicle is turned on or the steering angle is greater than 60 °, the mode of the obtained initial view image is consistent with that when the driving state is a high-speed driving state, wherein the process of compressing or clipping the view image is as shown in fig. 2, the left image is the view image, the original resolution of the view image is 1920×1536, after the region clipping, the image on the right can be obtained, the resolution can be 1920×1080, the image on the right can also be compressed, and the image on the right can be obtained, and the resolution is 1280×720.
In some embodiments of the present invention, after step S103, further comprising:
when the view image detects an obstacle and no obstacle exists on the initial view image, the information of the obstacle on the view image is output to prompt the existence of the obstacle in the blind area.
In a specific embodiment of the present invention, when an image is detected, an original view image may be used, the view image is not cut, the resolution is higher, and more information is included, when the view image detects an obstacle and no obstacle exists on the original view image, it indicates that an obstacle exists in a blind area of the view outside the display screen, and according to the detected obstacle, a prompt message of the existence of the obstacle in the blind area may be output, and further, the update of the obstacle distance information may be updated in real time, for example, the update of the obstacle distance value on the CMS display screen may be performed, where the specific prompt message may be set according to the actual situation.
In some embodiments of the invention, the first information is position information of the obstacle; the second information is distance information of the obstacle: step S104 includes:
determining the target position and the target distance of the obstacle in the vehicle according to the azimuth information and the distance information;
and drawing a distance auxiliary line on the initial view image according to the target position and the target distance to obtain a target view image.
In a specific embodiment of the present invention, the target azimuth of the obstacle in the vehicle may be determined according to the azimuth information, the target distance between the obstacle and the vehicle may be determined according to the distance information, and further, the specific position of the obstacle corresponding to the vehicle may be determined according to the target azimuth and the target distance, and further, distance auxiliary line drawing may be performed on the initial view image according to the target position and the target distance, so as to obtain the target view image, the initial view image may be input into the image processing software, and auxiliary lines may be drawn according to the requirement, where the auxiliary lines may be drawn according to the distance, for example, as shown in fig. 3, one line may be drawn 30cm from the vehicle body, one line may be drawn 70cm from the vehicle body, etc., and the specific method of drawing the auxiliary lines may be set according to the actual situation.
