Example 1
In this embodiment, with a mode of carrying out the projection on subaerial, show more vehicle information for the outer user of car, let the outer user of car more directly know the current state of car and the action that takes place, promote the security of car. The projection of information on the ground surrounding the vehicle reveals different colors and graphics to represent the state of the vehicle when static. The atmosphere lamp overcomes the defects of single function and deficient practical function of the existing atmosphere lamp, gives more information contents to the atmosphere lamp on the automobile body through the comprehensive expansion (whole automobile body) and graded information display of the display area of the atmosphere lamp around the automobile body, and can help people outside/in the automobile to know the current state of the automobile obviously and more visually, thereby avoiding unsafe events.
Based on a camera or a radar on a vehicle body as environmental data acquisition equipment, the judgment is carried out according to the state of the vehicle and the acquired data, and colors and graphs expressing different information are projected on the ground so as to enhance the safety and the interactivity of the vehicle in a static state.
Specifically, the present embodiment provides a multi-scenario application method for vehicle information projection, which includes the following steps,
s1: the acquisition module 100 acquires and transmits state data of the vehicle in real time;
s2: the processing module 200 receives the data of the acquisition module 100, converts the image data captured by the acquisition module 100 into distance parameters, captures an actual image through a camera, obtains the camera parameters by using camera calibration (converting pixel distance into actual distance) to obtain the pixel coordinates of the image, calculates the image pixel distance and space distance transformation formula, and converts the obtained pixel coordinates into actual space coordinates. Also for example, the internal parameters fc1, fc2, cc1, cc2 of the kit can be calibrated by matlab, where fc1= f/dx; fc2= f/dy; dx represents the actual distance represented by each pixel in the x direction, and the actual object distance is measured after dx and dy are calculated by using the parameter matrix of matlab (according to the number of the pixel points and the actual distance dx and dy corresponding to each pixel point).
S3: the distance parameter is transmitted to the subentry module 300;
s4: the sub-item unit 300 determines the scene status of the current vehicle by using the distance parameter identification, and determines the color and pattern to be projected. It should be noted that, in this step, the subentry unit 300 is implemented by using an image recognition classification algorithm, and only needs to recognize whether there are objects around the vehicle to classify the scene where the vehicle is located, and uses a neural network classifier, and an artificial neural network is referred to as Neural Network (NN) for short, which is an intelligent bionic model constructed based on the connection theory and is a nonlinear dynamical system composed of a large number of neurons. For the neural network, the findings are abstracted and simplified by researching, analyzing and summarizing the organizational structure and the activity rule of the human brain, so that a model established by the human brain is simulated. A non-linear mapping from the input space to the output space that "learns" or discovers relationships between variables by adjusting weights and thresholds allows the recognition and classification of objects. A large amount of data is used for training to improve the recognition accuracy, for example, the convolutional neural network fuses the distance parameter components in the embodiment to realize scene classification recognition.
Before proceeding with the display level narration, the subentry unit 300 needs to complete the following definition:
the itemizing unit 300 includes the following defining steps,
defining a safe distance D;
defining three distances D1, D2, D3, wherein D1< D2< D3;
defining a scene;
scene one: when the automobile is parked close to the side in a running state, the door of the automobile is opened;
scene two: the car is in a parking state, and a person/object with a threat approaches the car.
Further, the scheme for judging the scene state of the vehicle comprises,
the state of the vehicle defines the parking state and the driving state of the vehicle;
the parking state corresponds to that the vehicle is not started;
the door opening state corresponds to the operation of opening the door of a user in the vehicle.
According to the above definitions and scenario decisions, there are therefore:
the following steps are included in scenario one,
the door opening side recognizes that a pedestrian/non-motor vehicle approaches the rear part;
the light source emitting device is positioned at the side door skirt edge and projects red warning information on the nearby ground;
the warning message includes a warning that the doors of the side of the vehicle are opening for safety.
The following steps are included in the second scenario,
different threat levels are divided according to different distances relatively close to the vehicle body;
warning information with different threat levels is projected on the ground around the vehicle body to remind/warn people/objects with threats outside the vehicle.
S5: the projection generation module 400 projects colors and patterns on the ground.
The identification of the door opening side includes acquiring a camera image of the vehicle surroundings to determine whether a substance is present; if the substance exists, the distance between the substance and the vehicle is continuously monitored, and whether the substance is approaching or not is judged. The vehicle acquisition module 100 includes vehicle camera data, radar data, ultrasound data, and LIDAR data, wherein the vehicle camera data captures camera images of the vehicle surroundings through a lens of the vehicle camera, determines whether there is a substance around the vehicle, and continuously monitors the distance between the substance and the vehicle through the ultrasound radar, determines whether the substance is approaching.
In this embodiment, the safety distance D defined by the sub-item unit 300 preferably includes,
scene 1, D1=5 meters, D2=10 meters, D3=15 meters;
d1' =0.3 meters, D2' =0.5 meters, D3' =1 meter in scene 2;
in view of the foregoing scenarios, this embodiment needs to be described further.
Scene 1: testing according to the electric bicycle with the highest speed; 1. the testing speed is not more than v =25km/h for the design speed specified by the regulation; 2. the reaction time of the test person in the dangerous condition is t; 3. and d is the stopping distance of the brake.
Reaction time test average: t =0.45 sec
Brake distance test average: d =1.56 m
Distance from reaction to stop: d = v x t + D, test result about 4.71 meters;
in the limit, D1=5 m is taken to avoid collision; d2 and D3 are used as warning and reminding functions, and D2= 2X D1 is respectively taken in consideration of the avoidance behavior of the avoided pedestrian/non-motor vehicle; d3=3 × D1.
Scene 2: the distance is set mainly by considering whether the door of the other vehicle can touch the vehicle in the opening process after the other vehicle stops; a distance of about 1 meter is required for a common vehicle door to be fully opened; a half-open vehicle door needs 0.5 meter distance; the automobile interior passenger can be guaranteed to need 30 cm under the limit condition of getting off.
Therefore, in scenario 2, D1' =0.3 m, D2' =0.5 m, and D3' =1 m are set.
On the basis of the completion of the definition of D1, D2 and D3, the warning device is divided into three warning levels I1, I2 and I3 according to the prompt levels of the scene one and the two atmosphere lamps.
The sub-items according to the above alert level are as follows,
the I1 alert level includes the number of,
scene one: the rear threat object approaches the door opening side, the distance D is less than D1, and if the probability collision is more than 70%, the warning level is I1;
scene two: recognizing that a threat object approaches to the vehicle body, and judging that the distance between the threat object and the vehicle body is less than D1', wherein the warning level is I1;
the I2 prompt levels include that,
scene one: the rear threat object approaches the door opening side, the distance D1 is less than the distance D2, and the warning level is I2;
scene two: recognizing that a threat object approaches to the vehicle body, and if the condition that D1'< distance < D2' is met, the warning level is I2;
the I3 perception level includes the number of,
scene one: the rear threat object approaches the door opening side, the distance D2 is less than the distance D3, and the warning level is I3;
scene two: and recognizing that the threat object is close to the vehicle body, and if D2'< distance < D3', the warning level is I3.
Different display characteristics are adopted for projection display according to different levels, including,
i1, displaying by red light and warning patterns projected on the ground;
i2, displaying by yellow light and warning patterns projected on the ground;
i3 is shown by green light and warning patterns projected on the ground.
According to the method provided by the embodiment, a larger projection area is performed on the ground, and displayed information is graded to correspond to different reminding levels; the method is different from the traditional mode that the automobile displays information through the automobile lamp, is more visual and clear, and has strong expansibility. Through reforming transform some present vehicles are used for decorative effect's usher lamp, can be around the vehicle subaerial projection go out different warning information to inform outer user vehicle state and action, avoid for example opening the door in-process and take place the accident that rubs etc. because the user does not know the vehicle state emergence with the rear personnel, increase security and interactive, have more practical meanings.
