Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the individual features of the embodiments can be combined with one another without conflict.
Referring to fig. 1, fig. 1 is a flowchart of a driving simulation method according to an embodiment of the present invention. The simulated driving method comprises the following steps:
step S110: and determining a target parking space and acquiring a three-dimensional parking lot model of a parking lot where the target parking space is located.
When the target parking space is determined, the parking space which best meets the requirements of the user can be matched for the user according to the requirements of the user to serve as the target parking space, and the parking space which is directly input and selected by the user can be obtained to serve as the target parking space.
And after the target parking space is determined, obtaining a model of a three-dimensional parking lot of the parking lot where the target parking space is located. The three-dimensional parking lot model can enable a user to intuitively feel whether the actual size of the parking lot is appropriate or not according to the three-dimensional parking lot model, and therefore the user can be guaranteed to accurately select an appropriate parking space in the parking lot.
Step S120: acquiring parameters of a vehicle to be simulated, and establishing a corresponding three-dimensional vehicle model according to the parameters of the vehicle to be simulated; wherein, the scaling of the three-dimensional parking lot model and the three-dimensional vehicle model relative to the actual data is the same.
With the diversification of the models of the vehicles in the market, the vehicle models selectable by users become various, and because the models of the vehicles owned by different users are different, the parameters of the vehicle to be simulated can be obtained firstly before the simulated driving is carried out, and then the three-dimensional vehicle model is established according to the parameters. When the parameters of the vehicle to be simulated are obtained, the model of the vehicle to be simulated input by a user can be obtained from a vehicle parameter database, and the vehicle parameter database is all parameters of vehicles of different brands and different models which are established in advance. The user can also directly input parameters of the parameters to be simulated, or adjust the acquired vehicle parameters according to the vehicle model, and the like. For example, if the vehicle width of a certain user a is 1.7 meters, but it is relatively easy for the user a to stop the vehicle, the user a may modify the vehicle model number in the acquired parameters to 1.8 meters after inputting the vehicle model number. If the vehicle parameters of a certain user B are 1.7 meters in width, the parking technology of the user B is good, and the user B is not allowed to select a larger parking space by money, so that the user B can input the model of the vehicle, and when a three-dimensional vehicle model is established, the vehicle model can be simulated and established according to the parameters acquired by the input vehicle model.
In some embodiments of the invention, the step of obtaining parameters of the vehicle to be simulated comprises: acquiring a vehicle model input by a user; searching whether a vehicle model exists in a database, and if so, acquiring a parameter corresponding to the vehicle model; and if the vehicle model does not exist in the database, acquiring the vehicle model on the Internet.
Step S130: and acquiring an initial driving point, and placing the three-dimensional vehicle model in the three-dimensional parking lot model according to the initial driving point.
The initial driving point can be set according to the input of the client, and the initial driving point can also be preset. The entrance of the parking lot can be generally set as a preset initial driving point. When there are a plurality of entrances, the main entrance may be set as a preset initial travel point. The requirement of a customer on simulated driving can be met by acquiring the initial driving point, and the three-dimensional vehicle model is placed in the three-dimensional parking lot model according to the initial driving point. For example, if a customer wants to simulate driving from an entrance of a parking lot to a selected target space, the entrance of the parking lot may be selected as the initial driving point, and if a certain customer wants to simulate only parking in the target space, a certain point on a lane near the target space may be selected as the initial driving point.
Step S140: and acquiring driving data input by a user, and moving the three-dimensional vehicle model according to the driving data.
When the user carries out the simulated driving, the driving data is obtained according to the operation of the simulated driving. And then moving the three-dimensional vehicle model according to the input simulated driving data so as to achieve the purpose of simulating and driving the three-dimensional vehicle model in the three-dimensional parking lot model. When moving the three-dimensional vehicle model according to the driving data, it is necessary to convert the driving data input by the user into driving data corresponding to the scaling of the three-dimensional vehicle model and the three-dimensional parking lot model.
In the implementation process, the target parking space is determined firstly, and then the three-dimensional parking lot model of the parking lot where the target parking space is located is obtained. And then obtaining the vehicle parameters to be simulated, and establishing a three-dimensional vehicle model according to the vehicle parameters. And moving the three-dimensional vehicle model placed at the initial driving point of the three-dimensional parking lot according to the driving data input by the user. The method and the device can ensure that a user can simulate driving operation of the model which is zoomed according to actual data through the three-dimensional model, thereby ensuring that the parking space is accurately selected according to the driving simulation result.
Before the target parking space is determined and the three-dimensional parking lot model of the parking lot where the target parking space is located is obtained, the three-dimensional parking lot model can be obtained in various different modes, and the following modes are simply introduced.
First, a three-dimensional parking lot model may be obtained by first obtaining various parameters of the parking lot, such as the scale size of the parking lot, layout data in the parking lot, and the like. The initial frame of the three-dimensional parking lot model can be established in equal proportion according to the scale and size of the parking lot, for example, if the parking lot is a double-layer parking lot, a double-layer parking lot model initial frame can be established, if the parking lot is a single-layer parking lot, a single-layer parking lot model initial frame can be established, and then the initial frame is further filled according to layout data in the parking lot to obtain the three-dimensional parking lot model. For example, the specific positions of the structures such as the load-bearing columns and the wall surfaces in the parking lot can be obtained according to the layout data, the load-bearing columns and the wall surfaces can be proportionally arranged in the three-dimensional parking lot model according to the layout data, and the parameters of the parking lot further include the positions of all parking spaces, the size of each parking space and the like. When various parameters of the parking lot are acquired, the parameters can be acquired by acquiring a blueprint and a design construction drawing before the parking lot is established. But also by means of field measurements.
The second mode of obtaining the three-dimensional parking lot model can be achieved by firstly using the image acquisition equipment to shoot the panoramic video of the parking lot at a fixed moving speed, and the shooting height of the image acquisition equipment in the shooting process is consistent with the eye height of a driver on a vehicle. And then establishing a sphere model in the virtual space, and pasting the panoramic video to the inner side of the sphere through an editing sphere model shader to obtain the three-dimensional parking lot model.
The image acquisition equipment can be a panoramic camera, a three-dimensional laser scanner and the like. The type of the image acquisition device can be determined according to actual requirements, and the type of the image acquisition device is not limited herein.
Above-mentioned in-process of realizing, shoot through image acquisition equipment in the parking area and obtain the panoramic video, in order to guarantee the accuracy of panoramic video and can gather the real picture in parking area, image acquisition equipment shoots with fixed translation rate in time to when shooing panoramic image, highly setting up the camera shooting of image acquisition equipment in with the driver when driving eyes the height is the same on the vehicle. Therefore, the user can more accurately simulate the driving experience when simulating the driving.
In some embodiments of the invention, after the steps of obtaining driving data input by a user and moving the three-dimensional vehicle model according to the driving data, the method comprises:
and acquiring a display image according to a pre-established relation between the panoramic video picture change speed and the simulated driving signal, driving data and the three-dimensional parking lot model. Therefore, the user can watch the real picture of the parking lot, the sense of reality of the simulated driving is enhanced, and the immersive simulated driving experience can be realized.
In some embodiments of the present invention, before the step of obtaining the display image according to the relationship between the image change speed of the pre-established three-dimensional parking lot model and the simulated driving signal, the driving data, and the three-dimensional parking lot model, the method further includes: calculating the average acceleration value of the vehicle according to the dynamic parameters of the vehicle; calculating the acceleration of an accelerator, the acceleration of a brake and the current acceleration of the vehicle according to the simulated driving signal and the average acceleration value; calculating the current speed of the vehicle according to the current acceleration: and calculating a scene video playing rate coefficient according to the current speed and the attitude deflection angle so as to obtain the relation between the panoramic video picture change speed and the simulated driving signal.
In some embodiments of the present invention, after the step of obtaining driving data input by the user and moving the three-dimensional vehicle model according to the driving data, the method further comprises: and generating a collision prompt according to the condition that the three-dimensional vehicle model moves in the three-dimensional parking lot model.
In order to improve the reality of the simulated driving, when the three-dimensional vehicle model is moved according to the driving data input by the user, the situation that the three-dimensional vehicle model collides with a non-space part in the three-dimensional parking lot model possibly occurs, namely the situation that the three-dimensional vehicle model collides and scratches occur in the driving process, and at the moment, a collision prompt can be generated to remind a client.
In addition, when the three-dimensional vehicle model is moved according to the driving data input by the user, if the three-dimensional vehicle model moves to a preset reminding point in the three-dimensional parking lot model, voice prompt or picture prompt can be started, so that the user can know the condition of the parking lot more conveniently.
For example, if the height of the limit at a certain place in the parking lot may be low, a warning point may be set at the place to warn the user whether the height of the vehicle exceeds the limit. In addition, if a scratch accident easily occurs at a certain place of the parking lot, the place can be set as a reminding point to remind a user of paying attention, and the place is a scratch multi-occurrence area, so that the user can conveniently determine whether a target parking space is a proper parking space.
