[0043] The embodiments of the present application are described below through specific concrete examples, and those skilled in the art can easily understand other advantages and effects of the present application from the disclosure of the present specification. The present application can also be implemented or applied through other different specific embodiments, and each detail in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application.

[0044] Please refer to Figures 1 to 4It is to be noted that the drawings provided in the embodiments only schematically illustrate the basic concepts of the present application, and only show the components related to the present application, rather than the number, shape and size of the components in actual implementation. The shapes, number and proportions of the components in actual implementation can be arbitrarily changed, and the layout of the components can be more complex. The structures, proportions and sizes shown in the drawings of the present specification are only used to illustrate the content disclosed in the specification, so as to be understood and read by those skilled in the art, and do not define the limiting conditions for the implementation of the present application, and therefore do not have technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the present application, should still fall within the scope of the disclosed technology.

[0045] As shown in Figure 1 and Figure 2 The present application provides a vehicle automatic window breaking method, comprising:

[0046] Step S110: acquiring image data in the process of vehicle driving, the image data being obtained by an image acquisition module arranged on the vehicle, the image data comprising vehicle environment image and vehicle image.

[0047] In an exemplary embodiment, the image data can be obtained by a camera, and the camera is arranged on the roof of the vehicle. Four cameras are arranged on the roof, and the four cameras respectively obtain the front area, the rear area, the left side area and the right side area of the vehicle. In another exemplary embodiment, the camera can be arranged on the vehicle body by a camera support to obtain the image data. The arrangement position and arrangement mode of the image acquisition module can be adjusted according to the actual use condition.

[0048] Step S120: extracting the vehicle feature position, the detection surface feature position and the current vehicle three-dimensional envelope of the image data. If the vehicle is wading, the detection surface is the water surface, and if the vehicle is not wading, the detection surface is the driving surface.

[0049] It is to be noted that the vehicle wading includes driving or staying on the road surface with water or in the river, and the vehicle not wading is driving on the dry road surface.

[0050] In an exemplary embodiment, before extracting the vehicle feature position and the detection surface feature position of the image data, the image data is corrected and planarized.

[0051] In an example embodiment, since the vehicle is in the process of driving, the image data obtained by the vehicle can be perspective distorted, and it is difficult to effectively determine the spatial position relationship between objects. The image data is converted into an orthographic view by an IPM algorithm (Interior Point Methods) to ensure the accuracy of the position relationship between objects. After converting the image data into an orthographic view, the distortion caused by the camera angle in the image data can be eliminated, and the objects in the three-dimensional space are planarized in the two-dimensional image to obtain more accurate vehicle feature positions and detection surface feature positions.

[0052] In another example embodiment, since the vehicle is in the process of driving, the image data obtained by the image acquisition module can be affected by the quality and clarity of the image acquisition module, and the image in the image data can be blurred. The image acquisition module can use optical image stabilization (OIS) to reduce shaking by detecting the movement of the camera in the image acquisition module and applying a compensation offset to the lens or sensor. It can also use an algorithm implemented on an image signal processor (ISP) to eliminate severe shaking. The algorithm can be an electric image stabilization (EIS) algorithm. The above anti-shake methods are also known as digital image stabilization (DIS), electronic image stabilization (EIS), or video stabilization (VS).

[0053] Step S130: Compare the relative position relationship between the vehicle feature position and the detection surface feature position with the preset vehicle normal driving position relationship to obtain a compliance result.

[0054] In an example embodiment, the relative position relationship between the vehicle feature position and the detection surface feature position is compared with the preset vehicle normal driving position relationship to obtain a compliance result, including step S210.

[0055] Step S210: The image data includes a vehicle driving image of the vehicle driving image obtained from the vehicle side; the relative position relationship between the detection surface feature position and the vehicle feature position is compared; if the detection surface feature position is higher than the vehicle feature position in the image data or the vehicle driving image does not include the detection surface feature position, the compliance result is not compliant.

[0056] The preset vehicle normal driving position relationship includes the detection surface feature position and the vehicle feature position, and the detection surface feature position is lower than the vehicle feature position.

[0057] Step S140: comparing the total outer surface area and the unobstructed outer surface area of the current vehicle three-dimensional envelope to obtain the obstructed area rate.

[0058] The obstructed area rate is the difference between the total outer surface area and the unobstructed outer surface area of the current vehicle three-dimensional envelope divided by the total outer surface area of the current vehicle three-dimensional envelope.

[0059] Step S150: controlling the detonation device according to the coincidence result and the obstructed area rate, or controlling the detonation device according to the obstructed area rate to break the vehicle window glass 2.

[0060] In an exemplary embodiment, the detonation device is detonated according to the coincidence result and / or the obstructed area rate to break the vehicle window glass 2, including step S310.

[0061] Step S310: the coincidence result includes coincidence and non-coincidence; if the coincidence result is non-coincidence, and / or the obstructed area rate is greater than or equal to the preset obstructed area warning value, the vehicle window glass 2 is broken; if the coincidence result is coincidence, and the obstructed area rate is less than the preset obstructed area warning value, the detonation device does not act.

[0062] Breaking the vehicle window glass 2 through the coincidence result and / or the obstructed area rate can adapt to different accident scenarios and provide a self-help channel for the driver and passengers in time, improving the timeliness of the driver and passengers' self-help.

[0063] It should be noted that "up" and "down" used in the present application are relative terms, projected on the vehicle, the upper part of the vehicle is the roof, and the lower part of the vehicle is the wheel; projected on the external environment of the vehicle, the part close to the sky is the upper part, and the part close to the driving surface is the lower part.

[0064] As known from daily life, when the vehicle is not driving in water, the vehicle feature position should be above the detection surface feature position, and when the vehicle is driving in water, the vehicle feature position may be lower or higher than the detection surface feature position.

[0065] During the driving in water, there are several different situations:

[0066] The first situation is that the vehicle drives into a river, lake or sea due to a fault or other unexpected situations, and the vehicle window glass 2 is broken when the water level reaches the vehicle feature position; the second situation is that the vehicle drives on a road with accumulated water, and the vehicle window glass 2 is broken when the accumulated water rises and reaches the vehicle feature position; the third situation is that the vehicle accidentally falls into a river, lake or sea, and the vehicle window glass 2 is broken when the water level reaches the vehicle feature position. In the present embodiment, the vehicle feature position is the position where the vehicle is higher than the door sill line and moves upward by a preset breaking distance, and the selection of the vehicle feature position can be adjusted according to different vehicle categories and models.

[0067] Similarly, when the vehicle overturns, the up and down of the image data coordinate system obtained by the image acquisition module is reversed, the order of the vehicle feature position and the detection surface feature position is reversed, the relative position relationship between the vehicle feature position and the detection surface feature position changes after the reversal, the vehicle feature position is lower than the detection surface feature position, the conformity result is not in conformity, and the vehicle window glass 2 is broken; when the vehicle rolls over, one side of the vehicle faces the sky, so the vehicle driving image on this side does not include the detection surface feature position, the vehicle window glass 2 is broken to open a self-help channel for the driver and passenger.

[0068] In an exemplary embodiment, if the shielding area rate is greater than or equal to the preset shielding area, the vehicle window glass 2 is broken, including steps S410 and S420.

[0069] Step S410: Obtain the vehicle speed to obtain the instantaneous speed change rate of the vehicle.

[0070] Step S420: The preset shielding area warning value includes a preset maximum collision shielding area warning value and a preset maximum burial shielding area warning value; compare the instantaneous speed of the vehicle with the warning speed change rate; if the instantaneous speed change rate of the vehicle is greater than or equal to the warning speed change rate value, and the shielding area rate is greater than or equal to the preset maximum collision shielding area warning value, the vehicle window glass 2 is broken; if the instantaneous speed change rate of the vehicle is less than the warning speed change rate value, and the shielding area rate is greater than or equal to the preset maximum burial shielding area warning value, the vehicle window glass 2 is broken; wherein the preset maximum collision shielding area warning value is less than the preset maximum burial shielding area warning value.

[0071] In an example embodiment, if the vehicle suddenly collides, the collision object will block the outer surface area of the current vehicle three-dimensional envelope at the time of collision. The above-mentioned blocking can be the collision part of the vehicle at the time of collision, or the part of the vehicle buried after the collision occurs, or the part of the vehicle suddenly buried by external objects. After comparing the current vehicle three-dimensional envelope partially blocked with the preset vehicle three-dimensional envelope, the total outer surface area of the current vehicle three-dimensional envelope is compared with the unblocked outer surface area. The difference between the total outer surface area and the unblocked outer surface area is the blocked outer surface area of the current vehicle three-dimensional envelope. The quotient of the blocked outer surface area and the total outer surface area is the blocking area rate. Since a smaller blocking area rate during collision can also cause greater damage, the preset maximum collision blocking area warning value is smaller than the preset maximum buried blocking area warning value when determining. At the same time, since only the blocking area is determined during the collision, the probability of misjudgment is relatively large, for example, there are cloth blocks blocking the surface of the vehicle during driving. Therefore, the vehicle instantaneous speed change rate is added for auxiliary determination, which can increase the reliability of the collision scenario determination to a certain extent. In an example embodiment, a pressure sensor can also be provided on the vehicle to measure whether the stress received by the vehicle during impact is greater than the collision pressure warning value, thereby further increasing the reliability of the collision scenario determination.

[0072] It should be noted that during the water driving process, the part of the vehicle below the feature position of the detection surface is also displayed in a fuzzy state, which can be regarded as a blocked state. However, the image of the above-mentioned situation has a large difference from the image during collision and burying. For example, during water driving, the position of the water surface around the vehicle is relatively similar within a certain fluctuation range, so that the water driving can be distinguished from the collision and burying scenarios. At the same time, since the image data records the process of the water surface passing the feature position of the vehicle, the timing of breaking the window glass 2 can be accurately obtained. For another example, a water driving model can be established to analyze the vehicle body position and water body characteristics to identify whether the vehicle is located in the water.

[0073] In an example embodiment, after obtaining the image data during the driving of the vehicle, the step S510 is further included.

[0074] Step S510: identifying the flame by the pre-set flame identification model, marking the flame area, and breaking the window glass 2 if the distance between the flame area and the current vehicle three-dimensional envelope is less than the pre-set warning distance.

[0075] In an example embodiment, the flame in the vehicle image can be detected based on a convolutional neural network, and the flame area is marked. The above-mentioned radiation area is a radiation envelope wrapped around the preset vehicle three-dimensional envelope. The distance between any point on the radiation envelope and the preset vehicle three-dimensional envelope is the pre-set detection distance, which can be adjusted according to actual needs.

[0076] In an exemplary embodiment, before breaking the window glass 2, a window breaking start query is sent out, and a user breaking instruction is received, the window glass 2 is broken based on the user breaking instruction, and if the user breaking instruction is not received within a preset time after the window breaking start query is sent out, the window glass 2 is broken. The user is queried before the window glass 2 is broken to determine whether to break the window, which can avoid breaking the window after misjudging an accident situation, causing unnecessary economic losses to the user, and increasing the practicability and applicability of the vehicle automatic window breaking method. For example, the user is queried by an alarm sound or a human voice to determine whether to break the window, such as sending out the query “Do you need to break the window now?” If the user answers “Yes”, the window glass 2 is broken, and if the user answers “No”, no action is taken. Or, a vehicle control screen query prompt box is added to the above setting, such as prompting “Do you want to break the window glass 2? Yes / No”, if the user selects “Yes”, the window glass 2 is broken, and if the user selects “No”, no action is taken. When the user selects not to break the window glass 2, the event of breaking the window glass 2 is marked as a non-start event.

[0077] In an exemplary embodiment, a button for manually breaking the window glass 2 is provided on the vehicle, and the user can click the button to manually break the window glass 2 to fill the situation that the window glass 2 is not broken in time when the vehicle automatic window breaking method needs to break the window glass 2.

[0078] As described above, by comparing the relative relationship between the vehicle feature position and the detection surface feature position with the preset vehicle normal driving state position relationship, it can be determined whether the vehicle is in a normal driving state, whether a rollover, a tipping or a water landing occurs, and by obtaining the shielding area rate from the total outer surface area and the unshielded outer surface area of the current vehicle three-dimensional envelope, it can be determined whether a collision or a burial occurs. In this way, the window glass can be automatically broken in different accident situations to provide a self-help channel for the driver and passengers in time, and the success rate of self-help of the driver and passengers after an accident is improved.

[0079] As shown in Figure 3 and Figure 4 The present application provides a vehicle automatic window breaking system, comprising:

[0080] An image acquisition module, the image acquisition module is configured to acquire image data in the vehicle driving process, and the image data comprises a vehicle environment image and a vehicle image;

A relative position relationship between the vehicle feature position and the detection surface feature position is compared with a preset vehicle normal driving position relationship to obtain a coincidence result. A total outer surface area of the current vehicle three-dimensional envelope is compared with an unobstructed outer surface area to obtain an obstruction area rate. The initiation device is initiated according to the coincidence result and the obstruction area rate, or the initiation device is initiated according to the obstruction area rate to explode the vehicle window glass 2.

When the initiation device 3 is started, the heating element 303 heats the temperature-sensitive initiation substance 304 to make the temperature-sensitive initiation substance 304 initiate and push the initiation head 302 out of the opening to explode the vehicle window glass 2. A dust cover 301 is arranged at the opening of the containing shell 305. The dust cover 301 is made of a material that can be easily penetrated, such as paper or tin foil. The vehicle door has a vehicle door outer panel 1, the vehicle window glass 2 and a vehicle door inner panel 4 arranged in sequence along the thickness direction of the vehicle door. The initiation device 3 is arranged between the vehicle window glass 2 and the vehicle door inner panel 4. The heating element 303 can be a resistance wire. When the resistance wire is arranged on a heating circuit, the resistance wire generates heat when the heating circuit is turned on, and the temperature-sensitive initiation substance 304 is heated.
