With continued reference to FIG. 2, a flow 200 of one embodiment of a method for outputting information in accordance with the present disclosure is shown. The method for outputting information of the embodiment comprises the following steps:
In this embodiment, set up in the image acquisition device of parking area and can gather the image of target parking stall in real time. And transmits the acquired image to the execution subject. After receiving the image, the execution main body can detect whether the vehicle drives into the target parking space. Specifically, the executing subject may perform object detection on the image to determine the position of the vehicle. And if the coincidence degree of the position of the vehicle and the target parking space is greater than the threshold value, the vehicle is considered to be driven into the target parking space. Or, the execution subject may analyze each position of the vehicle to determine whether the wheel is driven into the target parking space.
If the execution main body detects that the vehicle drives into the target parking space, whether the vehicle normally stops in the target parking space can be judged. Specifically, the execution subject may determine whether the vehicle body is located outside the target parking space when the vehicle stops. Or judging whether the size of the vehicle body part outside the target parking space is larger than a preset threshold value. If so, the vehicle is considered to be abnormally stopped.
If the execution subject determines that the vehicle is not normally parked in the target parking space, an abnormal parking type of the vehicle may be further determined. In this embodiment, the abnormal parking type may include a plurality of types, and may include, for example, an oblique parking, a striding parking, and a reverse parking. The oblique parking refers to that the vehicle is parked in the target parking space obliquely, namely, the included angle between the center line of the vehicle in the driving direction and the center line of the target parking space in the length direction is an acute angle. The striding parking refers to that the vehicle strides and stops in the target parking space and the adjacent parking spaces. The reverse stop means that the vehicle is oriented opposite to the target parking space. Specifically, the executing subject may first determine, according to the image, the heading and the heading of the head and the tail of the vehicle, the position of the vehicle, and the heading and the position of the target parking space and the surrounding parking spaces. The information is compared, so that the abnormal parking type can be determined.
And step 203, responding to the fact that the preset information pushing condition is met, and outputting prompt information based on the abnormal parking type.
After determining the abnormal parking type of the vehicle, the execution subject may monitor whether a preset information push condition is satisfied. Here, the preset information push condition may be set according to an actual application scenario, and may include, but is not limited to: the duration of the vehicle standing still at the same position exceeds the preset duration, the driver of the vehicle leaves the vehicle, and the vehicle enters the target parking space for the preset duration.
If the information pushing condition is met, the execution subject can output prompt information based on the abnormal parking type. For example, the execution subject may output the type of abnormal parking, the position where the vehicle is located, and the like as the prompt information. In this way, the owner of the vehicle or the manager of the parking area can further process according to the prompt information.
With continued reference to fig. 3, a schematic diagram of one application scenario of a method for outputting information according to the present disclosure is shown. In the application scenario of fig. 3, a camera 301 in a parking area acquires an image of a target parking space, and uploads the image to a server 302. After detecting that the vehicle enters the target parking space, the server 302 confirms that the vehicle is parked in the target parking space in an inclined manner. After confirming that the driver leaves the vehicle, the driver determines that the vehicle can not move any more, and sends prompt information to the terminal 303 held by the vehicle owner to prompt the vehicle to obliquely stop in the target parking space and guide the vehicle owner to stop according to the specification.
According to the method for outputting the information, provided by the embodiment of the disclosure, the information can be output to remind the owner when the owner parks the vehicle abnormally, so that the standard degree of parking is improved.
With continued reference to fig. 4, a flow 400 of another embodiment of a method for outputting information in accordance with the present disclosure is shown. As shown in fig. 4, the method of the present embodiment may include the following steps:
In this embodiment, the execution subject may obtain the image of the target parking space in real time from the image acquisition device connected in communication. In some specific application scenarios, the image capturing device may be arranged at a fixed position. Therefore, the position of the target parking space in the image acquired every time is unchanged, and subsequent processing is facilitated.
After the execution subject acquires the image, the execution subject may analyze the image to determine the position of the wheel of the vehicle. Specifically, the execution subject may perform target detection on the image to determine the vehicle position. And then, extracting characteristic points of the area where the vehicle position is located, and determining the position of the wheel. Alternatively, the execution subject may perform instance segmentation on the region where the vehicle position is located, and determine a binary map of the vehicle. A wheel region is determined from the binary map, and then a wheel position is determined.
The position of the target parking space is fixed in the image acquired each time. Technicians can mark the images collected by the image collecting equipment in advance, and set the marking frame as the position of the target parking space. Then, the execution subject may determine the position relationship between the wheel and the target parking space according to the position of the wheel and the position of the target parking space. And if the position of the wheel is positioned in the target parking space, the vehicle is determined to drive into the target parking space. And if the position of the wheel is outside the target parking space, determining that the vehicle does not drive into the target parking space.
In this embodiment, the executing entity may first determine a first profile of the vehicle and a second profile of the target parking space, respectively. And then, respectively extracting first key points from the first contour of the vehicle and extracting second key points from the second contour of the target parking space. And respectively converting the first key point and the second key point from the image coordinate system to a world coordinate system, thereby obtaining the positions of the vehicle and the target parking space in the world coordinate system and completing the simulation three-dimensional modeling. In the modeling process, to reduce the amount of computation, the vehicle may be modeled as a rectangular parallelepiped or other easily computed cube.
In the world coordinate system, the executing bodies may respectively project the cube in which the vehicle is located toward the ground, and determine the projection area of the vehicle. And calculating the overlapping area of the projection area of the vehicle and the target parking space. And if the proportion of the overlapping area to the area where the target parking space is located is greater than a first preset threshold value, the vehicle is considered to be normally parked in the target parking space. And if the proportion of the overlapping area to the area where the target parking space is located is smaller than a second preset threshold value, the vehicle is considered not to be normally parked in the target parking space.
Through the three-dimensional modeling of the embodiment, the relation between the vehicle and the target parking space can be judged more accurately, and therefore the parking state of the vehicle can be determined more accurately.
And step 403, in response to determining that the vehicle is not normally parked in the target parking space, determining an abnormal parking type of the vehicle.
In this embodiment, if the execution subject determines that the vehicle does not normally stop in the target parking space, it may be determined that the vehicle currently belongs to an abnormal parking, and the abnormal parking type may be further determined. The abnormal parking types may include a first type, a second type, and a third type. The first type, the second type and the third type can be oblique parking, cross parking and reverse parking.
In some optional implementations of the present embodiment, the execution subject may determine the abnormal parking type by: determining an included angle between a center line of the vehicle in the driving direction and a center line of the target parking space in the length direction; and determining that the abnormal parking type of the vehicle is a first type in response to determining that the included angle is within a preset angle range.
In this implementation manner, specifically, the executing body may first determine an included angle between a center line of the vehicle in the driving direction and a center line of the target parking space in the length direction. The driving direction can be the direction between the head and the tail of the vehicle or the direction between the tail and the head of the vehicle. Generally, the target parking space is rectangular, and when the vehicle normally stops in the parking space, the center line of the vehicle in the traveling direction is parallel to the center line of the vehicle in the longitudinal direction. I.e. the angle between the two centre lines is 0 degrees or 180 degrees. In this embodiment, in consideration of the fact that the vehicle is slightly inclined without affecting the parking of other vehicles, it may be determined whether the included angle is within a preset angle range. If so, the abnormal parking type can be determined as the inclined parking.
In some optional implementations of the present embodiment, the execution subject may determine the abnormal parking type by: in response to determining that the vehicle occupies the target space and at least one space adjacent to the target space, determining that the abnormal parking type of the vehicle is a second type.
In this implementation manner, if the execution subject determines that the vehicle occupies the target parking space and the parking spaces adjacent to the target parking space at the same time, it may be determined that the abnormal parking type of the vehicle is the second type, which may also be referred to as stop-crossing. Specifically, the execution subject may project the vehicle, the target parking space, and the parking spaces adjacent to the target parking space to the two-dimensional coordinate system in the model obtained by the three-dimensional modeling. And if the projected area of the vehicle occupies the projected areas of the target parking space and the adjacent parking spaces, the vehicle is determined to be parked in a crossing way.
In some optional implementations of the present embodiment, the execution subject may determine the abnormal parking type by: and in response to determining that the orientation of the vehicle is opposite to the orientation of the target parking space, determining that the abnormal parking type of the vehicle is a third type.
The situation of this implementation is applicable to parking areas, such as roadside areas, where the orientation of the target parking space is limited. The execution subject can determine the orientation of the vehicle by extracting the feature points of the vehicle. And if the executing subject detects that the direction of the vehicle is opposite to the direction of the target parking space, the abnormal parking type is considered as reverse parking.
And step 404, identifying the license plate number of the vehicle, and immediately sending the abnormal parking type to a preset person associated with the license plate number.
In this embodiment, the execution subject may identify the license plate number of the vehicle after determining the abnormal parking type of the vehicle. Specifically, the execution subject can recognize the license plate number of the vehicle through the existing image processing mode. And then, an abnormal parking type is sent to a preset person associated with the license plate number in real time, so that the vehicle owner can know the parking condition in time and adjust the position of the vehicle in time. It can be understood that the execution subject may obtain the contact information of the preset person associated with the license plate number by querying the database. The abnormal parking type can be sent in a short message mode or in a pop-up box mode of an application program.
In this embodiment, the execution main body may monitor whether the information push condition is satisfied in real time. The above information push condition may be understood as a condition for confirming that the vehicle does not move any more. If the driver of the vehicle leaves the vehicle, the vehicle is considered not to move any more, and the information pushing condition is met. And if the stop time of the vehicle is longer than the preset time, the vehicle is defaulted not to move any more, and then the information pushing condition is determined to be met. When determining the stop time of the vehicle, the execution subject needs to periodically acquire images from the image acquisition device, analyze the images and determine whether the position of the vehicle changes. If the position of the vehicle has not changed, the current time length from the moment the vehicle stops at the position, that is, the stop time length, can be calculated.
It can be understood that images of the target parking space need to be acquired regularly, so that the system can help a vehicle owner to determine whether the vehicle normally stops in the target parking space in real time, and the situation that whether the vehicle owner cannot accurately judge whether the vehicle normally stops in the target parking space due to unfamiliarity of the vehicle owner with the parking environment is avoided.
And step 406, in response to determining that the preset information pushing condition is met, outputting prompt information based on the abnormal parking type.
In this embodiment, the above prompt information can be output to the car owner and the parking lot manager at the same time, so that the car owner can adjust the position of the car in time, and the parking lot manager can stop the abnormal parking behavior in time.
In this embodiment, if the vehicle normally stops in the target parking space, the parking information may be sent to the preset personnel associated with the license plate number in real time. The parking information may include a license plate number, a time when the vehicle stops at the target parking space, a position where the vehicle is located, at least two images of the vehicle stopping at the target parking space, and the like.
In some optional implementations of the present embodiment, the prompt message in step 406 may include the parking information in step 407 and the abnormal parking type.
The method for outputting the information provided by the embodiment of the disclosure can accurately judge the relationship between the vehicle and the target parking space according to the three-dimensional modeling technology. And when the normal parking of the vehicle is determined, the parking information is sent immediately. When the abnormal parking of the vehicle is determined, the abnormal parking type is sent in real time to remind the vehicle owner to move the vehicle in time, and the standard parking is realized. And just output prompt message after the vehicle is determined to be stopped stably and can not move any more, so that the situation that the vehicle reminds a parking lot manager in the moving process of a target parking space and causes useless information pushing can be avoided.
