Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
According to one aspect of the invention, an auxiliary parking method is provided for judging whether the current position of a vehicle belongs to a time-limited parking area or not so as to remind a user of driving away from the current position when the parking time is about to reach.
In one embodiment, as shown in the flowchart of fig. 1, the parking assist method 100 includes steps S110 to S130.
Wherein, step S110 is: and judging whether the current position of the vehicle belongs to a time-limited parking area.
The current position refers to a position where the vehicle is currently located. The present invention is directed to determining whether or not the position of a vehicle in a parking state or a preliminary parking state belongs to a time-limited parking area, and therefore, preferably, the current position of the vehicle includes the parking position of the vehicle in the parking state and the position of the vehicle in which a driver of the vehicle intends to park.
The time-limited parking area refers to an area used as a parking place for some period of time. The time-limited parking area has a corresponding effective time interval, and generally, the corresponding effective time interval may be marked on a mark indicating the parking area.
Step S120 is: and judging whether the vehicle needs to drive away or not in response to the fact that the current position of the vehicle belongs to the time-limited parking area.
It can be understood that when the current position of the vehicle belongs to the time-limited parking area, if the vehicle is in a parking state, whether the current time is close to the stop parking time needs to be judged, and the vehicle needs to drive away before the stop parking time comes; if the vehicle is in the ready-to-park state, whether the current time is close to or exceeds the cut-off parking time needs to be judged, and the vehicle needs to drive away before the cut-off parking time or immediately.
Specifically, it may be determined whether the vehicle needs to be driven away based on a comparison of the deadline for the valid time interval of the time-limited parking area and the current time.
Step S130 is: and generating reminding information to remind a user of driving away as soon as possible in response to the judgment that the vehicle needs to be driven away.
It can be understood that when the vehicle is in a non-flameout state, the reminding information can be displayed through the central control display screen or the instrument display screen so as to be received by the user conveniently. Preferably, in order to prevent the vehicle from being in a parking state and prevent the user from being unable to receive the information when the vehicle is not in the vehicle, the reminding information is sent to the mobile phone of the user through the short message information so as to ensure that the user can receive the reminding information.
In one embodiment, as shown in FIG. 2, the parking assist method 200 includes steps S210-S230.
Wherein, step S210 is: and judging whether the current position of the vehicle belongs to a time-limited parking area.
Further, step S210 can be refined to steps S211-S212. Wherein, S211 is: the method includes the steps of obtaining first image data of a traffic sign on the right side of a road of a current position of a vehicle.
The traffic road sign comprises a sign board standing on a road shoulder, and a graphic or an arrow mark drawn on the road or the road shoulder and other marks for indicating traffic regulations.
It can be understood that the time-limited parking area is usually arranged on both sides of the road due to the special effect of the special time period, and based on the arrangement characteristics, whether the current position belongs to the time-limited parking area or not can be judged through the traffic signpost arranged on the right shoulder of the road where the current position of the vehicle is located. And the first image data is intended to cover all traffic signs arranged on the right side of the road where the vehicle is currently located.
It is to be understood that "acquiring the first image data" may be acquiring from a photographing device mounted on the vehicle and capable of photographing the right side of the vehicle. Due to the randomness of the driving position of the vehicle, preferably, the first image data covers a certain range around the driving position of the vehicle to ensure that no traffic signs on the road are missed.
In some embodiments, to ensure that no traffic signs on the road are missed, the image data of the front, back and right of the position of the vehicle can be obtained by a plurality of cameras disposed at a plurality of different positions on the vehicle, and the combination of the image data captured by the plurality of cameras constitutes the first image data.
It is understood that the first image data may also be obtained through a communication module on the vehicle, and the communication module communicates with a roadside unit, a monitoring device or a vehicle networking arranged on a road where the vehicle is located to obtain the first image data stored or captured in the roadside unit, the monitoring device or the vehicle networking.
S212 is: and judging whether the current position belongs to a time-limited parking area or not based on the traffic sign included in the first image data. It can be understood that, when the parking mark of the time-limited parking area exists in the traffic road sign included in the first image data, it may be determined that the current position belongs to the time-limited parking area.
Further, S212 may include steps S2121-S2122.
Step S2121 is: and recognizing the parking mark in the traffic sign included in the first image data by the image. It is understood that the first image data may include a plurality of traffic signs, each of which may exist in different sizes in the first image data, and the image-recognized traffic signs may be all or part of the first image data.
The image recognition is carried out on the first image data to recognize all traffic signs included in the first image data, and the parking marks, such as the signs including the letter "P", in the traffic signs are screened out through a semantic recognition or image comparison method.
The specific image recognition method can be a neural network algorithm, a template matching method, a geometric transformation method and other image recognition methods capable of recognizing the road mark.
Step S2122 is: and responding to the effective time interval on the parking mark, and judging that the current position belongs to a time-limited parking area. And performing digital recognition on part or all of the image data corresponding to the parking identifier to judge whether the parking identifier has an effective time interval, and judging that the current position belongs to a time-limited parking area when the parking identifier has effective time. Meanwhile, the identified effective time interval can be used as a basis for judging whether the vehicle needs to drive away.
Further, step S220 is: and judging whether the vehicle needs to drive away or not in response to the fact that the current position of the vehicle belongs to the time-limited parking area.
It can be understood that when the current position of the vehicle belongs to the time-limited parking area, if the vehicle is in a parking state, whether the current time is close to the stop parking time needs to be judged, and the vehicle needs to drive away before the stop parking time comes; if the vehicle is in the ready-to-park state, whether the current time is close to or exceeds the cut-off parking time needs to be judged, and the vehicle needs to drive away before the cut-off parking time or immediately.
Further, it may be determined whether the vehicle needs to be driven away based on a comparison of the deadline for the valid time interval of the time-limited parking area with the current time.
Specifically, step S220 may include steps S221-S223.
Step S221 is: an end parking time in an active time interval present on the parking mark is identified.
It is understood that step S2122 may be performed simultaneously with step S221 or sequentially. After the time-limited parking mark in the first image data is identified, an effective time range in the time-limited parking mark, such as from time X to time Y, is obtained.
Step S222 is: and judging whether the time interval from the stopping time is smaller than a preset time threshold value.
It is understood that time Y in the validity time interval "time X to time Y" is the cut-off parking time of the time-limited parking area. Further, a time interval between the current time and the cut-off parking time Y is calculated. It will be appreciated that this time interval will at least require more time to drive off the vehicle than the user needs before the end of the parking time. Preferably, the preset time threshold needs to be set according to the driving-away time required by the user, and is used for reserving the user to drive away the vehicle without violating the regulation of the time-limited parking area. For example, if the preset time threshold is set to half an hour, then it can be assumed that the maximum travel-off time required after all users have learned the need for travel-off is half an hour.
Step S223 is: and judging that the vehicle needs to drive away in response to the time interval from the stop time being less than a preset time threshold.
It can be understood that when the time interval between the current time and the cut-off parking time is judged to be smaller than the preset time threshold, the user needs to drive the vehicle away in the time interval, otherwise, violation behaviors exist. The reasonable preset time threshold is the driving-away time reserved for the user, so that the vehicle needs to be driven away as soon as possible when the time interval is smaller than the preset time threshold.
It is understood that the preset time threshold may be set by the manufacturer or may be set individually by the user.
Step S230 is: and generating reminding information to remind a user of driving away as soon as possible in response to the judgment that the vehicle needs to be driven away.
It can be understood that when the vehicle is in a non-flameout state, the reminding information can be displayed through the central control display screen or the instrument display screen so as to be received by the user conveniently. Preferably, in order to prevent the vehicle from being in a parking state and prevent the user from being unable to receive the information when the vehicle is not in the vehicle, the reminding information is sent to the mobile phone of the user through the short message information so as to ensure that the user can receive the reminding information.
In another embodiment, as shown in FIG. 3, the parking assist method 300 includes steps S310-S330.
Wherein, step S310 is: and judging whether the current position of the vehicle belongs to a time-limited parking area.
Further, step S310 may be subdivided into steps S311 to S312.
Wherein, S311 is: the range of all time-limited parking areas of the city where the vehicle is located is obtained.
Specifically, the map data may store information of all time-limited parking areas, and then the related information of the time-limited parking area of the city where the vehicle is located may be obtained from the map data, where the related information at least includes a region range of each parking area.
It is to be understood that the map data may be local map data stored in the vehicle, and the step S311 acquires information of the time-limited parking area therein by reading the map data on the host vehicle. The map data may also be map data stored on the cloud or the internet, and the step S311 obtains the map data from the cloud or the internet through the T-box module on the vehicle.
S312 is: and responding to the condition that the current position belongs to the range of any time-limited parking area, and judging that the current position belongs to the time-limited parking area. It can be understood that, when the current position is within the region range of any one time-limited parking area, the current position belongs to the time-limited parking area, and the effective time interval of the time-limited parking area is the effective time interval in which parking can be performed at the current position.
Further, step S320 is: and judging whether the vehicle needs to drive away or not in response to the fact that the current position of the vehicle belongs to the time-limited parking area.
It can be understood that when the current position of the vehicle belongs to the time-limited parking area, if the vehicle is in a parking state, whether the current time is close to the stop parking time needs to be judged, and the vehicle needs to drive away before the stop parking time comes; if the vehicle is in the ready-to-park state, whether the current time is close to or exceeds the cut-off parking time needs to be judged, and the vehicle needs to drive away before the cut-off parking time or immediately.
Further, it may be determined whether the vehicle needs to be driven away based on a comparison of the deadline for the valid time interval of the time-limited parking area with the current time.
Specifically, step S320 may include steps S321-S323.
Step S321 is: and acquiring the stop parking time of the time-limited parking area to which the current position belongs.
It is to be understood that the step S311 may simultaneously acquire valid time information of all the time-limited parking areas when acquiring range information of all the time-limited parking areas. And judging the time-limited parking area to which the current position belongs, wherein the effective time interval of the time-limited parking area to which the current position belongs is the time interval in which the current position can park.
Alternatively, after the time-limited parking area to which the current position belongs is judged, the effective time interval of the time-limited parking area to which the current position belongs may be further acquired.
Step S322 is: and judging whether the time interval from the stopping time is smaller than a preset time threshold value.
It can be understood that, assuming that the valid time interval obtained in step S321 is from time X to time Y, the time Y therein is the cut-off parking time of the time-limited parking area. Further, a time interval between the current time and the cut-off parking time Y is calculated. It will be appreciated that this time interval will at least require more time to drive off the vehicle than the user needs before the end of the parking time. Preferably, the preset time threshold needs to be set according to the driving-away time required by the user, and is used for reserving the user to drive away the vehicle without violating the regulation of the time-limited parking area. For example, if the preset time threshold is set to half an hour, then it can be assumed that the maximum travel-off time required after all users have learned the need for travel-off is half an hour.
Step S323 is: and judging that the vehicle needs to drive away in response to the time interval from the stop time being less than a preset time threshold.
It can be understood that when the time interval between the current time and the cut-off parking time is judged to be smaller than the preset time threshold, the user needs to drive the vehicle away in the time interval, otherwise, violation behaviors exist. The reasonable preset time threshold is the driving-away time reserved for the user, so that the vehicle needs to be driven away as soon as possible when the time interval is smaller than the preset time threshold.
It is understood that the preset time threshold may be set by the manufacturer or may be set individually by the user.
Step S330 is: and generating reminding information to remind a user of driving away as soon as possible in response to the judgment that the vehicle needs to be driven away.
It can be understood that when the vehicle is in a non-flameout state, the reminding information can be displayed through the central control display screen or the instrument display screen so as to be received by the user conveniently. Preferably, in order to prevent the vehicle from being in a parking state and prevent the user from being unable to receive the information when the vehicle is not in the vehicle, the reminding information is sent to the mobile phone of the user through the short message information so as to ensure that the user can receive the reminding information.
Preferably, as shown in fig. 4, any one of the parking assist methods may further include steps S440 to S460 for determining a penalty incurred after the parking violation at the current position.
Wherein, step S440 is: and acquiring second image data of the road shoulder at the right side of the current position of the vehicle.
It is understood that the first image data may be present or absent according to different implementations of the parking assist method, and is described herein as the second image data, but in different embodiments, the second image data does not imply the presence of the first image data, and even in embodiments where the first image data is present, the first image data and the second image data may refer to the same or different image data.
Step S450 is: and identifying the second image data to judge whether the driving position has a penalty mark.
The existence of specific regulations in traffic regulations may cause corresponding penalty contents if certain marks, such as marks, diagrams, arrows or lines, are violated, and the penalty marks refer to marks, such as marks, diagrams, arrows or lines, which can correspond to specific trigger contents. The penalty mark means that the action of the restriction is a penalty mark for violating the stop.
Specifically, all penalty markers included in the second image data are identified by performing image recognition on the second image data, and further, the penalty markers are identified by matching the penalty markers with templates of the penalty markers.
The specific image recognition method can be a neural network algorithm, a template matching method, a geometric transformation method and other image recognition methods capable of recognizing the road mark.
Step S360 is: and responding to the running position with the penalty mark, and generating the reminding information comprising penalty content.
Specifically, the penalty content may be obtained by matching the penalty mark with the existing traffic regulation regulations. For example, the deduction and/or fine rules corresponding to the road signs in the traffic regulations are matched based on the shape of the line drawn on the road shoulder and the color thereof.
It can be understood that the reminding information including the punishment content can arouse the attention of the user and prevent the gambling psychology.
While, for purposes of simplicity of explanation, the methodologies are shown and described as a series of acts, it is to be understood and appreciated that the methodologies are not limited by the order of acts, as some acts may, in accordance with one or more embodiments, occur in different orders and/or concurrently with other acts from that shown and described herein or not shown and described herein, as would be understood by one skilled in the art.
According to another aspect of the present invention, a parking assistance apparatus is provided for determining whether a current location of a vehicle belongs to a no-parking area so as to assist a user in parking.
In one embodiment, as shown in the hardware schematic block diagram of fig. 5, the secondary parking device 500 includes a memory 510 and a processor 520.
The memory 510 is used to store computer programs.
The processor 520 is coupled to the memory 510 for executing computer programs stored on the memory 510. The processor 520, based on the memory 510, is configured to: judging whether the current position of the vehicle belongs to a time-limited parking area or not; judging whether the vehicle needs to drive away or not in response to the fact that the current position of the vehicle belongs to a time-limited parking area; and generating reminding information to remind a user of driving away as soon as possible in response to the judgment that the vehicle needs to be driven away.
The current position refers to a position where the vehicle is currently located. The present invention is directed to determining whether or not the position of a vehicle in a parking state or a preliminary parking state belongs to a time-limited parking area, and therefore, preferably, the current position of the vehicle includes the parking position of the vehicle in the parking state and the position of the vehicle in which a driver of the vehicle intends to park.
The time-limited parking area refers to an area used as a parking place for some period of time. The time-limited parking area has a corresponding effective time interval, and generally, the corresponding effective time interval may be marked on a mark indicating the parking area.
It can be understood that when the current position of the vehicle belongs to the time-limited parking area, if the vehicle is in a parking state, whether the current time is close to the stop parking time needs to be judged, and the vehicle needs to drive away before the stop parking time comes; if the vehicle is in the ready-to-park state, whether the current time is close to or exceeds the cut-off parking time needs to be judged, and the vehicle needs to drive away before the cut-off parking time or immediately.
Specifically, it may be determined whether the vehicle needs to be driven away based on a comparison of the deadline for the valid time interval of the time-limited parking area and the current time.
Further, when the vehicle is in a non-flameout state, the reminding information can be displayed through the central control display screen or the instrument display screen so as to be received by a user conveniently. Preferably, in order to prevent the vehicle from being in a parking state and prevent the user from being unable to receive the information when the vehicle is not in the vehicle, the reminding information is sent to the mobile phone of the user through the short message information so as to ensure that the user can receive the reminding information.
In a particular embodiment, to determine whether the current location of the vehicle belongs to a time-limited parking area, the processor 520 is further configured to: acquiring first image data of a traffic sign on the right side of a road at the current position of a vehicle; and judging whether the current position belongs to a time-limited parking area or not based on the traffic sign included in the first image data.
The traffic road sign comprises a sign board standing on a road shoulder, and a graphic or an arrow mark drawn on the road or the road shoulder and other marks for indicating traffic regulations.
It can be understood that the time-limited parking area is usually arranged on both sides of the road due to the special effect of the special time period, and based on the arrangement characteristics, whether the current position belongs to the time-limited parking area or not can be judged through the traffic signpost arranged on the right shoulder of the road where the current position of the vehicle is located. And the first image data is intended to cover all traffic signs arranged on the right side of the road where the vehicle is currently located.
It is to be understood that "acquiring the first image data" may be acquiring from a photographing device mounted on the vehicle and capable of photographing the right side of the vehicle. Due to the randomness of the driving position of the vehicle, preferably, the first image data covers a certain range around the driving position of the vehicle to ensure that no traffic signs on the road are missed.
In some embodiments, to ensure that no traffic signs on the road are missed, the image data of the front, back and right of the position of the vehicle can be obtained by a plurality of cameras disposed at a plurality of different positions on the vehicle, and the combination of the image data captured by the plurality of cameras constitutes the first image data.
It is understood that the first image data may also be obtained through a communication module on the vehicle, and the communication module communicates with a roadside unit, a monitoring device or a vehicle networking arranged on a road where the vehicle is located to obtain the first image data stored or captured in the roadside unit, the monitoring device or the vehicle networking.
It can be understood that, when the parking mark of the time-limited parking area exists in the traffic road sign included in the first image data, it may be determined that the current position belongs to the time-limited parking area.
Further, to enable determining whether the current location belongs to a time-limited parking area based on the traffic sign included in the first image data, the processor 520 is further configured to: recognizing a parking mark in a traffic sign included in the first image data by using an image; and responding to the effective time interval on the parking mark, and judging that the current position belongs to a time-limited parking area.
It is understood that the first image data may include a plurality of traffic signs, each of which may exist in different sizes in the first image data, and the image-recognized traffic signs may be all or part of the first image data.
The image recognition is carried out on the first image data to recognize all traffic signs included in the first image data, and the parking marks, such as the signs including the letter "P", in the traffic signs are screened out through a semantic recognition or image comparison method.
The specific image recognition method can be a neural network algorithm, a template matching method, a geometric transformation method and other image recognition methods capable of recognizing the road mark.
And performing digital recognition on part or all of the image data corresponding to the parking identifier to judge whether the parking identifier has an effective time interval, and judging that the current position belongs to a time-limited parking area when the parking identifier has effective time. Meanwhile, the identified effective time interval can be used as a basis for judging whether the vehicle needs to drive away.
Correspondingly, to implement the determination of whether the vehicle needs to drive away based on the first image data to determine whether the current position belongs to the time-limited parking area, the processor 520 is configured to: identifying an end parking time in an effective time interval existing on the parking mark; judging whether the time interval from the stopping time is smaller than a preset time threshold value or not; and judging that the vehicle needs to drive away in response to the time interval from the stop time being less than a preset time threshold.
It is understood that, after the time-limited parking marker in the first image data is identified, the valid time range in the time-limited parking marker is obtained, for example, from time X to time Y.
It is understood that time Y in the validity time interval "time X to time Y" is the cut-off parking time of the time-limited parking area. Further, a time interval between the current time and the cut-off parking time Y is calculated. It will be appreciated that this time interval will at least require more time to drive off the vehicle than the user needs before the end of the parking time. Preferably, the preset time threshold needs to be set according to the driving-away time required by the user, and is used for reserving the user to drive away the vehicle without violating the regulation of the time-limited parking area. For example, if the preset time threshold is set to half an hour, then it can be assumed that the maximum travel-off time required after all users have learned the need for travel-off is half an hour.
Further, when the time interval between the current time and the stop time is judged to be smaller than the preset time threshold, the user needs to drive the vehicle away in the time interval, otherwise, an illegal behavior exists. The reasonable preset time threshold is the driving-away time reserved for the user, so that the vehicle needs to be driven away as soon as possible when the time interval is smaller than the preset time threshold.
Preferably, the preset time threshold may be set by a manufacturer, or may be set individually by a user.
In another particular embodiment, alternatively, to determine whether the current location of the vehicle belongs to a time-limited parking area, the processor 520 may also be configured to: acquiring the ranges of all time-limited parking areas of a city where vehicles are located; and responding to the condition that the current position belongs to the range of any time-limited parking area, and judging that the current position belongs to the time-limited parking area.
Specifically, the map data may store information of all time-limited parking areas, and then the related information of the time-limited parking area of the city where the vehicle is located may be obtained from the map data, where the related information at least includes a region range of each parking area.
It is to be understood that the map data may be local map data stored in the vehicle, and the processor 520 obtains information of the time-limited parking area therein by reading the map data on the host vehicle. The map data may also be map data stored on the cloud or the internet, and the processor 520 obtains the map data from the cloud or the internet through a T-box module on the vehicle.
It can be further understood that, when the current position is within the region range of any one time-limited parking area, the current position belongs to the time-limited parking area, and the effective time interval of the time-limited parking area is the effective time interval in which the current position can be parked.
Correspondingly, to realize the determination of whether the vehicle needs to drive away based on the map data to obtain the relevant information to determine that the current position belongs to the time-limited parking area, the processor 520 may be configured to: acquiring the stop parking time of the time-limited parking area to which the current position belongs; judging whether the time interval from the stopping time is smaller than a preset time threshold value or not; and judging that the vehicle needs to drive away in response to the time interval from the stop time being less than a preset time threshold.
It can be understood that when the range information of all the time-limited parking areas is acquired, the valid time information of all the time-limited parking areas can be acquired simultaneously. And judging the time-limited parking area to which the current position belongs, wherein the effective time interval of the time-limited parking area to which the current position belongs is the time interval in which the current position can park.
Alternatively, after the time-limited parking area to which the current position belongs is judged, the effective time interval of the time-limited parking area to which the current position belongs may be further acquired.
It will be further appreciated that, assuming that the valid time interval obtained by the processor 520 is from time X to time Y, the time Y therein is the cut-off parking time of the time-limited parking area. Further, a time interval between the current time and the cut-off parking time Y is calculated. It will be appreciated that this time interval will at least require more time to drive off the vehicle than the user needs before the end of the parking time. Preferably, the preset time threshold needs to be set according to the driving-away time required by the user, and is used for reserving the user to drive away the vehicle without violating the regulation of the time-limited parking area. For example, if the preset time threshold is set to half an hour, then it can be assumed that the maximum travel-off time required after all users have learned the need for travel-off is half an hour.
When the time interval between the current time and the stop parking time is judged to be smaller than the preset time threshold, the user needs to drive the vehicle away in the time interval, and otherwise, violation behaviors exist. The reasonable preset time threshold is the driving-away time reserved for the user, so that the vehicle needs to be driven away as soon as possible when the time interval is smaller than the preset time threshold.
Preferably, the preset time threshold may be set by a manufacturer, or may be set individually by a user.
Preferably, in any of the above embodiments of the parking assist apparatus, to determine the penalty incurred after the parking violation at the current position, the processor 520 may be further configured to: acquiring second image data of a road shoulder at the right side of the current position of the vehicle; identifying second image data to judge whether the driving position has a penalty mark or not; and responding to the running position with the penalty mark, and generating the reminding information comprising penalty content.
It is understood that the first image data may or may not exist depending on the determination implementation of the time-limited parking area, and thus is described herein as the second image data. However, in various embodiments, the second image data does not imply the existence of the first image data, and even in embodiments where the first image data exists, the first image data and the second image data may refer to the same or different image data.
It will be further understood that the presence of specific regulations in traffic regulations may produce corresponding penalties in response to violations of certain indicia, such as logos, graphics, arrows or lines, that may correspond to specific triggers. The penalty mark means that the action of the restriction is a penalty mark for violating the stop.
Specifically, all penalty markers included in the second image data are identified by performing image recognition on the second image data, and further, the penalty markers are identified by matching the penalty markers with templates of the penalty markers.
The specific image recognition method can be a neural network algorithm, a template matching method, a geometric transformation method and other image recognition methods capable of recognizing the road mark.
The specific penalty content can be obtained by matching the penalty mark with the regulations of the existing traffic laws. For example, the deduction and/or fine rules corresponding to the road signs in the traffic regulations are matched based on the shape of the line drawn on the road shoulder and the color thereof.
It can be understood that the reminding information including the punishment content can arouse the attention of the user and prevent the gambling psychology.
