Description
Technical Field
The invention relates to the field of balance car control, in particular to a cruise law enforcement method and device for a balance car.
Background
Various road surface violations are important reasons for causing traffic jam, but because urban roads are numerous, traffic polices cannot be dispatched to each road section to perform law enforcement for 24 hours, so that the existing police force arrangement can only achieve small-scale random spot check, the law enforcement is weak, most drivers still have good luck psychology, and the effect of managing violations is not obvious.
Disclosure of Invention
The invention aims to provide a balance car cruise law enforcement method and device for improving the effect of illegal parking management.
The purpose of the invention is realized by the following technical scheme:
according to one aspect of the invention, the invention discloses a balance car cruise enforcement method, which comprises the following steps:
entering a law enforcement state according to the position information and the time; starting self-balancing;
searching for a violation vehicle in a static state;
shooting the license plate number of the violation vehicle;
and printing a penalty ticket and sending penalty information to a corresponding vehicle owner.
Further, the method for searching for the violation vehicle in the static state comprises the following steps:
acquiring an image of a main driving position;
carrying out face recognition processing;
if the person in the main cab is not found, the vehicle is judged to be a violation vehicle.
Through the face recognition technology, the accuracy of judgment can be improved, and large-scale error penalty is avoided. In addition, the technical scheme does not need to identify specific people, only needs to determine the people in the vehicle, is relatively simple, and can improve the judgment accuracy in a low-cost mode.
Further, the method for searching for the violation vehicle in the static state comprises the following steps:
acquiring a thermodynamic diagram of a vehicle;
and comparing the difference between the engine and the carriage area and other areas to judge whether the vehicle breaks rules or not.
Humans are warm-blooded animals whose imaging of thermodynamic diagrams is of significant nature and stability. Therefore, the amount of calculation of image processing can be significantly reduced by the judgment through the thermodynamic diagram, and the implementation cost can be reduced. In addition, even if some windows are pulled, the situation that the window cannot be judged by a conventional shooting means can be met by the thermodynamic diagram, and the application range is wider.
Further, the method for printing the penalty ticket and sending the penalty information to the corresponding vehicle owner comprises the following steps:
sending the license plate number to a cloud server;
the cloud server inquires a registered vehicle owner according to the license plate number;
and sending the punishment information to the vehicle owner in a short message, mail or WeChat mode.
Further, the method for entering the law enforcement state according to the position information and the time comprises the following steps:
starting self-balancing after entering a law enforcement state;
and automatically driving according to a preset route.
Further, the method for searching the violation vehicle in the static state comprises the following steps:
judging the motion state of the front object;
when the front object is in a static state, shooting a picture of the front object, and comparing the picture with a vehicle picture library stored in a cloud end;
if the comparison result judges that the current object is a vehicle, acquiring an image of the main driving position;
carrying out face recognition processing;
if the person in the main cab is not found, the vehicle is judged to be a violation vehicle.
Further, the object characteristics include character information, height information, and width information;
when the character information is rigid and the height exceeds a first threshold value, planning a detour route according to the width information; or the character information is flexible, the height exceeds a second threshold value, and a detour route is planned according to the width information; the second threshold is greater than the first threshold;
and when the character information is flexible and the height is less than or equal to a second threshold value, controlling the balance car to cross from the top of the object in front.
Further, the method for searching the violation vehicle in the static state comprises the following steps:
judging the motion state of the front object;
when the front object is in a static state, shooting a picture of the front object, and identifying whether a license plate number exists in the picture;
if the license plate number exists, judging that the current object is a vehicle, and then acquiring an image of a main driving position to perform face recognition processing; if the person in the main cab is not found, the vehicle is judged to be a violation vehicle.
Further, the method for judging the motion state of the front object comprises the following steps:
shooting pictures of a front object at preset time intervals;
comparing the positions of the front objects in any two pictures, and if the positions are the same, judging that the front objects are static; otherwise, the movement is judged.
According to another aspect of the invention, the invention discloses a balance car cruise enforcement device, which comprises:
means for entering a law enforcement state based on the location information and time;
means for initiating self-balancing;
means for locating a violation vehicle at a standstill;
means for photographing a license plate number of the violation vehicle;
and a device for printing the penalty ticket and sending the penalty information to the corresponding vehicle owner.
Compared with the prior art, the invention has the technical effects that: the invention carries out law enforcement on road surface violation through the balance car. The balance car has low cost and small volume, and can be completely used in a large scale. The balance car can realize automatic driving in an unmanned state by utilizing a no-load balance technology created by the inventor, can enter a road section which is not allowed to violate a law to patrol and enforce the law through remote positioning control in a time period which is not allowed to violate the law, can realize large-scale and high-density elimination, greatly reduces the luck psychology of drivers, and obviously reduces the violation phenomenon.
