Detailed Description

The present application is described in further detail below with reference to the attached drawings.

In order to facilitate the recognition of a vehicle license plate in the driving process of a vehicle, the embodiment of the application discloses an LED adaptive control method, a system and a readable storage medium, with reference to fig. 1 and 9, including:

and S110, setting the illumination intensity of the LED and the illumination range of the road surface based on the ambient brightness.

The environment brightness is different in different time periods and different weather, for example, when the environment brightness is different in the daytime and the environment brightness is different in the nighttime, the environment brightness is different in the cloudy time period and the environment brightness is different in the sunny time period, and when the environment brightness is low, light is supplemented through an LED. Meanwhile, the LEDs also need to be set based on the illumination range of the road surface, for example, when the illumination range of the road surface is large, if the number of the LEDs is small, the illumination range is large, the illumination effect is poor, and therefore, a corresponding number of LEDs need to be set for the illumination range of the road surface for supplementary lighting. Simultaneously, in this application embodiment, LED shines angle, luminance to and the distance of the lens of setting and LED lamp pearl body all can correspond and adjust, so that carry out adaptive control to LED.

And S120, controlling the LED to irradiate the road surface based on the illumination intensity and the irradiation range, and detecting whether the license plate reflects light.

The number plate is also referred to as a vehicle number plate, and is a plate suspended at the front and rear of the vehicle, and is usually made of aluminum, iron sheet, plastic, paper, or the like, and a registration number, a registration area, or other relevant information of the vehicle is engraved on the number plate. The region of the vehicle can be known through the license plate, and the owner of the vehicle and the registration information of the vehicle can be checked according to the license plate. The license plate does not reflect light under direct sunlight and reflects light under direct light, so that the LED is controlled to irradiate the whole road surface based on the illumination intensity and the irradiation range, and whether the vehicle exists or not is identified by detecting whether the license plate reflects light or not. In this embodiment, since the vehicle lamp is correspondingly turned on if the ambient light is dark during the driving process of the vehicle, the light of the vehicle lamp and the reflected light of the license plate need to be distinguished.

S130, when the detection result is yes, positioning the license plate based on the reflection light, and acquiring the real-time moving speed of the license plate.

The shape of the license plate is different from the shapes of luminous bodies such as vehicle lamps and the like, and the natural installation position of the license plate is different from the positions of the vehicle lamps and the like, so that the license plate can be positioned based on the shape and the position of the license plate, the real-time moving speed of the license plate is obtained, and the moving speed of the license plate is the same as the moving speed of the vehicle. Before license plate recognition is carried out through the LED, the LED is controlled to enlarge the light-emitting range, namely, the luminous flux of the LED in the range of the road surface is increased, so that all lanes on the road surface are covered. In this embodiment, when detecting whether there is light reflection of the license plate, if the detection result is negative, the detection is continuously maintained until the detection result is positive, and the license plate is repeatedly positioned to obtain the real-time moving speed of the license plate.

S140, self-adaptive control is carried out on the LED based on the real-time moving speed of the license plate, so that the LED continuously illuminates the license plate until the license plate is identified.

The embodiment of the application detects the normal running process of an automobile, for example, the illumination measures of road sections existing in an expressway are poor, when the track of the automobile needs to be acquired, the license plate is located at a position close to the lower end of the automobile, and the license plate is inconvenient to recognize due to the illumination of automobile lamps. The self-adaptive control means that the illumination direction of the LED is positioned, so that the illumination of the LED can move along with the movement of the license plate, and the license plate can be continuously illuminated as far as possible when the vehicle runs to a recognition area, so that the license plate can be recognized in the running process of the vehicle.

The implementation principle of the LED self-adaptive control method in the embodiment of the application is as follows: when a vehicle runs on a road surface, the illumination intensity of the LED and the irradiation range of the LED to the road surface are set based on the ambient brightness, so that the illumination of the LED is increased, the irradiation range of the LED to the road surface is increased in a targeted manner, when the movement of a license plate is detected, the LED is subjected to self-adaptive control, when the vehicle runs on the road section, when the ambient illumination is weak, the LED can continuously illuminate the license plate along with the movement of the vehicle, and the license plate can be conveniently identified in the running process of the vehicle.

Because illumination environment can change along with the sheltering from of barrier, for the messenger to ambient brightness's measurement more accurate, refer to fig. 2, set up LED's illumination intensity and the irradiation range to the road surface based on ambient brightness, include:

s210, detecting the ambient brightness through a plurality of ambient light sensors to obtain the ambient brightness corresponding to a plurality of LEDs, and obtaining the average ambient brightness based on a plurality of ambient brightness.

Wherein, a plurality of ambient light sensor through setting up detect the environment continuous reading, acquire average ambient brightness based on a plurality of ambient brightness, when one of them ambient light sensor receives the sheltering object that flies to shelter from like leaf, plastic bag etc. when, the ambient brightness that this ambient light sensor detected is great than other ambient light sensor fluctuation range, then does not adopt the ambient brightness that this ambient light sensor gathered to report an emergency and ask for help or increased vigilance the operation, in order to warn this ambient light sensor by sheltering from or breaking down. For example, in this embodiment, three ambient light sensors facing different angles may be adopted, and the light sensing devices of the three ambient light sensors are not directly irradiated by sunlight, and the sensed light corresponding to the ambient brightness is reflected light in the environment, so as to increase the measurement accuracy.

And S220, setting the irradiation range of the LED to the road surface based on the average ambient brightness.

Wherein, when the average ambient brightness is larger, the range of light supplement by the LED is smaller, therefore, a larger irradiation range can be set for overall light supplement to the road surface, when the average ambient brightness is smaller, if the form of whole light filling is adopted, because the quantity of LED is comparatively limited, consequently for make LED's setting comparatively reasonable, need shine to the lane of difference on the road surface to increase irradiation efficiency.

And S230, setting the illumination intensity of the LED based on the average ambient brightness.

Similarly, when average ambient brightness is smaller, the degree that the correspondence needs to carry out the light filling through LED is bigger to make the discernment to the license plate clearer, when average ambient brightness is bigger, the degree that the correspondence needs to carry out the light filling through LED is smaller.

Referring to fig. 3 and fig. 9, in order to further illustrate the influence of the average ambient brightness on the irradiation range of the LED on the road surface, in this embodiment, the setting of the irradiation range of the LED on the road surface based on the average ambient brightness includes:

and S310, acquiring the number of lanes on the current road surface and dividing each lane.

In the embodiment, the lanes of the road surface are divided by identifying the traffic markings on the road surface, and since the color of the traffic markings is different from the colors of other positions of the road surface, the lanes of the road surface are divided by the traffic markings, so that the range and the number of the corresponding lanes are distinguished. For example, when a traffic marking dividing lanes exists in a certain identified road, the road can be considered as a dual lane.

And S320, setting the irradiation range of the LED to the road surface based on the divided lanes and the number of traffic flows.

In this embodiment, when the number of lanes is large, the corresponding illumination ranges are respectively set for the lanes, so as to avoid as much as possible the phenomenon that the LEDs are not illuminated timely when the number of lanes is large, for example, when the number of lanes is four, if the number of LED light sources is set to one, if there are a plurality of vehicles running side by side at the same time, when license plates are recognized, the illumination of one LED light source to the plurality of license plates may be too late for illumination, and thus the corresponding LEDs are set for the corresponding lanes, so as to illuminate each license plate respectively when license plate recognition is performed. In other embodiments, the lane dividing method can also divide the lanes according to the traffic flow, because the vehicles on different lanes go to different directions, such as a turning lane, a straight lane and the like, and because different lanes go to different positions, for example, when a lane is in a peak period of getting on or off duty, the number of the vehicles on the straight lane is large, the number of the vehicles on the turning lane is small, and when the lane is in a working time, the number of the vehicles on the turning lane is large, and the number of the vehicles on the straight lane is small. Therefore, the irradiation range of the LEDs on the road surface needs to be set according to the traffic flow number of the corresponding lane, if the vehicle is in a working peak, the number of the LEDs for supplementing light to the straight lane with a large number of vehicles is set to be plural, such as two or three, and the number of the LEDs for supplementing light to the turning-around lane with a small number of vehicles is set to be one, and the setting is performed according to the actual traffic flow.

Referring to fig. 4, irradiating the road surface based on the illumination intensity and the irradiation range, and detecting whether there is reflection of the license plate, includes:

s410, the road surface is irradiated based on the illumination intensity and the irradiation range, and whether the glitter different from the brightness of the surrounding environment exists in the current irradiation environment or not is detected.

And S420, identifying the shape of the glittering body to judge whether the glittering body is the light reflection of the license plate.

In the embodiment, in the case that the judgment and recognition are performed in a case where the ambient illumination is weak, for example, at night, in the early morning or in the evening, when it is detected whether there is a flash body having a brightness different from that of the surrounding environment in the current illumination environment to detect whether there is a vehicle running, when the license plate of the vehicle is illuminated, the reflection may occur by removing the license plate, and when the ambient brightness of the road surface is low, the vehicle lamp of the vehicle may be turned on, so that the illumination of the vehicle lamp and the reflection of the license plate need to be distinguished. In this embodiment, the flash body is subjected to shape recognition to determine whether the flash body is a light reflection of a license plate, and the flash body can be subjected to shape recognition to determine whether the flash body is a license plate. The shape of the license plate needs to be carried out according to the national standard, and whether the license plate is judged by identifying the shape of the glittering body.

After the luminous body is identified as the license plate, because the license plate moves in real time along with the vehicle, in order to illuminate the license plate, the license plate is convenient to identify, the position of the license plate needs to be acquired in real time, and referring to fig. 5, the license plate moving speed and the real-time position of the license plate are acquired, which comprises the following steps:

S530, acquiring the real-time position of the license plate based on the first distance and the real-time distance.

And S540, acquiring the real-time moving speed of the license plate based on the vehicle running time and the real-time position of the license plate.

According to the national traffic regulation, the size of a license plate of a vehicle with the same specification is constant, the license plate is positioned to obtain the real-time area of the license plate, namely the real-time area of the license plate on a coordinate system, for example, when the size of the area of a license plate body of a certain vehicle is 480mm 140mm, the first area of the license plate shot at the first time in a view-finding frame is 24mm 7mm, the area of the license plate in the view-finding frame is continuously measured for a period of time to obtain the area conversion of the license plate, the real-time moving distance of the license plate is calculated according to the area conversion of the license plate in unit time, and the real-time moving speed of the license plate is calculated and obtained on the basis of the real-time moving distance and the moving time. In this embodiment, the real-time moving speed of the license plate is calculated without integrating other light sources such as the car light, so in other embodiments, the real-time moving speed can be calculated by considering the integration factors of the car light and the license plate, for example, a triangle is defined between the car light and the license plate, and the real-time area transformation of the triangle is calculated.

Referring to fig. 6 and 9, after the real-time moving speed of the license plate is obtained, the license plate needs to be illuminated in a following manner according to the moving speed of the license plate, so that the license plate can be identified conveniently.
