Detailed Description
In order to make the technical solutions of the present disclosure better understood by those skilled in the art, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only some embodiments of the present disclosure, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the present disclosure may be described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that, in the present disclosure, the embodiments and features of the embodiments may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
According to an embodiment of the present disclosure, there is provided an information processing method for detecting a road surface morphology, as shown in fig. 1, the method including steps 101 to 103 as follows:
step 101: after the transmitting unit transmits deep ultraviolet light to the road surface to be detected for multiple times, the receiving unit receives deep ultraviolet reflected light reflected by the road surface to be detected each time, and converts the deep ultraviolet reflected light received each time into a voltage signal to obtain a measured value set of the voltage signal.
In this embodiment, the emitting unit may be a deep ultraviolet (UVC, wavelength of 200nm to 280nm) emitting circuit; the receiving unit can be a receiving circuit used for receiving the deep ultraviolet emitted light reflected by the road surface to be detected; the transmitting circuit transmits multiple times of deep ultraviolet light to a road surface to be detected, the receiving unit receives deep ultraviolet reflected light after each time of deep ultraviolet light is transmitted by the road surface to be detected, the received deep ultraviolet reflected light is converted into a voltage signal, the size of the voltage signal is in direct proportion to the intensity of the light of the deep ultraviolet reflected light, and after the multiple times of deep ultraviolet transmitted light is subjected to signal conversion, a measurement value set of the voltage signal can be obtained.
Because the wavelength of deep ultraviolet light (UVC) is 200nm-280nm, sunlight in this wave band is absorbed by an ozone layer when entering the atmosphere, so that the road surface to be detected has no UVC, and does not have UVC in road light and vehicle light, therefore, in the road surface light environment, the background noise of the UVC wave band is relatively pure, so the embodiment detects the road surface based on the deep ultraviolet reflected light, can avoid light interference, and improve the detection precision of the road surface state.
Step 102: and determining different preset voltage ranges which are corresponding to different road surface forms and are limited by the maximum voltage threshold and the minimum voltage threshold.
In this embodiment, the road surface morphology may include an icy road surface, a snow road surface, a water accumulation road surface, an asphalt road surface, and the like, and the voltage threshold determined based on the deep ultraviolet light may be predetermined for different road surface morphologies. For example, for an icy road, deep ultraviolet light may be emitted to the icy road 1, the icy road 2, on the icy road n in advance by using the emission unit for multiple times, and the deep ultraviolet emission light signal reflected by each icy road is converted into a voltage signal, so that a voltage signal measurement value set corresponding to each icy road may be determined, for example, the voltage signal measurement value corresponding to the icy road 1, the icy road 2, the deep ultraviolet emission light signal corresponding to the icy road n is 2.5 to 5.1, 1.3 to 4.4, the deep ultraviolet emission light signal corresponding to the icy road n is 2.6 to 5.5, and then the minimum threshold value and the maximum threshold value of the preset voltage range may be determined based on the minimum threshold value and the maximum threshold value in each set. For example, the maximum threshold value at which the value on each ice road surface is the largest may be determined as the maximum threshold value of the preset voltage range, e.g., if 5.5 is the largest value among the maximum threshold values on a large number of ice roads, 5.5 may be determined as the maximum voltage threshold value of the preset voltage range. Similarly, the minimum threshold with the smallest value on each ice road surface may also be determined as the minimum threshold of the preset voltage range, for example, if 1.3 is the minimum threshold on a large number of ice road surfaces, then 1.3 may be determined as the minimum threshold of the preset voltage range, and then the preset voltage range is (1.3-5.5). It is to be understood that the above values are exemplary, and the values in the actual scene differ depending on the road surface environment.
The minimum threshold and the maximum threshold of the preset voltage range may also be determined based on the average of the minimum threshold and the maximum threshold in each set, for example, (2.5+1.3+ ·+2.6)/n is used as the minimum threshold of the preset voltage; the maximum threshold value of the preset voltage is (5.1+4.4+. 5.5)/n, and then the preset voltage range can be (1.8-5.3).
It will be appreciated that for different waysSurface morphology, asphalt, cement, ice, snow, water accumulation, etc., from a maximum threshold VHAnd VLThe ranges defined are not identical and may overlap partially, but not completely.
Step 103: and judging different times that the measured values of the voltage signals in the voltage signal set fall into different preset voltage ranges, and determining the road surface form of the road surface to be detected based on the different times.
In this embodiment, after the road surface to be detected emits the deep ultraviolet light each time, the deep ultraviolet reflected light is subjected to signal conversion, and the corresponding preset voltage range of which road surface form the converted voltage falls into is determined, so that the number of times of falling into each road surface form after M times of detection can be determined, and the road surface form with the largest number of times of falling into is determined as the road surface form of the road surface to be detected. For example, the road surface to be detected is subjected to deep ultraviolet detection for 100 times, voltage conversion is performed on each time of deep ultraviolet emitted light, if the voltage conversion is performed to 4.8V, 4.5V, 4.3V, the right-to-say, 5.0V, the 1 st measured value 4.8V falls into the preset range corresponding to the frozen road surface, the 2 nd measured value 4.3V falls into the preset range corresponding to the frozen road surface and the preset range corresponding to the ponding road surface, the 100 th measured value 5.0V falls into the preset range corresponding to the asphalt road surface and the preset range corresponding to the ponding road surface, and if the number of times of falling into the frozen road surface is the largest in the 100 measured values, the road surface shape of the road surface to be detected is the frozen road surface.
This embodiment is through waiting to survey road surface transmission deep ultraviolet light, and will wait to survey the deep ultraviolet reverberation conversion of road surface transmission and be voltage signal, the form on road surface is waited to survey based on voltage signal determination, because utilize the deep ultraviolet light of background noise relative pureness to survey the road surface form, and carry out analysis processes to the reverberation, can distinguish the form on current road surface, the icy road sensor based on infrared laser has been avoided, receive the interference of background light noise easily in outdoor application environment, and then improved the detection precision, the detection cost is reduced.
As an optional implementation manner of this embodiment, after converting the deep ultraviolet emitted light received each time into a voltage signal and obtaining a measurement value set of the voltage signal, the method further includes: determining a voltage correction value under the visibility measured value based on the received visibility measured value of the surrounding environment of the road surface; after converting the deep ultraviolet emitted light received each time into a voltage signal, determining a voltage correction measurement value based on the voltage signal and the voltage correction value, and obtaining a correction measurement value set of the voltage signal.
In this alternative implementation, since the propagation of the UVC may be affected by atmospheric visibility, the voltage signal of the converted deep ultraviolet reflected light may be corrected and compensated to make the detection accuracy higher.
After receiving the visibility measured value of the surrounding environment of the road surface, the voltage correction value Δ V under the visibility measured value may be determined, and the low visibility may make the voltage value V0 corresponding to the deep ultraviolet reflected light smaller than the actual value V1, and after converting each received deep ultraviolet emitted light into a voltage signal, the voltage correction measured value V1 is determined to be V0+ Δ V based on the voltage signal and the voltage correction value, and after multiple detections, the correction measured value set of the voltage signal may be obtained. .
The process of determining the voltage correction value may include: the method comprises the steps of firstly determining an actual visibility grade corresponding to a visibility measurement value, and then determining a voltage correction value corresponding to the actual visibility grade based on voltage correction values corresponding to different grades.
As an optional implementation manner of this embodiment, voltage correction values corresponding to different visibility levels are determined; determining the visibility grade corresponding to the visibility measurement value; and determining a voltage correction value corresponding to the visibility grade.
In this optional implementation, the purpose of correcting the compensation voltage signal is to enable the voltage signal converted from the reflected deep ultraviolet light to approach the voltage signal converted from the deep ultraviolet light reflected by the road surface when the visibility is high.
Specifically, when voltage correction values corresponding to different visibility levels are determined, reference voltage signals corresponding to reflected deep ultraviolet light of a road surface can be determined when the visibility level is highest (the higher the visibility level is, the better the visibility is, and the smaller the attenuation of the reflected deep ultraviolet light is); then, under different visibility, determining a voltage correction value based on a voltage signal corresponding to deep ultraviolet light emitted by a road surface, for example, when the visibility is highest level III (100-150), a reference voltage signal is 5.5V; when the visibility is level II (the measured value of the visibility is 50-100), the voltage signal corresponding to the deep ultraviolet light reflected by the road surface is 4.5V, and then the corrected value of the voltage can be 0-1. Likewise, in this way, voltage correction values corresponding to different visibility levels can be determined separately.
As an optional implementation manner of this embodiment, the method further includes: if the determined road surface form of the road surface to be detected is various, receiving the road surface temperature measured by the temperature measuring unit; and determining one road surface form in a plurality of forms of the road surface to be detected based on the road surface temperature.
In the optional implementation manner, the road surface form of the road surface to be detected determined based on different times may include two road surface forms at the same time, and for the situation, the form of the road surface can be judged by using temperature assistance, so that the result is more accurate, and the defects of inaccurate road surface form determination and high cost by using a temperature measurement sensor are overcome.
Specifically, if the determined road surface morphology of the road surface to be detected is in a plurality of morphologies, the road surface temperature measured by the temperature measurement unit is received, and the final road surface morphology is determined based on the road surface temperature. For example, if the determined form of the road surface to be detected is an icy road surface and a ponded road surface, the road surface form may be determined to be an icy road surface if the temperature of the road surface to be detected measured at this time is lower than 0 ℃. The correspondence between the temperature and the road surface form may be set and stored in advance.
From the above description, it can be seen that the present disclosure achieves the following technical effects: the detection of the road surface form can be more accurate, the power consumption is reduced, and the cost is reduced.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
