[0024] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.
[0025] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.
[0026] Next, in conjunction with the accompanying drawings, the information collection provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.
[0027] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of an information collection method provided by an embodiment of the present application.
[0028] As Figure 1 shown, the information collection method includes the following steps:
[0029] Step 101, at at least one sampling moment, obtain the detection value of each pressure sensing detection unit in the pressure sensing detection unit array, the pressure sensing detection unit array is disposed in the target area, and the detection value is associated with the pressure value.
[0030] If the area for traffic flow statistics is a closed or semi-closed area, such as a scenic area, a shopping mall, a station, etc., the target area can be located at the entrance and exit of the above-mentioned closed or semi-closed area, such as the entrance and exit of a parking lot. If the area for traffic flow statistics is a road, such as a highway, an urban arterial road, etc., the target area can be set according to the position where traffic flow statistics are actually required. Exemplarily, the target area can be located at any position on a main section of a certain highway, or can be an entrance and exit of a certain highway, such as a highway toll station or a highway interchange hub, etc., which can be determined according to the actual situation and will not be specifically limited here.
[0031] The pressure sensing detection unit array includes a plurality of pressure sensing detection units, and the plurality of pressure sensing detection units can be set as a rectangular array, a circular array or other pattern arrays according to actual needs. The pressure sensing detection unit array can be directly disposed on the ground of the target area, or can be carried by a pressure sensing panel or a carpet and then disposed on the ground of the target area. Specifically, it can be determined according to the actual situation and is not specifically limited herein.
[0032] The at least one sampling moment can be determined in advance, and can be a directly determined sampling moment, such as 08:00:00, 08:00:01, 08:00:02 ···, or can be a sampling moment determined according to a preset sampling start moment and a sampling time interval. For example, the sampling start moment is 08:00:00 and the sampling time interval is 1 / 70 second, or 70 times are collected per second.
[0033] In specific implementation, when the vehicle is traveling on the target area, its tires will contact at least one pressure sensing detection unit in the pressure sensing detection array. Based on the weight of the vehicle, the vehicle will apply pressure to the pressure sensing detection unit contacted by the tire, and the pressed pressure sensing detection unit can detect a detection value related to the pressure value. The detection value can be a pressure value. Exemplarily, when the pressure sensing detection unit is a pressure sensor, the detection value is a pressure value. The detection value can be other numerical values linearly related to the pressure value, such as a capacitance value, a resistance value, etc. Exemplarily, when the pressure sensing detection unit is a piezoresistive detection unit, the detection value is a resistance value. In specific implementation, the linear relationship between the resistance value and the pressure value can be determined based on the detection principle of piezoresistive detection. If necessary, the resistance value can also be converted into a pressure value.
[0034] Step 102: Determine the pressure sensing information of the target area according to the detection value.
[0035] Since the detection value is generated based on the pressure applied by the vehicle to the target area, the pressure sensing information determined according to the detection value can reflect the sensing situation of the target area for the traveling vehicle.
[0036] The pressure sensing information can include the associated information of the detection value, such as the magnitude of the detection value, the detection time of the detection value, etc. The pressure sensing information can also include the associated information of the pressure sensing detection unit corresponding to the detection value, such as the identification information of the pressure sensing detection unit, the position information of the pressure sensing detection unit in the pressure sensing detection array, etc. The pressure sensing information can also include the information associated with both the detection value and the pressure sensing detection unit.
[0037] The pressure sensing information may be in the form of data. Exemplarily, it may be a detection value in numerical form, the position of a pressure sensing detection unit in coordinate form, the identifier of a pressure sensing detection unit in character form, etc. The pressure sensing information may also be in the form of an image. Exemplarily, based on the shape and boundary of the target area, the shape and boundary of a pressure sensing image are correspondingly formed, and then the color is used to distinguish the pressure sensing detection units that are pressed and those that are not, or the color depth is used to represent the magnitude of the detection value, etc.
[0038] It can be understood that the implementation manner of the pressure sensing information is not limited to this, and it can be determined according to the actual situation specifically, and no specific limitation is made here.
[0039] Step 103: Analyze the pressure sensing information to obtain the target information of the target area, where the target information includes traffic flow information.
[0040] In specific implementation, optionally, by analyzing the pressure sensing information, information such as the driving path or tire marks of a vehicle in the target area can be obtained, and then the traffic flow information in the target area can be determined based on this information. It should be noted that the target information may also include other information of the target area. Optionally, the target information may also include other information associated with the vehicles driving in the target area, such as driving direction, driving speed, load, etc., and no specific limitation is made here.
[0041] In the embodiment of the present application, through a pressure sensing detection array provided on the ground, the pressure senses the vehicles passing through the target area, and the associated information of the vehicles passing through the target area can be obtained more accurately and completely. Compared with the related art where traffic flow information is collected by a camera installed at a high place, problems such as vehicle occlusion or misdetection due to sunlight can be avoided, and the accuracy of traffic flow statistics is improved.
[0042] Optionally, step 102 includes:
[0043] According to the detection value obtained at the first sampling moment and the position of each pressure sensing detection unit in the pressure sensing detection unit array, determine the pressure sensing image of the target area at the first sampling moment, where the first sampling moment is any sampling moment among the at least one sampling moment;
[0044] Based on the pressure sensing images of the target area at each sampling moment, generate a pressure sensing image sequence of the target area, where the pressure sensing information includes the pressure sensing image sequence.
[0045] In this embodiment, at each sampling moment, the detection value of each pressure sensing detection unit can be obtained, and the detection value is associated with the position of the pressure sensing detection unit in the pressure sensing detection array. In this way, based on the above two pieces of information, a pressure sensing image can be drawn at each sampling moment. The pressure sensing image includes the current sampling moment, and the pressure sensing footprint corresponding to the tire of the vehicle in the target area can be regarded as an "image frame" containing the vehicle tire footprint collected at the current sampling moment.
[0046] Exemplarily, at the first sampling moment, the tire of the vehicle traveling in the target area contacts the target area, and pressure can be applied to the pressure sensing detection units corresponding to the contact area. The pressurized pressure sensing detection units can obtain the current detection value. Since the contact areas between the vehicle tire and the pressure sensing detection units at different positions are different, the detection values obtained by the pressure sensing detection units at different positions are different. After obtaining the detection value corresponding to the first sampling moment, based on the arrangement of the pressure sensing detection units in the pressure sensing detection array, black dots are drawn at the positions of the pressurized pressure sensing detection units, and the gray levels of the black dots are determined according to the magnitudes of the detection values. White dots are drawn at the positions of the non-pressurized pressure sensing detection units. In this way, a pressure sensing image can be drawn, and a schematic diagram of the pressure sensing image can be as Figures 2a to 2d shown.
[0047] Based on the pressure sensing images of the target area at each sampling moment, the above-mentioned multiple pressure sensing images can be arranged in time sequence to obtain a pressure sensing image sequence, which can be regarded as a "video picture" containing the vehicle tire footprint collected at a continuous plurality of sampling moments. Exemplarily, as Figures 2a to 2d shown, the pressure sensing images corresponding to four sampling moments of 08:00:00, 08:00:01, 08:00:02, and 08:00:03 are respectively. As the vehicle in the target area moves, the positions of the tire footprints in the pressure sensing image corresponding to each sampling moment are different. Combining these four pressure sensing images can form a video picture containing four image frames, so that information such as the number of vehicles in the target area, the moving trajectories of each vehicle, and the moving directions can be analyzed.
[0048] In an alternative embodiment, step 103 includes:
[0049] Identify the tire footprints in the pressure sensing image sequence and obtain the footprint features of each tire footprint;
[0050] Based on the footprint features of the tire footprints, determine the tire footprints of the same vehicle as the tire footprints of the same vehicle;
[0051] According to the number of tire footprints in the pressure sensing image sequence and the corresponding relationship between each tire footprint and the vehicle, determine the traffic flow information of the target area.
[0052] In specific implementation, image and video processing technologies in related technologies can be used to identify the tire imprints in the pressure-sensitive image sequence, such as OpenCV, etc. By using such open-source image processing software and customizing the parameters and templates of image processing based on the contour features or texture features of the tire imprints before processing, the tire imprints in the pressure-sensitive image sequence can be identified, and then the imprint features of each tire imprint can be extracted. It should be noted that the specific implementation manners of processing the pressure-sensitive image and the pressure-sensitive image sequence can refer to the descriptions in related technologies and will not be elaborated here.
[0053] Based on the imprint features of the tire, it can be determined whether there are the same tire imprints in the current time period, and these same tire imprints can be regarded as the tire imprints of the same vehicle.
[0054] Optionally, the imprint features include at least one of an imprint orientation, an imprint motion time sequence, an imprint texture feature, an imprint size feature, and an imprint pressure feature. The imprint orientation can represent the driving direction of the tire, and the imprint orientations corresponding to the tires of the same vehicle are usually the same or similar. The imprint motion time sequence can represent the driving direction of the tire and the time sequence of the contact between the tire and the pressure-sensitive detection unit on the target area, and the imprint motion time sequences corresponding to the tires of the same vehicle are usually the same. The imprint texture feature can represent the relevant information of the tire tread, pattern, lines, etc. The tire tread, pattern, lines, etc. can represent the type of the tire, the wear condition of the tire, etc. According to the type of the tire, the vehicle model can be further determined. According to the wear condition of the tire, different vehicles with different usage conditions can be further distinguished among vehicles of the same model, or the front wheels or rear wheels of the vehicle can also be distinguished, etc., to assist in determining whether they are the tire imprints corresponding to the same vehicle. The imprint size feature can represent information such as the width of the tire imprint and whether it is a dual tire, so as to further determine the vehicle model, etc. The imprint pressure feature can represent the pressure application information of the tire imprint, so as to further determine the load information of the vehicle, to assist in determining whether they are the tire imprints corresponding to the same vehicle.
[0055] In specific implementation, in an optional implementation manner, the imprint features include imprint orientation, imprint movement timing sequence, imprint texture features, imprint size features, and imprint pressure features. Different tire imprints in different driving directions can be distinguished according to the imprint orientation and imprint movement timing sequence. Then, for tire imprints in the same driving direction, it can be further determined whether there are the same tire imprints. Exemplarily, in one way, for tire imprints in the same driving direction, the imprint texture features of any two tire imprints can be compared first, and multiple tire imprints with matching imprint texture features can be classified into the same category; then, further classification can be made according to the imprint size features of each category of tire imprints. In another way, for tire imprints in the same driving direction, the imprint size features of any two tire imprints can be compared first, and multiple tire imprints with matching imprint size features can be classified into the same category; then, further classification can be made according to the imprint texture features of each category of tire imprints. Finally, the classification is further verified and refined according to the imprint pressure features to obtain the final classification result of the tire imprints, and the tire imprints classified into the same category are determined to be the tire imprints of the same vehicle.
[0056] According to the above classification result of the tire imprints, the number of vehicles driving on the target area can be determined, and thus the traffic flow information in the target area can be obtained. Exemplarily, for a four-wheel motor vehicle, if the same four tire imprints are identified in the same pressure-sensitive image, they may be the tire imprints corresponding to the four tires of the same vehicle. When counting the traffic flow information subsequently, these four tire imprints are counted as one vehicle or one vehicle trip. Further, if the same multiple tire imprints are identified in the pressure-sensitive images corresponding to multiple sampling moments in a sampling period, it can be determined whether they are of the same vehicle by combining the orientation of the tire imprints and the spacing between the tire imprints, so as to avoid double counting or omission.
[0057] In an optional implementation manner, before determining the same tire imprints as the tire imprints of the same vehicle based on the imprint features of the tire imprints, the method further includes:
[0058] Obtain the target tire imprints within a preset time period in the pressure-sensitive image sequence;
[0059] Determining the same tire imprints as the tire imprints of the same vehicle based on the imprint features of the tire imprints includes:
[0060] Based on the imprint features of the target tire imprints, determine the same target tire imprints as the tire imprints of the same vehicle.
[0061] The difference between this embodiment and the above - mentioned embodiment is that the traffic volume in the target area is separately counted in different time periods. That is to say, in the above - mentioned embodiment, if the same vehicle enters the shopping mall twice in two different time periods, the vehicle is recorded as one trip in the traffic volume statistics. However, in this embodiment, the vehicle is recorded as two trips in the traffic volume statistics. Specifically, one trip is recorded in the first time period and one trip is recorded in the second time period. In this way, the actual vehicle flow situation can be counted, and the accuracy of traffic volume statistics can be further improved.
[0062] In an alternative embodiment, the footprint feature includes at least one of the footprint orientation and the footprint movement time sequence; after determining the same tire footprint as the tire footprint of the same vehicle based on the footprint feature of the tire footprint, the method further includes:
[0063] Determine the moving direction of the vehicle corresponding to the first tire footprint according to at least one of the footprint orientation and the footprint movement time sequence of the first tire footprint, where the first tire footprint is any tire footprint in the pressure - sensitive image sequence;
[0064] Determine the traffic volume information in the first direction in the target area according to the moving direction of each vehicle, where the first direction is any direction in which the vehicle moves.
[0065] In this embodiment, the traffic volume is separately counted based on the moving direction of the vehicles in the target area. Exemplarily, the traffic volume of vehicles entering the scenic area and leaving the scenic area is separately counted. In this way, the special prevention and control requirements for traffic volume statistics in shopping malls, scenic areas, etc. can be met. When specifically implemented, the moving direction of the vehicle can be judged based on the moving direction of the same tire footprint in the pressure - sensitive image sequence or the orientation of the tire footprint, and then the corresponding traffic volume can be counted.
[0066] In the embodiments of the present application, optionally, the target information further includes vehicle information. The vehicle information may include the type information of the vehicle. Specifically, it can be further analyzed based on the footprint feature of the above - mentioned tire footprint. For example, the type of the vehicle can be judged according to the number of the same tire footprints corresponding to the same vehicle, whether it is a tricycle, a sedan, a motorcycle, a long - haul truck, etc.; or for another example, according to the size, texture or tire spacing of different tire footprints. By judging the type information of the vehicle, the traffic volume can be counted separately for different types of vehicles, and the flexibility and comprehensiveness of the application of traffic volume information can be further improved.
[0067] The vehicle information may also include the loading information of the vehicle. Optionally, the target information further includes overweight warning information. Analyzing the pressure sensing information to obtain the target information includes: according to the detected value, when at least one of the detected values meets the preset overweight condition, obtaining the overweight warning information used to characterize that the vehicle in the target area is overweight.
[0068] In specific implementation, the preset overweight condition may be that at least one of the detected values is greater than a preset threshold. By presetting a preset threshold corresponding to an upper loading amount, the preset threshold is of the same type as the detected value. When it is detected that at least one of the detected values is greater than the preset threshold, it can be determined that there is an overloaded vehicle in the currently traveling vehicles. Further, according to the position of the pressure sensing detection unit corresponding to the detected value exceeding the preset threshold, the specific overloaded vehicle is determined to further analyze information such as the vehicle type. The implementation manner of determining the specific overloaded vehicle can refer to the relevant description in the above implementation manner. It can be understood that the preset overweight condition may also be other conditions, which can be specifically determined according to the actual situation and are not specifically limited herein.
[0069] Exemplarily, when it is detected that at least one of the detected values is greater than the preset threshold, the pressure sensing detection unit corresponding to the detected value greater than the preset threshold can be determined, which is denoted as the target pressure sensing detection unit herein. Then, according to the detected value of the target detection unit and the detected values of the pressure sensing detection units around the target pressure sensing detection unit, the target pressure sensing information can be determined, and the target pressure sensing information is analyzed to determine the specific overloaded vehicle.
[0070] For ease of understanding, an example of the embodiment of the present application is described as follows:
[0071] 1) Lay a pressure sensing detection panel / carpet at the entrance and exit of the scenic area parking lot. The pressure sensing detection panel / carpet is provided with a plurality of pressure sensing detection units distributed in an array, and each pressure sensing detection unit can detect a detected value linearly related to the pressure value when being pressed.
[0072] 2) When the vehicle is driving on the pressure sensing detection panel / carpet, the pressure sensing detection units in contact with the vehicle tires can detect the corresponding detected values. The central processor of the pressure sensing detection panel / carpet can summarize the detected values of all pressure sensing detection units at each sampling moment based on the array distribution of the pressure sensing detection units to correspondingly draw the pressure sensing image at each sampling moment and further form a pressure sensing image sequence.
[0073] 3) Using OpenCV, by customizing parameters and image templates, analyze the pressure-sensitive images and the sequence of pressure-sensitive images obtained in 2) to identify the tire imprints in the sequence of pressure-sensitive images and obtain the imprint features of the tire imprints. The imprint features include: imprint orientation, imprint movement time sequence, imprint texture feature, imprint size feature, and imprint pressure feature.
[0074] 4) Based on the imprint features in 3), determine the tire imprints that are the same as each other, and determine the same tire imprints as the tire imprints of the same vehicle, and record a vehicle trip. In addition, the current time can also be recorded, and according to the imprint orientation and / or the imprint movement time sequence, record the driving direction of the vehicle (entering the parking lot or leaving the parking lot).
[0075] 5) Accumulate the "one vehicle trip" information obtained in 4) within a preset time period to obtain the traffic flow information of the parking lot, as well as the number of vehicles entering and the number of vehicles leaving.
