  Hereinafter, embodiments of a traffic path determination system according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 shows a traffic path determination system 1 according to the present embodiment. As shown in FIG. 1, the traffic path determination system 1 includes a camera 10 and a server 20. The traffic path determination system 1 is a system that determines the state of a traffic path. The road to be determined is a bridge or road through which a vehicle such as an automobile passes. The state of the determined road is, for example, whether or not an abnormality has occurred in the road (for example, deterioration has occurred). Or the state of a to-be-determined path is a deterioration state (deterioration degree) of a to-be-routed road, the soundness state (soundness degree) of a to-be-routed road, etc. The result of the determination by the traffic path determination system 1 is used, for example, for determination of reinforcement or repair of the traffic path. In the traffic path determination system 1, the state of the traffic path is determined by the server 20 using an image captured by the camera 10.

  Subsequently, the configuration of the camera 10 and the server 20 included in the traffic path determination system 1 will be described. The camera 10 is an imaging device that captures a moving image by capturing an image of an object such as a vehicle traveling on a determination target path. The camera 10 is fixedly installed in advance at a position where the object can be imaged. As the camera 10, a known camera capable of imaging with a resolution that can be used for processing by the server 20 described later can be used. The camera 10 and the server 20 can exchange information with each other. The camera 10 captures the traffic path at a preset frame rate (fps) and transmits the captured moving image to the server 20.

  Moreover, the camera 10 is good also as imaging the moving image for detecting the vibration of a traffic path. The moving image may be the same as the moving image obtained by imaging the object passing through the above-described passage, or may be a different moving image. When different moving images are used, the camera 10 is provided for each moving image. The camera 10 that captures a moving image for detecting the vibration of the traffic path is fixedly installed in a position where the traffic path can be captured in advance. The moving image for detecting the vibration of the road is taken at the same timing as the moving image of an object such as a vehicle passing through the road. The camera 10 also transmits the moving image to the server 20.

  As shown in FIG. 1, the server 20 is functionally configured to include an image acquisition unit 21, an object identification unit 22, a vibration acquisition unit 23, a determination unit 24, and an output unit 25.

  The image acquisition unit 21 is a functional unit that acquires an image obtained by imaging an object passing on a traffic path. The image acquisition unit 21 receives a moving image transmitted from the camera 10 and acquires the image. The image acquisition unit 21 outputs the acquired moving image (image) to the object specifying unit 22 and the vibration acquisition unit 23.

  The object specifying unit 22 is a functional unit that specifies an object that passes on a traffic path from the image acquired by the image acquiring unit 21. The object specifying unit 22 specifies the speed of the passing object from the image acquired by the image acquisition unit 21.

  The object specifying unit 22 inputs a moving image from the image acquisition unit 21. For example, the object specifying unit 22 specifies the vehicle type of a vehicle such as an automobile that passes on the road as an object that passes on the road. The object specifying unit 22 specifies the vehicle type of the vehicle from a frame (image) at a preset timing in the moving image. The vehicle type can be specified using a known method such as pattern recognition. FIG. 2 schematically shows an example of a vehicle type identification method.

  The object specifying unit 22 stores an image database in advance. The image database is a database storing a vehicle image that is used to extract a portion in which the vehicle is captured from an image input from the image acquisition unit 21. The object specifying unit 22 extracts, from the image input from the image acquisition unit 21, a portion in which the vehicle is shown from the cascade classifier stored in advance and the image stored in the image database.

  The object specifying unit 22 stores a vehicle database in advance. The vehicle database is a database that stores vehicle images that are used to identify the vehicle type from the extracted partial images. An example of a vehicle database is shown in FIG. As shown in FIG. 3, the vehicle database stores an image of the vehicle for each vehicle type. In the vehicle database, information indicating the weight of the vehicle may be stored in association with each vehicle type.

  The object specifying unit 22 specifies the vehicle type from the extracted partial image based on the cascade classifier stored in advance (different from the cascade classifier for extracting the partial image) and the image stored in the vehicle database. .

  Moreover, the object specific | specification part 22 specifies the speed of the vehicle which specified the vehicle type. The object specifying unit 22 calculates the pixel displacement of the vehicle by optical flow from each frame (image) constituting the moving image. The object specifying unit 22 calculates the displacement amount of the vehicle in the real space from the calculated pixel displacement and the distance in the real space per pixel that is set or calculated in advance. The object specifying unit 22 calculates the speed of the vehicle from the calculated displacement of the vehicle and the frame rate of the moving image. Note that the specification (calculation) of the speed of the vehicle from the moving image is not necessarily performed by the above method, and may be performed by any conventional method. The object specifying unit 22 outputs information indicating the vehicle type and speed of the specified vehicle to the determination unit 24.

  The vibration acquisition unit 23 is a functional unit that acquires information indicating the vibration of the road when the object specified by the object specifying unit 22 passes on the road. The vibration acquisition unit 23 acquires a moving image obtained by imaging the passage, and detects vibration of the passage from the acquired moving image.

  The vibration acquisition unit 23 inputs and acquires a moving image obtained by capturing a road for detecting the vibration of the road from the image acquisition unit 21. The vibration acquisition unit 23 detects a displacement on a sub-pixel basis from the moving image by a conventional technique such as POC (Phase Only Correlation), and detects a vibration of a traffic path. For example, the vibration acquisition unit 23 detects vibration as follows.

  The vibration acquisition unit 23 divides the acquired moving image into individual frames (images) constituting the moving image as shown in FIG. The vibration acquisition unit 23 extracts (divides into partial images) partial images (phase images) of a plurality of regions at preset positions from individual frames. In the present embodiment, each region is referred to as an element E. The size of the element E is set in advance. The position of the element E is a position where the traffic path is reflected in the moving image. The position of the element E is set in advance by the user of the traffic path determination system 1 and stored in the vibration acquisition unit 23, for example. Alternatively, the vibration acquisition unit 23 may detect the position where the traffic path is reflected in the moving image and set the detected position as the position of the element E.

  The vibration acquisition unit 23 calculates the positional deviation of the same (position) element E between the previous and subsequent frames with sub-pixel accuracy. The time difference Δt between the previous and next frames is the reciprocal of the frame rate (fps) (Δt = 1 / fps). For example, when determining the state of the bridge, the vibration acquisition unit 23 calculates a positional shift in the y direction of the moving image. This is because the deterioration of the bridge proceeds according to the vibration in the vertical direction (vertical direction). The vibration acquisition unit 23 calculates a positional deviation (displacement y) between the front and rear frames for each element from the moving image as vibration of the passage. The vibration data obtained from the moving image by the vibration acquisition unit 23 is data of displacement y for each element i and time (time) t as shown in FIG. The vibration acquisition unit 23 outputs the obtained vibration data to the determination unit 24.

  Note that the information indicating the vibration of the passage acquired by the vibration acquisition unit 23 and the information indicating the object (vehicle type or the like) specified by the object specifying unit 22 are associated with each other. The association is performed so that the vibration of the traffic path is the vibration of the traffic path when the identified object passes on the traffic path. Specifically, vibration detected (identified) from an image (moving image) captured at the same timing is associated with an object. Further, in the above example, vibrations at a plurality of locations (elements) on the traffic path are detected, but it is not necessary to be at a plurality of locations, and vibration at one location may be detected.

  The determination unit 24 is a functional unit that determines the state of the traffic path based on the object specified by the object specifying unit 22. The determination unit 24 determines the state of the traffic path based also on the speed of the object specified by the object specifying unit 22. The determination unit 24 determines the state of the traffic path by comparing vibrations at different timings indicated by the information acquired by the vibration acquisition unit 23 according to the object specified by the object specifying unit 22.

  The vibration of the road due to the passage of the vehicle or the like is in accordance with the state such as deterioration of the road. Therefore, it is possible to grasp the state such as deterioration of the traffic path by comparing the vibrations of the time-series traffic path. However, on the other hand, the vibration of the traffic path corresponds to the vehicle or the like that passes. For example, the vibration of the traffic path differs between when a heavy vehicle passes and when a light vehicle passes. In that case, even if these vibrations are compared, it is not possible to properly grasp the state such as deterioration of the traffic path. In the present embodiment, vibrations to be compared with each other are appropriate depending on the object specified by the object specifying unit 22.

  As described above, the determination by the determination unit 24 is performed based on the vibration of the traffic path at different timings. For this reason, the object specifying unit 22 specifies an object from moving images captured at a plurality of different timings, and the vibration acquisition unit 23 detects the vibration of the traffic path. The determination unit 24 inputs information about the object and vibration identified from the moving image captured at each timing from the object identification unit 22 and the vibration acquisition unit 23.

  For example, the determination unit 24 determines the state of the passage by comparing vibrations when vehicles of the same vehicle type are passing. For example, the determination unit 24 determines the state by comparing the natural frequencies at different timings. The determination unit 24 Fourier-transforms the vibration data at each timing (data of the displacement y at each time (time) t) input from the vibration acquisition unit 23. The vibration data by Fourier transform becomes data of intensity (power) for each frequency (Hz) as shown in FIG. The determination unit 24 calculates (detects) a natural frequency (dominant frequency) from vibration data obtained by Fourier transform. The natural frequency is, for example, the lowest frequency among the frequencies at which the intensity becomes a maximum value. In general, it is said that the natural frequency decreases when a bridge deteriorates. The determination unit 24 calculates a natural frequency for a moving image captured at a plurality of timings as illustrated in FIG. 5, and if the natural frequency is lower than a preset threshold value, the passage is deteriorated. Judge. In addition, when the vibration of a traffic path is detected for every element, it is good also as judging for every element (location).

  For example, the determination unit 24 divides the vehicle speed at regular intervals, and compares vibrations when vehicles of the same vehicle type are traveling in the same speed range to determine the state of the passage. It is good. In addition, the determination unit 24 divides the weight of the vehicle at regular intervals, for example, compares vibrations when a vehicle with the same range of weight is passing instead of the vehicle type, and determines the state of the passage. It may be determined.

  Further, the determination unit 24 acquires information indicating an environment related to the passage when the object specified by the object specifying unit 22 passes on the road, and is also based on information (external information) indicating the environment. Thus, the state of the traffic path may be determined. As information indicating the environment, for example, the weather or temperature of the passage on the vibration detection timing is used. Such information may be obtained by providing a road sensor, or weather forecast information may be obtained from an external server or the like. Weather and air temperature can also affect the vibration of the road. The determination unit 24 may determine the state of the traffic path by comparing vibrations in the case of the same weather or the same range of temperature in addition to the vehicle type based on the information indicating the acquired environment. Good.

  The determination unit 24 outputs information indicating the determination result to the output unit 25, for example, information indicating whether or not the passage is degraded.

  The output unit 25 is a functional unit that outputs information indicating the determination result of the traffic path state by the determination unit 24. For example, the output unit 25 transmits and displays the information to a terminal connected to the server 20. The output from the output unit 25 is referred to, for example, by the user of the traffic path determination system 1 and is used for determination of reinforcement or repair of the traffic path as described above. Note that the output by the output unit 25 may be performed on a device other than the above and in a form other than the above. The above is the configuration of the traffic path determination system 1.

  Subsequently, a process executed by the traffic path determination system 1 according to the present embodiment (an operation method performed by the traffic path determination system 1) will be described with reference to the flowchart of FIG. First, the camera 10 captures an image of a road to be determined and a vehicle passing through the road, and acquires a moving image (S01). The captured moving image is transmitted from the camera 10 to the server 20. In the server 20, a moving image is acquired by the image acquisition unit 21. Subsequently, the vehicle type and speed of the vehicle are specified from the moving image by the object specifying unit 22 (S02). Further, the vibration acquisition unit 23 detects the vibration of the traffic path from the moving image (S03). The imaging (S02), the identification of the vehicle type (S02), and the detection of the vibration of the traffic path (S03) are performed at a plurality of different timings.

  Subsequently, the determination unit 24 compares the vibrations at different timings according to the specified vehicle type and the like, and determines the state of the passage (S04). Subsequently, the output unit 25 outputs information indicating the determination result of the traffic path state by the determination unit 24 (S05). The above is the processing executed by the traffic path determination system 1 according to the present embodiment.

  In the present embodiment, an object such as a vehicle passing on a traffic path is identified from the image, and the state of the traffic path is determined based on the identified object. Therefore, even if a strain sensor or the like is not provided on the passage, it is possible to make a determination according to the object that has passed the passage. Further, the object can be appropriately identified as compared with the case of using a strain sensor or the like. Therefore, according to the present embodiment, it is possible to easily and appropriately determine the state of a traffic path such as a bridge.

  Moreover, it is good also as determining a traffic path based also on speed like this embodiment. As described above, the speed of a vehicle or the like passing through the road also affects the vibration of the road. Therefore, according to this configuration, it is possible to more appropriately determine the state of the traffic path. However, it is not always necessary to use the speed for determining the traffic path.

  Moreover, it is good also as acquiring the information which shows the vibration of a traffic path like this embodiment, and comparing a vibration according to the specified object and determining the state of a traffic path. According to this configuration, it is possible to make an appropriate determination using the vibration of the traffic path. However, in the present invention, the determination may be made by specifying the vehicle from the image, and the determination using vibration is not necessarily performed.

  In addition, as in the present embodiment, when determination is performed using vibration, vibration may be detected from a moving image. According to this configuration, it is possible to perform the determination from the moving image captured including the identification of the object, and it is possible to easily and appropriately determine the state of the traffic path. However, the vibration detection is not necessarily performed by a moving image, and may be performed by a vibration sensor or the like provided on the passage.

  Moreover, it is good also as determining a traffic path based also on the information which shows environments, such as weather or temperature, like this embodiment. As described above, the environment such as weather or temperature also affects the vibration of the traffic path. Therefore, according to this configuration, it is possible to more appropriately determine the state of the traffic path. However, it is not always necessary to use information indicating the environment for determining the traffic path.

  In the present embodiment, the camera 10 captures and acquires a moving image. However, when only the vehicle type is specified from the image, the moving image is not necessarily acquired, and the image is acquired. May be.

  Further, the traffic path determination system according to the present invention only needs to be able to acquire an image or a moving image, and therefore may be configured to acquire a moving image from other than the traffic path determination system. For example, if the server 20 according to the present embodiment has a configuration capable of acquiring an image or a moving image from the camera 10 (other than the traffic path determination system), even if the traffic path determination system is configured only by the server 20. Good.

  Moreover, in this embodiment, although the example of the object which passes along a traffic path was assumed to be vehicles, such as a motor vehicle, the said object may be vehicles other than a motor vehicle or things other than a vehicle (for example, person). For example, it is good also as determining the state of a traffic path according to the number of passers-by instead of the said vehicle model. Further, the determination target passage may be a track on which a train or the like passes. In this case, the object passing through the road may be a vehicle such as a train.
