Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a delivery support system according to the present embodiment, and FIG. 2 is a block diagram of a delivery support system according to the present embodiment. The delivered package is loaded inside the delivery vehicle 101 by an operator. A storage shelf 102 for storing luggage is installed inside the delivery vehicle 101, and the storage shelf 102 is divided into a plurality of blocks.

In order to efficiently load packages with various external dimensions, it is desirable to prepare multiple blocks with different dimensions. In the example of FIG. 1, the storage shelf 102 has four types of dimensions (A1 and A2 are 40 cm in height, 100 cm in width and 80 cm in depth, A3 and A4 are 60 cm in height, 100 cm in width and 80 cm in depth, and B1 and B2 are 40 cm in height. , Width 120 cm, depth 80 cm, B3 is composed of a total of seven blocks divided by height 120 cm, width 120 cm, depth 80 cm). Labels indicating the blocks A1 to A4 and B1 to B3 are displayed at the positions of the blocks on the storage shelf 102 so that the operator can easily see them when storing the luggage.

The delivered parcel is stored in each block by the method described later, but it is not always the case that one parcel is stored in each block. When one baggage is stored in a certain block, if there is an empty space (horizontal space or vertical space with respect to the stored baggage) in the block, another baggage is stored. It doesn't matter. In this case, if the empty space remains in the horizontal space, it can be stored side by side with the already stored luggage, and if the empty space remains in the vertical space, it is already stored. It can be stacked and stored on top of the stored luggage.

Inside the delivery vehicle 101, an image pickup device 103 for capturing an internal image of the delivery vehicle 101 is provided. The image pickup device 103 is installed so as to take an image of the storage shelf 102. If the entire storage shelf 102 cannot be imaged by one imaging device 103, a plurality of imaging devices 103 may be used to image the entire storage shelf 102.

FIG. 3 shows a block diagram of the image pickup apparatus according to the present embodiment. The camera 301 captures an image of the storage shelf 102, which is an internal image of the delivery vehicle 101. For the captured image of the storage shelf 102, information on the empty space is detected by performing image analysis on the empty space information detection unit 302.

For example, if the dimensions of each block of the storage shelf 102 correspond to the image area of each block in the image of the storage shelf 102 as the initial setting, the size of the empty space can be increased by comparing with the image area of the stored luggage. Can be detected. Further, when the storage status of the luggage on the storage shelf 102 changes due to loading or unloading of the luggage, the information on the empty space is updated.

The free space information is represented by a combination of a block ID indicating each block and the size of the free space. FIG. 4 is a diagram showing an example of information on free space, and shows information on free space in the example of FIG. In the example of FIG. 1, in the blocks A3, B1 and B3 without luggage, the dimensions of the blocks themselves are the dimensions of the empty space. Further, in the blocks A1, A2, A4, and B2 in which the luggage is already stored, the dimension of the space excluding the luggage is the dimension of the empty space. Here, if a lower threshold value is set for the size of the free space, "no free space" may be set when the size of the free space is equal to or less than the threshold value.

Information on the empty space is transmitted from the image pickup device 103 to the mobile information terminal 104 by wireless communication through the communication unit 303. For wireless communication in the communication unit 303, wireless LAN, short-range wireless communication, cellular communication and the like can be used. Alternatively, a wireless communication means (not shown) installed in the delivery vehicle 101 may be used through the in-vehicle LAN provided in the delivery vehicle 101.

As information on the empty space inside the delivery vehicle 101 transmitted from the image pickup device 103 to the mobile information terminal 104, the internal image data of the delivery vehicle 101 including the image of the storage shelf 102 is input from the image pickup device 103 to the mobile information terminal 104. May be sent to. In this case, the image analysis for detecting the information of the empty space is performed on the mobile information terminal 104.

Next, the operation of the mobile information terminal 104 will be described. FIG. 5 is a block diagram of a mobile information terminal according to the present embodiment. The mobile information terminal 104 is a terminal used by a worker who performs delivery work, and a terminal used for business communication or delivery management, such as a smartphone or a tablet terminal, can be used.

In the package 110 to be delivered loaded on the delivery vehicle 101, the package information related to the package to be delivered is detected by the package information detection unit 501 provided in the mobile information terminal 104 held by the worker. The parcel information includes the number assigned to the parcel (baggage ID), the delivery address, the name of the delivery recipient, the desired delivery date and time, the handling method, the weight, etc., and these information are the package information detection unit 501. It is detected by reading the bar code, the two-dimensional code, or the character of the label attached to the luggage 110 by the bar code reader 502 or the camera 503 included in the package 110.

Further, as luggage information, an external image of the luggage 110 is captured by the camera 503, and the external dimensions of the three sides of the height, width, and depth of the luggage 110 are detected. A known spatial measurement technique using a camera can be used to detect this external dimension. Alternatively, the external dimensions of the luggage 110 may be measured in advance at the time of collection or the like, and the external dimensions may be detected by reading the barcode or the like of the attached label of the luggage 110.

For the detection of the package information, the RFID tag attached to the package may be read instead of the barcode or characters. In this case, the information on the RFID tag is read by using a non-contact communication means (not shown) included in the package information detection unit 501. Further, a part of the package information can be acquired from an external server device that manages various information related to the package by using the communication function of the mobile information terminal 104 based on the read package ID.

The information on the empty space inside the delivery vehicle 101 transmitted from the image pickup apparatus 103 to the mobile information terminal 104 is received by the communication unit 504. For wireless communication in the communication unit 504, wireless LAN, short-range wireless communication, cellular communication and the like can be used. The information on the empty space is a combination of the block ID of the storage shelf 102 and the size of the empty space as described above.

The storage position determination unit 505 compares the size of the empty space included in the information of the empty space received by the communication unit 504 with the external size of the package 110 detected by the package information detection unit 501, thereby inside the delivery vehicle 101. The storage position of the luggage 110, that is, in which block of the storage shelf 102 the luggage 110 should be stored is determined.

This will be described with reference to FIGS. 1 and 4. In FIG. 1, the external dimensions (height 50 cm, width 75 cm, depth 75 cm) of the luggage 110 are detected by capturing an external image of the luggage 110 with the camera 503 of the mobile information terminal 104. Comparing this external dimension with the information on the empty space in FIG. 4, it can be determined that the block in which the luggage 110 can be stored is A3 or B3.

If there is an empty space that can store the luggage according to the external dimensions of the luggage, it can be stored in any block, but if the luggage is heavier than the preset threshold, it can be stored in the lower empty space as much as possible. The burden on the worker may be reduced. As described above, the weight of the package can be detected by the package information detection unit 501 as one of the package information.

Further, when there are a plurality of empty spaces that can be stored, a smaller empty space may be selected to determine the storage position. As a result, even if the external dimensions of the luggage to be loaded later are relatively large, there is a high possibility that the luggage can be stored in the storage shelf 102. Therefore, in the example of FIG. 1, A3 and B3 are compared, and A3, which is a smaller empty space, is determined as the storage position.

Here, if the external dimensions of the package exceed the dimensions of each block of the storage shelf 102 (for example, when the depth is 80 cm or more), the package is placed on the floor inside the delivery vehicle 101, so the storage position is set to "floor". Become. In this case, the luggage is placed at a position that does not interfere with the imaging of the storage shelf 102 by the imaging device 103. If two or more pieces of luggage can be stored in one block (when a space above the lower limit that is considered to be empty when the first piece of luggage is stored can be secured), the block ID is set as the storage position. You can specify the relative position in the block by writing characters such as "right", "left", "top", and "bottom" together. In the example of FIG. 1, the storage positions of the two packages stored in the block A2 are "A2 left" and "A2 right", respectively. In the examples of FIGS. 1 and 4, the lower limit in the height direction and the lower limit in the width direction, which are considered to have empty spaces, are both set to 35 cm.

The storage position information regarding the storage position determined by the storage position determination unit 505 is transmitted from the communication unit 504 to the display device 105. After that, the worker takes the package 110 whose storage position has been determined and loads it into the delivery vehicle 101.

The work history management unit 506 associates the package ID, the external dimensions of the package, and the delivery address corresponding to the package to be delivered detected by the package information detection unit 501 with the storage position determined by the storage position determination unit 505. And manage it as a work history. FIG. 6 is a diagram showing an example of the contents managed as a work history, and shows an example of FIG. 1. By referring to this work history at the time of unloading, it becomes possible to determine the storage position of the load to be unloaded.

The work history managed by the work history management unit 506 is stored in a storage means (not shown) inside the mobile information terminal 104, but is stored in a storage device (for example, an external cloud server) provided outside the mobile information terminal 104. Alternatively, the work history may be transmitted (uploaded) from the communication unit 504 and stored in the image pickup device 103 or a storage means (not shown) provided in the display device 105). As a result, even if the worker is replaced during the work, the work history is received from the externally provided storage device by the communication unit 504 to another mobile information terminal 104 held by the replaced worker ( By making it possible to download), work can be taken over quickly. The work history may be directly transmitted and received between the mobile information terminals 104 of each worker.

Next, the operation of the display device 105 will be described. The display device 105 is installed inside the delivery vehicle 101. FIG. 7 is a block diagram of the display device according to the present embodiment. The storage position information regarding the storage position determined by the storage position determination unit 505 of the mobile information terminal 104 is transmitted from the communication unit 504 of the mobile information terminal 104 and received by the communication unit 701 of the display device 105. For wireless communication in the communication unit 701, wireless LAN, short-range wireless communication, cellular communication and the like can be used. Alternatively, a wireless communication means (not shown) installed in the delivery vehicle 101 may be used through the in-vehicle LAN provided in the delivery vehicle 101.

The projection image generation unit 702 generates a projection image including the storage position information (in the example of FIG. 1, an image including the character "A3" representing a block of the storage position), and the generated projection image is the projection unit 703. Is projected inside the delivery vehicle 101.

The display device 105 shown in FIGS. 1 and 7 is a projection device (projector), but other display devices may be used as long as they can display the storage position information to the operator. For example, the storage position information may be displayed on the panel display installed inside the delivery vehicle 101, or the LED may be installed in each block of the storage shelf 102 to light the LED of the block corresponding to the storage position. ..

When the display device 105 is used as a projection device, the projection location can be arbitrarily set by providing the projection device with a movable portion capable of changing the projection direction of the projection unit 703. For example, when outside light enters from the entrance / exit of the delivery vehicle 101, the visibility can be improved by projecting the projected image on the inner wall surface of the delivery vehicle 101.

Instead of generating the projected image including the storage position information by the projected image generation unit 702, the projected image is generated inside the mobile information terminal 104, and then the projected image is transmitted to the display device 105 for display. It may be configured.

Further, the timing at which the display device 105 starts the display operation may be when the display device 105 receives the storage position information, but a worker carrying the luggage 110 whose storage position has been determined may board the delivery vehicle 101. It may be when it is detected by the image captured by the image pickup device 103. In this case, the image pickup apparatus 103 instructs the display apparatus 105 to start the display operation.

Further, in addition to the display device 105, the storage position information may be displayed on the display unit 507 of the mobile information terminal 104. With this display, the worker can grasp the storage position in advance before loading the luggage. The display unit 507 can also display the package information detected by the package information detection unit 501, the work history managed by the work history management unit 506, information on the empty space inside the delivery vehicle 101, and the like. ..

By visually recognizing the storage position information displayed by the display device 105 installed inside the delivery vehicle 101, the worker performing the delivery work determines the storage position of the package even when the package is held by both hands. This makes it possible for non-skilled workers to easily load luggage.

Further, since the image pickup device 103 images the storage shelf 102, even if the operator mistakenly loads the load in the storage position, it is possible to detect the error in the storage position by image analysis. Specifically, by transmitting the storage position information transmitted from the mobile information terminal 104 to the display device 105 also to the image pickup device 103, the image pickup device 103 recognizes where the storage position of the luggage 110 to be loaded is. it can. When the image pickup device 103 detects by image analysis that the luggage has been stored in an empty space other than the correct storage position, the image pickup device 103 determines that the storage position is incorrect.

In this case, the imaging device 103 notifies the mobile information terminal 104 held by the operator of an error in the storage position, and operates an alarm means (not shown) provided in the mobile information terminal 104. The operator can notice an error in the storage position by the sound or vibration generated by the alarm means. Further, by notifying the display device 105 as well, the projection image generation unit 702 generates a projection image informing that the storage position is incorrect, and the projection image is projected inside the delivery vehicle 101. You can also visually notice the mistake.

If the worker puts the luggage in the wrong direction (for example, the width and depth of the luggage are reversed), or if the storage position of the luggage in the block is not appropriate, the relevant case applies. The remaining empty space in the block containing the luggage may be smaller than planned. In this case, by transmitting the information of the empty space when the luggage is correctly stored from the mobile information terminal 104 to the image pickup device 103, the storage error can be detected by the image analysis in the image pickup device 103. It is possible. When a storage error is detected, the image pickup device 103 notifies the display device 105 of the error status, and the display device indicates a correction method ("change the storage direction", "right-justify storage", etc.). The operator may be notified by projecting from 105 to the inside of the delivery vehicle 101.

FIG. 8 is a flowchart showing a processing procedure at the time of loading a load. First, the image pickup device 103 captures an internal image of the delivery vehicle 101 (S801). Then, information on the empty space inside the delivery vehicle 101 is detected from the captured internal image (S802). This free space information includes the dimensions of the free space. Next, the package information regarding the package delivered by the mobile information terminal 104 is detected (S803). This package information includes the external dimensions of the package to be delivered. Then, the storage position inside the delivery vehicle 101 is determined by comparing the detected size of the empty space with the external size of the delivered package (S804). The storage position information regarding the determined storage position is displayed inside the delivery vehicle 101 by the display device 105 (S805).

Next, the operation when the worker unloads will be described. The parcel loaded on the delivery vehicle 101 is unloaded by the worker at the delivery destination of the parcel. Further, the route that the delivery vehicle 101 goes around the delivery destination of each package in order to unload a plurality of packages is a known route setting method based on the delivery address list (for example, a route setting method that minimizes the mileage). ) May be used in the navigation device 106 installed in the delivery vehicle 101.

The delivery address list can share the delivery address list between the mobile information terminal 104 and the navigation device 106 by transmitting the work history managed inside the mobile information terminal 104 to the navigation device 106. it can. Alternatively, as an alternative to the navigation device 106, a navigation function may be provided inside the mobile information terminal 104 to share the delivery address list.

When the delivery vehicle 101 arrives at the delivery destination according to the guidance of the navigation device 106, the worker starts unloading. First, the geolocation information detection unit 508 included in the mobile information terminal 104 detects a geographic location (latitude, longitude, address, etc.). For the detection of the geographical position, an existing position information detection technique such as GPS may be used. The geographical position can be configured to be shared by the mobile information terminal 104 as detected by the navigation device 106.

The storage position determination unit 505 searches and extracts the delivery address included in a predetermined range from the geographical position detected by the geolocation information detection unit 508 from the work history in the work history management unit 506. Here, the predetermined range is a range in which the worker can perform the delivery work on foot starting from the delivery vehicle 101, and the range can be arbitrarily set by the worker through the input unit 509 of the mobile information terminal 104. As long as it is included in the predetermined range, the number of extracted delivery addresses may be multiple.

By referring to the work history, the parcel ID corresponding to the delivery address extracted as described above, that is, the parcel to be delivered can be selected as the parcel to be unloaded. Then, by referring to the work history as well, it is possible to determine the storage position in which the load to be unloaded is stored.

The work history of FIG. 6 will be described as an example. Since the delivery address of the package ID 10001 and the delivery address of the package ID 10002 are the most different and are included in the predetermined range in which the delivery work can be performed on foot, these two package IDs are selected as the packages to be unloaded. , The worker will carry the two packages, the package ID 10001 and the package ID 10002, from the stopped delivery vehicle 101 on foot.

By referring to the work history, it is determined that the storage positions of the luggage to be unloaded (baggage ID 10001 and luggage ID 10002) are two places, A2 left and A1, and the storage position information of these two places is displayed from the mobile information terminal 104. It is transmitted to the device 105. In the display device 105, a projected image including the two storage positions of A2 left and A1 is generated by the projected image generation unit 702, and the projected image is projected inside the delivery vehicle 101 by the projection unit 703. By getting into the delivery vehicle 101 and visually recognizing the projected image, the operator can easily recognize the storage position and take out the unloading target package from the storage shelf 102 to perform the delivery operation.

In the above example, the worker can take out both of the two packages and perform the delivery work at once, but depending on the size and weight of the packages, it may not be possible to carry the two packages at once. In that case, since the worker takes out the packages one by one from the storage shelf 102 and delivers them, the projected image may be changed according to the work.

FIG. 9 is a diagram showing an example of a projected image. For example, assuming that the display device 105 displays two storage positions, A2 left and A1, as shown in FIG. 9A, when only the luggage stored on the left side of A2 is taken out from the storage shelf 102, The display of the storage position is changed to the display of only A1 as shown in FIG. 9B. In this process, the image analysis in the image pickup apparatus 103 detects the removal of the luggage, that is, the empty space generated by the removal of the luggage, and the information of the empty space is transmitted to the mobile information terminal 104 to perform the work in the work history management unit 506. You can update the history.

Specifically, when the transmitted free space information is compared with the storage position information in the work history, and it is detected that the block previously set as the luggage storage position has become a new empty space. Change the column of the storage position in the work history to "taken out". The storage position of the luggage whose storage position column is "taken out" is not displayed on the display device 105.

FIG. 10 is a flowchart showing a processing procedure at the time of unloading at the delivery destination. When the delivery vehicle 101 arrives at the delivery destination, the mobile information terminal 104 detects the geographical position (S1001). Next, the delivery address included in a predetermined range from the detected geographical position is extracted from the work history (S1002). Then, the storage position determination unit 505 selects the package corresponding to the extracted delivery address as the unloading target package (S1003) by referring to the work history, and the storage position in which the selected unloading target package is stored. Is determined (S1004). The storage position information regarding the determined storage position is displayed inside the delivery vehicle 101 by the display device 105 (S1005).

Further, not limited to the stop location of the delivery vehicle 101, the worker inputs the luggage ID of the luggage to be unloaded from the input unit 509 provided in the mobile information terminal 104, and stores the luggage in the display device 105 inside the delivery vehicle 101. You can also display the position. Based on the baggage ID input to the input unit 509, the storage position determination unit 505 determines the storage position corresponding to the baggage ID by referring to the work history in the work history management unit 506, and the display device 105 indicates the storage position. It can be carried out by transmitting the storage position information regarding the storage position. Here, the form of the input unit 509 may be a physical or virtual keyboard displayed on the touch panel, or the operator may perform voice recognition by inputting voice from the microphone.

The information input by the worker from the input unit 509 does not have to be the package ID itself, and may be other package information such as the delivery address, the delivery recipient name, and the delivery telephone number. If this package information is managed so as to correspond to the package ID in the work history of the work history management unit 506, for example, the name of the delivery destination recipient of the package that the worker wants to unload can be detected from the microphone of the mobile information terminal 104. By inputting by voice, the package corresponding to the input information can be selected as the unloading target package. Then, the storage position in which the unloading target baggage is stored is determined by referring to the work history. The storage position information regarding the determined storage position is transmitted to the display device 105 inside the delivery vehicle 101, and the display device 105 can display the storage position information of the package corresponding to the delivery destination recipient name input by the worker. Will be.

By inputting the input information including any of the baggage information of the baggage that the worker wants to unload to the mobile information terminal 104 in this way, the storage position inside the delivery vehicle 101 of the baggage to be unloaded is displayed. Because it will be possible, workers will smoothly perform unloading work that occurs temporarily in delivery work, such as delivery of packages between workers and delivery of packages to recipients other than the delivery address. It becomes possible.

FIG. 11 is a flowchart showing a processing procedure at the time of unloading based on the input information of the operator. The worker inputs one of the baggage information of the baggage to be unloaded into the input unit 509 of the mobile information terminal 104 (S1101). The input information input by the operator is detected by the input unit 509 (S1102). Then, the storage position determination unit 505 selects the package corresponding to the input information as the unloading target package (S1103) by referring to the work history, and determines the storage position in which the selected unloading target package is stored (S1103). S1104). The storage position information regarding the determined storage position is displayed inside the delivery vehicle 101 by the display device 105 (S1105).

Further, in the delivery work, redelivery may be required when the delivery destination's private home or the like is absent, and the worker takes the package once taken out from the storage shelf 102 back to the delivery vehicle 101 from the delivery destination. The work of loading onto the storage shelf 102 occurs again. Here, when the worker loads the parcel to be redelivered, if the parcel loading process described above is performed again, the parcel can be returned to the appropriate storage position and the work history is also updated. ..

The storage position when returning the package does not necessarily have to be the original storage position, and the empty space created in the process of delivery work may be used as the new storage position. If the empty space created near the entrance / exit of the delivery vehicle 101 is used as a new storage position for returning the parcel, the movement distance of the worker inside the delivery vehicle 101 will be reduced, and the work load for redelivery will be reduced. To.

The process of reloading the package is also performed even when the storage position of the package changes during the delivery work. For example, if two pieces of luggage are stacked and stored in one block of the storage shelf 102, and if the lower piece of luggage is to be unloaded first, the upper piece of luggage is once stored in the storage shelf. Must be removed from 102. In that case, after the removal of the lower package and the delivery to the delivery destination are completed, the work history is updated by performing the loading process again for the upper package.

The display device installed inside the delivery vehicle 101 may be configured to have a plurality of different types of display devices installed. For example, when the display device is configured to light the LED of the block corresponding to the storage position of the storage shelf 102, the operator cannot visually recognize the LED unless he / she advances in the vehicle to the vicinity of the front of the block. Therefore, a projection device or a panel display is installed near the entrance / exit of the delivery vehicle 101 as an auxiliary display device, and guidance display is performed for each row of storage shelves (A, B in the example of FIG. 1). This guidance display may be a character indicating a row of the storage shelves 102, or may be an arrow indicating a certain direction of the storage shelves 102.

With such a configuration, the operator can determine in which block of the storage shelves the luggage should be stored when the worker has advanced to the front of the row of the storage shelves including the block of the storage position, so that the loading work can be performed. Greater convenience.

As described above, according to the present embodiment, it is possible to determine the storage position of the luggage so as to effectively utilize the empty space inside the delivery vehicle, and it is possible to improve the loading efficiency.
