Description

[Technical field]

[0001] The present invention relates to a vehicle guidance system, a vehicle guidance method, and a program for a waste treatment facility. [Background technology]

[0002] 2. Description of the Related Art A system is known that notifies workers in a facility of precautions by projecting safety signs using a projector (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6364568 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, when notifying workers in a facility of important matters, the workers manually switch the information to be projected by the projector.

[0005] In addition to compactor trucks (so-called garbage trucks) that frequently visit waste treatment facilities for work, citizens who visit infrequently also visit to dispose of waste. Waste treatment facilities have an area called a platform. The platform is equipped with multiple garbage input doors, a garbage pit where garbage input through the multiple garbage input doors is accumulated, and a stage where vehicles that input garbage from the garbage input doors to the garbage pit temporarily stop. Citizens need to unload garbage from their vehicles on the stage. However, citizens also unload garbage on the same stage where multiple compactor trucks and the like are unloading, so further safety is required in places where many vehicles pass by. In waste treatment facilities, it is usually possible to guide compactor vehicles that come for work by simple indications such as the color and state of lights, but simple indications are difficult to understand for citizens who visit infrequently. For example, on the stage, the unloading locations for waste are different for commercial vehicles and citizen vehicles, and there are cases where there are no guidance indications such as lights at the unloading locations for citizen vehicles. Therefore, the staff of the waste treatment facility guide citizens by gestures and calling out. Digital signage (so-called electric display boards) are also used to guide visitors, but since they are hung from the ceiling and installed above the facility, visitors who are driving vehicles must move their eyes from the front to the top, which is undesirable from the perspective of safety. Furthermore, large digital signage must be adopted to display text information, and visitors must memorize the text information, making it difficult to convey complex information.

[0006] There is a need for a vehicle guidance system and method for a waste treatment facility that can automatically guide citizens who do not visit the facility frequently to their destination and convey information to them. [Means for solving the problem]

[0007] The present invention has been made against this background, and aims to provide a vehicle guidance system, a vehicle guidance method, and a program for a waste treatment facility that can automatically guide and transmit information to a destination, even to citizens who do not visit the facility frequently.

[0008] In order to solve the above problems and achieve the above object, the present invention proposes the following means. A first aspect of the present invention is a vehicle guidance system at a waste treatment facility, comprising: a control unit that associates the vehicle with a waste disposal location of a visitor to the waste treatment facility who is riding in a vehicle; a vehicle position detection unit that is provided on a platform of the waste treatment facility, which has a floor, walls, a ceiling, and a drop door to the disposal location, and detects the position of the vehicle within the platform; and a projector that is provided on at least one of the walls or the ceiling of the platform, and projects an image onto at least one of the floor and the walls to guide the vehicle to the drop door, wherein the control unit switches the image depending on the position of the vehicle.

[0009] According to the first aspect of the present invention, even if citizens who do not visit a waste treatment facility frequently come, visual information can be effectively provided to them, so that they can be automatically guided to their destination and information can be conveyed to them.

[0010] A second aspect of the present invention is a vehicle guidance system in a waste treatment facility, wherein in the first aspect, the vehicle position detection unit is a camera.

[0014] A fourth aspect of the present invention is a vehicle guidance system in a waste treatment facility, wherein, in any one of the first to third aspects, the platform further comprises a speaker that outputs automated voice guidance simultaneously with projecting the image.

[0015] According to a fourth aspect of the present invention, even if a citizen who does not visit a waste treatment facility frequently comes, it is possible to automatically guide the citizen to the desired location and convey information to the citizen by effectively providing auditory information in addition to visual information.

[0016] A fifth aspect of the present invention is a vehicle guidance method at a waste treatment facility, comprising: an association process for associating the vehicle with a waste disposal location of a visitor to the waste treatment facility who is riding in the vehicle; a vehicle position detection process for detecting the position of the vehicle within a platform of the waste treatment facility, which has a floor, walls, a ceiling, and a drop door to the disposal location; and a projection process for projecting an image onto at least one of the floor and walls to guide the vehicle to the drop door, and switching the image depending on the position of the vehicle.

[0017] According to a fifth aspect of the present invention, even if a citizen who does not visit a waste treatment facility frequently comes, visual information can be effectively provided to the citizen, so that the citizen can be automatically guided to the desired location and information can be conveyed to the citizen.

[0018] A sixth aspect of the present invention is a method for guiding vehicles in a waste treatment facility, wherein, in the projection step, the image is projected onto an existing road marking on the floor or wall of the platform.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] (First embodiment) DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vehicle guidance system, a vehicle guidance method, and a program for a waste treatment facility according to a first embodiment of the present invention will be described below with reference to the drawings.

[0029] 1 is a schematic diagram of a vehicle guidance system 20 in a waste treatment facility according to a first embodiment of the present invention (hereinafter, may be simply referred to as the vehicle guidance system 20). The vehicle guidance system 20 is provided in the waste treatment facility. Before describing the vehicle guidance system 20, the waste treatment facility will be described.

[0030] Waste treatment facilities include both facilities that incinerate waste and facilities that recycle waste. The waste treatment facility is provided with a section called a platform P. The platform P is provided with a dump door 5 through which a vehicle V loaded with waste dumps the waste into a predetermined location (e.g., a garbage pit). The platform P is an indoor facility that includes an entrance 1, an exit 2, a wall surface 3, a floor surface 4, a dump door 5, a ceiling 6, and a projector 10. A plurality of dump doors 5 and projectors 10 may be provided. In the first embodiment of the present invention, it is assumed that the input doors 5 (5a, 5b) used by citizens and the input doors 5 (5c, 5d) used by compactor trucks for business purposes are provided on the same platform P. In addition to the platform P, the waste treatment facility is provided with a reception desk (not shown), a chimney (not shown), an incinerator (not shown), etc. In the following explanation, it is assumed that the input doors 5 (5a, 5b) used by citizens and the input doors 5 (5c, 5d) used by compactor trucks for business purposes are located on the same platform P, but the present invention is not limited to this case.

[0031] A visitor usually loads waste into a vehicle and drives the vehicle himself or herself or has a passenger drive the vehicle to the waste treatment facility. The visitor declares the type of waste at the reception desk. At the reception, a decision is made as to which input door 5 of the platform P the waste should be disposed of at, depending on the contents of the declared waste. This input door 5 is the destination for the visitor's vehicle. At the reception, the destination location of the visitor's vehicle (ie, any of the entry doors 5a, 5b, 5c, 5d) is associated with the identification information of the visitor's vehicle. The identification information is, for example, the license plate number of a vehicle, or an identification number recorded in a recording device distributed to visitors at the reception desk. The recording device is, for example, an IC card. The controller 50 of the vehicle guidance system 20 associates the destination of the visitor's vehicle with the identification information of the visitor's vehicle. This is called an association process. The controller 50 will be described later.

[0032] 2 is a block diagram showing an example of a vehicle guidance system 20 in a waste treatment facility according to the first embodiment. The system configuration of the vehicle guidance system 20 will be described with reference to FIG.

[0033] The reception area is provided with an information input device 40 capable of transmitting identification information to the control unit 50. The information input device 40 is, for example, a personal computer. The reception desk may further be provided with an information reading device 60 for reading the identification information. The information reading device 60 is, for example, a camera or an IC card reader. When the information reader 60 is a camera, the characters on the license plate, which are the identification information photographed by the camera, are automatically recognized by a known method and transmitted to the control unit 50 via the information input device 40 . When the information reading device 60 is an IC card reader, the identification number recorded on the IC card is transmitted to the control unit 50 via the information input device 40 . In addition, when the information reading device 60 is provided, the identification information may be transmitted directly from the information reading device 60 to the control unit 50 without going through the information input device 40. In this case, the information input device 40 does not need to be provided.

[0034] The vehicle guidance system 20 includes a control unit 50, a vehicle position detection unit 30, and a projector 10. The control unit 50 associates the vehicle V with the disposal location of the waste of a visitor to the waste treatment facility who is riding in the vehicle V. The vehicle position detection unit 30 is provided on the platform P and detects the position of the vehicle V within the platform P. This is called a vehicle position detection process. The projector 10 is provided on at least one of the wall surface 3 and the ceiling 6 of the platform P, and projects an image that guides the vehicle V to the input door 5 onto at least one of the floor surface 4 and the wall surface 3. Moreover, the control unit 50 switches the image depending on the position of the vehicle V detected by the vehicle position detection unit 30. This is called a projection process. The control unit 50 is a computer including a processor such as a CPU (Central Processing Unit) and a memory. The processor executes arithmetic processing for executing the functions of the control unit 50. The memory stores a rewritable program in which the functions executed by the CPU are described. The control unit 50 may realize these functions using hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit). Alternatively, the functions of the control unit 50 may be realized by a collaboration between software and hardware. The program will be described later.

[0035] 3 is a schematic diagram showing the vehicle guidance system 20 in the waste treatment facility according to the first embodiment of the present invention, as viewed from above. The operation of the vehicle guidance system 20 will be described in detail with reference to FIG.

[0036] When the destination of vehicle V1 determined at reception to be the input door 5b, vehicle V1 is prompted to stop in front of the "Stop" road sign and the stop line present near input door 5b. This is because the projector 10 projects an image (image S6) of a blinking rectangular dotted line surrounding the "Stop" traffic sign just before the stop line, which is located ahead in the direction of travel as seen from vehicle V1 that has entered platform P from entrance 1, so that the entrant driving vehicle V1 can recognize the "Stop" traffic sign and the stop line without having to move his or her line of sight. Also, a voice for stopping the vehicle V1 before the stop line (for example, voice 6 meaning "Please stop before the stop line") may be output from the speaker 70a. Here, speaker 70a is provided near the stop line, speaker 70b is provided near input door 5a, speaker 70c is provided near input door 5b, speaker 70d is provided near input door 5c, and speaker 70e is provided near input door 5d.

[0037] The fact that the vehicle V1 has stopped in front of the stop line is detected by the vehicle position detection unit 30. The vehicle position detection unit 30 is, for example, a camera or a sensor. When the vehicle position detection unit 30 is a camera, a known image analysis method is used to detect that the vehicle V1 has stopped in front of the stop line. The camera is disposed on one of the wall surface 3, the floor surface 4, and the ceiling 6, or a combination thereof. In the example of FIG. 3, the camera is disposed on the floor surface 4. When the vehicle V1 stops in front of the stop line, the vehicle position detection unit 30 transmits a signal to the control unit 50 notifying the control unit 50 that the vehicle V1 has stopped in front of the stop line. In response to this signal, the control unit 50 causes the projector 10 to stop projecting the image S6, and subsequently causes the projector 10 to project images S1 to S4 for guiding the vehicle V1 to the input door 5b. The images S1 to S4 will be described later. When the vehicle position detection unit 30 is a sensor, for example, if a weight sensor that detects the weight of the vehicle is placed in front of the stop line, it is possible to detect that the vehicle has stopped in front of the stop line by the weight detected by the weight sensor. In this case, it is preferable that the floor surface 4 on which the weight sensor is provided is configured to be able to float and sink depending on the vehicle weight. In this way, the vehicle weight can be detected even if the weight sensor is not in contact with the tires of the vehicle V1. Alternatively, multiple weight sensors may be provided at points where the tires of the vehicle V1 pass, and any one of them may detect the vehicle weight. The sensor is not limited to a weight sensor, and for example, if an illuminance sensor is placed in front of the stop line, when the vehicle stops in front of the stop line, the shadow of the vehicle is cast in the area where the illuminance sensor is placed, and the stopping of the vehicle can be detected by the change in illuminance. Also, a range sensor (optical distance sensor) may be used to grasp the position of the vehicle.

[0038] When the vehicle position detection unit 30 detects that the vehicle V1 is stopped in front of the stop line, the control unit 50 causes the projector 10 to project images S1 to S4 on the floor surface 4, which guide the vehicle V1 to the waste deposit door 5b, and further causes the projector 10 to project an image S5, which encourages the user to deposit waste, on the waste deposit door 5b. The images S1 to S5 will be described in detail below with reference to FIG. 3.

[0039] That is, an arrow (image S1) extending forward while curving to the left is projected from the projector 10 onto the floor surface 4 in front of the stop line. Furthermore, a vehicle image (image S2) representing the vehicle V is projected from the projector 10 onto the floor surface 4 in front of the arrow (image S1). Furthermore, an arrow (image S3) extending from the floor surface 4 behind the vehicle image (image S2) representing the vehicle V to the input door 5b is projected. Furthermore, a rectangular image (image S4) with diagonal lines representing the vehicle V parked is projected from the projector 10 onto the floor surface 4 in front of the input door 5b, within the parking space P2 of the input door 5b. An image of the vehicle V backing up toward the input door 5b (an image of the image S2 moving toward the input door 5b) may be projected between the images S3 and S4. Here, the parking space P2 means a corner of the stage, which is an area where the vehicle V temporarily stops to deposit waste into the garbage pit from the input door 5b. More specifically, the areas where the vehicle V temporarily stops to deposit waste into the garbage pit from each of the input doors 5a, 5b, 5c, and 5d will be described as parking spaces P1, P2, P3, and P4.

[0040] The above series of images S1 to S4 are projected when the vehicle V1 is stopped at the stop line. The driver of the vehicle V1 who sees this can recognize that he is being prompted to back into the parking space P2 in front of the input door 5b.

[0041] 5, the word "Go" (image S8) is projected from the projector 10 onto the floor surface 4 in front of the stop line. This allows the driver of the vehicle V1 to execute the actions of the series of images S1 to S4. At this time, a voice for starting the vehicle V1 (for example, voice 8 meaning "Go forward to the left, then back up toward the parking space in front of the entrance door") may be output from the speaker 70a. Here, simultaneously with the projection of the images S1 to S4, a voice may be output from the speaker 70a to guide the vehicle V1 to the parking space P2 in front of the input door 5b. Note that the voice may be referred to as an automatic voice. As an example of a voice, when vehicle V1 stops before the stop line, voice 1 meaning "We will now guide your vehicle to the loading door 5b. The guidance method will be projected onto the floor, so when the "proceed" message appears, please move your vehicle in that direction" is output from speaker 70a. Next, at the same time that images S1 to S2 are projected, voice 2 meaning "First, move the car forward to the left" is output from speaker 70a. Next, at the same time as the image S3 is projected, a voice 3 meaning "Next, put the shift lever into reverse and back up toward the parking space in front of the loading door 5b" is output from the speaker 70a. Next, at the same time as the image S4 is projected, a voice 4 meaning "The train will now stop in front of the input door 5b" is output from the speaker 70a.

[0042] When the vehicle position detection unit 30 detects that the vehicle V1 has stopped in the parking space P2 in front of the input door 5b, text (image S5) such as "Please insert waste (garbage)" may be displayed on the input door 5b. At the same time as the image S5, a voice 5 saying "Please insert waste (garbage)" may be output from the speaker 70b. The image S5 can be seen through the rearview mirror even when the visitor is seated in the driver's seat. This allows citizens to discard waste through the input door 5 (5a, 5b) for citizens, or to pile up waste in the open if a temporary waste storage area is provided around the input door 5 (5a, 5b). The temporary waste storage area will be described later. 6, when the word "Go" (image S9) is projected by the projector 10 onto the floor surface 4 in front of the vehicle V1, the vehicle V1 starts moving toward the exit 2 and leaves the platform P from the exit 2. At this time, a sound for starting the vehicle V1 (for example, a sound 9 meaning "Please proceed toward the exit on the right front") may be output from the speaker 70b.

[0043] Here, a plurality of vehicle position detection units 30 may be provided. For example, the stopping of the vehicle V1 before the stop line and the stopping of the vehicle V1 in the stopping space P2 before the input door 5b may be detected by different vehicle position detection units 30 arranged on the floor surface 4 before the stop line and on the floor surface 4 of the stopping space P2.

[0044] Here, a deep garbage pit is provided beyond the input door 5 (5c, 5d) that is used by contractors who arrive by compactor trucks for business purposes. Therefore, a safety belt (lifeline) (not shown) is provided near the input door 5 (5c, 5d) to prevent visitors from falling into the garbage pit, and visitors must wear the safety belt when working around the vehicle V. Therefore, when the reception determines that the visitor's attributes are those of a contractor who arrived by compactor truck, the vehicle V is first guided to the parking space P (P3, P4) in front of the business input door 5 (5c, 5d) in the manner described above. Next, when the vehicle position detection unit 30 detects that the vehicle V has stopped in the parking space P (P3, P4) in front of the input door 5 (5c, 5d), the control unit 50 may display text (image Sa) (not shown) such as "Please wear a safety belt" on the input door 5 (5c, 5d) before projecting the image S5 onto the input door 5 (5c, 5d). At the same time, the control unit 50 may output from the speaker 70 a sound Sa meaning "Please wear a safety belt when working outside the vehicle." Furthermore, for example, regardless of whether the visitor is a trader who arrived in a compactor truck or a citizen, if the vehicle position detection unit 30 is a camera, the camera can detect the positions of the vehicle V and the visitor, and if the visitor who gets out of the vehicle V approaches the loading door 5 more closely than necessary, a warning sound can be output from the speaker 70. Furthermore, on the platform P, areas that are dangerous for visitors to approach may be set as no-go areas in advance, and the projector 10 may project onto the floor surface 4 of the no-go areas.

[0045] Furthermore, if the visitor's attribute is determined to be a citizen at the reception, the control unit 50 may project information for citizens or an image for children (not shown) on the wall surface 3 facing the input door 5 (5a, 5b) after the vehicle position detection unit 30 detects that the vehicle V1 has stopped in the parking space P (P1, P2) in front of the input door 5 (5a, 5b). That is, the control unit 50 may project different images based on the visitor's attributes.

[0046] As described above, the vehicle guidance system 20 of this embodiment includes a control unit 50 that associates the vehicle V with the waste disposal location of a visitor to the waste treatment facility who is riding in the vehicle V, a vehicle position detection unit 30 that is provided on a platform P of the waste treatment facility, which has a floor 4, walls 3, a ceiling 6, and a drop door 5 to the disposal location, and detects the position of the vehicle V within the platform P, and a projector 10 that is provided on at least one of the walls 3 or the ceiling 6 of the platform P and projects an image onto at least one of the floor 4 and the wall 3 to guide the vehicle V to the drop door 5, and the control unit 50 switches the image depending on the position of the vehicle V. In addition, the vehicle guidance method of this embodiment includes an association process for associating the vehicle V with the waste disposal location of a visitor to the waste treatment facility who is riding in the vehicle V; a vehicle position detection process for detecting the position of the vehicle V within a platform P of the waste treatment facility, which has a floor 4, wall 3, a ceiling 6, and a drop door 5 to the disposal location; and a projection process for projecting an image onto at least one of the floor 4 and the wall 3 to guide the vehicle V to the drop door 5, and switching the image depending on the position of the vehicle V. In addition, the program related to this embodiment is a program that causes a computer to execute an association step of associating the vehicle V with the waste disposal location of a visitor to the waste treatment facility who is riding in the vehicle V, a vehicle position detection step of detecting the position of the vehicle V within a platform P of the waste treatment facility, which has a floor 4, wall 3, ceiling 6, and a drop door 5 to the disposal location, and a projection step of projecting an image onto at least one of the floor 4 and wall 3 to guide the vehicle V to the drop door 5, and switching the image depending on the position of the vehicle. The control unit 50 may perform processing by recording a program for realizing the above-mentioned functions of the control unit 50 (computer) in a computer-readable recording medium, and having the computer read and execute the program recorded in the recording medium. Here, "having the computer read and execute the program recorded in the recording medium" includes installing the program in the computer. The "computer" here includes hardware such as an OS and peripheral devices. The "computer" may also include multiple computer devices connected via a network including communication lines such as the Internet, WAN, LAN, and dedicated lines. The "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, and storage devices such as hard disks built into a computer system. In this way, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM.

[0047] According to the vehicle guidance system 20, vehicle guidance method, and program described above, by utilizing existing facilities and projecting additional images using the projector 10, even if a citizen who does not frequently visit the waste treatment facility comes, the citizen can be automatically guided to the destination and information can be conveyed to him / her. In addition, since the image projected from the projector 10 is projected onto the floor surface 4, the wall surface 3, or the input door 5, the visitor who is the driver of the vehicle can properly recognize the image without having to move his or her line of sight significantly, which increases safety. Furthermore, since audio guidance is provided at the same time as the image, even citizens who do not often visit the waste treatment facility can be automatically guided to their destination and receive information. Furthermore, the destination of the visitor's vehicle is associated with the vehicle's identification information at the reception desk, and the vehicle location detection unit 30 detects the vehicle's location, so the control unit 50 can automatically guide the vehicle to the destination and transmit information. This contributes to labor savings as the facility staff does not need to guide the vehicle, and since people do not approach the vehicle, accidents caused by this can be eliminated.

[0048] Second embodiment Next, a vehicle guidance system 200 in a waste treatment facility according to a second embodiment of the present invention will be described with reference to Fig. 7. The same reference numerals as in the first embodiment are used for configurations similar to those in the first embodiment, and descriptions thereof will be omitted, and only configurations different from the first embodiment will be described.

[0049] 7 is a block diagram showing an example of a vehicle guidance system 200 in a waste treatment facility according to a second embodiment of the present invention. The vehicle guidance system 200 in a waste treatment facility according to the second embodiment of the present invention is different from the vehicle guidance system 20 in a waste treatment facility according to the first embodiment in that the input doors 5 (5a, 5b) used by citizens and the input doors 5 (5c, 5d) used by compactor trucks for business purposes are provided on different platforms P and PP (not shown).

[0050] In this case, if the visitor's attributes are determined to be that of a citizen at the reception desk, the visitor will be guided to platform P where the citizen's input doors 5 (5a, 5b) are located, and if the visitor's attributes are determined to be that of a contractor who has arrived in a compactor truck, the vehicle V will be guided to platform PP where contractor's input doors 5 (5c, 5d) are located.

[0051] The vehicle V guided to the platform P or the platform PP is guided to the input door 5 (5a, 5b) or the input door 5 (5c, 5d) in a manner similar to that of the vehicle guidance system 20 of the first embodiment, so a description thereof will be omitted. That is, as shown in FIG. 7, a vehicle guidance system 20 in a waste treatment facility according to the first embodiment is provided on each of platform P and platform PP, thereby forming a vehicle guidance system 200 in a waste treatment facility according to the second embodiment.

[0052] The vehicle guidance system 200 in a waste treatment facility according to the second embodiment of the present invention as described above can also provide the same effects as those of the first embodiment. In addition, in the explanation of the second embodiment, the vehicle guidance system 200 has been explained, but the same applies to the vehicle guidance method and program. In the second embodiment, the case has been described where the input doors 5 (5a, 5b) used by citizens and the input doors 5 (5c, 5d) used by compactor vehicles for business purposes are provided on different platforms P and PP (not shown), but the platform P for citizens may also receive waste in a yard or container. In the case of such a facility, if the visitor's attribute is determined to be a citizen at the reception desk, the vehicle V may be guided to the front of the yard or container on the platform P for citizens, in the same way as in the first embodiment where the vehicle V was guided to the parking space P in front of the input door 5.

[0053] Example 1 Next, the above embodiment will be described using a more specific example. Note that the present invention is not limited to the following example. In this example, an example in which the vehicle guidance system 20 of the first embodiment is used and multiple vehicles are simultaneously guided to the platform P will be described with reference to Figs. 4 to 6.

[0054] When the destination of the vehicle V1 determined at the reception is the input door 5a, the vehicle V1 is prompted to stop by an image S6 of a blinking rectangular dotted line surrounding a "STOP" traffic sign in front of a stop line near the input door 5a. At the same time as the projection of the image S6, a sound 6 may be output from the speaker 70a. At this time, another vehicle V2 is already parked in the parking space P2 at the input door 5b of the platform P. The word "STOP" (image S7) is projected from the projector 10 onto the floor surface 4 in front of the other vehicle V2 to prevent a collision with the vehicle V1. The projection of the word "STOP" (image S7) displayed on the floor surface 4 in front of the vehicle V2 is stopped when there are no other vehicles stopped before the stop line, when there are other vehicles stopped before the stop line and the word "STOP" (image S6) is being projected, or when the word "PROCEED" (image S8) is not being projected on the floor surface 4 of the parking space P1 of the adjacent input door 5a. Here, the image S6 is not limited to an image of a blinking rectangular dotted line surrounding a "Stop" traffic sign in front of a stop line, but may be the word "Stop" as shown in FIG.

[0055] The vehicle position detection unit 30 detects that the vehicle V1 has stopped before the stop line. When the vehicle position detection unit 30 detects that the vehicle V1 has stopped in front of the stop line, images S1 to S4 guiding the vehicle V1 to the input door 5b are projected onto the floor surface 4. An image of the vehicle V backing up toward the input door 5b may be projected between images S3 and S4.

[0056] The above series of images S1 to S4 are projected when the vehicle V1 is stopped at the stop line (Fig. 4). The driver of the vehicle V1, seeing this, can recognize that he is being prompted to back into the parking space P1 in front of the input door 5a.

[0057] Next, the word "Go" (image S8) is projected from the projector 10 ahead of the stop line (FIG. 5). This allows the driver of the vehicle V1 to execute the actions in the series of images S1 to S4. Simultaneously with the projection of the image S8, the sound 8 may be output from the speaker 70a. Here, simultaneously with the projection of the images S1 to S4, the audio 1 to audio 4 for guiding the vehicle V1 to the parking space in front of the input door 5b may be output from the speaker 70. Furthermore, when the vehicle position detection unit 30 detects that the vehicle V1 has stopped in the parking space in front of the input door 5a, the image S5 may be displayed on the input door 5b, and at the same time, the audio 5 may be output from the speaker 70c.

[0058] When vehicle V1 is permitted to depart from parking space P1 at input door 5a, the word "Go" (image S9) is projected from projector 10 onto floor surface 4 in front of vehicle V1 (FIG. 6). After the word "Go" (image S9) is projected, the visitor starts vehicle V1 and exits through exit 2 of platform P. Simultaneously with the projection of image S9, sound 9 may be output from speaker 70b. Here, vehicle V1 is permitted to depart from the stopping space P1 of the input door 5a when, for example, there is no other vehicle V3 stopped behind the stop line, or when there is another vehicle V3 stopped behind the stop line and the word "STOP" (image S6) is projected onto the floor surface 4 in front of vehicle V3, and the word "STOP" (image S7) is projected in front of another vehicle V2 stopped in the stopping space P2 of the adjacent input door 5b.

[0059] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0060] For example, the loading door 5 (5c, 5d) used by traders who arrive with packer trucks for their work may be provided with a lamp that, as in the past, lights up in a lit color or state to guide the packer truck to the loading door 5 (5c, 5d). The number of projectors 10 may be one or more. The more projectors 10 there are, the larger the area on the platform P onto which the image is projected. In other words, the closer the floor surface 4, wall surface 3, or input door 5 is from the projector 10, the brighter the image can be projected. Therefore, the more projectors 10 there are, the more images with high visibility (images with an illuminance ratio of 2 or more) can be projected onto different locations at a distance on the large platform P. In the example of FIG. 1, projector 10a is suitable for projecting an image near the entrance 1 of the platform P, projector 10b is suitable for projecting an image near the center of the platform P, and projector 10c is suitable for projecting an image onto the input door 5 of the platform P. The number of projectors 10 and their installation locations may be set individually in consideration of the area, ceiling height, etc. of the platform P of the waste treatment facility where the vehicle guidance system 20 and vehicle guidance method according to the above-mentioned embodiment are installed. As an example, it is preferable from the viewpoint of image visibility to arrange the projectors 10 so that the illuminance ratio of the projected image is 2 or more. As with the projectors 10, the more speakers 70 there are, the more easily audible sound can be output to different locations far away on the large platform P. For example, in the example of Fig. 1, speaker 70a is suitable for outputting sound near entrance 1, speaker 70b is suitable for outputting sound near deposit door 5a, and similarly, speakers 70c, 70d, and 70e are suitable for outputting sound near deposit doors 5b, 5c, and 5d. A plurality of vehicle position detection units 30 may also be provided. For example, when the vehicle position detection unit 30 is provided on the floor surface 4, it may be provided individually on the floor surface 4 of each of the stopping spaces P1 to P4 of the input doors 5a, 5b, 5c, and 5d in addition to in front of the stop line near the entrance 1 of the platform P. Alternatively, when the vehicle detection unit 30 is a camera, it may be provided on the ceiling 6 or the wall surface 3. The control unit 50 may be provided in a corner of the platform P as shown in FIG. 1, or may be provided at the reception desk. Depending on the waste treatment facility, in addition to the input door 5, a temporary storage area may be set up on the platform P mainly for waste brought in by citizens, and the waste may be piled up there. For example, an area adjacent to the entrance 1 side of the platform P, as shown in FIG. 1, may be set up as a temporary storage area for waste. In such a facility, if the visitor's attribute is determined to be a citizen at the reception desk, the vehicle V may be guided to the temporary storage area for waste in the same way as the vehicle V was guided to the stopping space P1 in front of the input door 5a in the first embodiment. In other words, the location to which the vehicle V is guided may be set appropriately depending on the waste treatment facility. [Explanation of symbols]
