FIG. 5A is a diagram illustrating an example of a captured image of the camera 8, and FIG. 5B is a diagram illustrating an example of a captured image when an occupant is seated on the rear seat 120.
As shown to (a) of FIG. 5, the seat cushion 121 and the seat back 122 of the rear seat 120, and the seat cover C which covers each are reflected in the picked-up image of the camera 8. Further, as shown in FIG. 5B, if the occupant P is seated on the rear seat 120, the occupant P appears in the captured image.

FIG. 6 is a block diagram showing a configuration of the control device 7.
As shown in FIG. 6, the camera 8 is connected to the control device 7, and the camera 8 sequentially inputs the captured images of each frame to the control device 7.
The control device 7 controls the operations of the first winding unit 3 and the second winding unit 5 based on the captured image of the camera 8. The control device 7 controls the first winding unit 3 and the second winding unit 5 to control the seat when the dirt of the seat cover C covering the rear seat 120 is detected at a timing when the occupant P is not seated on the rear seat 120. The cover C is wound up, and the dirty sheet cover C is replaced with a new one.

  The control device 7 includes, for example, a memory such as a CPU (Central Processing Unit), a RAM (Random Access Memory) and a ROM (Read Only Memory), a timer, an input / output interface, an inter-computer communication unit, and the like. The functions of each unit shown in FIG. 6 are realized by the CPU executing various applications stored in the memory. The memory stores various types of information necessary for the processing of the control device 7 and temporarily stores the processing results of the respective units.

The control device 7 exchanges data with each of the drive motors 37 and 57 of the camera 8, the roller 32, and the roller 52 through communication such as in-vehicle LAN.
As shown in FIG. 6, the control device 7 includes an occupant detection unit 71, a dirt detection unit 72, and a motor control unit 73.

  The occupant detection unit 71 performs image processing on the captured image of the camera 8 and detects the occupant P seated on the rear seat 120. The occupant detection unit 71 detects the occupant P at a predetermined interval, and inputs the detection result to the dirt detection unit 72. The predetermined interval is not particularly limited, but can be, for example, every 5 minutes.

  When the occupant detection unit 71 does not detect the occupant P, the dirt detection unit 72 performs image processing on the captured image, and detects the contamination of the seat cover C that covers the seat cushion 121 and the seat back 122 of the rear seat 120. The dirt is, for example, dust dirt GS such as paper waste or food waste shown in FIG. 1, FIG. 2 and FIG.

  A well-known method can be used for the detection of the occupant P in the occupant detection unit 71 and the detection of the contamination in the contamination detection unit 72. For example, a feature amount extraction method may be used in which a target is detected based on the similarity between the feature amount calculated from the captured image and the feature amount calculated from the comparison image. Furthermore, detection accuracy can be improved by using, for example, a machine learning or deep learning method.

  As described above, since the seat cover C includes the water discoloring material, the seat cover C changes color when water is spilled. Therefore, the stain detection unit 72 detects the wet stain WS by detecting the discolored portion of the sheet cover C.

  The motor control unit 73 drives the drive motors 37 and 57 when the dirt detection unit 72 detects the dirt on the rear seat 120.

  When the dirt detection unit 72 detects the dirt on the seat cover C that covers the seat cushion 121, the motor control unit 73 drives the drive motor 37 of the roller 32 of the first winding unit 3 to rotate the rotating shaft 36. Let By rotating the rotation shaft 36 of the roller 32, the seat cover C covering the upper surface 121 a of the seat cushion 121 is wound on the rotation shaft 36. At the same time, the roller 31 is also rotated by the tension of the seat cover C, and the seat cover C wound around the rotating shaft 34 is sent out onto the upper surface 121 a of the seat cushion 121.

  The motor control unit 73 controls the amount of rotation of the rotary shaft 36, winds up the seat cover C by at least the length corresponding to the length from the front end to the rear end of the seat cushion 121, and detects the dirt. Replace with a new one.

  When the dirt detection unit 72 detects the dirt on the seat cover C that covers the seat back 122, the motor control unit 73 drives the drive motor 57 of the roller 52 to rotate the rotating shaft 56. As the rotation shaft 56 of the roller 52 rotates, the sheet cover C covering the front surface 122 a of the seat back 122 is wound on the roller 52. At the same time, the roller 51 is also rotated by the tension of the seat cover C, and the sheet cover C wound around the rotating shaft 54 is sent out onto the front surface 122 a of the seat back 122.

  The motor control unit 73 controls the amount of rotation of the rotary shaft 56, winds up the seat cover C at least by the length corresponding to the length from the lower end to the upper end of the seat back 122, and removes the seat cover C from which dirt has been detected. Replace with a new one.

  The camera 8 and the control device 7 are not limited to the control of the operation of the take-up device for the seat cover C, and may be used for other purposes. For example, a monitor may be installed on a dashboard in the passenger compartment 100, and the control device 7 may perform display control for displaying a captured image of the camera 8 on the monitor.

[Operation]
The operation of the seat cover winding device 1 will be described together with a usage example.
The seat cover retractor 1 can be used, for example, in a vehicle such as a taxi that travels unattended.

  The vehicle puts the occupant P on the vehicle at the taxi stand or the designated place of the occupant P, travels to the destination of the occupant P, and drops the occupant P from the vehicle. After the occupant P is unloaded, the vehicle travels to the nearest taxi stand or the like to place another occupant P.

The occupant P sits on the rear seat 120 of the vehicle (see FIG. 5B), but the occupant P sits in a wet state, or an infant or the like spills food or drink, and the dirt GS or wet Dirt WS may occur (see FIG. 5A).
Since the rear seat 120 is covered with the seat cover C, the rear seat 120 itself can be prevented from being dirty, but the seat cover C is in a dirty state.

  If the next occupant P gets into the vehicle while the seat cover C is still dirty, there is a possibility that unpleasant feeling is given. The seat cover winding device 1 according to the embodiment winds and sends out the seat cover C when the occupant P detects that the seat cover C is dirty at a timing when the occupant P is not seated on the rear seat 120. Replace C.

FIG. 7 is a flowchart showing the operation of the sheet cover winding device 1.
When the vehicle starts driving, the camera 8 starts capturing images and sequentially inputs the captured images to the control device 7.
The occupant detection unit 71 acquires the latest input captured image at predetermined intervals, performs image processing, and detects the occupant P seated on the rear seat 120 (step S01).

If the occupant detection unit 71 detects the occupant P seated on the rear seat 120 (step S01: Yes), the process proceeds to step S04 because it is not time to replace the seat cover C.
If the occupant detection unit 71 does not detect the occupant P seated on the rear seat 120 (step S01: No), the dirt detection unit 72 performs image processing on the captured image and detects the dirt on the seat cover C that covers the rear seat 120. (Step S02).

  When the dirt detection unit 72 does not detect the dirt on the sheet cover C (step S02: No), the process proceeds to step S04.

  When the dirt detection unit 72 detects the dirt on the sheet cover C (step S02: Yes), the motor control unit 73 drives the drive motors 37 and 57 (step S03) to wind up the sheet cover C. .

  Here, when the dirt detection unit 72 detects the dirt on the seat cover C that covers the seat cushion 121, the motor control unit 73 drives the drive motor 37 of the first winding unit 3. The rotation shaft 36 of the roller 32 is rotated by driving of the drive motor 37 and the seat cover C covering the seat cushion 121 is wound up. When the dirt detection unit 72 detects the dirt on the seat cover C that covers the seat back 122, the motor control unit 73 drives the drive motor 57 of the second winding unit 5. The rotation shaft 56 of the roller 52 is rotated by driving of the drive motor 57 and the sheet cover C covering the seat back 122 is wound up.

  When the dirt detection unit 72 detects the dirt of the seat cover C in both the seat cushion 121 and the seat back 122, the motor control unit 73 drives the drive motors of the first winding unit 3 and the second winding unit 5. Both 57 are driven.

  Thereafter, the process is continued while the vehicle is driving (step S04: Yes), and the process returns to step S01 to repeat the process.

As described above, the sheet cover winding device 1 according to the embodiment is
(1) A roller 31 that is disposed on one end side of the seat cushion 121 and the seat back 122 (seat) of the rear seat 120 in the passenger compartment 100 and feeds the seat cover C covering the seat cushion 121 and the seat back 122 onto the rear seat 120, 51 (delivery part),

Drive motors 37 and 57 (drive sources) for rotating the rollers 32 and 52.

  By covering the rear seat 120 of the vehicle with the seat cover C, the rear seat 120 can be prevented from being soiled. However, conventionally, when the seat cover C itself becomes dirty, it is troublesome to wipe the wet dirt WS with a cloth, suck out the dust dirt GS with a vacuum cleaner, or remove the seat cover C and replace it with a new one. It was necessary to work.

  According to the sheet cover take-up device 1 of the embodiment, the drive motors 37 and 57 are driven to take up the dirty sheet cover C with the rollers 32 and 52, and simultaneously send out a new sheet cover C from the rollers 31 and 51. be able to. As a result, the seat cover C can be easily replaced, and the convenience of the vehicle occupant P can be improved.

(2) The sheet cover winding device 1 is disposed below the rollers 32 and 52 on the other end side of the rear sheet 120, and stores a dust storage tray that stores the dust G falling from the sheet cover C wound around the rollers 32 and 52. 9 (accommodating part).

  In a vehicle such as a taxi that travels unattended, even if the seat cover C gets dirty when a certain occupant P gets in, the seat cover C cannot be manually cleaned or replaced because there is no driver. If the next occupant P gets into the vehicle while the seat cover C is dirty, the occupant P may be uncomfortable.

  By detecting the occupant P sitting on the rear seat 120 from the photographed image of the camera 8, the seat cover C can be automatically wound at the timing when the occupant P is not seated on the rear seat 120. As a result, the occupant P can sit on the clean seat cover C, and the convenience of the occupant P can be improved.

(4) The seat cover winding device 1 includes a dirt detection unit 72 that detects dirt on the seat cover C that covers the seat cushion 121 and the seat back 122 using an image captured by the camera 8.
When the dirt detector 72 detects dirt, the drive motors 37 and 57 are driven to wind the seat cover C covering the seat cushion 121 and the seat back 122 around the rollers 32 and 52.

  By taking up the sheet cover C when dust dirt GS or wet dirt WS or the like is detected from the photographed image of the camera 8, the number of replacements of the sheet cover C can be reduced while keeping the sheet cover C clean. It is possible to improve economy.

(5) The seat cover C is configured to include a water-coloring material that changes color in a water-containing state,
When the stain detection unit 72 detects a discolored portion of the seat cover C covering the seat cushion 121 and the seat back 122 from the image taken by the camera 8, the dirt detection unit 72 drives the drive motors 37 and 57 to drive the seat cushion 121 and the seat. The sheet cover C covering the back 122 is wound around the rollers 32 and 52.

  When the wet stain WS due to water is colorless and transparent, it is difficult to detect from the photographed image. However, since the seat cover C is made of a water discoloring material, a discoloration portion is generated in the sheet cover C due to the wet stain WS. It becomes easy to detect.
