First Embodiment
Hereinafter, with reference to FIGS. 1 to 4, a first embodiment of a projection apparatus and an automatic door system including the projection apparatus and an automatic door will be described. The projection device of the present embodiment is installed at a position where an image is projected on an automatic door.

  As shown in FIG. 1, the automatic door system includes an automatic door 10 having a door panel (also simply referred to as a door) 11 and a projection device 20 that projects an image on the surface of the door 11. The projection device 20 projects an image on substantially the entire surface of the door 11. The automatic door system is configured such that an image can be projected only on one surface of the door 11, and the projector 20 is installed only on one surface of the door 11. The automatic door system may be configured to project an image on both surfaces of the door 11, and the projection device 20 may be installed on both surfaces of the door 11.

  As shown in FIG. 2, the automatic door 10 includes two movable doors 11, two fixes 12 fixed to the building adjacent to the door 11, and an actuator 18 for moving the door 11. And a door control unit 14 that controls the drive of the door drive unit 13. The fix 12 is a fixed body juxtaposed to the door 11. The door 11 opens the passage when moved to a position facing the fix 12 and closes the passage when not facing the fix 12. The door drive unit 13 drives the motor as an example of the actuator 18 to move the door 11 to a position according to the command of the door control unit 14.

  The door control unit 14 is connected to a door position detection unit 15 that detects the position of the door 11. The door position detection unit 15 includes an encoder (not shown) for detecting the amount of drive of the actuator 18, detects or monitors the position of the door 11 as needed by the encoder, and outputs it to the door control unit 14 as needed. Further, a sensor 16 for detecting an object such as a person located around the door 11 is connected to the door control unit 14. The sensor 16 outputs the detected position of the object to the door control unit 14 together with the detection result of the object located around the door 11. The door control unit 14 causes the door drive unit 13 to open the door 11 or close the door 11 based on the detection result output from the sensor 16. Furthermore, the door control unit 14 is connected to a door communication unit 17 that outputs position information of the door 11 detected by the door position detection unit 15 to the outside. The door communication unit 17 transmits the position of the door 11 input from the door position detection unit 15 as needed. The door communication unit 17 can include, for example, a wireless communication circuit conforming to a short distance wireless communication standard such as Bluetooth (registered trademark).

  The projection device 20 includes a projection unit 21 that projects an image on the surface of the door 11 and a control device 22 that controls the image projected on the surface of the door 11. The control device 22 obtains the position of the door 11 detected by the door position detection unit 15 and the setting unit 23 that sets the position of the door 11 detected by the door position detection unit 15 in the projection unit 21 as the image projection position. And a projection side communication unit 24. The setting unit 23 sets the position of the image projected on the surface of the door 11 by the projection unit 21 and causes the projection unit 21 to project. The image projected by the projection unit 21 includes a bright image and a dark image darker than the bright image. The setting unit 23 sets the position where the door 11 is not present as the door 11 is opened as the position where the dark image is projected. The projection side communication unit 24 acquires the position of the door 11 detected by the door position detection unit 15 from the door control unit 14 of the automatic door 10 and outputs the position to the setting unit 23. The projection side communication unit 24 can include, for example, a wireless communication circuit conforming to a short distance wireless communication standard such as Bluetooth (registered trademark).

  As shown in FIG. 1, the projection unit 21 is a projector that projects an image based on projection data, and is installed on a ceiling or the like of a building in which the automatic door 10 is installed. The projection unit 21 projects an image on the door 11 and the fix 12 of the automatic door 10. Here, assuming that the left side in the figure is the inside of the building and the right side in the figure is the outside of the building, it is assumed that the image projected onto the door 11 is viewed mainly when passersby pass from the outside to the inside of the building The automatic door system is configured such that a passenger can visually recognize the image projected on the door 11 from the rear side of the door 11 from the front side of the door 11. Note that the projection method of the projector can be arbitrarily changed.

  As shown in FIG. 3, the image P projected on the automatic door 10 includes a door image Pa projected on the surface of the door 11, and is projected on the surface of the fix 12 where the door 11 is not located At least one of the image for fixing Pb and the image for passage Pc projected on the area where the door 11 is moved and the door 11 is not located is included. The image P may be a still image or a moving image. The image for door Pa and the image for fixing Pb are bright images that are mainly bright. On the other hand, the passage image Pc is a dark image which is a dark image. Since the image for passage Pc is a dark image, when a passerby of the automatic door 10 passes, the image projected by the projection unit 21 does not feel glare to the passerby. When an image is not necessary for the fix 12 portion, the fix image Pb may be a dark image.

  The image P projected from the projection unit 21 to the automatic door 10 is an image in which the position of the door 11 and the position of the door image Pa are substantially continuously aligned in the temporal space. For example, the images projected on the automatic door 10 are ten different images P1 to P10 in ten different scenes in the range in which the door 11 moves. The positions of the door image Pa in the movement range of the door 11 are different from one another among these ten images P, and the sizes of the image for fixing Pb and the sizes of the image for passage Pc are different accordingly.

  FIG. 3A shows the image P1 when the door 11 is closed. The image P1 does not have the passage image Pc because the door 11 is closed. FIG.3 (b)-(i) have shown the images P2-P9 in case the door 11 is moving. In the images P2 to P9, the size of the fixing image Pb and the size of the passage image Pc change as the position of the door image Pa changes. FIG. 3 (j) shows an image P10 when the door is fully open. The image P10 does not have the fixing image Pb because the door 11 is fully open.

  The setting unit 23 includes an image processing unit for generating projection data. The image for door Pa, the image for fixing Pb, and the image for passage Pc are obtained by the projection processing of the projection unit 21 based on the projection data, and the projection data is generated by clipping from the reference data by the image processing unit.

  The reference data includes data for projecting the door image Pa. Further, the reference data includes data for projecting the image for fixing Pb when the door 11 is closed, and also includes data for projecting the image for passage Pc when the door 11 is vacant. The reference data is data obtained by combining these three data for one frame, and is separately prepared for the right door 11 and the left door 11. The frame represented by the reference data is set larger than the frame represented by the projection data.

  The image processing unit included in the setting unit 23 uses the position of the door 11 detected by the door position detection unit 15 and sets projection data cut out from the reference data so that the door image Pa is positioned on the surface of the door 11 Change the area to the position of the door 11. The image processing unit included in the setting unit 23 combines the projection data cut out for the right door 11 and the projection data cut out for the left door 11, and transfers the synthesized projection data to the projection unit 21. Do.

  For example, the image P1 projected when the door 11 is closed is obtained by the image processing unit performing image processing on the reference data according to the result of the position detection in which the door 11 is at the closed position. At this time, the projection data is cut out from the reference data so that the door image Pa is disposed at the closed position of the door 11 in the frame indicated by the projection data. Also, for example, the image P10 projected when the door 11 is fully opened can be obtained by the image processing unit performing image processing on the reference data according to the result of the position detection in which the door 11 is located at the open position. . At this time, the image processing unit cuts out projection data from the reference data.

  The setting unit 23 may hold projection data for projecting the images P1 to P10 for each image, and may select the projection data in accordance with the position of the door 11. With such a configuration, since the image is determined in advance for each position of the door 11, the processing time required for the image processing of the reference data can be reduced.

  Next, with reference to FIG. 4, the operation of the projection device 20 and the automatic door system configured as described above will be described. Here, operations of the projection device 20 and the automatic door system in the automatic door 10 installed in a building such as a store will be described.

  First, as shown in FIG. 4A, since the door 11 is closed, the position D1 of the closed door 11 is detected by the door position detection unit 15. The automatic door 10 transmits position information of the door 11 from the door communication unit 17. The projection device 20 receives the position information of the door 11 transmitted from the door communication unit 17 via the projection side communication unit 24, and acquires the position information of the door 11. Then, the setting unit 23 of the projection device 20 sets the position D1 of the closed door 11 as the projected position of the door image Pa, based on the acquired positional information of the door 11. In other words, the setting unit 23 prevents the passage image Pc from being disposed in the frame indicated by the projection data such that the door image Pa is disposed at the position D1 of the door 11 in the frame indicated by the projection data. Then, projection data is cut out from the reference data. Then, the projection unit 21 projects the first state image P11 on the position D1 of the door 11. At this time, the first state image P11 projected on the surface of the door 11 is, for example, a still image or a moving image of a person who is being called up with both hands in order to call the customer into a building such as a store.

  Subsequently, as shown in FIG. 4B, when the customer approaches the automatic door 10 and the customer enters a range where the door 11 can be opened, the door 11 is moving toward the position facing the fix 12, and the door The position detection unit 15 detects the position D2 of the door 11 in the middle of movement.

(Other embodiments)
In addition, said each embodiment can also be implemented with the following forms which changed this suitably.
In each of the above-described embodiments, the setting unit 23 may set the plane of the fix 12 in the projection unit 21 as a position on which the bright image is projected. That is, as shown in FIG. 28, the image for door Pa projected on the door 11 and the image for fix Pb projected on the fix 12 are made bright images. In addition, a first image P121, which is an image continuous to the entire door 11 and the fix 12, may be projected. Then, as shown in FIG. 29, when the door 11 is opened, the passage image Pc is projected as a dark image, and the second image P122 which is a continuous image of the left door 11 and the right door 12 is projected. Good. In this way, since the bright image is projected not only on the door 11 but also on the fix 12, the projected area of the bright image can be made larger than that of the door 11 alone, and the visibility can be enhanced.

  In each of the above-described embodiments, the setting unit 23 may set the plane of the fix 12 in the projection unit 21 as the position at which the dark image is projected. That is, as shown in FIG. 30, the third image P123 is projected with the door image Pa projected on the door 11 as the bright image and the fix image Pb projected on the fix 12 as the dark image. In this way, since a dark image is projected on the fix 12, even if a person located in front of the fix 12 looks at the image, it is possible to reduce the glare caused by the projected image. Also, the bright image of the door 11 can be emphasized more.

  In each of the above embodiments, as shown in FIG. 31, the setting unit 23 sets the first fix unit 12a which is a part of the surface of the fix 12 in the projection unit 21 as a position where the bright image is projected, and The second fix unit 12 b other than the first fix unit 12 a may be set in the projection unit 21 as a position on which the dark image is projected on the surface of the fix 12. At this time, the projection unit 21 combines the first fix image Pb which is a bright image projected on the first fix unit 12 a and the second fix image Pd which is a dark image projected on the second fix unit 12 b. The fourth image P124 including the image is projected. In this way, it is possible to emphasize and emphasize the first fix portion 12a on which the bright image is projected more clearly than the second fix portion 12b.

  -Moreover, as shown to FIG. 32 (a)-(c), when the door 11 is fully opened, it is good also as a part which does not oppose the door 11 in the surface of the fix 12 as said 2nd fix part 12b. As shown in FIG. 32C, in the automatic door, a gap C of a predetermined value (for example, 30 mm) or more is provided between the longitudinal end 11c of the door 11 and the cross 12c of the fix 12 when fully open. There is a portion that does not face the door 11 in the plane of the fix 12 when fully open. By setting the second fix portion 12b in this manner, a bright image is projected on the existing position of the door 11 from the fully closed time (FIG. 32 (a)) to the fully open time (FIG. 32 (c)) of the door 11. Can be set as the

  In each of the above-described embodiments, at least a part of the surface of the fix 12 may include a color unit that suppresses the reflection of light from the projection unit 21. The color portion is a film or sheet made of a material that suppresses the reflection of light, and is attached to a portion that the projected image is not desired to be viewed by a passerby or the like. For example, a color portion is provided in the second fix portion 12b described above. In this way, it is possible to prevent a passerby from being visually recognized by the color section even if the projected image is a bright image, without setting the projected image as a dark image. In addition, the color part may be provided in the fix 12 by the material which suppresses reflection of light not in a film or a sheet but in the glass etc. which comprise the fix 12.

  In each of the above embodiments, as shown in FIG. 33, the setting unit 23 sets the first portion 11 a which is a part of the surface of the door 11 in the projection unit 21 as a position where the bright image is projected. In the plane, the second unit 11b other than the first unit 11a may be set in the projection unit 21 as a position at which the dark image is projected. For example, a portion of the door butt longitudinal stile of the door 11 may be used as the second portion 11 b. At this time, the projection unit 21 projects a fifth image P125 including the door image Pa, which is a bright image projected onto the first unit 11a, and the second door image Pe projected onto the second unit 11b. . Further, the image for fixation Pb, which is a dark image, is projected to the fixation 12. In this way, the bright image is projected on the first portion 11a of the door 11, and the dark image is projected on the second portion 11b of the door 11. Thus, the first portion 11a on which the bright image is projected is It can be emphasized and emphasized more than the part 11b.

  In each of the above-described embodiments, at least a part of the surface of the door 11 may include a color unit that suppresses the reflection of light from the projection unit 21. This color portion is a film or sheet made of a material that suppresses the reflection of light, and is attached to the portion of the door 11 that the projected image is not desired to be viewed by a passerby or the like. In this way, the projected image is a bright image without setting the projected image as a dark image, since the projected image can not be viewed on a part of the surface of the door 11. Even with the color section, it is possible to prevent a passerby from being visible. In addition, the color part may be provided in the door 11 by the material which suppresses reflection of light not being a film or a sheet | seat but glass etc. which comprise the door 11 is included. For example, a color portion may be provided in the portion of the longitudinal edge of the door 11 at the buttocks.

  In each of the above-described embodiments, the setting unit 23 may set a part of the surface of the door 11 in the projection unit 21 as a position where the image is not projected. For example, the image itself is not projected on the second part 11b of FIG. In this way, since the image is not projected onto the part set in part of the surface of the door 11, glare can be reduced in part of the surface of the door 11.

  In addition, as shown in FIG. 34, the setting unit 23 sets the first portion 11a which is a part of the surface of the door 11 in the projection portion 21 as a position on which the bright image is projected. The second unit 11b other than the unit 11a may be set in the projection unit 21 as a position at which a dark image is projected. The first portion 11 a corresponds to the central portion of the two connected doors 11. At this time, the projection unit 21 projects a sixth image P126 including the door image Pa, which is a bright image projected onto the first unit 11a, and the second door image Pe projected onto the second unit 11b. . In this way, the bright image is projected on the first portion 11a of the door 11, and the dark image is projected on the second portion 11b of the door 11. Thus, the first portion 11a on which the bright image is projected is It can be emphasized and emphasized more than the part 11b.

  In the above embodiments, the setting unit 23 may set a part of the surface of the fix 12 in the projection unit 21 as a position where the image is not projected. For example, as shown in FIG. 35, the first fix portion 12a other than the second fix portion 12b is a position where the second fix portion 12b which is a portion not facing the door 11 on the surface of the fix 12 when the door 11 is fully opened is not projected. And the door 11 may be the projection range R. In this way, since the image is not projected on a part of the surface of the fix 12 (the second fix portion 12 b), glare can be reduced on a part of the surface of the fix 12. In addition, the position where the door 11 is present from the time when the door 11 is fully closed to the time when the door 11 is fully open can be set as a range where the image is projected.

  In each of the above embodiments, as shown in FIG. 36, the projection unit 21 includes the projection unit 21a including the surface of the fix 12 and the surface of the door 11 as the projection target, and at least a part of the surface of the fix 12. You may provide with the shielding part 21b comprised so that shielding by the projection by the light projection part 21a was possible. According to this configuration, since the shielding unit 21b that shields the projection is provided in the projection unit 21, the shielding unit 21b does not set the projected image as a dark image, and the shielding unit 21b can display even if the projected image is a bright image. Glare can be reduced by shielding.

You may cut out. That is, the image processing unit included in the setting unit 23 performs clipping for the right side such that the door image Pa is positioned on the surface of the right door 11 with respect to one reference data, and for the same reference data. The cutout for the left side may be performed so that the door image Pa is positioned on the surface of the left door 11. In such a configuration, the image projected on the right door 11 and the image projected on the left door 11 are originally obtained from one reference data, and thus are projected on the right door 11 It is possible to enhance the symmetry and unity between the image and the image projected on the left door 11.

  In each of the above embodiments, the setting unit 23 separately holds the reference data for the door image Pa, the reference data for the fix image Pb, and the reference data for the passage image Pc. The projection data for the right side may be generated by combining the projection data cut out from. Similarly, the setting unit 23 separately holds reference data for the door image Pa, reference data for the fix image Pb, and reference data for the passage image Pc, and is cut out from each reference data. Projection data for the left side may be generated by combining the projection data.

  As described in the above modification, in a configuration in which projection data for these three images are cut out from one reference data, for example, a character included in the door image Pa and a character included in the fix image Pb. The relative position is predetermined in one reference data. In other words, in the configuration in which projection data for these three images are cut out from one reference data, the relative position between characters included in each image is determined in the reference data. Therefore, while fixing the position of the character included in the door image Pa with respect to the door 11, it is difficult to change the position of the character included in the fixing image Pb.

  On the other hand, as described above, in a configuration in which projection data for three images is cut out from separate reference data, for example, the relative between the character included in the image for door Pa and the character included in the image for fix Pb. Location is defined between different reference data. Therefore, while fixing the position of the character included in the door image Pa with respect to the door 11, it is also easy to change the position of the character included in the fixing image Pb.
