For ease of understanding, the same components in the following embodiments are illustrated with the same symbols.

[0032] See also Figure 1 and Figure 2, which is a block diagram and schematic diagram of the banquet venue interactive light and shadow projection system of the first embodiment of the utility model. As shown in the figure, the banquet venue interactive light and shadow projection system 1 includes a storage device 11, a light and shadow content generation module 12 and a projector 13. The banquet venue interactive light and shadow projection system 1 can be applied to various banquet venues. The "banquet venue" described in this specification generally refers to weddings, award ceremonies, film exhibitions, fashion shows, charity parties, etc., but is not limited to this.

[0033] The storage device 11 stores a plurality of light and shadow objects. The plurality of light and shadow objects may be various patterns, such as flowers, insects, animals, fruits, buildings, and geometric shapes, etc. In one embodiment, the storage device 11 may be a hard disk, various computers, a cloud storage device, etc.

[0034] The light and shadow content generation module 12 captures an image of a predetermined carpet area PS of the banquet venue, and selects one or more of the plurality of light and shadow objects 111 to obtain a plurality of selected light and shadow objects 121, and generates a light and shadow carpet image 122 that matches the surface visual features of the image of the predetermined carpet area PS of the banquet venue and the plurality of selected light and shadow objects 121. The predetermined carpet area PS may be a floor or a floor with a carpet. In one embodiment, the light and shadow content generation module 12 may be a personal computer, a laptop computer, a workstation, a server, or other similar devices.

[0035] The projector 13 projects the light and shadow carpet image 122 onto the predetermined carpet area PS, so that the predetermined carpet area PS produces a mixed virtual and real visual effect.

[0036] As can be seen from the above, the banquet venue interactive light and shadow projection system 1 can generate a light and shadow carpet image 122 that matches the predetermined carpet area PS according to the above-mentioned multiple selected light and shadow objects 121 through the light mapping technology to generate a dazzling and vivid light and shadow carpet image 122. Among them, the light and shadow content generation module 12 can first capture and store the image of the predetermined carpet area PS of the banquet venue, which has a surface visual feature; this surface visual feature can include the surface texture of the predetermined carpet area PS. Then, the light and shadow content generation module 12 can perform texture special effects processing, superimposing color block elements, particles and other visual effects on the surface texture of the predetermined carpet area PS. Next, the light and shadow content generation module 12 can perform shadow special effects processing, adding shadow special effects to the surface texture of the predetermined carpet area PS, so that it presents a three-dimensional visual effect. Finally, the light and shadow content generation module 12 can perform color special effects processing, filling the surface texture of the predetermined carpet area PS with appropriate colors, so that it can achieve vivid color changes. Through the various special effects processing described above, the light and shadow content generation module 12 can generate a light and shadow carpet image 122 that matches and blends with the predetermined carpet area PS according to the multiple selected light and shadow objects 121, which can have virtual-real mixed projection effects such as color block elements, particle dynamics, shadow changes, three-dimensional visual effects, and vivid color changes. In this way, the light and shadow carpet image 122 can blend with the texture of the carpet itself to produce a virtual-real mixed projection effect. Therefore, the banquet venue interactive light and shadow projection system 1 can generate a light and shadow carpet image 122 with rich visual effects to achieve a perfect combination of the light and shadow carpet image 122 and the space.

[0037] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the banquet venue interactive light and shadow projection system 1 according to this embodiment should still be included in the patent scope of the present invention.

[0038] See also Figure 3 , which is a block diagram of the banquet venue interactive light and shadow projection system of the second embodiment of the utility model, and please also refer to Figure 2 As shown in the figure, the banquet venue interactive light and shadow projection system 1 includes a storage device 11 , a light and shadow content generating module 12 and a projector 13 .

[0039] The above components are similar to the above embodiments, so they will not be described in detail here. Different from the above embodiments, the banquet venue interactive light and shadow projection system 1 further includes a motion detection module 14. The motion detection module 14 detects the target object BT (such as Figure 2As shown, the target object BT of this embodiment is a bride, but it is not limited to this; in another embodiment, the target object BT may also be a groom or other important person). The light and shadow content generation module 12 adjusts the light and shadow carpet image 122 according to the motion information so that the light and shadow carpet image 122 interacts with the target object BT. In this embodiment, the motion information may be gait and / or speed. The motion detection module 14 detects the gait and / or speed of the target object BT to generate a motion detection result 141. Then, the light and shadow content generation module 12 adjusts multiple light and shadow parameters of the light and shadow carpet image 122 according to the motion detection result 141. For example, the above-mentioned multiple light and shadow parameters may include but are not limited to one or more of the color, brightness, size, pattern and moving speed of the light and shadow carpet image 122. In one embodiment, the motion detection module 14 may be an infrared sensor, a 3D scanning device, an image recognition system capable of performing motion detection, etc.

[0040] For example, when the gait of the target object BT is slow, the light and shadow content generation module 12 adjusts the color of the light and shadow carpet image 122 according to the motion detection result 141, so that it changes from light to dark (or from dark to light) at a slower speed. Conversely, when the gait of the target object BT is fast, the light and shadow content generation module 12 adjusts the color of the light and shadow carpet image 122 according to the motion detection result 141, so that it changes from light to dark (or from dark to light) at a faster speed. Similarly, the light and shadow content generation module 12 can also adjust the brightness of the light and shadow carpet image 122 according to the gait of the target object BT, so that it changes from light to dark (or from dark to light) at a speed corresponding to the gait of the target object BT. The light and shadow content generation module 12 can also adjust the size or pattern of the light and shadow carpet image 122 according to the gait of the target object BT, so that it changes at a speed corresponding to the gait of the target object BT. In another embodiment, when the target object BT has a fast gait, the light and shadow content generating module 12 adjusts the moving speed of the selected light and shadow object 121 of the light and shadow carpet image 122 according to the motion detection result 141 so that it moves with the target object BT, thereby generating a vivid and interactive visual effect.

[0041] As can be seen from the above, in this embodiment, the banquet venue interactive light and shadow projection system 1 has a motion detection module 14. The motion detection module 14 can detect the gait and / or speed of the target object BT to generate a motion detection result 141. The light and shadow content generation module 12 adjusts multiple light and shadow parameters of the light and shadow carpet image 122 according to the motion detection result 141, such as one or more of color, brightness, size, pattern and moving speed. Therefore, the banquet venue interactive light and shadow projection system 1 can generate a light and shadow carpet image 122 that can interact with the target object BT, so that the light and shadow carpet image 122 can achieve an interactive visual effect to produce an eye-catching visual effect.

[0042] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the banquet venue interactive light and shadow projection system 1 according to this embodiment should still be included in the patent scope of the present invention.

[0043] See also Figure 4 , Figure 5 and Figure 6 . Figure 4 It is a block diagram of an interactive light and shadow projection system for a banquet venue according to a third embodiment of the utility model. Figure 5 and Figure 6 The first and second schematic diagrams are respectively the interactive light and shadow projection system for banquet venues of the third embodiment of the utility model. Figure 4 As shown, the banquet venue interactive light and shadow projection system 1 includes a storage device 11 , a light and shadow content generating module 12 , a projector 13 and a motion detecting module 14 .

[0044] The above components are similar to the above embodiments, so they will not be described in detail here. Different from the above embodiments, the banquet venue interactive light and shadow projection system 1 further includes a motion trajectory tracking module 15. The motion trajectory tracking module 15 can detect the target object BT to calculate the offset 151 of the detected target object BT relative to the predetermined carpet area PS, and control the projector 13 according to the above offset 151 to adjust the light and shadow carpet image 122. In one embodiment, the motion trajectory tracking module 15 can be a combination of a camera and a computing device. The computing device can be, but is not limited to, a central processing unit, a special application integrated circuit chip, etc.

[0045] In this embodiment, the movement trajectory tracking module 15 detects the first feature point P1 of the left foot of the target object BT and the second feature point P2 of the right foot of the target object BT. The first feature point P1 and the second feature point P2 are points that can represent the movement direction of the left foot and the right foot of the target object BT respectively; for example, the first feature point P1 and the second feature point P2 can be the toes of the left foot and the toes of the right foot respectively. Then, the movement trajectory tracking module 15 calculates the reference point P0 between the first feature point P1 and the second feature point P2 when the time interval between the first feature point P1 and the second feature point P2 is within the preset time interval. The aforementioned preset distance can be the average distance of a person's stride when walking (such as 10 cm to 25 cm), which can be appropriately adjusted according to various information such as the gender and age of the target object BT. Since there is a short period of time when a person walks with both feet on the ground at the same time, this time interval can be the aforementioned preset time interval (such as 0.1 seconds to 0.5 seconds), which can also be appropriately adjusted according to various information such as the gender and age of the target object BT. When the above conditions are met (the first feature point P1 and the second feature point P2 are at a preset distance, and the time interval between the first feature point P1 and the second feature point P2 and the preset distance is within the preset time interval), the moving trajectory tracking module 15 can calculate the reference point P0 between the first feature point P1 and the second feature point P2; the reference point P0 can be the midpoint between the first feature point P1 and the second feature point P2. Then, the moving trajectory tracking module 15 calculates the offset 151 between the reference point P0 and the preset trajectory line L1 of the predetermined carpet area PS; the preset trajectory line L1 can be the center line of the predetermined carpet area PS (this center line can cut the predetermined carpet area PS into two parts of equal area), but is not limited thereto. In another embodiment, the preset trajectory line L1 can also be a straight line parallel to the center line of the predetermined carpet area PS. Finally, the moving trajectory tracking module 15 controls the projector 13 according to the offset to appropriately move the light and shadow carpet image 122 so that the light and shadow carpet image 122 can move with the target object BT. In another embodiment, the first characteristic point P1 and the second characteristic point P2 may be the heel of the left foot and the heel of the right foot, respectively. In yet another embodiment, the first characteristic point P1 and the second characteristic point P2 may be further adjusted according to actual needs.

[0046] like Figure 5 As shown, the movement trajectory tracking module 15 can calculate the offset 151 between the reference point P0 and the preset trajectory line L1 of the predetermined carpet area PS as 0 through the above mechanism. At this time, the movement trajectory tracking module 15 controls the projector 13 to keep the light and shadow carpet image 122 from moving left or right.

[0047] like Figure 6As shown, the movement trajectory tracking module 15 can calculate the offset 151 between the reference point P0 and the preset trajectory line L1 of the predetermined carpet area PS as the distance D1 through the above mechanism. At this time, the movement trajectory tracking module 15 controls the projector 13 to keep the light and shadow carpet image 122 moving to the left. In this way, the light and shadow carpet image 122 can move with the target object BT.

[0048] As can be seen from the above, the banquet venue interactive light and shadow projection system 1 has a moving trajectory tracking module 15. The moving trajectory tracking module 15 detects the offset 151 between the moving trajectory of the target object BT and the preset trajectory line of the predetermined carpet area PS, and adjusts the light and shadow carpet image 122 according to the offset. Therefore, the light and shadow carpet image 122 can change with the moving trajectory of the target object BT to further enhance the interactive visual effect of the light and shadow carpet image 122.

[0049] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the banquet venue interactive light and shadow projection system 1 according to this embodiment should still be included in the patent scope of the present invention.

[0050] It is worth mentioning that the carpets in existing banquet venues are usually relatively simple and cannot provide any special effects. Existing lighting equipment cannot effectively produce special effects suitable for carpets to achieve a perfect combination with space. On the contrary, according to an embodiment of the utility model, the interactive light and shadow projection system of the banquet venue includes a storage device, a light and shadow content generation module and a projector. The storage device stores a plurality of light and shadow objects. The light and shadow content generation module captures the image of the predetermined carpet area of ​​the banquet venue, and selects one or more of the above-mentioned multiple light and shadow objects to obtain a plurality of selected light and shadow objects, and generates a light and shadow carpet image matching the surface visual features according to the surface visual features of the image of the predetermined carpet area of ​​the banquet venue and the above-mentioned multiple selected light and shadow objects. The projector projects the light and shadow carpet image to the predetermined carpet area, so that the predetermined carpet area produces a mixed light and shadow carpet visual effect. Therefore, the interactive light and shadow projection system of the banquet venue can produce a dazzling and vivid light and shadow carpet image to replace the existing carpet, and combine it with the surface visual features of the predetermined carpet area. Therefore, the interactive light and shadow projection system of the banquet venue can produce a light and shadow carpet image with rich visual effects to achieve a perfect combination of the light and shadow carpet image and the space.

[0051] Furthermore, according to an embodiment of the utility model, the banquet venue interactive light and shadow projection system has a motion detection module. The motion detection module can detect the gait and / or speed of the target object to generate a motion detection result. The light and shadow content generation module adjusts multiple light and shadow parameters of the light and shadow carpet image according to the motion detection result, such as one or more of color, brightness, size, pattern and moving speed. Therefore, the banquet venue interactive light and shadow projection system can generate a light and shadow carpet image with interactive visual effects, so that the light and shadow carpet image can achieve a more eye-catching visual effect.

[0052] In addition, according to an embodiment of the present invention, the interactive light and shadow projection system for a banquet venue has a moving trajectory tracking module. The moving trajectory tracking module detects the offset between the moving trajectory of the target object and the preset trajectory line of the predetermined carpet area, and adjusts the light and shadow carpet image according to the offset. Therefore, the light and shadow carpet image can change with the moving trajectory of the target object to further enhance the interactive visual effect of the light and shadow carpet image. From the above, it can be seen that the interactive light and shadow projection system for a banquet venue according to an embodiment of the present invention can indeed achieve excellent technical effects.

[0053] See also Figure 7 , which is a block diagram of the banquet venue interactive light and shadow projection system of the fourth embodiment of the utility model, and please also refer to Figure 2 As shown in the figure, the banquet venue interactive light and shadow projection system 1 includes a storage device 11 , a light and shadow content generating module 12 , a projector 13 , a motion detecting module 14 and a moving track tracking module 15 .

[0054] The above components are similar to the above embodiments, so they will not be described in detail here. Unlike the above embodiments, the banquet venue interactive light and shadow projection system 1 further includes an artificial intelligence module 16. The artificial intelligence module 16 can analyze the personal information 161 of the target object BT, and the light and shadow content generation module 12 selects one or more of the above multiple light and shadow objects 111 according to the personal information to obtain the above multiple selected light and shadow objects 121. The personal information 161 of the target object BT may include but is not limited to gender, race, age, etc. Therefore, the artificial intelligence module 16 can infer the preferences of the target object BT based on the personal information 161 of the target object BT, so that the light and shadow content generation module 12 can find the above multiple selected light and shadow objects 121 that are more likely to meet the preferences of the target object BT from the above multiple light and shadow objects 111. Through the above mechanism, the light and shadow content generation module 12 can generate a light and shadow carpet image 122 that is more in line with the preferences of the target object BT.

[0055] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the banquet venue interactive light and shadow projection system 1 according to this embodiment should still be included in the patent scope of the present invention.

[0056] See also Figure 8 , which is a block diagram of the banquet venue interactive light and shadow projection system of the fifth embodiment of the present invention, and please also refer to Figure 2 As shown in the figure, the banquet venue interactive light and shadow projection system 1 includes a storage device 11 , a light and shadow content generating module 12 , a projector 13 , a motion detecting module 14 , a moving track tracking module 15 and an artificial intelligence module 16 .

[0057] The above components are similar to the above embodiments, so they are not described in detail here. Unlike the above embodiments, the interactive light and shadow projection system 1 for banquet venues further includes a cloud server 17. In addition, the user can interact with the interactive light and shadow projection system 1 for banquet venues through the electronic device ED. The above electronic device ED can be a smart phone, a smart watch, a tablet computer, a laptop computer, a personal computer, etc. By installing a corresponding application on the electronic device ED, the user can send an operation instruction Ls to the light and shadow content generation module 12 through the electronic device ED to select one or more of the above multiple light and shadow objects 111 in the storage device 11 to generate the above multiple selected light and shadow objects 121. In addition, the user can also upload the light and shadow objects 111 that meet the user's preferences to the light and shadow content generation module 12 as the above multiple selected light and shadow objects 121. On the other hand, the user can also send the operation instruction Ls to the light and shadow content generation module 12 by operating the application of the electronic device ED to change the color and size of the above multiple selected light and shadow objects 121, or make some personalized adjustments.

[0058] At the same time, the light and shadow content generation module 12 also transmits the user's operation instruction Ls to the cloud server 17. Then, the cloud server 17 can store each user's operation instruction Ls, gender, race, age and other personal information, and perform big data analysis. In this way, the cloud server 17 can provide various special recommendation schemes after a period of time and transmit them to the light and shadow content generation module 12. For example, the cloud server 17 can provide a combination of light and shadow objects or a light and shadow carpet image 122 that conforms to the user's gender, race, and age as a recommendation scheme based on the user's personal information. For example, the light and shadow content generation module 12 can also provide the most popular light and shadow object combination or light and shadow carpet image 122 as a recommendation scheme. In this way, when the user interacts with the banquet venue interactive light and shadow projection system 1 through the electronic device ED, he can directly choose from the above-mentioned recommendation schemes.

[0059] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the banquet venue interactive light and shadow projection system 1 according to this embodiment should still be included in the patent scope of the present invention.

[0060] In summary, according to an embodiment of the utility model, the interactive light and shadow projection system for a banquet venue includes a storage device, a light and shadow content generation module and a projector. The storage device stores a plurality of light and shadow objects. The light and shadow content generation module captures an image of a predetermined carpet area of ​​the banquet venue, and selects one or more of the plurality of light and shadow objects to obtain a plurality of selected light and shadow objects, and generates a light and shadow carpet image matching the surface visual features according to the surface visual features of the image of the predetermined carpet area of ​​the banquet venue and the plurality of selected light and shadow objects. The projector projects the light and shadow carpet image to the predetermined carpet area, so that the predetermined carpet area produces a mixed light and shadow carpet visual effect. Therefore, the interactive light and shadow projection system for a banquet venue can produce a dazzling and vivid light and shadow carpet image to replace the existing carpet, and combine it with the surface visual features of the predetermined carpet area.
