Description

Technical Field

[0001] The present application relates to the field of lighting control technology, and in particular to an intelligent light and shadow interactive lighting control system based on dynamic perception. Background Art

[0002] Currently, dynamic perception is the ability to gain insight into security risks in a dynamic, holistic, and environmentally-based manner. It monitors, analyzes, and understands various data in the environment in real time to understand the current state, development trends, and potential threats or opportunities, and to make appropriate responses or decisions accordingly. As a key technology, dynamic perception has demonstrated significant application potential in a variety of fields, including cybersecurity, robotics, and autonomous driving. Interactive light and shadow projection can provide participants with an extraordinary visual experience. It differs significantly from ordinary projection methods in that it uses multi-channel projection fusion technology to project images onto large or multi-sided projection screens. Through intelligent control via an interactive sensing system, it can interact with the audience. Therefore, interactive light and shadow lighting control based on dynamic perception is crucial to the participant's experience.

[0003] The existing intelligent light and shadow interactive lighting control based on dynamic perception is that the audience touches the virtual chime interface, the system senses and identifies the touch position, triggers the corresponding sound effect and plays it. However, the existing intelligent light and shadow interactive lighting control based on dynamic perception does not take into account the adverse effects caused by multiple users interacting with light and shadow at the same time and the interference of ambient light. The intelligent light and shadow interactive lighting control based on dynamic perception has low accuracy and needs improvement. Summary of the Invention

[0044] The present application is further described in detail below with reference to the accompanying drawings.

[0045] The embodiment of the present application discloses an intelligent light and shadow interactive lighting control system based on dynamic perception.

[0046] Reference Figure 1 , an intelligent light and shadow interactive lighting control system based on dynamic perception, including:

[0047] The light and shadow interactive channel creation module is configured to establish a link between the user to be tested and the guide machine worn by the user to be tested to obtain a user light and shadow interactive channel.

[0048] The regional audio matching module is configured to verify the reliability of the projection surface, output the usable result of the projection surface after verification, perform a projection operation on the chime exhibit to obtain the chime exhibit projection, partition the chime exhibit projection to obtain the exhibit projection partition result, obtain an audio data set, the audio data set includes multiple audio files, and match each region with each audio file to obtain a regional audio matching result.

[0049] The user interaction judgment module is configured to open the user light and shadow interaction channel and prompt the user to be tested that they can perform light and shadow interaction when the user to be tested is within the virtual light and shadow interaction range, and judge whether the user to be tested performs light and shadow interaction. If so, the user light and shadow interaction result is output.

[0050] The projection touch interaction analysis module is configured to determine whether the audio playback condition is triggered when the user to be tested touches the projection of the chime exhibit to interact with light and shadow. If the audio playback condition is triggered, the audio file is selected and played in real time.

[0051] The device touch interaction analysis module is configured to determine whether the audio playback condition is triggered when the user to be tested interacts with light and shadow based on the guide machine. If the audio playback condition is triggered, the audio file is selected and played in real time.

[0052] The ambient light interference analysis module is configured to detect whether there is any light other than the projection light shining on the projection surface after the user light and shadow interaction channel is turned on. If so, it is marked as interfering ambient light. Based on the interfering ambient light, it is determined whether the projection of the chime exhibit needs to be adjusted. If adjustment is required, the projection of the chime exhibit is adjusted.

[0053] Reference Figure 1 The light and shadow interactive channel creation module is used to establish a link between the user to be tested and the guide machine worn by the user to be tested to obtain a user light and shadow interactive channel, wherein the guide machine includes a guide touch screen and a guide earphone.

[0054] Reference Figure 1 The regional audio matching module is configured to verify the reliability of the projection surface, output the available result of the projection surface after verification, perform a projection operation on the chime exhibit to obtain the chime exhibit projection, partition the chime exhibit projection to obtain the exhibit projection partition result, obtain an audio data set, the audio data set includes multiple audio files, match each region with each audio file to obtain the regional audio matching result.

[0055] The specific implementation of the regional audio matching module is as follows:

[0056] The standard size range of the projection surface is determined based on the number and arrangement of components on display in the chime exhibits.

[0057] Among them, when the projection surface size is too large, the user cannot touch the various nodes of the virtual projection in time, resulting in an unsmooth light and shadow interactive experience. When the projection surface is too small, it is easy to cause errors when touching, affecting the user's light and shadow interactive experience. The projection surface size is too large or too small, which will affect the user's interactive experience during light and shadow interaction. Therefore, in the embodiment of the present application, the standard size range of the projection surface is determined by the number and arrangement of components of the chime exhibits, providing data support for the subsequent verification of the reliability of the projection surface.

[0058] The reliability of the projection surface is verified based on the size and flatness of the projection surface. When the size of the projection surface is within the standard size range of the projection surface and the flatness of the projection surface is higher than the preset projection flatness threshold, the projection surface passes the verification and the projection surface usable result is output.

[0059] In the embodiment of the present application, the reliability of the projection surface is verified by the flatness and size of the projection surface, thereby reducing the risk of poor user light and shadow interaction experience caused by inappropriate projection surface size or uneven projection surface.

[0060] Based on the available result of the projection surface, a projection operation is performed on the chime exhibit to obtain a chime exhibit projection, and the chime exhibit projection is divided into regions according to the number and arrangement of musical instruments in the chime exhibit projection to obtain an exhibit projection partition result.

[0061] Among them, the chime bells exhibit refers to the Zenghouyi chime bells, the prototype of which has 64 bells and 32 chimes. The areas are divided according to the number of devices projected by the chime bells exhibit and the arrangement of the devices. Each area in the exhibit projection zoning results includes one bell or one chime.

[0062] An audio dataset is obtained, which includes audio files recording the sounds of various instruments in the chime exhibits.

[0063] Based on the exhibit projection partition results and the audio dataset, each area is matched with each audio file one by one to obtain the regional audio matching results.

[0064] Reference Figure 1 The user interaction judgment module is configured to open the user light and shadow interaction channel and prompt the user to be tested that the light and shadow interaction can be carried out when the user to be tested is in the virtual light and shadow interaction range, and judge whether the user to be tested is performing light and shadow interaction. If the user interacts, the user light and shadow interaction result is output.

[0065] The specific execution method of the user interaction judgment module is as follows:

[0066] The scope of virtual light and shadow interaction is determined based on the projection location of the chime exhibits and the layout of exhibits in the exhibition area.

[0067] In actual use, when a user approaches an exhibit, an introduction to the exhibit begins playing in the guide earphones. In this embodiment of the application, the virtual light and shadow interaction range is determined by the location of the chime exhibit projection and the layout of the exhibits in the exhibition area. The user can understand and interact with the chime exhibit within the virtual light and shadow interaction range. By accurately determining the virtual light and shadow interaction range, the user's experience of light and shadow interaction with the chime exhibit in the exhibition area is enhanced.

[0068] Specifically, based on the projection location of the chime exhibit, it is determined whether there are other exhibits in front, on the left, and on the right of the chime exhibit. If so, the front exhibit is marked as the front adjacent exhibit, and the left and right exhibits are marked as the side adjacent exhibits.

[0069] A first feature point is determined based on the front adjacent exhibit. If the front adjacent exhibit and the projection of the chime exhibit are oriented in the same direction, the first feature point is the midpoint of the boundary of the area of the front adjacent exhibit close to the projection of the chime exhibit. If the front adjacent exhibit and the projection of the chime exhibit are oriented in different directions, a first area ratio is obtained by determining the ratio of the area of the projection of the chime exhibit to the area of the area of the front adjacent exhibit. A front connecting line segment is obtained by connecting the midpoint of the lower boundary of the projection of the chime exhibit and the midpoint of the boundary of the front adjacent exhibit. The first feature point is determined based on the first area ratio and the front connecting line segment. The first area ratio is the ratio of the distance from the first feature point to the midpoint of the lower boundary of the projection of the chime exhibit to the distance from the first feature point to the midpoint of the boundary of the front adjacent exhibit.

[0070] If the lateral adjacent exhibit area seamlessly adjoins the projection surface of the chime exhibit, the connection point between the chime exhibit projection and the lateral adjacent exhibit area is marked as the second feature point. If a passage exists between the lateral adjacent exhibit area and the projection surface of the chime exhibit, the ratio of the chime exhibit projection area to the area of the lateral adjacent exhibit area is used to obtain the second area ratio. The minimum value between the lower boundary vertex of the chime exhibit projection and the boundary point of the lateral adjacent exhibit is selected to obtain the lateral connecting line segment. Based on the second area ratio and the lateral connecting line segment, the third feature point is determined. The ratio of the distance from the third feature point to the edge connection point of the chime exhibit projection to the distance from the third feature point to the boundary point of the lateral adjacent exhibit is the second area ratio.

[0071] A characteristic arc is created according to the first characteristic point, the second characteristic point and / or the third characteristic point, and a range in which the characteristic arc is projected toward the chime exhibit is marked as a virtual light and shadow interaction range.

[0072] The user to be tested is located to obtain the user's real-time position, and it is determined whether the user's real-time position is within the virtual light and shadow interaction range. If it is within the virtual light and shadow interaction range, the user's light and shadow interaction channel is opened, and an introduction to the chime exhibits is played based on the guide headphones. After the introduction of the chime exhibits is played, the user to be tested is prompted to perform virtual light and shadow interaction operations.

[0073] Determine whether the user's hand touch is on the virtual projection or on the guide machine. If it is on the guide machine and the guide touch screen displays the chime exhibit, output the device touch interaction result; if it is on the chime exhibit projection, output the projection touch interaction result.

[0074] The device touch interaction result and the projection touch interaction result are combined to form the user light and shadow interaction result.

[0075] Reference Figure 1 The projection touch interaction analysis module is configured to determine whether the audio playback condition is triggered when the user to be tested touches the projection of the chime exhibit to interact with light and shadow. If the audio playback condition is triggered, the audio file is selected and played in real time.

[0076] The specific implementation of the projection touch interaction analysis module is as follows:

[0077] After receiving the projection touch interaction result, the touch position of the hand of the user to be tested is detected in real time to obtain the user projection touch point position information.

[0078] The area to which the user projection touch point position information belongs in the exhibit projection partition result is determined to obtain the user projection interaction mark area.

[0079] Specifically, the radar system and the sensing system are used to track the user projection contact position information of the user to be tested, and the high-definition camera is used to determine whether the user projection contact position information is the position touched by the hand of the user to be tested. In the embodiment of the present application, the radar system and the sensing system are used to preliminarily track the user projection contact position information of the user to be tested, and the high-definition camera is used to further verify the contact position of the user to be tested, thereby improving the accuracy of the contact detection of the user to be tested, ensuring that the detected user projection contact position information is accurately matched with the user to be tested, and reducing the risk of inaccurate detection when multiple users interact with light and shadow at the same time.

[0080] Based on the regional audio matching results, the audio file corresponding to the user projection interaction marked area is selected and marked as the projection interaction playback audio file.

[0081] The specific implementation of the projection touch interaction analysis module also includes:

[0082] When the user to be tested continuously touches multiple areas in the exhibit projection partition result, the order in which the user to be tested touches each user projection interaction mark area is determined based on the user projection contact point position information to obtain the projection interaction mark area priority result.

[0083] Based on the projection interactive mark area priority result, the playback priority of each projection interactive playback audio file is judged to obtain the projection playback audio priority result, wherein the playback time of each projection interactive playback audio file is consistent with the touch time of the user to be tested in the corresponding user projection interactive mark area.

[0084] Using guide headphones, the projected interactive audio files are played in real time based on the projected audio priority results and the playback time of the projected interactive audio files.

[0085] Reference Figure 1 The device touch interaction analysis module is configured to determine whether the audio playback condition is triggered when the user to be tested performs light and shadow interaction based on the guide machine. If the audio playback condition is triggered, the audio file is selected and played in real time.

[0086] The specific implementation of the device touch interaction analysis module is as follows:

[0087] After receiving the device's touch interaction results, the chime exhibit is projected onto the navigation touchscreen based on the exhibit projection zoning results. While the chime exhibit is projected onto the navigation touchscreen, users can zoom in and out of each area using two fingers. This zooming in and out feature facilitates the accuracy of the light and shadow interaction of the chime exhibit by the user under test.

[0088] When the hand of the user to be tested touches the navigation touch screen in real time, the area corresponding to the exhibit projection partition result is obtained as the user device interaction mark area.

[0089] Based on the regional audio matching results, the audio file corresponding to the user device interaction marked area is selected and marked as the device interaction playback audio file.

[0090] The specific implementation of the device touch interaction analysis module also includes:

[0091] When the user to be tested continuously touches multiple areas in the projection partition result of the corresponding exhibit on the guide touch screen, the order in which the user to be tested touches each user device interaction mark area is determined to obtain the device interaction mark area priority result.

[0092] Based on the device interaction mark area priority result, the playback priority of each device interactive audio file is judged to obtain the device audio playback priority result, wherein the playback time of each device interactive audio file is consistent with the touch time of the user to be tested in the corresponding user device interaction mark area.

[0093] Using the navigation headphones, the device interactive playback audio files are played in real time based on the device playback audio priority results and the playback time of the device interactive playback audio files.

[0094] Reference Figure 1 The ambient light interference analysis module is configured to detect whether there is any light other than the projection light shining on the projection surface after the user light and shadow interaction channel is turned on. If so, it is marked as interfering ambient light. Based on the interfering ambient light, it is determined whether the projection of the chime exhibit needs to be adjusted. If adjustment is required, the projection of the chime exhibit is adjusted.

[0095] The specific execution method of the ambient light interference analysis module is as follows:

[0096] After the user light and shadow interactive channel is opened, a filter is set at the projection receiving end, and then real-time detection is performed to see whether there is any other ambient light irradiating the chime exhibit projection in addition to the projection light. If so, the ambient light directed towards the chime exhibit projection is marked as interfering ambient light.

[0097] The interfering ambient light is detected to obtain interfering ambient light information, where the interfering ambient light information includes the duration of the interfering ambient light exposure, the intensity of the interfering ambient light, and the wavelength band of the interfering ambient light.

[0098] When the duration of the interference ambient light exposure is greater than or equal to a preset interference light exposure duration threshold, the interference ambient light needs to be compensated and an interference light compensation result is output.

[0099] In actual application, for example, the threshold of the duration of interference light exposure is set to 1 second. If the duration of interference ambient light exposure is less than 1 second, it is determined that the interference ambient light has negligible influence on the light and shadow interaction of the projection of the chime exhibit, and there is no need to optically compensate for the interference environment. If the duration of interference ambient light exposure is greater than or equal to 1 second, it is determined that the interference ambient light affects the light and shadow interaction of the projection of the chime exhibit, and it is necessary to optically compensate for the interference environment and output the interference light compensation result.

[0100] After receiving the interference light compensation result, the projection light of each area in the exhibit projection partition result of the chime exhibit projection is adjusted based on the interference ambient light intensity and the interference ambient light band until the tone of the chime exhibit projection is unified.

[0101] Specifically, based on the wavelength band of the interfering ambient light, it is determined whether the interfering ambient light is broad-spectrum white light. If it is broad-spectrum white light, a white light interference determination result is output; if it is not broad-spectrum white light, a specific interference wavelength band determination result is output.

[0102] After receiving the white light interference determination result, the projection brightness of other areas except the area where the interfering ambient light is located is adjusted and increased, wherein the projection brightness increase value is the intensity of the interfering ambient light in the area where the interfering ambient light is located. After the adjustment, the brightness of each area of the projection of the chime exhibit is unified, and the optical compensation adjustment operation for the interfering ambient light is completed.

[0103] After receiving the specific interference band determination result, the compensation light band is determined based on the interference ambient light band.

[0104] For example, if the interfering ambient light band is a strong green light band, then compensating light in the red and blue light bands can adjust the overall color balance, and the compensating light bands are the red and blue light bands.

[0105] Based on the intensity of the interfering ambient light, the compensation light intensity of the compensation light band is determined; based on the compensation light band and the compensation light intensity, the overall color balance of the interfering ambient light is adjusted; and based on the interfering ambient light band, the interfering ambient light intensity, the compensation light band and the compensation light intensity, the compensation light of other areas in the projection of the chime exhibit except the area where the interfering ambient light is located is adjusted; after the adjustment, the brightness of each area of the projection of the chime exhibit is unified, and the optical compensation adjustment operation for the interfering ambient light is completed.

[0106] In a specific application, by setting a filter at the projection receiving end to initially block the interfering light, and then detecting in real time whether there is other ambient light irradiating the projection surface in addition to the projection light on the chime exhibit, if there is, the ambient light irradiating the chime exhibit projection is marked as interfering ambient light, and the parameters of the interfering ambient light are detected to obtain the interfering ambient light exposure time, the interfering ambient light intensity, and the interfering ambient light band. According to the interfering ambient light exposure time, it is determined whether it is necessary to optically compensate for the interfering ambient light. If necessary, the adjustment method for optically compensating the chime exhibit projection is determined based on the interfering ambient light band, and the degree of adjustment for optically compensating the chime exhibit projection is determined based on the interfering ambient light intensity. Then, the projection light of each area in the exhibit projection partition result in the chime exhibit projection is adjusted, thereby improving the pleasure of the user to be tested when experiencing the light and shadow interactive experience based on dynamic perception. The above are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
