[0002] Projection for exhibition hall layout is one of the important means to enhance the exhibition experience. It uses advanced projection technology to present digital content to audiences in an intuitive and vivid way, enhancing the interactivity and immersion of the exhibition.

[0003] When projection for exhibition hall layout is first put into use, a suitable projection display method needs to be selected. The traditional projection display method generally first selects a suitable projection technology, then selects a projection wall of appropriate size in the exhibition hall, and then focuses on the projection distance of the projector and adjusts the picture brightness according to the indoor light intensity to ensure clear imaging.

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0024] Please refer to Figure 1 As shown, in one embodiment, the present application provides a projection display method for the layout of an intelligent exhibition hall, and the method includes: S1: First, turn on and preheat the projector, and collect the projection video file parameters of different exhibition halls and the environmental data of different exhibition halls through the data acquisition module; S2: Analyze the brightness requirement index of the video files in different exhibition halls through the terminal control module in combination with the projection video file parameters of different exhibition halls; S3: Analyze the overall brightness requirement of the projector by combining the brightness requirement index of the video files in different exhibition halls with the environmental data of different exhibition halls; S4: Adjust the projection brightness of the current exhibition hall by combining the analysis results of the overall brightness requirement of the projector; Through the above technical solutions, this embodiment provides a projection display method for the layout of an intelligent exhibition hall. First, turn on and preheat the projector, and collect the projection video file parameters of different exhibition halls and the environmental data of different exhibition halls through the data acquisition module. Then, analyze the brightness requirement index of the video files in different exhibition halls through the terminal control module in combination with the projection video file parameters of different exhibition halls, and analyze the overall brightness requirement of the projector by combining the brightness requirement index of the video files in different exhibition halls with the environmental data of different exhibition halls. Finally, the projection brightness of the current exhibition hall can be adjusted by combining the analysis results of the overall brightness requirement of the projector; Through this projection display method, this method first analyzes the brightness requirement index of the video files in different exhibition halls by combining the projection video file parameters of different exhibition halls. This data can reflect the complexity of the projection videos in different exhibition halls, such as whether they contain images with a large amount of details and rich color levels. Then, by combining this data with the environmental data of different exhibition halls, the overall brightness requirement of the projector can be analyzed, and the projection brightness of the current exhibition hall can be adjusted according to the analysis results. After combining diversified data such as the complexity of the projection video and environmental data, the rationality of brightness adjustment can be improved, and the color restoration, saturation, and quality of the projection screen can be improved.

[0025] The data collected in S1 includes: The parameters of the projection video files for different exhibition halls, including the resolution, memory size, contrast ratio, and frame rate of the projection video files for different exhibition halls; The environmental data of different exhibition halls, including the light intensity, projection distance, and power supply voltage inside different exhibition halls; Through the above technical solution, this example provides the data collected by the data acquisition module, including the parameters of the projection video files for different exhibition halls and the environmental data of different exhibition halls. Among them, the parameters of the projection video files for different exhibition halls include the resolution, memory size, contrast ratio, and frame rate of the projection video files for different exhibition halls. Since the exhibits in different exhibition halls are different, the corresponding projection videos are also different. By analyzing the data such as the resolution, memory size, contrast ratio, and frame rate of the projection video files for different exhibition halls, the complexity of the projection videos in different exhibition halls can be analyzed. Projection videos with high complexity generally contain images with a large number of details and rich color levels, and require higher contrast and brightness to be clearly presented. While projection videos with low complexity generally have fewer details and less rich color levels, and do not require too high brightness to be clearly presented. Therefore, by combining the parameters of the projection video files for different exhibition halls, reliable and diversified data support can be provided for subsequent adjustment of the projection video brightness to ensure the reliability of the adjustment results; The environmental data of different exhibition halls includes the light intensity, projection distance, and power supply voltage inside different exhibition halls. Among them, the light intensity and projection distance inside different exhibition halls directly affect the brightness setting, and the projection brightness needs to be dynamically adjusted according to the light intensity and projection distance. The power supply voltage is used to judge the state of the projector. When the power supply voltage is small, it will affect the state of the projector, resulting in a decrease in the brightness of the projection image. Therefore, by combining two types of data, namely the environmental data of different exhibition halls and the parameters of the projection video files for different exhibition halls, high-quality fusion data can be obtained, thereby providing reliable and diversified data support for subsequent adjustment of the projection video brightness and further ensuring the reliability of the adjustment results.

[0026] Please refer to Figure 2 As shown, the process of analyzing the brightness requirement index of the video files in different exhibition halls in S2 includes: S21: Calculate the brightness requirement index of the video files in different exhibition halls by combining the parameters of the projection video files for different exhibition halls collected by the data acquisition module; S22: Compare the brightness requirement index of the video files in different exhibition halls with a preset requirement index threshold; S23: Analyze the complexity of the video files in different exhibition halls by combining the comparison results in S22; S24: Decide how to adjust the projection brightness by combining the analysis results of the complexity of the video files in the same exhibition hall; Through the above technical solution, this example provides the analysis process in S2. First, by combining the projection video file parameters of different exhibition halls collected by the data acquisition module, the brightness demand index of the video files in different exhibition halls is calculated. Then, by comparing the brightness demand index of the video files in different exhibition halls with the preset demand index threshold, and by combining the comparison results in S22, the complexity of the video files in different exhibition halls is analyzed. Finally, based on the analysis results of the complexity of the video files in the same exhibition hall, a decision can be made on how to adjust the projection brightness; By setting it this way, the projection video file parameters of different exhibition halls can reflect the complexity of the projection video. Therefore, by combining this data to calculate the brightness demand index of the video files in different exhibition halls, the complexity of the video files in different exhibition halls can be analyzed. Then, based on this analysis result, accurate and reliable data support can be provided for subsequent decision-making on how to adjust the projection brightness, thus ensuring the reliability of the brightness adjustment result.

[0027] The analysis process in S2 includes: Through the formula The brightness demand index of the video file in the a-th exhibition hall is calculated ; where a is any exhibition hall, is the resolution size of the video played in the a-th exhibition hall, is the preset resolution size, is The standard value of, and the above standard value can be selected and set according to the allowable error in the empirical data, is a defined function. If , then let , otherwise, let , The memory size of the video played in the a-th exhibition hall, is the preset memory size, is the contrast size of the video played in the a-th exhibition hall, is the preset contrast size, is the encoding format influence coefficient, which is set by empirical fitting, is the frame rate size of the video played in the a-th exhibition hall, is the preset frame rate size; Through the above technical solution, this example provides the brightness demand index of the video file in the a-th exhibition hall, which can be obtained through the formula It is calculated that obviously, when the resolution of the video played in the a-th exhibition hall is higher than the preset resolution, and the memory, contrast, and frame rate of the video played in the a-th exhibition hall are larger, then the brightness requirement index of the video file in the a-th exhibition hall is lower, indicating that the projected video in the a-th exhibition hall is a video file with high complexity, containing a large number of details and rich color levels in the video, and requires higher brightness to avoid detail loss and color distortion. On the contrary, when the resolution of the video played in the a-th exhibition hall is less than the preset resolution, and the memory, contrast, and frame rate of the video played in the a-th exhibition hall are smaller, then the brightness requirement index of the video file in the a-th exhibition hall is smaller, indicating that the projected video in the a-th exhibition hall is a video file with low complexity, containing fewer details and lower richness of color levels in the video, and does not require higher brightness to avoid detail loss and color distortion; Through this calculation method, accurate and diversified data support can be provided for subsequent adjustment of the projector brightness to ensure the reliability of the adjustment result.

[0028] The analysis process in S2 further includes: By comparing the brightness requirement index of the video file in the a-th exhibition hall with the preset requirement index threshold for comparison; If , it is determined that the complexity of the projected video in the a-th exhibition hall is high, which means that there are many images with rich details and color levels in the video in this exhibition hall; If , it is determined that the complexity of the projected video in the a-th exhibition hall is low, which means that there are few images with rich details and color levels in the video in this exhibition hall; Through the above technical solution, in this embodiment, by comparing the brightness requirement index of the video file in the a-th exhibition hall with the preset requirement index threshold for comparison, through this comparison method, the complexity of the projected video in the a-th exhibition hall can be judged. The complexity of the projected video can reflect whether the video contains a large number of images with rich details and color levels, so as to further judge how to adjust the brightness to ensure the quality of the projected image, thereby avoiding problems such as insufficient contrast or detail loss caused by failure to consider the complexity and color requirements of the projected content, resulting in poor color restoration and saturation.

[0029] Furthermore, the analysis process in S2 further includes: When it is determined that the complexity of the projected video in the a-th exhibition hall is high, it is necessary to increase the brightness of the projected image to improve the quality and color restoration of the projected image; When it is determined that the complexity of the projection video in the a-th exhibition hall is low, it is not necessary to additionally increase the brightness of the projection image to ensure the quality and color restoration of the projection screen; Through the above technical solution, in this example, by combining the brightness demand index of the video file in the a-th exhibition hall with the preset demand index threshold according to the comparison result, it is possible to decide whether to increase the brightness of the projection image to improve the quality and color restoration of the projection screen for the high or low complexity of the projection video in the a-th exhibition hall, thereby providing data support for subsequent adjustment of the brightness of the projection image and improving the reliability of the brightness adjustment result.

[0030] Please refer to Figure 3 As shown, the process of analyzing the overall brightness demand of the projector in S3 includes: S31: Calculate the overall brightness demand index of the projectors in different exhibition halls by combining the brightness demand index of the video files in different exhibition halls with the environmental data of different exhibition halls; S32: Compare the overall brightness demand index of the projectors in different exhibition halls with the preset demand index threshold range; S33: Select a suitable projector brightness adjustment method by combining the comparison results of the overall brightness demand index of the projectors in different exhibition halls; Through the above technical solution, this example provides the analysis process in S3. First, calculate the overall brightness demand index of the projectors in different exhibition halls by combining the brightness demand index of the video files in different exhibition halls with the environmental data of different exhibition halls. Then, compare the overall brightness demand index of the projectors in different exhibition halls with the preset demand index threshold range. Finally, select a suitable projector brightness adjustment method by combining the comparison results of the overall brightness demand index of the projectors in different exhibition halls; By setting like this, in this example, by combining the environmental data of different exhibition halls with the brightness demand index of the video files in different exhibition halls, high-quality fusion data can be obtained. Since the fusion data is calculated based on diversified data, its accuracy and reliability are relatively high. Then, by comparing this data with the preset demand index threshold range, a suitable projector brightness adjustment method can be accurately selected, improving the accuracy and reliability of the subsequent brightness adjustment result.

[0031] The analysis process in S3 includes: Calculate the overall brightness demand index of the projector in the a-th exhibition hall through the formula ; ; Wherein, is the light intensity in the a-th exhibition hall, The light intensity adapted to the current brightness of the projector is the projection distance in the a-th exhibition hall is the projection distance adapted to the current brightness of the projector is the standard value of, and the above standard value can be selected and set according to the allowable error in the empirical data is the power supply voltage value of the a-th exhibition hall is the preset power supply voltage value is the standard value of, and the above standard value can be selected and set according to the allowable error in the empirical data; Through the above technical solution, this example provides the overall brightness requirement index of the projector in the a-th exhibition hall , which can be obtained by the formula Obviously, when the light intensity in the a-th exhibition hall is higher than the light intensity adapted to the current brightness of the projector, the projection distance in the a-th exhibition hall is greater than the projection distance adapted to the current brightness of the projector, and the power supply voltage value of the a-th exhibition hall is less than the preset power supply voltage value, then the overall brightness requirement index is larger, indicating that in the current use environment, the projector requires a higher brightness to improve the clarity of the projection image. On the contrary, when the light intensity in the a-th exhibition hall is lower than the light intensity adapted to the current brightness of the projector, the projection distance in the a-th exhibition hall is less than the projection distance adapted to the current brightness of the projector, and the power supply voltage value of the a-th exhibition hall is greater than the preset power supply voltage value, then the overall brightness requirement index is smaller, indicating that the clarity of the projection image in the current use environment of the projector is sufficient, and the brightness needs to be reduced to relieve the burden on the eyes and reduce costs; By setting like this, accurate data can be provided for subsequent judgment on how to adjust the brightness of the projector.

[0032] The analysis process in S3 further includes: By comparing the overall brightness requirement index of the projector in the a-th exhibition hall with the preset requirement index threshold range ; If , it is judged that when projecting in this exhibition hall, the projection brightness of the projector needs to be reduced; If , it is judged that when projecting in this exhibition hall, the projection brightness of the projector does not need to be adjusted; If , it is judged that when projecting in this exhibition hall, the projection brightness of the projector needs to be increased; Through the above technical solution, in this example, the overall brightness requirement index of the projector in the a-th exhibition hall will be compared with the preset requirement index threshold range . Since this data is the brightness requirement index of the video file in the a-th exhibition hall , it is corrected. Diversified data can improve the reliability of the calculation result. Therefore, through this comparison method, an accurate judgment can be made on the projection brightness adjustment method of the projector when projecting in this exhibition hall, so as to ensure that the projected image after brightness adjustment has good clarity and color saturation, and can reduce the burden on the eyes and cost.

[0033] The adjustment process in S4 includes: Calculate the adjusted brightness of the projector in the a-th exhibition hall through the formula ; Among them, is the preset brightness of the projector, is the adjustment coefficient look-up table function, is the adjustment coefficient look-up table function. Because the influence degree of the value range of in the empirical data on the brightness is obtained based on the test data, is the error influence coefficient, which is set according to empirical fitting; Through the above technical solution, this example provides the adjusted brightness of the projector in the a-th exhibition hall, which can be calculated through the formula . By combining the brightness requirement index of the video file in the a-th exhibition hall and the environmental data in the a-th exhibition hall, the overall brightness requirement index of the projector in the a-th exhibition hall is calculated. Based on diversified data, the accuracy of the calculation result can be guaranteed. Then, by combining the preset brightness data of the projector, the adjusted brightness of the projector under different adjustment methods can be calculated. The reliability and accuracy of this calculation result are relatively high, which can ensure that the adjusted brightness can not only improve the color restoration degree, saturation and the quality of the projected image, but also will not be too bright to cause visual fatigue to users.

[0034] The adjustment process in S4 also includes: Adjust the brightness parameter of the projector by combining the adjusted brightness of the projector in the a-th exhibition hall; Through the above technical solution, when the adjusted brightness After that, the current brightness parameter of the projector can be adjusted through the terminal control module, which is convenient and fast, and there is no need for manual brightness adjustment to avoid human errors.
