Description

Technical Field

[0002] Although a natural simulation environment is created for animals in wildlife parks, many artificial light sources (such as street lights, decorative lights, surveillance lights, etc.) are often installed to facilitate visitors' visits and the work of park staff. However, the sleep rhythm of animals is formed according to the laws of natural light. Therefore, the light radiation from artificial lights often interferes with the sleep rhythm of animals, causing their sleep rhythm to be disordered. Therefore, artificial light is a kind of light pollution for animals. Currently, staff can use relevant instruments to detect the radiation parameters (such as wavelength) of light sources in zoos, but it is difficult to accurately estimate the distribution of the radiation areas of these light sources, and thus it is impossible to accurately determine the extent of the impact of light radiation from artificial lights on the sleep rhythms of various animals. In other words, it is difficult to accurately assess the degree of light pollution in the living environment of animals, and thus it is impossible to make corresponding adjustment measures, which brings risks to the health of animals.

DETAILED DESCRIPTION

[0010] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0011] In order to illustrate the technical solution described in this application, specific embodiments are provided below.

[0012] Figure 1 A monitoring data-based environmental assessment method provided in Example 1 of the present application is shown, which is applied to a terminal device. The monitoring data-based environmental assessment method includes: S1: After receiving the evaluation instruction sent by the user terminal of the staff, instruct the staff to perform wavelength detection on the light of each light source in the zoo; S2: Perform light radiation simulation on each light source to determine the radiation area of ​​the light source in the zoo; S3: Retrieve the operating time period of each light source, and determine the distribution of light of each wavelength in the zoo according to the operating time period of each light source and the corresponding radiation area; S4: Obtain surveillance videos of the zoo, determine the activity areas of various animals in the zoo based on the surveillance videos, and thus determine a heat map of the activity areas of each animal; S5: Obtaining sleep rhythm information of each animal, and determining the degree to which the sleep rhythm of the animal is affected based on the sleep rhythm information, the activity area heat map, and the distribution of light of each wavelength; S6: Evaluate the light pollution level in the zoo based on the various impact levels, and send the obtained light pollution level to the user terminal of the staff to prompt the staff to adjust the light source based on the light pollution level.

[0013] In this embodiment, if Figure 2As shown, the method is executed in a terminal device, which can be an independent physical server or terminal, or a server cluster composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud servers, cloud databases, cloud storage and CDN; the terminal device communicates with the user end of the zoo staff, and the user end can be a mobile phone, tablet computer, laptop computer, etc.; a number of cameras are provided in the zoo, each camera is connected to the terminal device, and the surveillance video collected by the camera can be sent to the terminal device.

[0014] In this embodiment, when a staff member needs to conduct a light pollution assessment, he or she sends an assessment instruction to the terminal device through his or her user terminal. After receiving the instruction, the terminal device can execute the method. The light signal received by the animal's retina is transmitted to the suprachiasmatic nucleus in the brain through the retinal-suprachiasmatic nucleus pathway. The suprachiasmatic nucleus is the core regulatory center of the biological clock, which adjusts and calibrates the animal's circadian rhythm based on the received light signal. Different animals have different sensitivities to different wavelengths of light due to their different retinal structures (for example, the sensitive wavelength of horses is 480-490nm). Therefore, different animals need to be exposed to light in the specific wavelength range corresponding to their retinal structure before their rhythm is affected. In a zoo, various animals have their own activity areas. If light that may affect the sleep rhythm of an animal is radiated into the animal's activity area, there is a risk that the light will radiate into the animal's retina, thereby affecting the animal's rhythm. Therefore, if the light radiates into the animal's activity area, it can be regarded as causing light pollution to the animal's activity area.

[0015] In this embodiment, each light source is preset with a light-on time and a light-off time. The period between the light-on time and the light-off time is the operating time period of the light source, which is stored in the terminal device; the activity area of ​​an animal is the area where the animal may potentially appear, and the activity area heat map can represent the possibility of the animal appearing at each location in the activity area. The higher the possibility, the higher the degree of light pollution of the light radiated at that location; the sleep rhythm information of an animal includes the sleep period of the animal under natural conditions (i.e., without interference from artificial light sources) and the affected wavelength range corresponding to the light that affects the sleep rhythm of the animal (i.e., the wavelength range that will affect the sleep rhythm of the corresponding animal), wherein the sleep period is the common sleep period of the animal (without considering specific individuals), and the data can be directly retrieved from existing animal rhythm observation and research data; the terminal device is preset with an affected wavelength range database (the data in the database is existing research data), which includes the affected wavelength ranges of various animals and can be retrieved and used by the terminal device.

[0016] In this embodiment, a critical light pollution level is preset in the user terminal. When the user terminal receives the light pollution level sent by the terminal device, if it exceeds the critical light pollution level, it indicates that the current light pollution in the zoo is relatively serious, which has a great impact on the sleep rhythm of animals and needs to be adjusted. The user terminal will send a prompt signal to prompt the staff to adjust the light source.

[0017] In the present application, the distribution of lights of various wavelengths in the zoo can be determined through the wavelength detection data of each light source and the position of each light source in the zoo by the staff, and the heat map of the activity area of ​​the animals can be determined through monitoring video. By comparing the distribution of lights of various wavelengths and the intersection of the activity areas, combined with the sleep period of the animals and the affected wavelength range, the impact on the sleep rhythm of the animals can be accurately estimated, that is, the light pollution situation of the living environment of the animals can be accurately evaluated through quantitative data.

[0018] As a preferred embodiment, instructing staff to perform wavelength detection on the lights of each light source in the zoo includes: Generate a floor plan of the zoo, identify the location of each light source in the floor plan, and determine the model of each light source; For each model, identify the positions of all light sources corresponding to the model on the plan view and select one of the positions as the detection position; Send the detection location to the user terminal of the detection personnel to instruct the detection personnel to go to the detection location to perform wavelength detection on the light of the corresponding light source; After receiving the wavelength detected by the user end, mark the wavelength at the detection position and mark the wavelength at the positions of all other light sources of the same model on the floor plan.

[0019] In this embodiment, the floor plan is drawn in advance by the staff and stored in the terminal device, which includes the locations of all light sources in the zoo area; for light sources of the same model, only one of them can be selected for detection; the staff can use instruments such as spectrometers and laser wavelength meters to detect the wavelength of the light source, and input the wavelength into the user end and send it to the terminal device.

[0020] As a preferred embodiment, light radiation simulation is performed on each light source to determine that the radiation area of ​​the light source in the zoo includes: Generate a stereogram of the area where the light source is located; Retrieve the light source model of the light source according to the corresponding model; Determine the spatial position of the light source, and place the light source model in the stereogram according to the spatial position; Generate simulated light at the light source model according to the light radiation mode corresponding to the light source model, and identify the ground area radiated by the simulated light in the stereogram; A partial area corresponding to the ground area is identified in the plan view, ie, the radiation area.

[0021] In this embodiment, the stereogram of the area where the light source is located is a circular area with a radius (such as 50 meters or 100 meters) set with the light source as the center, so that the light of the light source can fall within the area; the terminal device is provided with AI 3D modeling software (such as Meshy The terminal can use surveillance images from the zoo's surveillance equipment to determine the regional view of the area where the light source is located, and then mobilize the 3D modeling software to perform 3D modeling based on the regional view. The terminal also has built-in light source models for various light sources. The planar position of the light source can be determined from the plan view, and the height of the light source can be determined from the surveillance video, thereby determining the spatial position of the light source. The light source model is then placed in the stereogram based on this spatial position to complete the modeling. The shape of each light source model and the covering method of the lampshade determine its optical path, which in turn leads to different radiation directions and light diffusion methods. The planning and design before the construction of the zoo includes lighting design, which includes each light source used and the corresponding optical path form. The lighting design information is stored in the terminal device, allowing the terminal to determine the optical path form of a certain light source at any time based on the lighting design information. The 3D modeling software has a built-in lighting simulation plug-in. After determining the optical path form of the light source, simulated lighting can be generated according to the optical path form on the stereogram using the light source as the starting point, and the ground area irradiated by the simulated light can be identified in the stereogram.

[0022] As a preferred embodiment, determining the distribution of lights of various wavelengths in the zoo according to the operating time periods of each light source and the corresponding radiation areas includes: S31: In the plane diagram, light sources with the same corresponding wavelength are grouped into the same light source set; S32: The earliest start time of each operating time period is defined as a first time period, the latest end time of each operating time period is defined as a second time period, and the time period from the first time period to the second time period is determined as the total operating time period; S33: The first moment in the total running time period is taken as the base moment; S34: Select a light source set, compare the operating time period of each light source in the light source set with the base time to determine whether the base time is within the operating time period; if so, determine the light source as the first light source; S35: Simultaneously determining the radiation areas of all first light sources on the plan view as the distribution areas of the light of the corresponding wavelength of the light source set at the base time, and repeating steps S34 to S35 until the distribution areas of the light of the corresponding wavelength of each light source set at the base time are obtained; S36: Taking the next moment in the total operating period as the base moment, execute steps S34 to S36 until the distribution area of ​​the light of the corresponding wavelength of each light source set at each moment in the total operating period is obtained.

[0023] In this embodiment, since all light sources operate within the determined total operating time period, artificial lights are distributed in the zoo only during the time periods within the total operating time period. Determining the distribution of lights of various wavelengths in the zoo means determining the distribution area of ​​lights of various wavelengths at each moment in the total operating time period.

[0024] As a preferred embodiment, the acquired surveillance video includes surveillance videos of several total operating time periods in the past; and the activity areas of various animals in the zoo determined based on the surveillance video include: S41: Divide the plan into several sub-areas; S42: Select an animal as the target animal; S43: For each sub-region, identifying a target region corresponding to the sub-region in the surveillance video; S44: Identify whether a target animal stays in a target area in the surveillance video; S45: If yes, mark the sub-region corresponding to the target region on the plane map; S46: determining the area consisting of all marked sub-areas as the activity area of ​​the target animal and storing the area; S47: Restore the plane map, select another animal as the target animal, and execute steps S43 to S47 until the activity area of ​​each animal in the zoo is obtained.

[0025] In this embodiment, the surveillance video obtained is the surveillance video of all cameras installed in the zoo, covering all animal activity areas in the zoo; the monitoring period of the surveillance video can be a set period of time in the past (such as the past week, 15 days or other days), and then only the total operating period of each day in the video is retained, and the non-total operating period is eliminated; in this embodiment, each sub-area can be a square area of ​​the same area, and the area of ​​the sub-area corresponding to the actual area of ​​the ground can be 5 square meters or other area, whichever is larger, based on the ability to accommodate the animals in the zoo.

[0026] like Figure 3 As shown, as a preferred embodiment, determining the activity area heat map of each animal includes: For each animal, identify the area where the animal lives on the floor plan; Determine the appearance time density of the animal in each sub-area of ​​the corresponding activity area, and render the sub-area according to the size of the appearance time density. The rendered sub-areas form the activity area heat map. The greater the appearance time density, the darker the rendering color of the sub-area. The appearance duration density of any animal in any sub-area of ​​the corresponding activity area is calculated using the following formula: in, is the appearance duration density, is the total duration of the surveillance video, The total time that the animal appears in the sub-area; After obtaining the activity area heat map, the weighted area of ​​the activity area is calculated using the following formula: in, is the weighted area of ​​the active region, is the area of ​​the i-th sub-region in the active region, is the appearance duration density of the i-th sub-region (i.e., the area weight of the corresponding sub-region), and n is the number of sub-regions in the active area.

[0027] The sleep rhythm information of an animal includes the sleep period of the animal under natural conditions and the wavelength range of light that affects the sleep rhythm of the animal. The degree of influence on the sleep rhythm of the animal is determined based on the sleep rhythm information, the heat map of the activity area, and the distribution of light of each wavelength, including: S51: determining a wavelength that falls within the impact wavelength range corresponding to the animal as a target wavelength; S52: taking the first moment of the sleep period of the animal as the comparison moment; S53: determining the total distribution area of ​​the light corresponding to each target wavelength at the comparison moment on the plane map; S54: Identify the activity area of ​​the animal on the plan map to determine the local area within the activity area that overlaps with the total distribution area; S55: Calculating the weighted area of ​​the local area based on the activity area heat map; S56: Dividing the weighted area of ​​the local area by the weighted area of ​​the active area to obtain the area ratio corresponding to the comparison time; S57: taking the next moment of the sleep period of the animal as the comparison moment, executing steps S53 to S57 until the area ratio corresponding to each moment of the sleep period is obtained; S58: Calculate the degree to which the sleep rhythm of the animal is affected using the following formula: in, is the degree to which the sleep rhythm of the animal is affected. is the area ratio corresponding to the jth moment in the sleep period, m is the number of moments in the sleep period, is the impact adjustment coefficient.

[0028] The degree of light pollution is calculated using the following formula: in, is the degree of light pollution, is the degree of influence on the sleep rhythm of the kth animal, and P is the type of animals in the zoo.

[0029] In this embodiment, the rendering color of the activity area heat map can be red or other colors; a color depth corresponding to each appearance duration density is pre-set. After the appearance duration density of a sub-area is obtained, the depth of its rendering color can be determined, and the sub-area is rendered with the rendering color of the depth; In this embodiment, the appearance time density of any animal in any sub-area of ​​the corresponding activity area is, that is, the ratio of the total appearance time of the animal in the sub-area to the total duration of the surveillance video (that is, the sum of the durations of all total operation periods); the total distribution area is the sum of the distribution areas corresponding to all target wavelengths; since the activity area is composed of regular sub-areas, and the shape of the total distribution area is irregular, some sub-areas in the activity area only partially overlap with the total distribution area. In this embodiment, such sub-areas are also regarded as part of the local area; the weighted area of ​​the activity area is the sum of the weighted areas of each sub-area, and the weighted area of ​​each sub-area is the area of ​​the sub-area multiplied by the weight, and the weight is the corresponding appearance time density; the weighted area of ​​the local area is calculated in the same manner as the weighted area of ​​the activity area, that is, the area of ​​each sub-area in the local area is multiplied by the corresponding appearance time density; In this embodiment, It can be set to 10; the time interval between two adjacent moments in this embodiment can be 1 minute, or other time intervals. The smaller the setting, the higher the calculation accuracy. In this embodiment, the obtained light pollution level is the result of the comprehensive impact on the rhythms of all animals, and has comprehensive representation. The impact of each animal is obtained by calculating the radiation conditions of the activity area of ​​the animal at each moment during the sleep period. The calculation process is very detailed and accurate, and it can accurately characterize whether the light source setting in the zoo is reasonable or not.

[0030] In addition, when the light source needs to be adjusted, the terminal device can display the current floor plan (including the light source layout and the operating time of each light source), and the staff can directly simulate the adjustment of the light source on the terminal device. The simulation adjustment method includes but is not limited to moving the position of the light source, changing the model of the light source, and adjusting the operating time of the light source. After each adjustment is completed, the terminal device can recalculate the light pollution level through this method, and then compare it with the critical light pollution level. If the newly calculated light pollution level is not lower than the critical light pollution level, the user is prompted to continue to make adjustments. This cycle is repeated until the newly calculated light pollution level is lower than the critical light pollution level and the adjustment is completed. The staff can then make actual adjustments to the light sources in the zoo based on the relevant parameters of each light source on the final adjusted floor plan.

When the computer program is executed by the processor, the processor performs the steps of the environmental assessment method based on monitoring data, specifically including: S1: After receiving the evaluation instruction sent by the user terminal of the staff, instruct the staff to perform wavelength detection on the light of each light source in the zoo; S2: Perform light radiation simulation on each light source to determine the radiation area of ​​the light source in the zoo; S3: Retrieve the operating time period of each light source, and determine the distribution of light of each wavelength in the zoo according to the operating time period of each light source and the corresponding radiation area; S4: Obtain surveillance videos of the zoo, determine the activity areas of various animals in the zoo based on the surveillance videos, and thus determine a heat map of the activity areas of each animal; S5: Obtaining sleep rhythm information of each animal, and determining the degree to which the sleep rhythm of the animal is affected based on the sleep rhythm information, the activity area heat map, and the distribution of light of each wavelength; S6: Evaluate the light pollution level in the zoo based on the various impact levels, and send the obtained light pollution level to the user terminal of the staff to prompt the staff to adjust the light source based on the light pollution level.
