[0030] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. For example, the flowcharts and block diagrams in the accompanying drawings show the possible architectures, functions and operations of the systems, methods and computer program products according to multiple embodiments of the present invention. In this regard, each box in the flowchart or block diagram may represent a module, a program segment or a part of a code, and the module, a program segment or a part of a code contains one or more executable instructions for implementing the specified logical functions. It should also be noted that in some alternative implementations, the functions marked in the box may also occur in an order different from that marked in the accompanying drawings. For example, two consecutive boxes can actually be executed substantially in parallel, and they may sometimes be executed in the opposite order, depending on the functions involved. It should also be noted that each box in the block diagram and / or the flowchart, and the combination of boxes in the block diagram and / or the flowchart, can be implemented by a dedicated hardware-based system that performs a specified function or action, or can be implemented by a combination of dedicated hardware and computer instructions. In addition, the functional modules in the various embodiments of the present invention can be integrated together to form an independent part, or each module can exist separately, or two or more modules can be integrated to form an independent part.

[0031] With the increase in deep sky astrophotography enthusiasts, accurate celestial positioning and shooting plans have become the key to obtaining high-quality images. Traditional astrophotography methods require photographers to have high professional knowledge, and equipment debugging is cumbersome and time-consuming. For example, steps such as manually adjusting the equatorial mount and calculating the position of celestial bodies are not only challenging for beginners, but also easily affect shooting efficiency. With the increasing demand for automation, more and more users hope to simplify these operations and achieve a more efficient shooting process.

[0032] At present, deep sky photography software such as MaximDL, Sequence Generator Pro and The SkyX lack the function of automatically analyzing the position of celestial bodies and generating shooting plans. Although some software provides some automatic functions, users still need to install additional plug-ins to achieve image analysis, and the operation is complicated and lacks simple image collection and selection functions; users still face many tedious manual operations and configurations during the shooting process.

[0033] As the demand for automation and simplified operations increases, astronomical photography software is expected to develop in a more intelligent direction; improving user experience and lowering the operational threshold, thereby promoting deep sky astrophotography to a more convenient and efficient direction, especially among beginners and non-professional users.

[0034] Based on this, the present application proposes a method, system, electronic device and computer program product for astronomical photography planning. The astronomical photography planning can comprehensively consider various factors that affect astronomical photography, and can automatically provide a shooting plan from selecting a target celestial body to providing a target celestial body, which greatly simplifies the shooting process, not only lowers the threshold for astronomical photography, but also significantly improves the user experience.

[0035] Please see Figure 1 , Figure 1 The first flow chart of the astronomical photography planning method provided in the embodiment of the present application; the present application provides an astronomical photography plan, and the astronomical photography method can be Figure 7 electronic devices to perform.

[0036] Step S100: Identify at least one target celestial object in the target image and determine the altitude angle information of the target celestial object.

[0037] In the above step S100, the target celestial body in the target image is identified, and the altitude angle information of the target celestial body is determined. The target image can be an image in a database or an image randomly taken by a user.

[0038] The altitude angle of a celestial body refers to the angle between the direction line from the observer's horizon to the celestial body and the horizontal line (horizon). This angle can be used to indicate the height of the celestial body relative to the horizon. Specifically, a larger altitude angle (the higher the celestial body is from the horizon) usually indicates better observation conditions, because the light path of the celestial body is shorter, the atmospheric interference is smaller, and the observation effect is clearer. Conversely, when the altitude angle is low (the celestial body is close to the horizon), the observation conditions of the celestial body are poor, because the light needs to pass through a thicker atmosphere and may be affected by atmospheric refraction, scattering, etc., resulting in a decrease in image quality. Therefore, accurately identifying the altitude angle information of celestial bodies is crucial to formulating a suitable shooting plan.

[0039] In an embodiment of the present application, the altitude angle of the target celestial body can be obtained by acquiring the equatorial coordinate position of the target celestial body through a database after the target celestial body is obtained, and the equatorial coordinate position is matched with the geographical location to obtain the altitude angle information of the target celestial body at different time periods.

[0040] Step S200: Generate a shooting plan for the target celestial body according to the meteorological elements at the target location and the altitude angle information of the target celestial body.

[0041] In the above step S200, a shooting plan of the target celestial body is generated according to the meteorological elements of the target position and the altitude angle information of the target celestial body.

[0042] Exemplarily, the meteorological elements include at least two of cloud cover, precipitation probability, light pollution conditions, wind speed, transparency, air pressure and moon phase.

[0043] When shooting, meteorological factors such as cloud cover, atmospheric transparency, wind speed, humidity and other factors will affect the clarity of celestial body images. For example, when the atmospheric transparency is low, the shooting effect may be affected even if the altitude angle of the celestial body is high. Combined with meteorological data, the system can evaluate the pros and cons of shooting opportunities and adjust shooting settings (such as exposure time, shooting angle, etc.) according to specific meteorological conditions.

[0044] By combining the altitude angle information of the target celestial body with real-time meteorological elements, the best shooting plan can be generated for each target celestial body. The shooting plan that comprehensively considers the weather and the position of the celestial body provided by the embodiment of the present application can maximize the optimization of image quality and ensure that the shooting is performed under the best conditions. For example, if the altitude angle of a celestial body is high at a certain moment and the meteorological conditions are good (such as less cloud cover and high atmospheric transparency), it can be recommended to the user to shoot at this time to obtain the best image effect.

[0045] The meteorological elements and altitude information in the embodiments of the present application are associated with time and will change over time. For example, if the shooting time of a certain celestial body is 8:00-9:00, it is necessary to refer to whether the altitude angle of the celestial body within this time is suitable for shooting.

[0046] pass Figure 1 It can be seen that the astronomical photography planning method provided by this application greatly simplifies the astronomical photography process by automatically identifying the target celestial body, obtaining the altitude angle information of the target celestial body, and generating a shooting plan based on meteorological conditions. It not only improves the accuracy and efficiency of celestial body photography, but also effectively reduces the dependence on user professional knowledge, so that even non-professional astronomy enthusiasts can obtain high-quality celestial body images through simple operations.

[0047] Please see Figure 2 , Figure 2A flowchart of obtaining the altitude angle information of a target celestial body provided in an embodiment of the present application; in an optional embodiment, the above step S100 identifies at least one target celestial body in a target image and determines the altitude angle information of the target celestial body, which can be achieved by the following steps:

[0048] Step S110: Acquire a target image from an image database.

[0049] In the above step S110, the image database of the embodiment of the present application can store and manage the target celestial body image. The user can conveniently select the celestial body image stored in the database by interacting with the database.

[0050] Importantly, the images in the image database are sorted based on user interaction indicators. The celestial body images in the image database provided by the embodiment of the present application are sorted according to user interaction indicators (such as user selection frequency, image quality score, shooting time, etc.), so that the most commonly used or highest quality images are ranked first. Through this sorting method, the required image resources can be provided to users more quickly.

[0051] By analyzing user interactions, such as past choices, preferences (e.g., images collected by users in the astronomical photography community), or image access frequency (e.g., heat maps within the software), the image database can intelligently adjust the order in which images are displayed. Users can more easily obtain images of target celestial bodies of interest, avoiding the tedious operation of manually selecting and searching for target images each time.

[0052] Step S120: preprocessing the target image, analyzing the target celestial body in the preprocessed target image, and determining the altitude angle information of the target celestial body.

[0053] In the above step S120, the target image is preprocessed to improve the accuracy of subsequent celestial body recognition. The preprocessing of the target image in the embodiment of the present application includes operations such as denoising and contrast enhancement. The image preprocessing can effectively improve the quality of the image, making the details of the celestial body in the image clearer, which is helpful for the subsequent recognition process.

[0054] For the pre-processed target image, the celestial body recognition algorithm (such as edge detection, feature extraction and pattern recognition, etc.) is used to automatically analyze the image and identify the celestial body. Users can select the target celestial body of their interest from among many celestial bodies to shoot. Then, according to the coordinates of the target celestial body, the observation time and the position of the celestial body in the sky, the altitude angle information of the celestial body is obtained.

[0055] pass Figure 2It can be seen that the image database of this embodiment is sorted according to the user interaction index, which can help users select the most relevant or best-quality image resources, perform celestial body recognition on the celestial body images selected by the user, and analyze the altitude angle information of the target celestial body. The celestial body shooting plan provided in the embodiment of the present application can not only shoot the target celestial body specified by the user, but also provide the user with an optional list of shot images, which greatly improves the user experience.

[0056] Please refer to Figure 3 , Figure 3 A second flow chart of the celestial body photography planning method provided in an embodiment of the present application; in an optional embodiment, the above step S200 generates a photography plan for the target celestial body according to the meteorological elements of the target position and the altitude angle information of the target celestial body, which can be achieved by the following steps:

[0057] Step S211: adding first weights to the altitude angle information of meteorological elements and target celestial bodies respectively, and calculating the shootability score of each target celestial body in each target time period.

[0058] In the above step S211, the first weight is added to the altitude angle information of the meteorological element and the target celestial body respectively, and the shootability score of the target celestial body in each target time period is calculated.

[0059] For example, the altitude angle of the target celestial body usually has a great influence on the image quality. The higher the altitude angle, the greater the angle between the celestial body and the horizon, and the better the observation effect. Therefore, this factor may be given a higher first weight. Meteorological factors (such as atmospheric transparency, cloud cover, wind speed, etc.) also have an important influence on image clarity, especially when the cloud cover and transparency are poor. Even if the altitude angle of the celestial body is very high, the shooting effect will be greatly limited. Therefore, the first weight setting of meteorological factors should also take into account their impact on shooting quality.

[0060] The photoability score is a comprehensive evaluation result based on weather conditions and celestial body altitude information, reflecting the ideality of photographing the celestial body at a specific time. A higher photoability score usually means that the shooting conditions during this period are good and suitable for shooting, while a lower score indicates that the shooting conditions during this period are poor and you may need to choose another period or adjust your shooting plan.

[0061] For example, assume that the target celestial body is Mars, and its position is known based on the sky forecast for the day. Through astronomical calculations, it is determined that Mars is at a higher position during a specific period of time (such as 9 p.m.), and the angle (90 degrees) between the target star (Mars) and the line connecting the observer and the horizon is about 40 degrees, which means that its altitude angle is 40 degrees. A first weight is assigned to this factor based on the altitude angle of the celestial body. Assume that the first weight of the impact of the altitude angle on the shooting quality is 0.6, because when the altitude angle of the celestial body is higher, the atmospheric interference is smaller and the image is clearer.

[0062] Assume that at 9 pm that day, the weather is sunny, the atmospheric transparency is good, the cloud cover is light, and the wind speed is moderate. The scores of the meteorological elements may be as follows:

[0063] Atmospheric transparency (affects image clarity): score 9 / 10, first weight 0.3.

[0064] Cloud cover (affecting visibility): score 8 / 10, first weight 0.2.

[0065] Wind speed (affects image stability): score 10 / 10, first weight 0.1.

[0066] Assume that the sum of the weighted values ​​of these meteorological elements is 9 (out of 10), and the comprehensive first weight of the meteorological factors has been set to 0.4.

[0067] Further, assuming that the altitude angle score is 8, the first weight of the altitude angle is 0.6; the meteorological element score is 9, and the first weight of the meteorological element is 0.4; then, the photofacility score = (8×0.6)+(9×0.4)=4.8+3.6=8.4. This higher score means that the conditions for photographing Mars are very suitable during this period.

[0068] Step S212: Determine the target celestial body for each target period according to the photographability score, and generate a photographing plan corresponding to the target celestial body, wherein the photographing plan includes the target celestial body, the photographing window period, and the photographing parameters.

[0069] In the above step S212, according to the shootability score of each target celestial body, the celestial body with a higher score is selected as the target celestial body in each time period. Once the target shooting celestial body for each time period is determined, a complete shooting plan is further generated. The shooting plan not only includes the target celestial body to be photographed, but also lists the shooting window period and shooting parameters in detail. The shooting window period refers to the shooting time period under the best weather conditions, and the shooting parameters include exposure time, ISO setting, focal length, camera angle, etc., to ensure that the shooting effect reaches the expected quality.

[0070] Continuing with the above example, the shooting plan of the embodiment of the present application at least includes the following contents:

[0071] Photographing target: For example, the deep sky photographing target NGC2237.

[0072] Bright field parameters: exposure 300s; ISO800 or gain 100; use bin1 mode; take 20 photos.

[0073] Bias field shooting: 50 shots are taken with the shortest exposure time of 32 microseconds to correct the electronic noise in the image. This part can be done during the day, and shooting can be achieved in the absence of light by covering the light shield with an electronic or manual cover.

[0074] Dark field shooting: set the exposure time to 300 seconds and shoot 40 pictures to eliminate the thermal noise generated by the camera sensor itself. Similarly, dark field shooting is also suitable for daytime, and the sunshade cover can be used to achieve a completely dark environment.

[0075] Flat field shooting: Use a 20 millisecond exposure time and take 100 pictures to correct for uneven lighting in the image. Flat field shooting requires a special flat field plate to ensure that light is evenly irradiated on the sensor. This step can also be done during the day.

[0076] Optionally, in the embodiment of the present application, a personalized shooting score and plan are generated by real-time analysis of the user's shooting habits, device performance, environmental conditions, and community hotspots. The shootable score is dynamically adjusted based on the user's historical data and device characteristics to help the user make the best shooting decision in different environments. At the same time, it can also combine the shooting experience of other users in the community to provide accurate shooting suggestions to help each user capture the ideal image at the best time.

[0077] In the process of generating a shooting plan, environmental factors such as shooting angle, lens selection, composition suggestions, and lighting can be taken into account, and detailed shooting plans can be provided to users in combination with equipment performance. According to changes in the shooting environment, appropriate shooting time and environment settings are recommended, and basic post-processing suggestions are provided to improve shooting quality. Users can manually adjust and optimize plans, and continuously learn through real-time feedback and evaluation, gradually improving the accuracy and innovation of personalized shooting plans.

[0078] The dynamic adjustments and comprehensive solutions proposed in the above process can be realized through artificial intelligence. With the continuous use and training of AI, AI will gradually optimize its shooting plan and be able to more accurately predict user needs and equipment performance. Through continuous user feedback (users' active adjustments to shooting plans and user feedback on shooting results), continuous training of AI not only improves the shooting success rate, but also adapts to diverse user needs and equipment characteristics, ensuring cross-device compatibility and real-time updates.

[0079] pass Figure 3It can be seen that the celestial body shooting plan provided in the embodiment of the present application not only takes into account the influence of the altitude angle of the celestial body on the image quality, but also takes into account meteorological factors (such as atmospheric transparency and cloud cover) to ensure the best conditions for shooting. The celestial body shooting plan method provided in the embodiment of the present application greatly simplifies the operation process of astronomical photography, allowing astronomy enthusiasts to shoot according to the generated shooting plan without complex calculations, thereby improving shooting efficiency and image quality, and is especially suitable for beginners and non-professional users.

[0080] Please see Figure 4 , Figure 4 The third flow chart of the celestial body photography planning method provided in the embodiment of the present application; in an optional embodiment, the photography parameters include the total photography time. In the above step S200, the photography plan of the target celestial body is generated according to the meteorological elements of the target position and the altitude angle information of the target celestial body, which can also be implemented by the following steps:

[0081] Step S221: determining a plurality of target time periods corresponding to the total shooting duration, and arranging the shootability scores of the plurality of target time periods in chronological order.

[0082] In the above step S221, it is assumed that the total shooting time is divided into two target time periods, which are target time period 1 and target time period 2 in chronological order. It is assumed that within the current total shooting time, the user wants to select star a and star b for shooting. Then the shootability scores of star a and star b are arranged in chronological order. For example:

[0083] The scores of star a in each target period are as follows:

[0084] Target time period 1 score 10,

[0085] Target time period 2 score 7.

[0086] The scores of each target period of star b are as follows:

[0087] Target time period 1 score 9,

[0088] Target time period 2 score 0.

[0089] Step S222: adding a second weight to the shootability scores of the multiple target time periods to obtain a recommended shooting plan.

[0090] Among them, the second weight shows a non-increasing trend as the time sequence of the target time period progresses.

[0091] In the above step S222, based on step S221, the shootability scores of the multiple target time periods are further processed and a second weight is added. The second weight is adjusted according to the time sequence of the target time periods and has a non-increasing trend.

[0092] The reason for adding a second weight in the embodiment of the present application is that when the shooting time of the same target celestial body continues to accumulate, the shooting effect will decrease marginally. In order to give users a shooting plan with better shooting effects as much as possible, the embodiment of the present application adds a second weight to the scores of different time periods.

[0093] The second weight can be the score Or, -kn , where k is the attenuation coefficient, n increases as the target period progresses, and as n increases.

[0094] The second weight is the score For example, for target time period 1, the second weight is the score Target time period 2 The second weight is the score Specifically as follows:

[0095] The scores of star a in each target period are as follows:

[0096] Target time period 1 score 10,

[0097] Target Time Period 2 Scoring

[0098] The scores of each target period of star b are as follows:

[0099] Target time period 1 score 9,

[0100] Target time period 2 score 0.

[0101] Then, according to the above results, target time period 1 will recommend star a to the user as the target shooting object, and target time period 2 will recommend star a to the user as the target shooting object. However, in the embodiment of the present application, considering that star b has a higher score (9 points) in target time period 1, but its score in target time period 2 is 0, it is possible to consider placing star b in target time period 1 for shooting, and recommend shooting star a in target time period 2. This can not only avoid the marginal effect caused by accumulating too much time on the same target celestial body, but also ensure that multiple target celestial bodies are shot, thereby improving the overall shooting quality.

[0102] pass Figure 4 It can be seen that by reasonably selecting the shooting time periods for different targets and taking into account the marginal diminishing effect, the final shooting plan ensures that the shooting quality of multiple targets in their respective best time periods is maximized, while avoiding excessive concentration on a certain target. In the case of dealing with multiple shooting objects, reasonable time arrangements are made to ensure the balance of the overall shooting effect. It can be seen that the shooting plan provided in the embodiment of the present application can not only improve the efficiency of shooting, but also ensure that the shooting quality of multiple target celestial bodies is maintained at a high level.

[0103] Please see Figure 5 , Figure 5 The fourth flow chart of the celestial body photography planning method provided in the embodiment of the present application; in an optional embodiment, after the photography plan of the target celestial body is generated in the above step S200, the celestial body photography planning method provided in the embodiment of the present application further includes the following steps:

[0104] Step S300: When the preset shooting time is reached, the shooting device is controlled to switch from the standby mode to the working mode.

[0105] In the above step S300, when the preset shooting time is reached, the control device is switched from the standby mode to the working mode to prepare for shooting. For example, if the shooting work starts at time C in the shooting plan, when time C is reached or about to be reached, the device will automatically wake up and switch from the standby mode to the working mode.

[0106] Step S400: In working mode, real-time meteorological elements of the target location are obtained.

[0107] In the above step S400, in the working mode, the real-time meteorological elements of the target location are obtained again. The real-time meteorological data can help ensure the suitability of the shooting conditions, such as the impact of environmental factors such as clouds, wind speed, humidity, etc. that are changing at any time on the shooting effect. For example, if the weather forecast shows that there are more clouds at this location during this time period, the shootability will be recalculated and the shooting plan will be dynamically adjusted to take into account the impact of meteorological changes on celestial body shooting.

[0108] Step S500: When the real-time meteorological elements meet the preset shooting requirements, the shooting equipment is controlled to perform shooting according to the shooting plan of the target celestial body.

[0109] In the above step S500: when the preset shooting requirements are met, the device starts working according to the established shooting plan. At this time, the shooting device will shoot according to the shooting plan generated in step S200, and can push the shooting plan to the user, who can confirm or adjust it to ensure that the plan is consistent with the actual needs.

[0110] Optionally, after being pushed to the user, user feedback is continuously received, including user confirmation information, or user adjustments to the shooting plan, to ensure that the user can make corresponding adjustments based on actual conditions.

[0111] After the user confirms, the shooting device will start to execute the plan. If the user no longer wants to continue, he can exit the shooting task (abandon the plan). It should be noted that in order to ensure that the execution of the shooting plan will not affect the final effect due to constant changes, the user cannot modify the shooting plan while it is in progress.

[0112] Optionally, you can edit the shooting plan except the current shooting process (i.e., the shooting plan being exposed). That is, if the shooting task has not yet entered the current actual exposure stage, that is, the shooting process is not in progress, the user can edit and adjust the shooting plan accordingly. Allow the user to make reasonable adjustments according to the actual situation (such as weather changes, equipment status, etc.) to optimize the shooting strategy.

[0113] pass Figure 5 It can be seen that the celestial body photography planning method provided in the embodiment of the present application not only ensures that the device automatically executes the photography plan, but also provides real-time meteorological data support to ensure that the conditions during the photography process always meet the preset requirements; at the same time, it allows users to make adjustments before the plan is executed, thereby enhancing the user experience.
