Further, the guide information includes the viewing range of the sub-image and the number of shots of the sub-image, and the shooting of the sub-image can be facilitated according to the viewing range of the sub-image. And finally, displaying a target image of the celestial object synthesized according to the plurality of sub-images. The high-quality target image including the celestial object can be easily shot, and the shooting efficiency is improved.
The contents of steps 210-240 are described below:
first, step 210 is involved.
In the case where a celestial object is included in the shooting preview interface, the finder range of the celestial object is determined. Taking the galaxy arch bridge as an example, the viewing range of the galaxy arch bridge can be 180 degrees.
In one possible embodiment, time information of the shooting environment is obtained, and position information of the shooting environment is located; determining the Botelun dark space level of the shooting environment according to the time information and the position information; and displaying prompt information, wherein the prompt information is used for prompting the user whether the Borter dark space grade meets the shooting condition for shooting the celestial object.
Wherein, the Borter dark space grade is a classification method for measuring the night space brightness in astronomy photography. Due to the fact that the phenomenon of light pollution is increasingly serious, observation points which are dark enough are far away from cities, many amateur astronomical enthusiasts cannot conveniently arrive at the observation points, and therefore, the amateur astronomical enthusiasts cannot accumulate enough experience to judge sky brightness. Also, the visual ability and observation ability of individuals are different, and the length of observation time is also influenced. Based on the principle, the Botelun space division principle integrates various factors to enable the observation standard to be more uniform and accurate.
The bordetella level quantifies the observability of celestial bodies and the degree to which light pollution interferes with astronomical observations. The classification method is divided into 9 grades, from the darkest sky seen on the earth (grade 1), to the sky in the center of the flourishing city (grade 9). Generally, the 1-4 grades are suitable for shooting celestial objects such as the silver river.
Illustratively, receiving and responding to a first input (such as: Tibet, 2020-12-18, 9 o' clock. evening) of time information and position information for indicating a photographing environment, determining a Botelr dark space level (such as: level 3) of the photographing environment according to the time information and the position information; and displaying prompt information, wherein the prompt information is used for prompting the user that the Poulter dark space level of the shooting environment is suitable for shooting the celestial object, namely for prompting the user that the Poulter dark space level meets the shooting condition for shooting the celestial object.
As shown in fig. 3, the prompt information is used to prompt the user that the current bordetella level is 4 levels and is suitable for shooting celestial objects.
Thereby, the Boteler dark space level of the shooting environment is determined according to the time information and the position information; and then displaying prompt information for prompting the user that the Botelun dark space level of the shooting environment is suitable for shooting the celestial object. The method and the system not only can help the user to reasonably plan the shooting environment, but also can help the user to find a proper shooting environment.
In a possible embodiment, before step 220, the following steps may be further included:
acquiring astronomical data of the celestial object from a preset astronomical database; generating an augmented reality reference image according to astronomical data; and displaying the augmented reality reference image on a shooting preview interface.
The astronomical data of the celestial object can be checked in the astronomical website, or the astronomical data of the celestial object can be called through a three-party interface.
In addition, since the position and shape of most celestial objects (such as the silver river) are strongly correlated with time, the time slide bar can be adjusted to check the position and shape of the silver river at any time corresponding to the shooting position input by the user. The method and the device can facilitate a user to make a shooting plan and determine the optimal shooting time. Taking the silver river arch bridge as an example, the optimal shooting time can be automatically recommended according to the silver core rising angle, and the silver river arch bridge is shot more suitably when the silver core rising angle is 10-40 degrees.
And displaying the augmented reality reference image on the shooting preview interface, wherein the reference image is generated according to the acquired astronomical data of the celestial object from the preset astronomical database. Thus, the reference image may be used to characterize the objective morphology of the celestial object. Therefore, the augmented reality reference image is displayed on the shooting preview interface, and the composition position of the celestial object in the shooting preview interface can be determined according to the reference image, so that the shooting by a user is facilitated. Therefore, the augmented reality reference image generated according to the astronomical data of the celestial object is displayed on the shooting preview interface, the composition position of the celestial object in the shooting preview interface can be determined according to the reference image, a user can be helped to quickly determine the composition position, and the shooting efficiency is improved.
After the step of displaying the augmented reality reference image on the shooting preview interface, the method may further include the following steps:
receiving a first input; in response to the first input, transparency of the reference image is adjusted.
As shown in fig. 4, the transparency of the reference image (i.e. the virtual galaxy) can be adjusted by adjusting the slide bar in the shooting preview interface, that is, the fusion degree of the virtual galaxy and the real galaxy is adjusted. When the reference image is set as 100%, the transparency of the reference image reaches the minimum value, namely, a completely virtual silver river is displayed on the shooting preview interface; when the transparency of the reference image is set to 0%, the transparency of the reference image reaches the maximum value, namely, the shooting preview interface displays a completely real silver river.
Therefore, the transparency of the reference image is adjusted by receiving and responding to the first input, so that the virtual celestial object and the celestial object in the real shooting environment can be simultaneously displayed in the shooting preview interface, the comparison by a user is facilitated, and the reference and shooting based on the reference image by the user can be assisted.
The guidance information includes direction guidance information, and after the step of acquiring astronomical data of the celestial object from the preset astronomical database, the method may further include the following steps:
determining first orientation information of the celestial object according to the astronomical data; determining second orientation information of the camera according to the detected gyroscope information; and determining direction guide information according to the first direction information and the second direction information, wherein the direction guide information is used for guiding a user to adjust the position of the camera.
Since the determination of the photographing environment of the celestial object requires azimuth information in addition to time information and position information. A gyroscope is an angular motion detection device that uses a moment-of-momentum sensitive housing of a high-speed rotating body to sense angular motion about one or two axes orthogonal to the axis of rotation with respect to the inertial space. Second orientation information of the camera may be determined based on the detected gyroscope information.
Exemplarily, the first orientation information of the celestial object is determined to be the southeast orientation according to the astronomical data; determining second azimuth information of the camera to be in a south-pointing direction according to the detected gyroscope information; then, in order to shoot an angle suitable for shooting a celestial object, the user is required to hold the electronic device and turn the electronic device from south to south, i.e., rotate the electronic device 45 degrees counterclockwise (i.e., guidance information for guiding the user to adjust the azimuth direction of the camera).
The first orientation information of the celestial object is determined according to the astronomical data, and the direction guide information is determined according to the second orientation information of the camera determined by the gyroscope information, so that the user can be guided to adjust the position of the camera based on the direction guide information, the shooting by the user is facilitated, and the shooting efficiency is improved.
Next, step 220 is involved.
Before step 220, the following steps may be further included:
determining the shooting quantity of the sub-images according to the view finding range of the celestial body object, the field angle of the camera and the preset coincidence rate between every two adjacent sub-images;
and determining the view range of the sub-images according to the view range of the celestial object, the preset coincidence rate and the shooting quantity.
First, the shooting number of the sub-images can be determined according to the viewing range of the celestial object, the camera angle of view, and the preset coincidence rate between every two adjacent sub-images.
The Field of View (FOV) is an angle formed by two edges of an optical instrument, where a lens of the optical instrument is a vertex and an object image of a target to be measured can pass through the maximum range of the lens. The field angle may be determined based on the focal length of the camera. Exemplarily, in case of a vertical shot, the corresponding field angle of view of an equivalent 26mm camera is 80 °.
Specifically, the number of the sub-images to be photographed may be determined according to a viewing range of the celestial object, a camera angle of view, and a preset coincidence ratio between each adjacent two sub-images based on the following formula (1).
F*(1-C)*(N-2)＝G (1)
Wherein F is the camera viewing angle, C is the preset coincidence rate, and G is the viewing range; the data to be determined is the number of shots N of the sub-image.
Illustratively, taking a panoramic silver river arch bridge with a view range of a celestial object of 240 ° as an example, the vertical shooting is performed by using an equivalent main camera lens of 26mm, and the specific calculation process is as follows:
the corresponding camera field angle FOV of the equivalent 26mm camera is approximately equal to 80 degrees, if the equivalent is 60 percent, the equivalent 26mm camera is obtained by substituting the formula (1): 80 (1-60%). N (N-2) ═ 240, the number of images N in the subimages was calculated to be 9.5, and N was actually taken to be 10 (rounding up was performed for non-integer results to ensure yield). That is, when the predetermined overlap ratio between two sub-images is 60%, the required number of shots is about 10.
The corresponding camera field angle FOV of the equivalent 26mm camera is approximately equal to 80 degrees, if the equivalent is 50 percent, the equivalent 26mm camera is obtained by substituting the formula (1): 80 × 1 to 50% × (N-2) ═ 240, and the number N of shots of the sub-images was calculated to be 8. That is, in the case where the preset coincidence ratio between every two sub-images is 50%, the required number of shots is about 8.
For example, it is possible to display guide information including the number of shots on the shot preview interface and display that the currently shot sub-image is several in all the sub-images. As shown in fig. 5, the currently photographed sub-image is the 2 nd sub-image, and the total number of photographed sub-images is 8. The user is prompted to take the process conveniently.
Then, the finder range of the sub-image can be determined according to the finder range of the celestial object, the preset coincidence ratio, and the number of shots. For example, when the finder range of the subject is 180 °, the preset coincidence ratio is 50%, and the number of shots is 8, the finder range of the sub-image is X.
N X- [ X50%, (N-1) ], 180 °, gives X40 °.
Thus, the number of the sub-images taken, and the viewing range of the sub-images can be determined based on the viewing range of the celestial object, the camera angle, and the preset coincidence ratio between each adjacent two sub-images. The user only needs to press the shutter according to the guide information and can obtain many subimages, and the very big degree reduces the shooting degree of difficulty, promotes and shoots efficiency.
Next, step 230 is involved.
And shooting the celestial object according to the guide information to obtain a plurality of sub-images.
The user can shoot the celestial object according to the guide information in the shooting preview interface, and the sequence number of the currently shot sub-image, the moving direction of the next sub-image and the view finding range of the sub-image are displayed in real time in the shooting preview interface in the shooting process.
As shown in fig. 6, a dotted line with a double arrow indicates a viewing range of the sub-image, and the arrow indicates a moving direction in which the next sub-image is captured, i.e., a direction in which the user moves the electronic device.
In a possible embodiment, the multiple sub-images include at least a first sub-image and a second sub-image captured adjacently, and the step 230 may specifically include the following steps:
under the condition that a first sub-image is obtained through shooting, determining the coincidence rate of the first sub-image and a second sub-image corresponding to a preview picture; and shooting under the condition that the coincidence rate meets a preset condition to obtain a second sub-image, wherein the preset condition is determined according to the preset coincidence rate.
In order to ensure the synthesis effect, the coincidence rate of the first sub-image obtained by shooting and the second sub-image corresponding to the preview picture can be determined, and the shooting is carried out under the condition that the coincidence rate meets the preset condition, so that the second sub-image is obtained.
The preset condition is determined according to a preset coincidence rate, for example, when the preset coincidence rate is 50%, the preset condition may be that the coincidence rate of the first sub-image and the second sub-image corresponding to the preview screen is within a range of 40% to 60%.
Therefore, the second sub-image is obtained by shooting under the condition that the coincidence rate of the first sub-image and the second sub-image corresponding to the preview picture meets the preset condition, so that enough coincidence parts among a plurality of sub-images can be ensured, and the synthesis effect of a subsequent synthesis target image is improved.
Finally, step 240 is involved.
Before step 240, the following steps may also be included:
and carrying out panoramic synthesis, distortion correction, content identification, automatic cutting and exposure adjustment processing according to the multiple sub-images to obtain a target image.
Specifically, after the plurality of sub-images are shot, panoramic synthesis processing may be performed on the plurality of sub-images to obtain a first image, distortion correction processing may be performed on the first image to obtain a second image, content recognition and automatic cropping processing may be performed on the second image to obtain a third image, and exposure adjustment processing may be performed on the third image to obtain a target image.
The above-mentioned content recognition is that after panoramic synthesis processing is performed on a plurality of sub-images, distortion of the first image is large, and distortion correction needs to be performed on the first image, and usually, a partial blank appears at the edge of the second image obtained after the distortion correction processing, and automatic cropping processing needs to be performed on the obtained second image. Since the automatic cropping process may lose part of the picture, incorporating the content recognition fill process may achieve distortion correction without losing part of the picture.
Taking the celestial object as a galaxy arch bridge as an example, after synthesizing the target image, the target image is displayed as described in fig. 7. The target image of the galaxy arch bridge synthesized based on the multiple sub-images including the local galaxy can bring extremely shocking impression to people, and through the embodiment, the high-quality target image including the galaxy arch bridge can be shot quickly and efficiently without technologies such as abundant astronomical photographic knowledge and professional panoramic splicing of a user, so that the shooting efficiency is improved.
In summary, in the embodiment of the present application, when the shooting preview interface includes a celestial object, the guidance information is displayed on the shooting preview interface, and then the celestial object is shot when a picture in the shooting preview interface meets a preset condition, so as to obtain a plurality of sub-images. Since the guide information is determined according to the viewing range of the celestial object, shooting based on the guide information makes it possible to capture a plurality of sub-images that can be used to stitch together the entire view of the synthetic celestial object. Further, the guide information includes the viewing range of the sub-image and the number of shots of the sub-image, and the shooting of the sub-image can be facilitated according to the viewing range of the sub-image. And finally, displaying a target image of the celestial object synthesized according to the plurality of sub-images. The high-quality target image including the celestial object can be easily shot, and the shooting efficiency is improved.
