Specifically, the embodiments of the present invention will be further explained below with reference to the drawings.

Example one

An embodiment of the present invention provides a method for acquiring an image including stars, which can be applied to the mobile terminal 10 in the above application scenario, please refer to fig. 2, which shows a flow of the method for acquiring an image including stars according to the embodiment of the present invention, where the method includes, but is not limited to, the following steps:

step 110: acquiring an initial starry sky image shot by the mobile terminal and azimuth information when the initial starry sky image is shot by the mobile terminal;

in the embodiment of the present invention, first, an initial starry sky image shot by the mobile terminal and azimuth information when shooting the initial starry sky image need to be obtained, where the initial starry sky image is an image of a currently visible sky shot by a mobile terminal currently used by a user, and the image may include a starry or no starry and is an initial image that needs to be processed. The azimuth information comprises the geographic position and the shooting direction of the mobile terminal and comprises the information of the starry sky shot by the user at present.

Step 120: acquiring a superposed image according to the azimuth information;

in the embodiment of the present invention, after obtaining an initial starry sky image shot by the mobile terminal and its azimuth information, that is, an initial starry sky image shot by the mobile terminal at the current geographic location and in the current shooting direction, a superimposed image shot by other terminal devices shooting the same starry sky may be further obtained according to the azimuth information, specifically, refer to fig. 3, which shows a sub-process of step 120 in the method shown in fig. 2, where obtaining the superimposed image according to the azimuth information includes:

step 121: searching other terminal equipment in a preset range around the geographical position of the mobile terminal according to the geographical position of the mobile terminal;

in the embodiment of the present invention, in a preset range of the mobile terminal, a target starry sky image including stars captured by another terminal device is required to be obtained, the another terminal device is an electronic device capable of capturing or storing the target starry sky image including stars in a device album, and a user of the another terminal device may actively upload the target starry sky image including stars or upload the target starry sky image including stars according to a requirement, or send a request for obtaining the target starry sky image including stars to the mobile terminal and then feed back the target starry sky image to the mobile terminal, for example, the target starry sky image may be a mobile terminal 10b and a mobile terminal 10c shown in the above application scenario, and specifically, the target starry sky image including stars may be set according to an actual requirement.

Generally, because the air quality of suburbs around a city is good, more stars can be observed at night, the preset range can be set according to the size of the city where the mobile terminal is located, and a range larger than the area of the city where the mobile terminal is located is selected as the preset range, so that target starry sky images shot or stored by other terminals in the suburb range around the city are obtained as much as possible, and the sky is restored as much as possible.

Step 122: and screening the terminal equipment in the same shooting direction as the mobile terminal from the other terminal equipment, and acquiring the image shot by the terminal equipment in the same shooting direction to obtain the superposed image.

In the embodiment of the present invention, limited by the viewing angle of the mobile terminal, the image captured by the mobile terminal has a certain directionality and a certain limitation, and only a certain azimuth of the top of the head of the user or a certain sky in a certain field of view can be captured, in order to ensure that the sky included in the superimposed image captured by other terminal devices is the same sky as or coincides with the image captured by the mobile terminal, it is further necessary to screen terminal devices in the other terminal devices that have the same capturing direction as the mobile terminal, specifically, the capturing direction of the mobile device may be determined by parameters acquired by a gyroscope and a compass on the mobile device, and similarly, the capturing direction of the other terminal devices may also be acquired by this method.

In addition, since the positions of the stars may change with the passage of time, target starry sky images including stars acquired by other terminals in the same time period may also be acquired, for example, target starry sky images captured by other terminal devices in the current week may be acquired as images for processing superimposition with the same time period in the current week.

Step 130: fusing the superposed image with the initial starry sky image to obtain a target starry sky image;

and the star point information contained in the initial star field image is more than the star point information contained in the target star field image. The star point information includes relative positions of stars and brightness levels. In the embodiment of the invention, after the superposed image with more star point information than the initial starry sky image is obtained, the superposed image and the initial starry sky image can be fused to obtain the target starry sky image.

Referring to fig. 4, which shows an example of an image fusion process in the method for acquiring an image including stars according to an embodiment of the present invention, as shown in fig. 4, an initial starry sky image captured by a user through a mobile terminal is an image b, and due to the existence of fog and clouds, some stars with lower brightness in the initial starry sky image b cannot be observed, and the brightness of observable stars is also lower. The obtained superposed image a containing more star point information shot by other terminal equipment is assumed to be a suburban image, and a clear image containing most stars can be obtained without cloud occlusion.

The number of the target starry sky images including the stars, which are acquired by the other terminal devices, may be more than one, and the number of the other terminals may also be more than one, specifically, the number may be set according to actual needs, and the limitation of the embodiment of the present invention is not required.

Specifically, referring to fig. 5, it shows a sub-process of step 130 in the method shown in fig. 2, where the fusing the overlay image and the initial starry sky image to obtain the target starry sky image includes:

step 131: extracting relative positions of stars and brightness levels of stars in the superposed image and the initial starry sky image to obtain starpoint information of the superposed image and the initial starry sky image;

specifically, coordinates of each star in the superposed image and the initial starry sky image in the image are obtained, and the relative position of each star in the superposed image and the initial starry sky image is determined according to the coordinates; and acquiring the pixel value of each star in the superposed image and the initial starry sky image to obtain the brightness level of each star in the superposed image and the initial starry sky image.

In the embodiment of the present invention, still taking fig. 4 as an example, it is necessary to obtain the relative position of each star in the superimposed image a, mark each star with a brightness level, obtain the relative position of each star in the initial starry sky image b, and mark each star with a brightness level, so as to match the position and brightness of each star in the image b captured by the mobile terminal and fuse the position and brightness with the initial starry sky image b.

Step 132: and superposing the star point information in the superposed image on the initial starry sky image to obtain the target starry sky image.

After the star point information in the superimposed image is obtained, further specifically, please refer to fig. 6 together, which shows a sub-process of step 132, where superimposing the star point information in the superimposed image on the initial star field image to obtain the target star field image specifically includes:

step 1321: comparing the positions and the brightness of the stars in the initial starry sky image and the superposed image, and determining the superposed positions and the superposed sizes of the stars;

in the embodiment of the present invention, still taking fig. 4 as an example, since the stars that can be captured in the initial starry sky image b can be determined to be the stars with higher brightness, a certain number of stars with higher brightness levels can be selected according to the brightness levels of the stars in the superimposed image a, and the relative positions of the stars are compared with all the stars captured in the initial starry sky image b, so as to determine the positions of the stars that need to be superimposed in the initial starry sky image b. Meanwhile, generally, in the photo, the bigger the star is, the brighter the star is, so the size of the star to be superimposed in the initial starry sky image a is also determined according to the brightness level difference of each star in the superimposed image a. Further, if the brightness of the stars in the initial starry sky image a is low, the brightness of the stars in the initial starry sky image, that is, the size of the stars, may also be appropriately adjusted.

Step 1322: and according to the superposition position and size, combining the relative positions of the stars in the initial starry sky image and the brightness levels of the stars, and superposing the stars in the initial starry sky image to obtain the target starry sky image.

After determining the position of the stars to be superimposed according to the relative positions of the stars with higher brightness and determining the size of the stars to be low-priced according to the brightness levels of the stars in the superimposed image a, as shown in fig. 4, the stars are superimposed on the initial starry sky image b to obtain a target starry sky image c containing the stars, and the target starry sky image c is output so that the user of the mobile terminal can observe the stars through the mobile terminal.

In some embodiments, please refer to fig. 7 and fig. 8 together, fig. 7 is an image erasing flow in the method for acquiring an image including stars according to the embodiment of the present invention, fig. 8 is an image erasing process in the method for acquiring an image including stars according to the embodiment of the present invention, before the overlaying image and the initial starry sky image are fused to obtain the target starry sky image, the method further includes the following steps:

step 141: receiving an erasing instruction issued by a user;

step 142: judging whether the initial starry sky image contains a cloud or not;

step 143: and if so, removing the clouds in the initial starry sky image according to the erasing instruction.

Wherein the removing the clouds in the initial starry sky image according to the erasing instruction comprises: determining an erasing position and corresponding erasing times in the initial starry sky image according to the erasing instruction; and adjusting the brightness of the erasing position in the initial starry sky image according to the erasing times so as to remove the cloud in the initial starry sky image.

In the embodiment of the present invention, further, as shown in fig. 4, in the acquired superimposed image a captured by the other terminal, it is also possible to capture a star which is occluded by the cloud in the initial starry sky image b captured by the mobile terminal, so as to avoid that the occlusion of the cloud affects the observation of the user, a function of erasing the cloud may be further provided. As shown in fig. 8, the user may perform an erasing operation through an application program capable of executing the method for acquiring an image including stars according to the embodiment of the present invention, erase the clouds in the dashed box shown in fig. 8, and superimpose the brightness and the position of the stars in the dashed box position acquired in the initial starry sky image a on the erased image, thereby implementing the function of displaying after erasing.

The method comprises the steps of shooting a cloud, wherein the cloud is shot at night, and the shot initial starry sky image is a night scene image, wherein the sky is dark blue or black in the night scene image, and the cloud is a white object with certain transparency, so that when the mobile terminal erases the cloud, the brightness degree of the erasing position can be directly adjusted, and when a large-area white pixel, namely the cloud, is detected to exist in the erasing position, the blue or black of the erasing position is deepened, so that the original sky pattern is displayed, and then the stars are superposed. The brightness of the sky background and the brightness of the stars at the erasing position can be further adjusted according to the number of times of erasing actions performed by the user, and the darker the sky background and the brighter the stars are when the number of times of erasing is more, until a set limit value is reached, so that the image presents more changes.

It should be noted that, the erasing function may be implemented before the superimposing star generates the target starry sky image containing the stars, and/or after the superimposing star generates the target starry sky image containing the stars, and specifically, the erasing function may be set according to actual needs.

In some embodiments, please refer to fig. 9 and fig. 10 together, where fig. 9 is a process of displaying a mark of a constellation in the method for acquiring an image including a star according to an embodiment of the present invention, and fig. 10 is a process of displaying a mark of a constellation in the method for acquiring an image including a star according to an embodiment of the present invention, the method further includes the following steps:

step 151: acquiring time information of the mobile terminal;

step 152: acquiring the relative positions of all stars in the target starry sky image;

step 153: determining a constellation appearing in the target starry sky image by combining the geographic position and the time information of the mobile terminal and the relative positions of all stars in the target starry sky image;

step 154: the constellation is marked and displayed.

In the embodiment of the invention, further, the constellation in the finally obtained target starry sky image d containing the stars can be identified, so that a user can observe the starry sky more easily, have more experiences about the starry sky and know more knowledge about the starry sky. Specifically, the latitude and longitude of the current location of the user may be obtained according to a Global Positioning System (GPS) loaded in the current mobile device of the user, so as to determine the accurate location information of the user, and obtain the current time information of the mobile terminal. And then, according to the astronomical map, combining the relative positions of all stars in the initial starry sky image after the superposition processing, determining a constellation appearing in the initial starry sky image through comparison, and marking and displaying the constellation.

For example, taking fig. 10 as an example, according to the positioning of the mobile device, determining a longitude and a latitude of the mobile device, then by comparing an astronomical map, determining the longitude and the latitude, where a star appearing in the initial starry sky image d corresponds to a position in the astronomical map, and then labeling a constellation in the initial starry sky image d according to a field angle of an image sensor in the current mobile terminal, thereby obtaining an image e with the marked constellation, where the image e marks a dragon seat (north celestial star seat) and a small bear seat.

It should be noted that the method for obtaining stars by combining the positioning of the mobile device and the astronomical map can also be applied to the method for obtaining star point information when the overlay image is not obtained in the step 110, and specifically, the method can be set according to actual needs and does not need to be limited by the embodiments of the present invention.
