Preferred embodiment of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other. Additionally, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The object motion trajectory shooting method and system according to the embodiment of the present invention does not rely on the imaging hardware for long-time exposure, but uses image synthesis technology to simulate long-time exposure, and adjusts parameters such as ISO, picture quality, and scene mode according to the requirements of the shooting scene. And the limitation, the parameter is output to the hardware device, then the image is acquired for image synthesis, and the composite image is encoded to generate a video file, and finally the object motion track video and the object motion track image are captured. The following embodiments of the present invention take a shooting star track as an example for detailed description, but are not limited to shooting a star track, and are also suitable for other similar scenes, such as shooting a moon trajectory.

An embodiment of the present invention provides a method for photographing an object motion trajectory. Referring to FIG. 1 , in an embodiment, the method for photographing an object motion trajectory includes:

Step S10, the first photographing terminal photographs an object motion trajectory;

In this embodiment, the object motion trajectory shooting method is mainly applied to a mobile terminal having a shooting function to perform star track (object motion trajectory) shooting; specifically, the first shooting terminal may be a mobile terminal having a shooting function, such as a smart phone, a PAD Wait. The first photographing terminal has a star track photographing function. When in use, the star photographing function of the first photographing terminal is first turned on, and the first photographing terminal is controlled to enter a star track photographing state (ie, the object motion locus photographing state). In this embodiment, the object motion is substantially relative to the captured mobile terminal, and the motion type may include the following three situations: 1. The state of the object is motion, the state of the mobile terminal is static; and the state of the object is At rest, the state of the mobile terminal is motion; third, the state of the object and the mobile terminal are the same, but the relative position changes.

Step S20, when the interrupt request is detected during the shooting, the first photographing terminal sends a photographing request to the second photographing terminal according to the interrupt request, and sends the object motion track data generated by the current photographing to the Second, the terminal is photographed to cause the second photographing terminal to continue shooting, and generate an object motion trajectory image or video.

After the first shooting terminal enters the star track shooting state, it is determined in real time whether the preset condition is reached. When the preset condition is reached, the corresponding application will generate an interrupt request to the background server to interrupt the shooting of the first shooting terminal.

It can be understood that the preset condition generated by the above interrupt request can be set according to actual needs, for example, an interrupt request can be generated according to the power; the interrupt operation can be actively input by the user, and an interrupt request is generated (for example, for using the first photographing terminal) When you need to pause the shooting of the first shooting terminal, The interrupt operation may be input to the first photographing terminal, and the interrupt request may be generated by the corresponding application program in the first photographing terminal; and the interrupt request may be generated by other preset conditions. Specifically, in this embodiment, after performing step S10, the method further includes:

The first photographing terminal detects the electric quantity value in real time

The first preset value may be a fixed value manually set by the user, or may be calculated according to the star track data generated by the first shooting terminal to ensure that all the star track data generated by the first shooting terminal can be sent to the The second shooting terminal.

When the first photographing terminal acquires the interrupt request, the first photographing terminal sends a photographing request to the second photographing terminal according to the interrupt request, and sends the star track data (ie, the object motion track data) generated by the current photographing to the The second shooting terminal. It can be understood that the above-mentioned star-track shooting includes star-track image shooting and/or star-track video shooting. The following describes the star-track image shooting and the star-track video shooting separately.

When the star-track image is captured, the first photographing terminal may take a star-track trajectory by the following photographing method to form a star-track image: the first photographing terminal sets the first image captured by the photographing as an image to be composited; After obtaining the first image, an image is acquired every preset time; each time an image is acquired, the currently acquired image is combined with the image to be combined to form a new composite image, and the The new composite image is set as the image to be composited for the next image synthesis. When the shooting is completed, the last image to be composited is set as the star track image. For example, the camera captures an image every preset time, and the preset time is equivalent to the exposure time, preferably 5 to 10 seconds. If the first image has been taken, then the first image is the image to be composited, and when the second image (the current image) arrives, the corresponding position of the first image and the second image is Pixels are compared. If the brightness of the second picture is greater than the brightness of the first picture, the pixels of the second picture are extracted to replace the pixels corresponding to the position of the first picture, and finally a composite image is obtained, and then This composite image is the image to be composited, and the subsequent image is subjected to the same processing, and finally a star-track composite image is obtained. The interrupt request is generated before the shooting is completed. When the interrupt request is detected, the first photographing terminal sets the currently captured image to be combined as the star track data, and sends the image to the second photographing terminal.

When the star-track image is captured, the first photographing terminal can also capture the star-track trajectory by the following photographing method to form a star-track image: the first photographing terminal sets the first image captured by the photographing as an image to be composited; After acquiring the first image, collecting an image every preset time, and storing the collected image in a preset storage area according to the sequence of acquisition; sequentially reading the image in the preset storage area Each time an image is read, the currently read image is image-combined with the image to be composited to form a new composite image, and the new composite image is set as the next image. The synthesized image to be synthesized. When the shooting is completed, the last image to be composited is set as the star track image. The interrupt request is generated before the shooting is completed. When the interrupt request is detected, the first photographing terminal sets the currently captured image to be combined as the star track data, and sends the image to the second photographing terminal.

When the star-track video is captured, the first photographing terminal can capture the star-track track by the following photographing method to form a star-track video: the first photographing terminal sets the first image captured by the photographing as an image to be composited; After obtaining the first image, an image is acquired every preset time; each time an image is acquired, the currently acquired image is combined with the image to be combined to form a new composite image, and the The new composite image is set as the image to be composited for the next image synthesis; the image to be composited is captured, and the captured image to be composited is encoded to obtain image encoded data; when the shooting is completed, it will be based on all Image encoded data is synthesized into a video file. The interrupt request is generated before the shooting is completed. When the interrupt request is detected, the image to be synthesized and all the image encoded data are set as star track data; or the interrupt is detected. When requested, the video file is synthesized based on all the image encoded data, and the image to be synthesized and the video file are set as star track data.

When the star-track video shooting is implemented, the first photographing terminal can also capture the star-track track by the following photographing method to form a star-track video: the first photographing terminal sets the first image captured by the photographing as an image to be composited; After acquiring the first image, collecting an image every preset time, and storing the collected image in a preset storage area according to the sequence of acquisition; sequentially reading the image in the preset storage area Each time an image is read, the currently read image is image-combined with the image to be composited to form a new composite image, and the new composite image is set as the next image. Synthesized image to be composited; grab the image to be composited, and encode the captured image to be composited to obtain image encoded data; when the shooting is completed, according to all the images Synthesize video files like encoded data. The interrupt request is generated before the shooting is completed. When the interrupt request is detected, the image to be synthesized and all the image encoded data are set as star track data; or the interrupt is detected. When requested, the video file is synthesized based on all the image encoded data, and the image to be synthesized and the video file are set as star track data.

It can be understood that, when the star-track video capture is implemented, the manner of capturing the image to be composited may be set according to actual needs, for example, the image to be synthesized or the image of the interval to be composited may be continuously captured. Continuously capturing a composite image means that each time a composite image is generated, one image is captured for encoding, that is, all the images to be synthesized are generated as a material of the composite video. The generation of the image to be composited and the capture of the image to be combined for encoding are performed by two threads simultaneously. Since the composite image is encoded while being photographed, it is not necessary to store the generated image to be composited. Interval grabbing refers to selectively capturing a portion of an image to be composited as a material for a composite video. The interval mode can be a manual interval mode or an automatic interval mode. The manual interval mode refers to providing an operation interface for the user to click to trigger the captured image data, such as clicking the screen to capture the currently generated image to be composited; the automatic interval mode refers to capturing the image to be combined according to a preset time interval. That is, an image to be composited is captured every preset time.

In this embodiment, the second photographing terminal may continue to perform star track image shooting or star track video shooting according to the star track data transmitted by the first photographing terminal. The following is a detailed description of one of the shooting methods.

The second photographing terminal has a star track photographing function. When in use, the second photographing terminal turns on the star track photographing function after receiving the photographing request, enters a star track photographing state; and receives the image to be composited in the received star track data. (that is, the image to be combined sent by the first photographing terminal) is set as the image to be synthesized of the second photographing terminal; one image is collected every preset time; after the first image is acquired, one time is collected every preset time. An image; each time an image is acquired, the currently acquired image is combined with the image to be combined to form a new composite image, and the new composite image is set to be synthesized for the next image synthesis. Image to continue shooting. It should be noted that the manner in which the second photographing terminal performs the star-track photographing is the same as the manner in which the first photographing terminal performs photographing, and the difference is only that the first photographing terminal is different from the starting point photographed by the second photographing terminal. The first photographing terminal uses the first image photographed by the photographing terminal as the photographing starting point, and the second photographing terminal photographs the breakpoint of the first photographing terminal (ie, the image to be synthesized sent by the first photographing terminal) as a starting point.

In the embodiment of the present invention, when the interrupt request is detected, the first photographing terminal transmits the object motion trajectory data generated by the current photographing to the second photographing terminal, and simultaneously sends the photographing request to the second photographing terminal; thereby being The shooting request and the object motion trajectory data continue to be photographed to form an object motion trajectory image or an object motion trajectory video. Therefore, the embodiment of the invention realizes the function of the breakpoint continuous shooting to prevent the star track shooting time from being extended due to the interruption, thereby effectively shortening the time of the star track shooting and reducing the difficulty of the star track shooting.

Preferably, the above, so that the second photographing terminal continues to perform photographing, and generating an object motion trajectory image or video includes:

When the second photographing terminal is photographed, the second photographing terminal merges the object motion trajectory data respectively captured by the first photographing terminal and the second photographing terminal, and generates an object motion trajectory image; or The second photographing terminal synthesizes an object motion trajectory video according to the object motion trajectory data generated by the first photographing terminal and the second photographing terminal.

When the star-track image is captured, the second photographing terminal can capture the star-track track by the following photographing method to form a star-track image: after the second photographing terminal receives the photographing request sent by the first photographing terminal, enters the star track shooting After the state, the image to be synthesized in the received star track data is set as the image to be combined of the second photographing terminal; the image to be combined in the received star track data is set as the image to be combined of the second photographing terminal After the second photographing terminal receives the photographing request sent by the first photographing terminal, an image is collected every preset time; after the first image is acquired, an image is collected every preset time; When an image is obtained, the currently acquired image is combined with the image to be composited to form a new composite image, and the new composite image is set as the image to be composited for the next image synthesis; when the shooting is completed After that, the image to be synthesized which is finally set is used as a star track image (that is, the object motion track image described above). It can be understood that the star track image shooting or the star track video (object motion track video) shooting can also be performed according to other shooting modes. For the specific shooting principle, reference may be made to the foregoing, and details are not described herein again.

The first photographing terminal 100 is adapted to photograph an object motion trajectory; when an interrupt request is detected during photographing, the first photographing terminal 100 sends a photographing request to the second photographing according to the interrupt request The terminal 200 transmits the object motion trajectory data generated by the current shooting to the second photographing terminal 200;

In this embodiment, the object motion trajectory photographing system is mainly applied to a mobile terminal having a photographing function for star-track shooting; specifically, the first photographing terminal 100 may be a mobile terminal having a photographing function, such as a smart phone, a PAD, or the like. The first photographing terminal 100 has a star track photographing function. When in use, the star photographing function of the first photographing terminal 100 is first turned on, and the first photographing terminal 100 is controlled. Enter the star track shooting status. In this embodiment, the object motion is substantially relative to the captured mobile terminal, and the motion type may include the following three situations: 1. The state of the object is motion, the state of the mobile terminal is static; and the state of the object is At rest, the state of the mobile terminal is motion; third, the state of the object and the mobile terminal are the same, but the relative position changes.

After the first shooting end 100 enters the star track shooting state, it is determined in real time whether the preset condition is reached. When the preset condition is reached, the corresponding application will generate an interrupt request to the background server to interrupt the shooting of the first shooting terminal 100. .

It can be understood that the preset condition generated by the above interrupt request can be set according to actual needs, for example, an interrupt request can be generated according to the power; the interrupt operation can be actively input by the user, and an interrupt request is generated (for example, for using the first photographing terminal) At 100 o'clock, it is necessary to suspend the photographing of the first photographing terminal 100, so that an interrupt operation can be input to the first photographing terminal 100, and an interrupt request is generated by a corresponding application program in the first photographing terminal 100; and can also be generated by other preset conditions. Interrupt the request. Specifically, in this embodiment,

The first photographing terminal 100 is further configured to detect the electric quantity value in real time; and when the electric quantity value of the first photographing terminal 100 is less than the first preset value, the first photographing terminal 100 generates the interrupt request.

After acquiring the first image, collecting an image every preset time, and storing the collected image in a preset storage area according to the sequence of acquisition; sequentially reading the preset storage area An image; each time the image is read, the currently read image is image-combined with the image to be composited to form a new composite image, and the new composite image is set to be lower Image to be synthesized in one image synthesis; captures the image to be composited, and performs encoding processing on the captured image to be composited to obtain image encoded data; when the shooting is completed, the video file is synthesized according to all the image encoded data. The interrupt request is generated before the shooting is completed. When the interrupt request is detected, the image to be synthesized and all the image encoded data are set as star track data; or the interrupt is detected. When requested, the video file is synthesized based on all the image encoded data, and the image to be synthesized and the video file are set as star track data.
