Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The panoramic shooting scheme can acquire images at various angles such as up, down, left, right, front and back, and realize three-dimensional non-dead-angle omni-directional panoramic shooting based on the azimuth parameters during image acquisition, so as to finally obtain the omni-directional panoramic image. It should be understood that the execution subject of the panoramic shooting scheme according to the embodiment of the present invention may be a mobile terminal with a camera function, for example, a mobile phone, a tablet computer, an intelligent wearable device, and the like.

Referring to fig. 1a, a schematic step diagram of a panoramic shooting method provided in an embodiment of the present invention is shown, where the panoramic shooting method is applied to a mobile terminal, and mainly includes the following steps:

step 101: the mobile terminal acquires orientation parameters when images are acquired under the condition of panoramic shooting, and synthesizes the acquired images into panoramic images according to the orientation parameters.

The panoramic shooting is that an image pickup device serving as a shooting subject is in a panoramic shooting mode, and in the panoramic shooting mode, images of a shooting scene can be collected based on any direction.

It should be understood that the orientation parameters according to the embodiments of the present invention are determined based on the shooting position or the shooting angle of the camera device when the image is captured.

Step 102: and determining whether to output the panoramic image according to the integrity value of the synthesized panoramic image.

In the embodiment of the invention, the acquired images are synthesized into the panoramic image through the orientation parameters during the acquisition of the images, and whether the panoramic image is output or not is determined based on the integrity value of the synthesized panoramic image. And then, realizing the synthesis of the panoramic image based on the orientation parameters, and realizing the output of the omnidirectional panoramic image based on the integrity value of the synthesized panoramic image. Therefore, the three-dimensional dead-angle-free omnibearing panoramic shooting can be quickly and accurately realized.

It should be understood that, in the present invention, outputting a panoramic image includes: and transmitting the panoramic image to other equipment or displaying the panoramic image on a mobile terminal.

Optionally, step 101 specifically includes: and according to the orientation parameters when the images are collected, sequentially adding the collected images to the target positions, which are the same as the orientation parameters, in the panoramic image shooting template to synthesize the panoramic image.

Here, the panoramic image capture template may be a panoramic image capture template related to orientation parameters, which is preset to realize an omnidirectional panoramic image, and includes a plurality of target positions to each of which an image having the same orientation parameters as those of the target positions can be added. Therefore, the panoramic image can be more accurately synthesized based on the preset panoramic image shooting template and the orientation parameters.

Based on the technical solution of step 101, the following two specific implementation manners can be referred to:

the first method is as follows:

and acquiring a plurality of images, sequentially adding the acquired images to target positions in a panoramic image shooting template, which are the same as corresponding orientation parameters, according to the orientation parameters when each image in the plurality of images is acquired, and synthesizing the panoramic image. The method can collect the images firstly and then synthesize all the collected images into the panoramic image, so that the requirement on a processor is low and the synthesis scheme is more accurate.

The second method comprises the following steps:

acquiring an image, adding the image to a target position in a panoramic image shooting template, which is the same as the orientation parameter, according to the orientation parameter of the image, then acquiring a next image, adding the next image to a target position in the panoramic image shooting template, which is the same as the orientation parameter of the next image, according to the orientation parameter of the next image, sequentially and circularly acquiring and adding the images in all the orientations, and synthesizing the panoramic image. The method can synthesize the image into the panoramic image shooting template after one image is collected, and does not need to wait until all the images are collected and then synthesize, so that certain processing time is saved, and the synthesis scheme is more efficient.

Optionally, in the embodiment of the present invention, the omnidirectional panoramic image should be complete, but in consideration of the existence of the shooting error and the synthesis error, the synthesized panoramic image may have a few image deletions without affecting the overall effect of the omnidirectional panoramic image, and therefore, whether the omnidirectional panoramic image can be output or not may be determined by the relationship between the integrity value of the synthesized panoramic image and the preset threshold. Then, referring to fig. 1b, step 102 may specifically include:

step 1021: and judging whether the integrity value of the synthesized panoramic image is greater than a preset threshold value.

It should be understood that the completeness value of the synthesized panoramic image may be an index indicating whether the panoramic image is an omnidirectional panoramic image; the preset threshold may be a value set according to an empirical value or a processing capability of the processor.

According to the ratio of the vacant target position in the panoramic image shooting template to the panoramic image shooting template, assuming that A is a numerical value smaller than 1, and the integrity value of the synthesized panoramic image can be represented by 1-A.

According to another realizable scheme, the number B of the orientation parameters corresponding to the target position in the panoramic image shooting template is hit according to the orientation parameters in the synthesized panoramic image, and the integrity value of the synthesized panoramic image can be represented by B.

In fact, a preferred implementation of step 1021 is to determine whether the synthesized panoramic image is complete, that is, whether images are added to all target positions of the panoramic image shooting template.

Step 1022: and if the output value is larger than a preset threshold value, determining to output the panoramic image.

And if the integrity value of the synthesized panoramic image is greater than a preset threshold value, determining to output the omnidirectional panoramic image. In addition, the omnibearing panoramic image can be displayed on the display interface or stored.

Through the steps 1021 to 1022, whether to output the omnidirectional panoramic image can be determined based on the integrity value of the synthesized panoramic image, so that the omnidirectional panoramic image can be flexibly controlled to be output, and the omnidirectional panoramic shooting effect is improved.

Optionally, the three-dimensional data acquired by the gyroscope of the mobile terminal is used as the orientation parameter when the image is acquired, that is, the three-dimensional data of the space where the mobile terminal is located is acquired through the gyroscope arranged inside the mobile terminal. Preferably, the three coordinate parameters of XYZ in the space rectangular coordinate are used for representing, the mobile terminal shoots in different directions, and the values of the three coordinate parameters of the gyroscope are different accordingly. The orientation of the mobile terminal can be positioned through the three-dimensional data of the gyroscope, and then the panoramic image can be synthesized according to the orientation parameters and whether the omnidirectional panoramic image is output or not can be determined.

In fact, besides the three-dimensional data, the shooting angle of view when the image is collected may be used as the orientation parameter, which is not limited in the embodiment of the present invention.

Optionally, in the embodiment of the present invention, as shown in fig. 1c, the method further includes:

step 103: and smoothing the joint position of the panoramic image.

Wherein the smoothing process includes at least: a registration process and/or a blurring process. The registration process is mainly directed to a small number of repeated images, especially repeated parts at the splice locations; the blurring process is mainly directed to a small number of missing images, especially missing parts at the splice location.

It should be understood that in the embodiment of the present invention, the smoothing process is not only performed after step 101, but also performed after any image synthesis process is completed. The smooth processing can eliminate the image connection defect caused by repetition and deletion at the connection position of the image, so that the omnibearing panoramic image is more real and natural, and the image synthesis effect is improved.

The technical solution of the present invention is described in detail by specific embodiments with reference to fig. 2 a.

Step 201: in the case of panoramic photography, images of a photographic scene are acquired.

Here, it is determined that the mobile phone is an execution subject of the panorama shooting method, and the mobile phone may acquire an image of a shooting scene through the front camera or the rear camera in a second manner.

In the embodiment of the present invention, the image carries: image information and three-dimensional data; correspondingly, referring to fig. 2b, step 201 may specifically include:

step 2011: and acquiring image information of a shooting scene under the panoramic shooting condition.

It should be understood that the image information refers to content related to the scene image.

Step 2012: and acquiring the three-dimensional data of the mobile phone when the image information is acquired.

Specifically, three-dimensional data representing the orientation of the mobile phone can be obtained through detection of a gyroscope sensor in the mobile phone, and the three-dimensional data can be replaced by other orientation parameters.

Step 2013: adding the three-dimensional data markers to an image in the image information.

In fact, the three-dimensional data and the image information can be added into the image to obtain the collected image. Or marking the three-dimensional data in the image information, and then adding the image information marked with the three-dimensional data to the image to obtain the acquired image. The embodiment of the present invention is not limited to this, and the image information may be added to the three-dimensional data.

Step 202: and synthesizing the acquired images into a panoramic image according to the orientation parameters when the images are acquired.

The step is realized in a mode two corresponding to the method, namely, the images are immediately synthesized into the panoramic image shooting template after being collected.

Step 203: and judging whether the integrity value of the synthesized panoramic image is greater than a preset threshold, if so, executing the step 204, otherwise, skipping to the step 201.

Step 204: an output panoramic image is determined.

The mobile phone judges whether the value of the integrity of the synthesized panoramic image is larger than a preset threshold value or not according to the value of the integrity of the synthesized panoramic image, if the value of the integrity of the synthesized panoramic image is larger than the preset threshold value, the synthesis of the image is complete, the omnidirectional panoramic image can be displayed or stored, if the value of the integrity of the synthesized panoramic image is not larger than the preset threshold value, the image is absent (the absence is explained as large-range image absence and should be distinguished from small-range image absence at a joint gap), and the previous steps are required to be returned to continue to collect the synthesized panoramic image until the value of the integrity of the synthesized panoramic image is larger than the preset threshold value (namely the image is completely synthesized). Therefore, whether scenes which are not shot exist can be judged based on the integrity value of the synthesized panoramic image, image loss caused by the fact that the scenes are not shot at a certain azimuth angle is prevented, and accuracy of shooting the omnibearing panoramic image is improved.

An embodiment of the present invention further provides a mobile terminal, and as shown in fig. 3a, the mobile terminal mainly includes:
