Target object carries out picture material compensation, obtains the multiple target object image.
In the present embodiment, the part of pending picture material compensation in the parallax and target object based on the second image
Angle information, match point can be searched on the corresponding virtual view of the angle information, obtain the corresponding pixel of the match point
Point content, is moved to the match point for the pixel content, so as to obtain the virtual view, i.e. target object image.Make
For another way, the coordinate information of the characteristic point of the target object in available multiple second images, based on acquisition
The coordinate information of the characteristic point of the target object of pending picture material compensation can be calculated in angle information, thus according to
The coordinate information of characteristic point is by the image completion of the target object of pending picture material compensatory zone, to obtain multiple targets
Subject image.
Step S350: being synthesized based on the multiple target object image and the multiple second image, is generated multiple
Third image.
In the present embodiment, it by carrying out picture material compensation to multiple second images based on preset algorithm, can obtain
Multiple target object images, wherein the corresponding visual angle of target object image includes the corresponding visual angle of multiple second images and more
Visual angle other than the corresponding visual angle of a second image.In some embodiments, it only includes difference that target object image, which can be,
The image of target object under angle can also synthesize multiple target object images and multiple second images, generate more
A third image, wherein it can be by choosing any one second image in multiple second images, and determine second image
The image in the region in the second image where target object is replaced in region where middle target object with target object image, from
And generate third image.Further, target object image can also be covered on to the area in the second image where target object
The image in domain, to generate third image.Above-mentioned synthesis mode is merely illustrative, is not intended as limiting.
In some embodiments, by multiple target object images either objective subject image and multiple second images
In any second image synthesized, the target object image and second image can be handled.It specifically, can be with
Obtain the target object image in the target object image fringe region and the second image correspond to position image color,
Edge, Texture eigenvalue calculate the similarity between feature, and judge whether similarity is greater than similarity threshold.Work as similarity
When greater than similarity threshold, where showing that the target object image is corresponding in the target object image fringe region and the second image
The features such as the color of the image of position are same or similar, then can synthesize the target object image with second image.Into one
Step ground, when similarity is less than threshold value, the target object in the adjustable target object image fringe region and the second image
Image corresponds to the characteristic parameters such as form and aspect, saturation degree, contrast, the brightness of the image of position, to increase the target object figure
As the target object image corresponds to the similarity between the image of position in fringe region and the second image, so that object
Display of the body image in the second image is more natural, style is consistent.
