The graphic objects can also be grouped, added with styles, transformed, combined, etc., and the feature set includes nested transformations (nesting transformations), clipping paths (clippingpaths), alpha masks (alphamasks), filter effects (filter effects), template objects (templateobjects), and other extensions (extensions).

In step S105, an adjustment operation is performed on the primitive data in the intermediate panoramic image based on the ratio data, so as to obtain a target panoramic image.
In the embodiment of the present application, since the primitive data sent by the user terminal is of a default size, the primitive data needs to be adjusted based on the actual proportion of the target scene, and the adjustment operation specifically may be: and scaling and adjusting the primitive data based on the frame size of the target scene and the size proportion of the object corresponding to the primitive data to be adjusted as reference, so that the object primitives consistent with the actual target scene can be obtained, and the panoramic image is ensured to be completely attached to the actual scene.
In step S106, the target panoramic image is output to the user terminal.

In some optional implementation manners of the first embodiment of the present application, the spherical image capturing apparatus is composed of at least 3 optical lens groups, the optical lens groups are uniformly distributed inside the spherical image capturing apparatus, and the focusing directions of the optical lens groups all point to the center of the sphere of the spherical image capturing apparatus.
In some optional implementations of the first embodiment of the present application, a connection line of central points of the lenses of the plurality of optical lens groups forms a largest equilateral shape or equilateral shape in the sphere.
In the embodiment of the application, the sphere camera device integrates n +1(n > ═ 2) optical lens groups which are uniformly embedded on the surface of the sphere device; all optical lens groups of the spherical camera device are ensured to share a shooting shutter control sensor, so that all the optical lens groups can shoot and collect optical signals at the same time; meanwhile, the manufacturing process of each group of optical lenses is uniform, so that the parameters such as refractive indexes of all the optical lenses are consistent, and the optical deviation rate of all the optical lenses is reduced to the minimum, so that the focus of each optical lens is concentrated at the spherical center of the spherical equipment.
In the embodiment of the application, the manufacturing process of each group of optical lenses is uniform, so that parameters such as refractive indexes of all the optical lenses are consistent, and the optical deviation ratios of all the optical lenses are reduced to the minimum, so as to ensure that the focal point of each optical lens is concentrated at the spherical center of the spherical equipment, namely the focal distance of the optical lens is approximately equal to the radius length of the spherical equipment.
In some optional implementation manners of the first embodiment of the present application, the step S101 further includes: adjusting a white balance parameter of the sphere photography apparatus.
In the embodiments of the present application, as research progresses, standardization of a panoramic image has become a necessary process for ensuring image sharpness. However, the inventors have realized that panoramic scan imaging is associated with many factors, such as the model of the slide scanner, which can cause color structure differences in the panoramic image.
In the embodiment of the present application, in order to unify the standard of panoramic scanning imaging, the white balance parameter may be adjusted for the spherical imaging apparatus. White balance is also understood as white balance, and here means that a slide glass not carrying a sample is placed under a sphere imaging device in advance, and then the color mixing ratio, that is, RGB values, of the panoramic image are adjusted based on the slide glass not carrying the sample so that the color mixing ratio of the panoramic image becomes white. That is, the standard of panoramic scan imaging is unified such that the background of the panoramic image is white.
Then, when the subsequent sphere imaging apparatus performs panoramic scan imaging, the slide bearing the sample at the time of scanning will remain white as a background because the effective image is shown instead of white, and the slide not bearing the sample at the time of scanning will remain white because the effective image is not shown. Based on this, the panoramic image obtained when the spherical imaging apparatus performs panoramic scanning imaging can be adjusted in image sharpness based on white.
In some optional implementation manners of the first embodiment of the present application, the step S101 further includes: and performing gamma curve correction processing on the sphere imaging equipment.
The inventors realized that when a light source is irradiated on a slide, the middle area of an image tends to be brighter than the edge area of the image when a ball imaging apparatus performs scan imaging, and based on this, in order to make the brightness contrast of the image smaller, the gamma parameter of the ball imaging apparatus may be adjusted, that is, the ball imaging apparatus is subjected to gamma curve correction processing so that the brightness contrast of the edge area of the image and the middle area of the image can be relatively reduced.
Further, in order to be able to unify the standards of panoramic scan imaging, gamma curve correction processing is also required for the spherical imaging apparatus. The gamma curve correction can be used for compensating the color display difference of images when the spherical camera devices in the slide scanners of different models scan and image, so that the images can show the same color display effect when the spherical camera devices in the slide scanners of different models scan and image.
By such an arrangement, after the gamma curve is corrected, the following purposes can be achieved: the color of the gray scale of the dark field is obviously improved, the color error of each gray scale is obviously reduced, the color detail of the dark field is clear, the image color is displayed consistently, the transparency is good, and the brightness contrast is relatively reduced.

In the embodiment of the application, the sphere camera device integrates n +1(n > ═ 2) optical lens groups which are uniformly embedded on the surface of the sphere device; all optical lens groups of the spherical camera device are ensured to share a shooting shutter control sensor, so that all the optical lens groups can shoot and collect optical signals at the same time; meanwhile, the manufacturing process of each group of optical lenses is uniform, so that the parameters such as refractive indexes of all the optical lenses are consistent, and the optical deviation rate of all the optical lenses is reduced to the minimum, so that the focus of each optical lens is concentrated at the spherical center of the spherical equipment.
In the embodiment of the application, the manufacturing process of each group of optical lenses is uniform, so that parameters such as refractive indexes of all the optical lenses are consistent, and the optical deviation ratios of all the optical lenses are reduced to the minimum, so as to ensure that the focal point of each optical lens is concentrated at the spherical center of the spherical equipment, namely the focal distance of the optical lens is approximately equal to the radius length of the spherical equipment.
In some optional implementation manners of the first embodiment of the present application, the step S101 further includes: adjusting a white balance parameter of the sphere photography apparatus.
In the embodiments of the present application, as research progresses, standardization of a panoramic image has become a necessary process for ensuring image sharpness. However, the inventors have realized that panoramic scan imaging is associated with many factors, such as the model of the slide scanner, which can cause color structure differences in the panoramic image.
In the embodiment of the present application, in order to unify the standard of panoramic scanning imaging, the white balance parameter may be adjusted for the spherical imaging apparatus. White balance is also understood as white balance, and here means that a slide glass not carrying a sample is placed under a sphere imaging device in advance, and then the color mixing ratio, that is, RGB values, of the panoramic image are adjusted based on the slide glass not carrying the sample so that the color mixing ratio of the panoramic image becomes white. That is, the standard of panoramic scan imaging is unified such that the background of the panoramic image is white.
Then, when the subsequent sphere imaging apparatus performs panoramic scan imaging, the slide bearing the sample at the time of scanning will remain white as a background because the effective image is shown instead of white, and the slide not bearing the sample at the time of scanning will remain white because the effective image is not shown. Based on this, the panoramic image obtained when the spherical imaging apparatus performs panoramic scanning imaging can be adjusted in image sharpness based on white.
In some optional implementation manners of the first embodiment of the present application, the step S101 further includes: and performing gamma curve correction processing on the sphere imaging equipment.
The inventors realized that when a light source is irradiated on a slide, the middle area of an image tends to be brighter than the edge area of the image when a ball imaging apparatus performs scan imaging, and based on this, in order to make the brightness contrast of the image smaller, the gamma parameter of the ball imaging apparatus may be adjusted, that is, the ball imaging apparatus is subjected to gamma curve correction processing so that the brightness contrast of the edge area of the image and the middle area of the image can be relatively reduced.
Further, in order to be able to unify the standards of panoramic scan imaging, gamma curve correction processing is also required for the spherical imaging apparatus. The gamma curve correction can be used for compensating the color display difference of images when the spherical camera devices in the slide scanners of different models scan and image, so that the images can show the same color display effect when the spherical camera devices in the slide scanners of different models scan and image.
By such an arrangement, after the gamma curve is corrected, the following purposes can be achieved: the color of the gray scale of the dark field is obviously improved, the color error of each gray scale is obviously reduced, the color detail of the dark field is clear, the image color is displayed consistently, the transparency is good, and the brightness contrast is relatively reduced.
