According to embodiments of the invention, the number of plies of compressed in layers what with the compression after every tomographic image data comprise how much being inversely proportional to of image detail information.That is to say that the compressed in layers of more multi-layered number can make image detail information be segmented more.The number of plies of compressed in layers is more many, and the image detail information that every tomographic image data comprise is more few; And the number of plies of compressed in layers is more few, and the image detail information that every tomographic image data comprise is more many.Still with reference to Fig. 2 A, Fig. 2 B, Fig. 2 C, the number of plies that wherein shows compressed in layers is 3 situation, and the situation of the image detail information that the ground floor view data comprises has been shown among Fig. 2 A.If the number of plies of compressed in layers is reduced to 2, then to be that 3 situation is compared more for the image detail information that comprises of every tomographic image data and the number of plies, are that the image detail information that the ground floor view data comprises under 2 the situation will be more than the image detail information in the image shown in Fig. 2 A in the number of plies namely.
In above-mentioned steps S103, alternatively, image can be divided into a plurality of zones, and compressed in layers is carried out in described a plurality of zones respectively, thereby obtain to comprise the multi-layer image data of the image detail information of different levels for each zone.For example, image averaging shown in Fig. 2 A, Fig. 2 B, Fig. 2 C can be divided into upper left, lower-left, upper right, four zones, bottom right, and respectively compressed in layers is carried out in these four zones, thereby comprise the multi-layer image data of the image detail information of different levels for each the zone acquisition in these four zones.
Next, execution in step S105 wherein, with the predefined time interval, according to image detail information order from less to more, successively transmits described multi-layer image data to remote equipment, to be used for demonstration.Alternatively, image is being divided into a plurality of zones and is carrying out under the situation of compressed in layers respectively to described a plurality of zones, can be with the predefined time interval, according to image detail information order from less to more, for each zone, successively transmit described multi-layer image data to remote equipment, to be used for demonstration.Wherein, the described predefined time interval can be selected according to actual needs, and this time interval is more few, show that at the remote equipment epigraph ground is more fast, but the network bandwidth that takies is just more big; And should the time interval more big, show that at the remote equipment epigraph ground is more slow, and the network bandwidth that takies is more little.
According to embodiments of the invention, in step S105, can be every to remote equipment transmission one deck view data, just show these tomographic image data at remote equipment, thereby on remote equipment, show image in progressive mode.Shown in Fig. 2 A, Fig. 2 B, Fig. 2 C, divide transmission three tomographic image data three times, every transmission one deck view data, just show these tomographic image data at remote equipment, thereby image just can show in progressive mode, the user of remote equipment just can view the roughly situation of image before view data is transmitted fully, and along with transmission and the demonstration of every tomographic image data, the image detail that the user of remote equipment can view is just more many.
Fig. 3 schematically illustrates the flow chart of remote image display packing 150 according to an embodiment of the invention.Method 150 is similar with said method 100, and each technological means and the technical characterictic of above-described method 100 also are applicable to method 150.Especially, in method 150, the one or more zones in the image change, and namely may be that the subregion in the image changes, and other zone do not change, and also can be that the Zone Full in the image all changes.
As shown in Figure 3, method 150 starts from step S151, wherein, according to and remote equipment between transmission conditions and image in the size of data in one or more zones of changing, determine whether the view data in described one or more zones is carried out compressed in layers, and the number of plies of definite compressed in layers.S101 is similar with above-mentioned steps, alternatively, when transmission conditions relatively poor (for example, network speed is slow, the available network bandwidth is few), when the size of the view data that one or more that changes is regional is big, can determine the view data in described one or more zones is carried out compressed in layers; And more poor when transmission conditions, when the view data size in the one or more zones that change was more big, the number of plies of compressed in layers was then more many.Alternatively, can calculate the transmission time according to view data size and the transmission conditions in the one or more zones that change, under the situation of transmission time greater than predefined time threshold, with regard to determining view data is carried out compressed in layers, and calculate the number of plies of compressed in layers based on this transmission time.Similarly, above-mentioned predefined time threshold can be chosen according to actual needs, to the higher occasion of remote image display requirement in the remote operation, this predefined time threshold can be set at less value.
After step S151, execution in step S153 wherein, carries out compressed in layers according to the described number of plies to the view data in described one or more zones, to comprise the multi-layer image data of the image detail information of different levels for described one or more zones acquisition.Similarly, the number of plies of compressed in layers what with the compression after every tomographic image data comprise how much being inversely proportional to of image detail information.That is to say that the compressed in layers of more multi-layered number can make image detail information be segmented more.The number of plies of compressed in layers is more many, and the image detail information that every tomographic image data comprise is more few; And the number of plies of compressed in layers is more few, and the image detail information that every tomographic image data comprise is more many.
Next, execution in step S155 wherein, with the predefined time interval, according to image detail information order from less to more, for described one or more zones, successively transmits described multi-layer image data to remote equipment, to be used for demonstration.S105 is similar with above-mentioned steps, and the described predefined time interval can be selected according to actual needs, and this time interval is more few, show that at the remote equipment epigraph ground is more fast, but the network bandwidth that takies is just more big; And should the time interval more big, show that at the remote equipment epigraph ground is more slow, and the network bandwidth that takies is more little.According to embodiments of the invention, in step S155, can be every to remote equipment transmission one deck view data, just show these tomographic image data at remote equipment, thereby on remote equipment, show image in progressive mode.Shown in Fig. 2 A, Fig. 2 B, Fig. 2 C, divide transmission three tomographic image data three times, every transmission one deck view data, just show these tomographic image data at remote equipment, thereby image just can show in progressive mode, the user of remote equipment just can view the roughly situation of image before view data is transmitted fully, and along with transmission and the demonstration of every tomographic image data, the image detail that the user of remote equipment can view is just more many.
According to embodiments of the invention, suppose to have in the image two zones of first area and second area to change, and first area and second area successively change, during successively to remote equipment transmission multi-layer image data, may there be following several situation for first area and second area:

(5) if there is not common factor between first area and the second area, then calculate the 3rd zone that comprises first area and second area, in the 3rd zone, under the shared situation of ratio more than or equal to predefined the 3rd threshold value, transmit the multi-layer image data in the 3rd zone to remote equipment at first area and second area.
(6) if there is not common factor between first area and the second area, then calculate the 3rd zone that comprises first area and second area, at first area and second area in the 3rd zone under the shared situation of ratio less than predefined the 3rd threshold value, to the multi-layer image data of remote equipment transmission first area and second area.
In above-mentioned situation (5) and situation (6), described predefined the 3rd threshold value can determine according to actual needs that the 3rd threshold value is more little, and the speed of reception and demonstration image is just more fast on the remote equipment, but the network data quantity transmitted is just more big; And the 3rd threshold value is more big, and the speed of reception and demonstration image is just more slow on the remote equipment, but the network data quantity transmitted is just more little.
