[0038] Example 1
[0039] figure 1 is a flow chart of a method for comparing the differences of street view images according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:
[0040] Step S1: acquiring multiple images shot for the preset street view area in different periods; wherein, each image corresponds to location information; the location information can be at least information such as street name, street number, longitude and latitude;
[0041] Step S2: determine any two images of the same position in different periods from the plurality of images according to the position information;
[0042] Step S3: Perform similarity calculation on the two images to determine an area where the similarity between the two images is less than a preset threshold.
[0043] This embodiment provides an efficient automatic detection method for finding differences in street view images captured in different periods, which not ...

[0064] Embodiment 2
[0065] Figure 12 is the comparison flow chart of the changing position of the street view image according to the embodiment of the present invention, such as Figure 12 shown, the process includes the following steps:
[0066] S1: Obtain image data I of the same street view area in two periods T1 / T2 from the street view image database, and position information P corresponding to each image, (T1={I1,P1}). This step is specifically implemented by the following methods: acquiring at the same time by a professional street view image acquisition vehicle, and each image corresponds to location information, longitude and latitude, and the like.
[0067] S2: According to the location information of the street view images, find two street view images of the same location in different periods.
[0068] This step is specifically realized by the following method: select a street view image I1 in T1, and obtain its position information P1. Search for the position...
