The intelligent host computer extracts the object features included in the first image and the second image, judges whether the matching degree of the object features and the preset indoor object features is larger than the preset matching degree, if so, executes step 505, and if not, executes step 506.

As an optional implementation manner, after determining that the matching degree of the object feature and the preset indoor object feature is less than or equal to the preset matching degree, the following steps may be further performed:

the intelligent host calculates the similarity between the spatial structure diagram included in the first image and the spatial structure diagram included in the second image; the spatial structure diagram comprises a plurality of diagrams for representing the spatial structure, for example, the spatial structure diagram may comprise a plurality of planes, any two plane intersection lines and any three plane intersection points;

the intelligent host judges whether the first category is matched with the second category;

if the two spatial structure diagrams are matched, the intelligent host computer calculates the similarity between the diagram characteristics of the spatial structure diagram corresponding to the first category and the diagram characteristics of the spatial structure diagram corresponding to the second category.

For example, when a first category of spatial structure representations included in the first image is a plane, an intersection line, an intersection point, and a second category of spatial structure representations included in the second image is a plane, the first category and the second category are considered to be unmatched; when the first category is a plane, an intersection line and an intersection point, and the second category is a plane, an intersection line and an intersection point, the first category is considered to be matched with the second category, at this time, similarity between the graphic features of the spatial structure graphic representation corresponding to the first category and the graphic features of the spatial structure graphic representation corresponding to the second category is further calculated, for example, whether a complete plane space schematic diagram can be formed between the position of the plane and the number of the planes in the first category and between the position of the plane and the number of the planes in the second category is calculated, wherein the higher the similarity is, the higher the probability that the complete plane space schematic diagram can be formed between the position of the plane and the number of the planes in the first category and the position of the plane and the number of the planes in the second category is represented is increased.

By implementing the optional implementation mode, before calculation, whether the categories of the space structure diagram are matched or not can be judged, if not, subsequent calculation is not needed, and the calculation amount is reduced.
