Abstract
The invention relates to a position aggregation-based three-dimensional panoramic picture sparsification method. According to the method of the invention, analysis is made based on a current traditional three-dimensional panoramic picture sparsification method, and a new idea is provided for picture sparsification, and therefore, the efficiency of picture sparsification can be greatly improved. Spatial analysis is performed on three-dimensional panoramic pictures, and a large quantity of data are reduced, and therefore, the number of the pictures can be greatly reduced, and processing ability can be improved.
Description
Technical field
What the present invention relates to is the vacuate technical method of panoramic map picture, namely how carries out the few intelligence reduction of quantity for the panoramic map picture of magnanimity.
Background technology
In three-dimensional panorama map datum process field, the vacuate of panoramic pictures is one of core technology, because panoramic map picture magnanimity often, if do not add the process one by one of differentiation, its workload is surprising, therefore in order to meet the high requirement of map renewal frequency, must carry out vacuate to picture.Current vacuate method mainly processes according to the mathematical method of digital difference, and the shortcoming of the method often the picture vacuate of primary location is fallen, and cause map to lack, what need the later stage supplies process, complex steps.
Summary of the invention
The present invention is directed to current technology Problems existing, propose the new method of the three-dimensional panorama picture vacuate of position-based polymerization, the method mainly carries out spatialization analysis to three-dimensional panorama picture, then the data of magnanimity are reduced, so just greatly reduce picture number, improve processing power.
Because each in panoramic map picture is all be associated with actual locus, the method that therefore can be distributed by analysis position analyzes the paradigmatic relation of picture indirectly.According to the geographical position coordinates of every pictures, analyze the positional distance not having adjacent two pictures, then a threshold value is set, when distance is less than this threshold value, it is a picture by multiple picture indicia, in this way polymerization analysis is carried out to all pictures, finally get the picture that the picture that completes of polymerization vacuate splices as actual map.
Embodiment
In order to make objects and advantages of the present invention clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In order to realize method of the present invention, carry out according to following steps:
1, the coordinate of every pictures is recorded;
2, a polymerization threshold value is set;
3, the distance often between adjacent two pictures is calculated;
4, will compare apart from threshold value, be less than uniting two into one of threshold value;
5, the last picture retained is got as the later result of vacuate.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (2)
1. a three-dimensional panorama picture vacuate method for position-based polymerization, mainly carries out spatialization analysis to three-dimensional panorama picture, then reduces the data of magnanimity, so just greatly reduce picture number, improve processing power.
2. the three-dimensional panorama picture vacuate method of position-based polymerization according to claim 1, is characterized in that carry out polymerization analysis to mass picture, vacuate becomes the picture of negligible amounts using picture geographic location as consideration target.
