Methods, apparatus, and articles of manufacture to measure geographical features using an image of a geographical location
View Patent ↗Methods, apparatus, and articles of manufacture to measure geographical features using an image of a geographical location are disclosed. An example method includes identifying first features of a first open market from a first image of a first geographic area, identifying second features of a second image of a second geographic area, comparing the first features to the second features, and identifying a second open market in the second image based on the comparison.
1. A method, comprising:
identifying, by executing an instruction with a processor, first features of a first open market from a first image of a first geographic area;
identifying, by executing an instruction with the processor, second features of a second image of a second geographic area;
comparing the first features to the second features by executing an instruction with the processor;
identifying, by executing an instruction with the processor, additional open markets in the second image based on the comparison;
determining, by executing an instruction with the processor, first characteristics of the additional open markets based on the comparison of the first features to the second features and corresponding second characteristics of the first open market, the first characteristics including at least one of a) numbers of stores in the additional open markets, b) physical sizes of the additional open markets, c) whether the additional open markets are in previously enumerated areas or previously unenumerated areas, or d) trade areas of the additional open markets;
modifying, by executing an instruction with the processor, a sampling area in the second geographic area to be physically sampled to include in the sampling area at least a subset of the additional open markets in the second geographic area based on the first characteristics; and
providing the modified sampling area to a sampler for physical sampling of the second geographic area according to the modified sampling area to determine a number of stores in the second geographic area, the physical sampling including determining a retail characteristic of the modified sampling area.
2. The method of claim 1 , further including training a feature locator using the first features and the first image.
3. The method of claim 1 , wherein identifying the first features includes using a scale-invariant feature transform, a Bag of Words for Computer Vision model, or interest point descriptors.
4. The method of claim 1 , further including identifying a trade area for a first one of the additional open markets, identifying the trade area including determining the trade area to have at least a threshold number of customers of the first one of the additional open markets.
5. The method of claim 1 , further including predicting a first number of stores in a first one of the additional open markets based on an area of at least a portion of the second image.
6. The method of claim 1 , further including ranking the additional open markets relative to a third open market in a third image.
7. The method of claim 1 , wherein the first and second images include aerial images.
8. A method of claim 1 , further including estimating a growth rate of a first one of the additional open markets based on the first features.
9. An apparatus, comprising:
an image divider to define a first image of a first geographic area and a second image of a second geographic area;
a feature locator to identify first features of a first open market from the first image and to identify second features of a portion of the second image;
a zone analyzer to:
compare the first features to the second features and identify additional open markets in the portion of the second image based on the comparison; and
determine first characteristics of the additional open markets based on the comparison of the first features to the second features and corresponding second characteristics of the first open market, the first characteristics including at least one of a) numbers of stores in the additional open markets, b) physical sizes of the additional open markets, c) whether the additional open markets are in previously enumerated areas or previously unenumerated areas, or d) trade areas of the additional open markets; and
a sample stratifier to:
modify a sampling area in the second geographic area to be physically sampled to include in the sampling area at least a subset of the additional open markets in the second geographic area based on the first characteristics; and
provide the modified sampling area to a sampler for physical sampling of the second geographic area according to the modified sampling area to determine a number of stores in the second geographic area, the physical sampling including determining a retail characteristic of the modified sampling area.
10. The apparatus of claim 9 , further including a retail trade area identifier to identify a retail trade area of a first one of the additional open markets, the retail trade area including at least a threshold amount of customers of the -a first one of the additional open markets.
11. The apparatus of claim 9 , wherein the feature locator includes a scale invariant feature transform locator to identify the first features using a scale invariant feature transform.
12. The apparatus of claim 9 , wherein the zone analyzer is to rank the first open market relative to the additional open markets.
13. The apparatus of claim 9 , wherein the zone analyzer is to estimate the numbers of stores in the additional open markets of stores in the additional open markets.
14. The apparatus of claim 9 , wherein the zone analyzer is to estimate a total number of open markets in the second geographic area.
15. A tangible computer readable medium comprising computer readable instructions which, when executed, cause a processor to at least:
identify first features of a first open market from a first image of a first geographic area;
identify second features of a second image of a second geographic area;
compare the first features to the second features;
identify additional open markets in the second image based on the comparisons;
determine first characteristics of the additional open markets based on the comparison of the first features to the second features and corresponding second characteristics of the first open market, the first characteristics including at least one of a) numbers of stores in the additional open markets, b) physical sizes of the additional open markets, c) whether the additional open markets are in previously enumerated areas or previously unenumerated areas, or d) trade areas of the additional open markets;
modify a sampling area in the second geographic area to be physically sampled to include in the sampling area at least a subset of the additional open markets in the second geographic area based on the first characteristics; and
provide the modified sampling area to a sampler for physical sampling of the second geographic area according to the modified sampling area to determine a number of stores in the second geographic area, the physical sampling including determining a retail characteristic of the modified sampling area.
16. The tangible computer readable medium of claim 15 , wherein the instructions are further to cause the processor to train a feature locator using the first features and the first image.
17. The tangible computer readable medium of claim 15 , wherein the instructions are to cause the processor to identify the first features using a scale-invariant feature transform, a Bag of Words for Computer Vision model, or interest point descriptors.
18. The tangible computer readable medium of claim 15 , wherein the instructions are further to cause the processor to identify the trade areas of the additional open markets based on physical distances between the first and additional open markets.
19. The tangible computer readable medium of claim 15 , wherein the instructions are further to cause the processor to estimate a total number of open markets in the second geographic area based on located open markets in the second geographic area, the located open markets including the additional open markets.
