Abstract

Methods, systems, and computer readable media are disclosed for determining a pixel-to-length ratio between a number of pixels disposed over a predetermined length of a reference object within an image of a siding sample and the predetermined length of the reference object. A first and second distance between respective first and second pairs of points within the image corresponding to respective first and second length measurements of the siding sample are determined, as well as a first and second number of pixels disposed between the first and second pair of points, respectively. Furthermore, the method, system, and computer readable medium disclose determining the first length measurement based on the pixel-to-length ratio and the first number of pixels, determining the second length measurement based on the pixel-to-length ratio and the second number of pixels, and identifying a siding product associated with the first and second length measurements.

Claims

1. A mobile device, comprising:

an image capture device configured to capture an image of a siding sample including a reference object; and

a central processing unit (CPU) configured to;

adjust an orientation of the reference object within the image of the siding sample to align edges of the reference object with edges of the siding sample;

determine a ratio between a first number of pixels spanned by a dimension of the reference object within the image of the siding sample and a measurement of the dimension of the reference object;

determine a first measurement of a first dimension of the siding sample based upon the ratio and a second number of pixels spanned by the first dimension of the siding sample within the image of the siding sample; and

identify a siding product associated with the first measurement.

2. The mobile device of claim 1, wherein the CPU is further configured to identify the siding product associated with the first measurement by communicating with a computing device.

3. The mobile device of claim 1, wherein the CPU is further configured to adjust the orientation of the reference object only when the CPU determines that the orientation needs to be adjusted.

4. The mobile device of claim 1, wherein the CPU is further configured to rectify the image of the siding sample so the perspective of the siding sample faces forward if the reference object includes perspective distortion.

5. The mobile device of claim 1, wherein the CPU is further configured to adjust the orientation of the reference object such that respective horizontal and vertical edges of each of the reference object and the siding sample are aligned with edges corresponding to a horizontal-vertical plane.

6. The mobile device of claim 1, wherein the CPU is further configured to determine a second measurement of a second dimension of the siding sample based upon the ratio and a third number of pixels spanned by the second dimension of the siding sample within the image of the siding sample and to identify the siding product based upon the first and second measurements.

7. The mobile device of claim 6, wherein:

the first measurement corresponds to a face dimension of the siding sample,

the second measurement corresponds to a profile dimension of the siding sample, and

the CPU is further configured to identify the siding product by identifying a siding product stored in a siding product reference database having a face dimension and a profile dimension matching the first measurement and the second measurement, respectively.

8. The mobile device of claim 1, wherein the CPU is further configured to detect the reference object using at least one of:

a Scale-Invariant Feature Transform (SIFT);

a Speeded Up Robust Features (SURF);

a Radon transform;

or

a Hough transform.

9. A computer-implemented method for identifying a siding product, comprising:

adjusting, by one or more processors, an orientation of a reference object within a captured image of a siding sample to align edges of the reference object with edges of the siding sample;

determining, by one or more processors, a ratio between a first number of pixels spanned by a dimension of the reference object within the image of the siding sample and a measurement of the dimension of the reference object;

determining, by one or more processors, a first measurement of a first dimension of the siding sample based upon the ratio and a second number of pixels spanned by the first dimension of the siding sample within the image of the siding sample; and

identifying, by one or more processors, a siding product associated with the first measurement.

10. The method of claim 9, wherein the act of adjusting comprises:

determining, by one or more processors, whether the orientation of the reference object needs to be adjusted, and

wherein the act of adjusting the orientation of the reference object comprises;

adjusting the orientation of the reference object only when the one or more processors determine that the orientation needs to be adjusted.

11. The method of claim 9, further comprising:

rectifying, by one or more processors, the image of the siding sample so the perspective of the siding sample faces forward if the reference object includes perspective distortion.

12. The method of claim 9, wherein the act of adjusting the orientation of the reference object comprises:

adjusting the orientation of the reference object such that respective horizontal and vertical edges of each of the reference object and the siding sample are aligned with edges corresponding to a horizontal-vertical plane.

13. The method of claim 9, further comprising:

determining, by one or more processors, a second measurement of a second dimension of the siding sample based upon the ratio and a third number of pixels spanned by the second dimension of the siding sample within the image of the siding sample, and

wherein the act of identifying the siding sample further comprises;

identifying the siding product based upon the first and second measurements.

14. The method of claim 13, wherein:

the first measurement corresponds to a face dimension of the siding sample,

the second measurement corresponds to a profile dimension of the siding sample, and
