Abstract

Methods and systems generate and project an actual sized image of an object. An object or a representation of an object may be pre-processed. The pre-processing of a representation of the object may include determining pixels that belong to the object and pixels that belong to a background of the image. The pre-processing may include calculating a bounding box for the object. The projection may include determining an area of projection suitable for the bounding box of the object. The projection may further include projecting an image of intermediate dimensions. The projection may further include up-sampling or down-sampling the image to an actual size. The projection of the actual sized image may be made interactive by rendering at least one additional view of the object.

Claims

1. A computer-implemented method to display an actual sized image of an object, the method comprising using at least one processor to:

receive a photographic representation of the object and at least one dimensional measurement of the object;

determine and store a bounding box for the object, the bounding box having dimensions along length (X), height (Y), and depth (Z) axes and represented as E_Max[X, Y, Z], at least one of the dimensions corresponding to the at least one dimensional measurement, the bounding box based on pixels in the photographic representation that belong to the photographic representation;

receive a size of a display, the size represented by pixels per inch of the display (“

DPI_S”

);

calculate an actual height of the object as E_Max[Y]*DPI_S pixels based on the bounding box;

calculate an actual width of the object as E_Max[X]*DPI_S pixels based on the bounding box;

scale an image of the object to an actual size based on the calculated actual height and actual width;

up-sample or down-sample the scaled image to a projected size of E_Max[X]*DPI_S, E_Max[Y]*DPI_S; and

project a projection of the actual sized image of the object for display.

2. The method of claim 1, wherein the bounding box is represented as a range between a set of minimum coordinates and a set of maximum coordinates such that each point on the object is within the range, wherein each coordinate is a representation of a dimension.

3. The method of claim 1, further comprising using the processor to perform at least one of:

(i) indicate that the actual sized image of the object is actual-sized, and (ii) display the calculated actual height and actual width of the object.

4. The method of claim 3, further comprising using the processor to:

responsive to a request for conversion between a first unit of measurement to a second unit of measurement, display the calculated actual height and actual width of the object in the second unit of measurement.

5. The method of claim 1, wherein the projection includes an orthographic projection.

6. The method of claim 1, further comprising using the processor to generate an image of intermediate dimensions prior to scaling the image, wherein the image of intermediate dimensions preserves an aspect ratio of the object.

7. The method of claim 1, further comprising using the processor to render a view of the actual sized image responsive to a request for at least one of a viewing direction and an orientation.

8. The method of claim 1, further comprising:

calculating a scaling factor based on the at least one measurement, wherein the scaling factor is calculated based on a known size of a second object positioned relative to the object in the photographic representation.

9. The method of claim 8, wherein the scaling factor is calculated based on a sizing chart by calculating a length in pixels of the object and a corresponding actual length of the object.

10. A system for displaying an actual sized image of an object, the system comprising:

a storage device; and

at least one processor configured to;

receive a photographic representation of the object and at least one dimensional measurement of the object;

determine and store a bounding box for the object, the bounding box having dimensions along length (X), height (Y), and depth (Z) axes and represented as E_Max[X, Y, Z], at least one of the dimensions corresponding to the at least one dimensional measurement, the bounding box based on pixels in the photographic representation that belong to the photographic representation;

receive a size of a display, the size represented by pixels per inch of the display (“

DPI_S”

);

calculate an actual height of the object as E_Max[Y]*DPI_S pixels based on the bounding box;

calculate an actual width of the object as E_Max[X]*DPI_S pixels based on the bounding box;

scale an image of the object to an actual size based on the calculated actual height and actual width;

up-sample or down-sample the scaled image to a projected size of E_Max[X]*DPI_S, E_Max[Y]*DPI_S; and

provide a projection of the actual sized image of the object for display.

11. The system of claim 10, wherein the bounding box is represented as a range between a set of minimum coordinates and a set of maximum coordinates such that each point on the object is within the range, wherein each coordinate is a representation of a dimension.

12. The system of claim 10, wherein the processor is further configured to generate an image of intermediate dimensions prior to scaling the image, the image of intermediate dimensions preserving an aspect ratio of the object.

13. The system of claim 10, further comprising:

calculating a scaling factor based on the at least one measurement.

14. At least one non-transitory computer-readable media storing program instructions that, when executed, cause at least one processor to perform operations to display an actual sized image of an object, the operations comprising:

receiving a photographic representation of the object and at least one dimensional measurement of the object;

determining and storing a bounding box for the object, the bounding box having dimensions along length (X), height (Y), and depth (Z) axes and represented as E_Max[X, Y, Z], at least one of the dimensions corresponding to the at least one dimensional measurement, the bounding box based on pixels in the photographic representation that belong to the photographic representation;
