Background of the invention

Building products or elements include products used in constructing/remodeling buildings, including non-residential commercial buildings, governmental buildings, and residential or home (single family and multi-family) buildings.

An improvement project may include a replacement of existing building products (e.g., windows, doors, siding, roof, and gutters), an addition to an existing structure, a new structure, a renovation, etc.

Selection of materials and options offered in manufactured building products is critical in the delivery of an aesthetically pleasing and satisfying improvement or project and often determines or affects the cost of the products and the project. The building products industry represents a long standing industry directed to manufacturing, delivering, and installing architectural products or elements, e.g., windows, fenestration appurtenances, doors, hardware, etc.

Building product or element manufacturers face many challenges in providing their dealers/contractors with effective sales tools and support. A further problem faced by dealers and contractors is providing the home/business owner with a representative visual representation (“visualization”) of the final configured product or completed improvement project.

US20140314276 discloses a system and method for measuring distances related to a target object depicted in an image and the construction and delivery of supplemental window materials for fenestration. A digital image is obtained that contains a target object dimension and a reference object dimension in the same plane. The digital image may contain a target object dimension identified by an ancillary object and a reference object dimension in different planes. Fiducial patterns on the reference and optional ancillary objects are used that are recognized by an image analysis algorithm. Information regarding a target object and its immediate surroundings is provided to an automated or semi-automated measurement process, design and manufacturing system such that customized parts are provided to end users. The digital image contains a reference object having a reference dimension and calculating a constraint dimension from the digital image based on a reference dimension. The custom part is then designed and manufactured based on a calculated constraint dimension.

A system is needed that allows for easy retrieval of target dimensions (such as a window frame for a window opening in a wall), for visualization of presented product offerings for a specific target, and for firm quotes generated during the sales process.

Summary of the invention

A first aspect relates to a computer implemented method for determining the actual size of a target object within a digital image/video frame comprising the steps of:

i) obtaining a digital image/video frame containing a target object;

ii) obtaining data about the digital image/video frame containing a target object, the data comprising information about pixel resolution, and horizontal to vertical aspect ratio;

iii) identifying a target object within the digital image/video frame;

iv.a) determining boundaries of the target object from pixel data in the digital image/video frame;

iv. b) correlating and/or correcting the object boundaries with a figure shape from a database;

v. a) calculating/determining the pixel per arbitrary length unit or the arbitrary length unit per pixel of the actual target object in the horizontal and/or vertical direction of the digital image/video frame; and vi) calculating/determining, based on the correlated and/or corrected figure shape, the actual size of a target object from the number of pixel per arbitrary length unit or the arbitrary length unit per pixel of the actual target object in the horizontal and/or vertical direction of the digital image/video frame.

Another aspect relates to a data processing apparatus comprising means for carrying out the method of the present invention.

Yet another aspect relates to a computer program product comprising instructions which, when the program is executed by a computer, cause the computer to carry out the method of the present invention.

A second aspect relates to a computer implemented method for determining the actual size of a target object within a digital image/video frame comprising the steps of:

i) obtaining a digital image/video frame containing a target object;

iii) identifying a target object within the digital image/video frame;

iv.b) correlating and/or correcting the object boundaries with a figure shape from a database;

v) determining the pixel per arbitrary length unit or the arbitrary length unit per pixel of the actual target object in the horizontal and/or vertical direction of the digital image/video frame; wherein the determination is made from a precalibrated curve or look-up table based on a digital image/video frame recorded of a reference object with a known size, and wherein the same pixel resolution and horizontal to vertical aspect ratio is used as the digital image/video frame comprising the target object; and vi) calculating/determining, based on the correlated and/or corrected figure shape, the actual size of a target object from the number of pixel per arbitrary length unit or the arbitrary length unit per pixel of the actual target object in the horizontal and/or vertical direction of the digital image/video frame.

In one or more embodiments, step vi) is calculated/determined from a precalibrated curve or look-up table based on a digital image/video frame recorded of a reference object with a known size, and wherein the same pixel resolution and horizontal to vertical aspect ratio is used as the digital image/video frame comprising the target object.

A “target object” of the present invention refers to an object in the digital image/video frame having a constraint dimension that is measured by one or more methods of the present invention. In describing the present invention, “constraint dimension” refers to a measured portion or a multiple of a measured portion of a target object to which a designed part is to conform and a “constraint pixel dimension” refers to the length of a constraint dimension measured in pixels. A target object may contain a “symmetry element” which in the present invention refers to an aspect of the target object that in standard practice resides at a position within the target object such that the symmetry element divides a constraint dimension in an integer number of equal parts.

As will be appreciated by one skilled in the art, one or more aspects or embodiments of the present invention may be embodied as a system, method, computer program product or any combination thereof. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, the present invention may take the form of a computer program product embodied in any tangible medium of expression having computer usable program code embodied in the medium.

The invention or portions thereof may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc., that perform particular tasks or implement particular abstract data types. The invention may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.

Any combination of one or more computer usable or computer readable medium(s) may be utilized. The computer-usable or computer-readable medium may be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus or device. More specific examples (a non-exhaustive list) of the computer-readable medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CDROM), optical storage device or a magnetic storage device. Note that the computer-usable or computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via, for instance, optical scanning of the paper or other medium, then compiled, interpreted, or otherwise processed in a suitable manner, if necessary, and then stored in a computer memory. In the context of this document, a computer-usable or computer-readable medium may be any medium that can contain or store the program for use by or in connection with the instruction execution system, apparatus, or device.

Computer program code for carrying out operations of the present invention may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, Swift, C++,

C# or the like and conventional procedural programming languages, such as the C programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).

In one or more embodiments, image-processing algorithms are used to identify a target object within the digital image/video frame. Image processing algorithms are used to decipher certain attributes of the captured image frame. The processor uses image processing algorithms to identify one or more discernable objects in the image frame and attempts to identify them. For example, the image processing may use edge detection techniques to identify one or more objects in the captured image. For each detected object, identification algorithms are used to determine the likely identity of the object. Any number of techniques might be used for such a task. For example, the object might be normalized and compared to a database of possible objects using geometric and/or size analysis. If an object is viewed askew or at an angle, a normalization routine might rotate it and compensate for skew to result in a rectangular object. The features of the image object can then be compared to the database of known rectangular objects having similar dimensional relationships, (e.g. ratio of length to width, such as other currency) and the denomination can be determined. Other techniques, such as morphological filters, look-up table, trained artificial neural network, some threshold, or an object repository of learned objects may be used as well.

The content of the image frame may in some embodiments be deciphered by processing the frame for edge pattern detection. The processed edge pattern is classified by artificial neural networks that have been trained on a list of known objects, in a look up table, or by a threshold. Once the pattern is classified, a descriptive sentence is constructed consisting of the object and its certain attributes.

In other embodiments, a graphical user interface for interactively selecting a target object is used to identify a target object within the digital image/video frame.

The computer comprises a processor and a memory coupled to the processor. The memory is coupled to the processor, and the memory comprises program instructions implementing a graphical user interface for interactively selecting a target object. Program instructions are executable by the processor for:

The CPU is coupled through the CPU local bus to a host/PCI/cache bridge or chipset. A second level (i.e. L2) cache memory may be coupled to a cache controller in the chipset. For some processors, the external cache may comprise an L1 or first level cache. The bridge or chipset couples to main memory via a memory bus. The main memory comprises dynamic random access memory (DRAM) or extended data out (EDO) memory, or other types of memory such as ROM, static RAM, flash, and non-volatile static random access memory (NVSRAM), bubble memory, etc.

The software adapted to implement the system and methods of the present invention may also reside, in whole or in part, in the static or dynamic main memories or in firmware within the processor of the computer system (i.e. within microcontroller, microprocessor or microcomputer internal memory).

It is noted that computer programs implementing the system and methods of this invention will commonly be distributed to users via Internet download or on a distribution medium such as floppy disk, CDROM, DVD, flash memory, portable hard disk drive, etc. From there, they will often be copied to a hard disk or a similar intermediate storage medium. When the programs are to be run, they will be loaded either from their distribution medium or their intermediate storage medium into the execution memory of the computer, configuring the computer to act in accordance with the method of this invention. All these operations are well known to those skilled in the art of computer systems.

The computer implemented method comprises the step of iv.b) correlating and/or correcting the object boundaries with a figure shape from a database; and wherein step vi) is based on the correlated and/or corrected figure shape. This is to refine the calculation by removing possible pixel errors or indirectly removing objects covering parts of the target object.

In one or more embodiments, the computer implemented method further comprises the steps of v.b) adjusting the size of the target object in the digital image/video frame to contain as many pixels as possible within the pixel resolution limits of the original digital image/video frame, while retaining its original horizontal to vertical aspect ratio; and v.c) adjusting the in step v.a) calculated/determined pixel per arbitrary length unit or arbitrary length unit per pixel of the actual target object in the horizontal and/or vertical direction of the digital image/video frame to the resized target object. This adjustment makes it easier to calculate/determine the actual size of the target object.

In one or more embodiments, step v.a) is calculated/determined by using machine learning algorithms.

A third aspect relates to an apparatus for determining the actual size of a target object within a digital image/video frame comprising:

v.a) calculating/determining the pixel per arbitrary length unit or the arbitrary length unit per pixel of the actual target object in the horizontal and/or vertical direction of the digital image/video frame; and vi) calculating/determining, based on the correlated and/or corrected figure shape, the actual size of a target object from the number of pixel per arbitrary length unit or the arbitrary length unit per pixel of the actual target object in the horizontal and/or vertical direction of the digital image/video frame.

It should be noted that embodiments and features described in the context of one of the aspects of the present invention also apply to the other aspects of the invention.

Brief description of the figures

Figure 1 shows a digital image containing a target object that has already been identified, and its boundaries determined;

Figure 2 shows that the minimum distance (Lmin) from which a target object can be photographed depends on its size;

Figure 3 shows exemplary part of a look-up table; and

Figure 4 shows the target object in Figure 1, adjusted to contain as many pixels as possible within the pixel resolution limits of the original digital image/video frame.

Detailed description of the invention

Figure 1 shows a digital image containing a target object that has already been identified, and its boundaries determined.

As shown in Figure 2, the minimum distance (Lmin) from which a target object can be photographed depends on its size. At the same time, the number of pixels used to define the objects is the same. This observation is crucial for the present invention, as different sizes of objects will be defined by a different number of pixels per object arbitrary length unit (e.g. per mm) of the actual object. Hence, fewer pixels are available per area object for showing details in a larger object than in a smaller object. The lack or presence of details may be used to determine the number of pixels per object arbitrary length unit (e.g. per mm) of the actual object by using machine learning methods.

When calculated/determined, the number of pixels per object arbitrary length unit (e.g. per mm) of the actual object is used to calculate/determine the actual size of the target object. The calculation/determination is made from a pre-calibrated curve or look-up table based on a digital image/video frame recorded of a reference object with a known size, and wherein the same pixel resolution and horizontal to vertical aspect ratio is used as the digital image/video frame comprising the target object. An exemplary part of a look-up table is shown in Figure 3. In a preferred embodiment, the size of the target object is adjusted to contain as many pixels as possible within the pixel resolution limits of the original digital image/video frame (Figure 4), while retaining its original horizontal to vertical aspect ratio. The calculated/determined number of pixels per object arbitrary length unit (e.g. per mm) of the actual object will be corrected accordingly. This adjustment makes it easier to calculate/determine the actual size of the target object.
