Patent Application
20150154665
This disclosure relates generally to a Plan Reader.
Architects and engineers designing buildings or infrastructures such as electrical; heating, ventilation, and air conditioning (HVAC), or plumbing systems, often generate plans or blueprints showing the components required. When these plans are sent to contractors to obtain price bids, it is often necessary to review the plans and count each of the components to produce a bill of materials for the job to produce a quote. In some cases, a similar process may be used by a supplier asked to provide pricing.
The following presents a simplified summary of the disclosure to provide a basic understanding to the reader. This summary is not an extensive overview of the disclosure, nor does it identify key or critical elements of the claimed subject matter, or define its scope. Its sole purpose is to present some concepts disclosed in a simplified form as a precursor to the more detailed description that is later presented.
The instant application discloses, among other things, techniques to provide for Plan Reader. In one embodiment, a plan or blueprint for a project may be scanned, with software analyzing the resulting digital image to identify symbols representing various components or component types used. These symbols may be matched with known symbols from previous projects, from a legend on the plan, or manually. In one embodiment, a specification may identify particular requirements or part numbers desired for the project. A bill of materials (BOM) may be produced. In one embodiment, Plan Reader may integrate with a supplier's or manufacturer's catalog to identify components meeting specifications, and provide a price estimate. Plan Reader may be implemented on a distributed system or on a single computer.
Many of the attendant features may be more readily appreciated as they become better understood by reference to the following detailed description considered in connection with the attached drawings.

The present description may be better understood from the following detailed description read in light of the appended drawings, wherein:
Like reference numerals are used to designate like parts in the accompanying drawings.
A more particular description of certain embodiments of Plan Reader may be had by references to the embodiments shown in the drawings that form a part of this specification, in which like numerals represent like objects.
Scanner 120 may be a flatbed scanner, a digital camera, an all-in-one device, or any other device capable of capturing a digital image of a hard copy of a plan. A plan may be a plan for an electronic device, a blueprint for a construction job, or any other sort of graphical description of a project including components symbolized by marks on the plan.
User Device 110 may be used process a plan using a scan produced by Scanner 120. Software on User Device 110 may use pattern recognition or other techniques to identify components drawn on the plan by comparing the scanned image to known images, or by performing a mathematical analysis of the scan. Known images may be obtained from previous scans, from manufacturer or supplier catalogs, from images available from the Internet, or from other sources.
Network 140 may include Wi-Fi, cellular data access methods, such as 3G or 4GLTE, Bluetooth, NFC, the internet, local area networks, wide area networks, or any combination of these or other means of providing data transfer capabilities. In one embodiment, Network 140 may comprise Ethernet connectivity. In another embodiment, Network 140 may comprise fiber optic connections.
Server 130 may include one or more computers, and may serve a number of roles. Servers 130 may be conventionally constructed, or may be of a special purpose design for processing data for Plan Reader. One skilled in the art will recognize that Server 130 may be of many different designs and may have different capabilities.
Server 130 may host applications, data, or other information supporting Plan Reader. In one embodiment, for example, Server 130 may host a web site enabling a Plan Reader user to load a scanned image of a plan, and Server 130 may provide an analysis.
User Device 110 may be used to access information or programs on Server 130 related to Plan Reader. Such information or programs may include, for example, processing scanned images to create a bill of materials, provide a course of patterns for component recognition, and storage of scanned plans.
Plan Reader may recognize, using pattern recognition similar to optical character recognition, for example, the rectangles with lettering contained such as MP4-1 and MP4-2 as being electrical panels, and may provide a count of such devices on the overall plan. Plan Reader may be used to provide a BOM for buildings, electronic devices, automobiles, or any type of object for which there are plans containing distinctive marks for various types of components.
Plan Reader may use previously loaded information or mathematical analysis to identify components. For example, patterns may be stored in the program, in a database of component patterns, as mathematical formulae, or in other structures. In another embodiment, patterns may be read from a plan containing a legend of components used. In yet another embodiment, Plan Reader may recognize various components based on similar symbols, which may be manually matched to components after initial processing, so, for example, a list of patterns may be displayed to a user for identification. One having skill in the art will recognize that many different approaches may be used to providing pattern recognition abilities.
One having skill in the art will recognize that many different components, including electrical, plumbing, HVAC, structural, and other sub-assemblies or parts required to construct buildings, devices, or other objects, may be scanned and recognized.
In its most basic configuration, Computing Device 1300 typically includes at least one Central Processing Unit (CPU) 1302 and Memory 1304. Depending on the exact configuration and type of Computing Device 1300, Memory 1304 may be volatile (such as RAM), non-volatile (such as ROM, flash memory, etc.) or some combination of the two. Additionally, Computing Device 1300 may also have additional features/functionality. For example, Computing Device 1300 may include multiple CPUs. The described methods may be executed in any manner by any processing unit in computing device 1300. For example, the described process may be executed by both multiple CPUs in parallel.
