PRESENTATION OF DATA; RECORD CARRIERS; HANDLING RECORD CARRIERS - G06T: IMAGE DATA PROCESSING OR GENERATION, IN GENERAL ## Abstract An item measuring system and its relate processes may perform operations that include receiving an image of an item and a reference tag; identifying a perimeter of the item; identifying a type of the reference tag; identifying known dimensions of the reference tag based on the type; determining dimensions of the item in standardized units based on the known dimensions of the reference tag; and outputting information identifying the dimensions of the item. ## Claims ### Claim 1 A computer-implemented method performed by an item measuring system comprising: receiving an image of an item and a reference tag; identifying a perimeter of the item; identifying a type of the reference tag; identifying known dimensions of the reference tag based on the type; determining dimensions of the item in standardized units based on the known dimensions of the reference tag; and outputting information identifying the dimensions of the item. ### Claim 2 (depends on 1) The method of claim 1, wherein the determining the dimensions of the item further comprises: determining a length represented by each pixel in the image based on the known dimensions of the reference tag; determining the dimensions of item in the form of pixels in the image; and converting the dimensions of the item in the form of pixels to the standardized units based on the length represented by each pixel. ### Claim 3 (depends on 1) The method of claim 1, wherein the identifying the type of the reference tag comprises extracting features of the reference tag. ### Claim 4 (depends on 3) The method of claim 3, wherein the features include at least one of: a barcode; a Quick Response (QR) code; an address; a postage stamp; an indicia; a logo; and a format or layout of content included on the reference tag; ### Claim 5 (depends on 1) The method of claim 1, wherein the image is received from a user device hosting an application for measuring the item based on capturing the image of the item. ### Claim 6 (depends on 1) The method of claim 1, wherein the reference tag is affixed to the item. ### Claim 7 (depends on 6) The method of claim 6, wherein the reference tag includes at least one of: a shipping label; a standalone label; and a three-dimensional object. ### Claim 8 (depends on 1) The method of claim 1, wherein the image includes an isometric view of the item. ### Claim 9 A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computing device to cause the computing device to perform operations comprising: receiving an image of an item and a reference tag; identifying a perimeter of the item; identifying a type of the reference tag; identifying known dimensions of the reference tag based on the type; determining dimensions of the item in standardized units based on the known dimensions of the reference tag; and outputting information identifying the dimensions of the item. ### Claim 10 (depends on 9) The computer program product of claim 9, wherein the determining the dimensions of the item further comprises: determining a length represented by each pixel in the image based on the known dimensions of the reference tag; determining the dimensions of item in the form of pixels in the image; and converting the dimensions of the item in the form of pixels to the standardized units based on the length represented by each pixel. ### Claim 11 (depends on 9) The computer program product of claim 9, wherein the identifying the type of the reference tag comprises extracting features of the reference tag. ### Claim 12 (depends on 11) The computer program product of claim 11, wherein the features include at least one of: a barcode; a Quick Response (QR) code; an address; a postage stamp; an indicia; a logo; and a format or layout of content included on the reference tag; ### Claim 13 (depends on 9) The computer program product of claim 9, wherein the image is received from a user device hosting an application for measuring the item based on capturing the image of the item. ### Claim 14 (depends on 9) The computer program product of claim 9, wherein the reference tag is affixed to the item. ### Claim 15 (depends on 14) The computer program product of claim 14, wherein the reference tag includes at least one of: a shipping label; a standalone label; and a three-dimensional object. ### Claim 16 A system comprising: a processor, a computer readable memory, a non-transitory computer readable storage medium associated with a computing device, and program instructions executable by the computing device to cause the computing device to perform operations comprising: receiving an image of an item and a reference tag; identifying a perimeter of the item; identifying a type of the reference tag; identifying known dimensions of the reference tag based on the type; determining dimensions of the item in standardized units based on the known dimensions of the reference tag; and outputting information identifying the dimensions of the item. ### Claim 17 (depends on 16) The system if claim 16, wherein the determining the dimensions of the item further comprises: determining a length represented by each pixel in the image based on the known dimensions of the reference tag; determining the dimensions of item in the form of pixels in the image; and converting the dimensions of the item in the form of pixels to the standardized units based on the length represented by each pixel. ### Claim 18 (depends on 16) The system if claim 16, wherein the identifying the type of the reference tag comprises extracting features of the reference tag. ### Claim 19 (depends on 11) The computer program product of claim 11, wherein the features include at least one of: a barcode; a Quick Response (QR) code; an address; a postage stamp; an indicia; a logo; and a format or layout of content included on the reference tag; ### Claim 20 (depends on 16) The system if claim 16, wherein the image is received from a user device hosting an application for measuring the item based on capturing the image of the item.
