A system and method of determining an initial point for a scan path may include acquiring, using a mobile device, an image of an object, the image comprising decodable indicia. Using the mobile device, data is decoded from the decodable indicia. Indicia dimensions of the decodable indicia are determined based on the data, and image dimensions of the decodable indicia in the image are determined. An initial location of the mobile device is calculated relative to the decodable indicia based on a geometric relationship between the indicia dimensions of the decodable indicia and the image dimensions of the decodable indicia in the image.

1. A method comprising: acquiring, using an electronic device, an image of an object, the image comprising decodable indicia;decoding, using the electronic device, data from the decodable indicia;determining indicia dimensions of the decodable indicia; anddetermining an initial location of the electronic device relative to the decodable indicia by determining a distance of the electronic device from an origin using decodable indicia dimension data decoded from the decodable indicia. 2. The method according to claim 1, wherein determining the distance location comprises determining coordinates of a location indicating an initial location of the electronic device. 3. The method according to claim 1, wherein the determining the distance of the electronic device from the origin comprises: determining an x distance of the electronic device from the origin using the decodable indicia dimension data decoded from the decodable indicia; anddetermining a y distance of the electronic device from the origin. 4. The method according to claim 1, further comprising determining an orientation of the electronic device. 5. The method according to claim 1, further comprising determining an orientation of the electronic device based on an orientation of one of the decodable indicia in the image or based on an orientation of the object in the image. 6. The method according to claim 1, further comprising analyzing the image for errors and correcting the errors. 7. The method according to claim 6, wherein the analyzing comprises checking for errors of the image, correcting the errors using correction factors, and storing the correction factors, wherein the errors comprise at least one of keystone effect errors of the image, rotation errors of the image, or perspective errors of the image. 8. The method according to claim 1, wherein the determining the distance of the electronic device from the origin is indicia based on a geometric relationship between indicia dimensions of the decodable indicia and image dimensions of the decodable indicia in the image. 9. The method according to claim 1, wherein the object comprises one of a shelving unit, a clothing rack, or a table. 10. The method according to claim 1, wherein the decodable indicia comprises one of a bar code or a radio frequency identification (RFID) tag. 11. The method according to claim 1, further comprises determining image dimensions of the decodable indicia in the image wherein the determining of image dimensions of the decodable indicia in the image comprises measuring a number of pixels in the image comprising the decodable indicia to calculate a physical relationship between a location of the electronic device and the decodable indicia based on the indicia dimensions of the decodable indicia. 12. A method comprising: acquiring, using an electronic device, an image of an object, the image comprising decodable indicia; decoding, using the electronic device, data from the decodable indicia; determining indicia dimensions of the decodable indicia based on the decoding of the decodable indicia;determining image dimensions of the decodable indicia in the image; calculating an initial location of the electronic device relative to the decodable indicia based on a geometric relationship ratio between the indicia dimensions of the decodable indicia to the image dimensions of the decodable indicia in the image, andmultiplying-a base distance by the ratio to determine a distance of the electronic device from the decodable indicia. 13. The method according to claim 12, wherein the initial location comprises coordinates of a location indicating a beginning reading point of the electronic device. 14. The method according to claim 12, wherein the calculating an initial location of the electronic device comprises: determining an x distance of the electronic device from an origin using decodable indicia dimension data decoded from the decodable indicia; and determining a y distance of the electronic device from the origin. 15. The method according to claim 12, further comprising: analyzing the image for errors and correcting the errors by checking for errors of the image,correcting the errors using correction factors, and storing the correction factors, wherein the errors comprise at least one of keystone effect errors of the image, rotation errors of the image, or perspective errors of the image. 16. The method according to claim 12, wherein the decodable indicia comprises one of a bar code or a radio frequency identification (RFID) tag, and wherein the object comprises one of a shelving unit, a clothing rack, or a table. 17. The method according to claim 12, wherein the determining image dimensions of the decodable indicia in the image comprises measuring a number of pixels in the image comprising the decodable indicia to calculate a physical relationship between a location of the electronic device and the decodable indicia based on the indicia dimensions of the decodable indicia. 18. The method according to claim 12, wherein the determining indicia dimensions comprises scanning the decodable indicia to obtain data indicating the indicia dimensions of the decodable indicia. 19. The method according to claim 12 wherein the determining image dimensions comprises detecting one or more edges of the object within the image. 20. An electronic device comprising: a hardware processor configured for:acquiring an image of an object, the image comprising decodable indicia;decoding data from the decodable indicia; wherein indicia dimensions of the decodable indicia are determined, and image dimensions of the decodable indicia in the image are determined, and wherein an initial location of the electronic device is calculated relative to the decodable indicia based on a geometric relationship between the indicia dimensions of the decodable indicia and the image dimensions of the decodable indicia in the image by: determining an x distance of the electronic device from an origin using decodable indicia dimension data decoded from the decodable indicia; and determining a y distance of the electronic device from the origin.
