Abstract
Abstract A system for the sorting of parcels as they move on a conveyor in a sorting establishment of a Post Office or of a parcel delivery company. The system is capable of locating the label on the parcel bearing data of the adressee, and establish its dimensions. The coordinates of the label are determined by a low magnification camera, and scanning cameras are used for a sharp line scan of the data on the label, means being provided for desplaying the data and for ultimately sorting the parcels according to the said data. There is also provided a method for sorting parcels moving on a conveyor belt by acquiring the data on the relevant label and using the data for the sorting of the parcels according to their destination.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
122 words
A system for locating a relevant label bearing data of the addressee on a parcel and for its high resolution display, while said parcel moves on a conveyor belt, and for optionally determining the dimensions of such parcel, which comprises the stages of: a. determining the coordinates of the outline of the parcel and the outline of the relevant label by means of a low magnification camera and determining the height of the parcel by a suitable sensor; b. actuating one or more high resolution scanning cameras according to the determination of the label location and speed of movement on the conveyor so as to provide a sharp line scan of said label, and displaying the image thereof at any desired location.
Claim 2
Dependent Claim
43 words
A system according to claim 1, where the surface of the moving conveyor band is scanned by means of a scanning mirror, picture acquisition of the relevant label being actuated when required according to the determination of label position on the moving parcel.
Claim 3
Dependent Claim
22 words
A system according to claim 1 or 2, where the height of the parcel is determined by means of an ultrasonic sensor.
Claim 4
Independent Claim
43 words
A system according to any of claims 1 to 3, which comprises a CCD camera for label coordinate detection, an acoustic sensor for height determination and a high resolution camera enabling a high resolution line scan imaging the area of the relevant label.
Claim 5
Independent Claim
75 words
A system according to any of claims 1 to 4, comprising means for acquiring at a short time interval two images of the parcel moving in a linear motion on the conveyor, means for obtaining a subtration image of said images, and means for deducing from said subtraction image the outer edges of the parcel and the location and size of the relevant label, and means for providing a high resolution image of said label.
Claim 6
Independent Claim
15 words
A system according to any of claims 1 to 5, interfaced with a OCR system.
Claim 7
Independent Claim
22 words
A system according to any of claims 1 to 6, comprising means for reading a bar code, if present on the parcel.
Claim 8
Independent Claim
17 words
A system according to any of claims 1 to 7, provided with means for remote video encoding.
Claim 9
Independent Claim
46 words
A system for the determination of the location of a relevant label on a parcel moving on a conveyor, for determining parcel dimensions and for forming a sharp image of such label at a desired location, substantially as hereinbefore described and with reference to the Figures.
Claim 10
Independent Claim
84 words
A method for locating a relevant label at the upper surface of a parcel moving on a conveyor and for optionally determining the dimensions of the parcel which comprises determining the level of the said upper surface above the level of the conveyor, focusing a camera on the surface of the parcel, acquiring at the correct moment the image of the said relevant label and scanning the label, resulting in a high resolution image of the label, and evaluating the data on said label.
Claim 11
Dependent Claim
33 words
A method according to claim 10, which comprises scanning the surface of the parcel by a moving mirror, and projecting the image of the label at the correct instant to suitable display means.
