Definitions

  • the invention relates to an apparatus for recognizing address information on physical mail, the apparatus comprising a camera, a recognition surface for mail to be placed onto it, and a housing, to a process for recognizing address information on physical mail, and to a system for distributing physical mail to a recipient.
  • CN 103763451 A discloses a solution using a point light source shining on an envelope at a certain angle of about 45°, wherein the bright spot which is the reflection of the point light source is eliminated by the technology disclosed in this reference.
  • EP 12 57 954 B1 discloses a method for distributing mail.
  • DE 198 01 246 A1 discloses a method for detecting windows for address information in envelopes by detecting a reflection of the window from different angles.
  • US 2001/0019619 A1 discloses a solution using two point light sources shining on an envelope at a certain angle of about 45° and causing reflections.
  • WO 2009/095602 A1 discloses a system for acquiring images for identifying signs on postal packages.
  • FR 2 926 899 A1 discloses a device for acquiring images of postal items comprising fluorescent and contrast marks.
  • FR 2 895 820 A1 discloses a postal parcel image acquisition device for use in postal sorting machine that has LEDs including light radiations that illuminate address information visible by contrast and with fluorescent mark in zones of window, respectively.
  • the problem of the present application is to provide a technology to overcome the shortcomings of the prior art.
  • an apparatus especially for recognizing address information on physical mail, comprising a camera, a light source, a recognition surface for mail to be placed onto it, and a housing for blocking light entering an interior of the housing,
  • Another advantage of the housing lies in the avoidance of stress being caused in the workforce due to extreme light exposure.
  • optical axis of the camera is arranged relative to the recognition surface at an angle in a range of from 80° to 100°.
  • the camera has a focal length in a range of from 2 to 10 mm.
  • This rather short focal length ensures that the camera can capture the whole recognition surface and at the same time be as close as possible to the recognition surface in order to avoid any extra stray light or reflections entering the camera.
  • the focal length is too long, the distance of the camera to the recognition surface must be increased, which in turn may result in a higher probability of additional stray light or reflections entering the optical path into a lens system (for example an objective) of the camera on its way from the recognition surface to the lens system of the camera. This has been found to be one of the important features when it comes to optimizing recognition quality.
  • the aperture of the camera is a in a range of from 1.5 to 4. Below this range, the camera may not reliably reproduce sharp images for varying thickness of pieces of physical mail. Above this range, it may be the case that not enough light enters the camera in order to yield an image with the type of quality required for reliable OCR processing.
  • the distance between an outermost lens of a lens system of the camera and the recognition surface is in a range of from 15 cm to 100 cm, more preferably in a range of from 20 cm to 50 cm.
  • the lens system may be an objective. It was found that this distance had the advantage of being able to, on one hand, capture an image of the whole piece of physical mail and, on the other hand, still provide sufficiently uniform illumination allowing for the achievement of an optimum of image quality.
  • the outermost lens of the lens system of the camera has a diameter of 30 to 70 mm.
  • the camera has a rolling shutter. This has been shown to improve recognition results.
  • the camera is a digital camera.
  • a digital camera has the clear advantage of being able to easily automate the recognition of address information. Below said range, the image quality may be insufficient for accurate recognition of address information. Above this range, computing the image information and extracting address information may be inefficient.
  • the camera and the lens system of the camera are selected such that the camera captures at least the whole area of the recognition surface.
  • the outermost lens of the lens system of the camera has a polarizing filter attached to it. It has been found that reflections and unwanted bright spots in the captured image can be further minimized this way.
  • the camera does not generate a black & white image. More preferably, the camera generates a color image. This has the advantage that indicators such as priority mail can be recognized by the system according to the present invention based on their shape and color.
  • the camera has a fixed focus.
  • the lens system in the form of the objective is set to a specific focus. This has been found to make the overall performance much more robust and more tolerant to handling errors.
  • the focus of the camera is set to a distance in a range of 0.5 to 5 mm from the recognition surface. This has the advantage that the surface of the mail to be recognized - depending on the thickness of the piece of mail - can have varying distance from the recognition surface.
  • the angle of the optical axis of the camera to the recognition surface is in a range of 85° to 95°, most preferably 90°. It has been found that angles outside the preferred range may result in unwanted reflections and other optical errors in the captured image.
  • the illumination uniformity u of the light source is in a range of 0.8 to 1, more preferably in a range of 0.9 to 1, and most preferably in a range of 0.97 to 1.
  • Illuminance is the total luminous flux incident on a surface measured in lux (Ix) or lumens per square meter (cd ⁇ sr ⁇ m -2 ). It has been found that one key to eliminating unwanted reflections on the physical mail is uniform lighting incident on the physical mail.
  • the light source is not a point light.
  • the light source is not a flash light.
  • point lights such as spot lights or flash lights generate unwanted bright spots in the resulting image captured by the camera that need to be removed by complicated and inefficient techniques.
  • the light emitting surface of the light source is planar. More preferably, the light source is a light panel, even more preferably an LED light panel, and most preferably an organic LED light panel. Especially with organic LEDs (or OLEDs), very uniform area light sources such as panel lights can be achieved. As mentioned before, it has been found that uniform lighting is a key factor to efficient recognition of address information on physical mail.
  • the light source is an LED light.
  • LED light has the advantage of less heat development. Compared to the aforementioned solutions of the prior art, the inventors found that they do not need complicated heat dissipation or ventilation solutions.
  • the light source is arranged around the outermost lens of the lens system of the camera; more preferably the outermost lens of the lens system of the camera is completely encircled by the light source.
  • the light source is a light panel with a hole in the center that fits the size of the lens of the camera.
  • the smallest distance of the light source from the recognition surface deviates less than 10%, more preferably less than 5%, from the distance of the outermost camera lens of the lens system from the recognition surface. Said distance has been found to further eliminate bright spots and unwanted reflections in the captured image of the camera.
  • the center of the lens of the lens system of the camera deviates less than 10 mm, more preferably less than 2 mm, from a straight line extending perpendicular from the center of the light source.
  • the center of the outermost lens of the lens system of the camera deviates less than 10 mm, more preferably less than 2 mm, from the center of the light emitting surface of the light source.
  • the area of the light emitting surface of the light source is in a range of 200 to 1500 cm 2 .
  • the light emitting surface of the light source has a polarizing filter attached to it. It has been found that reflections and unwanted bright spots in the captured image can be further minimized this way. More preferably, this polarizing filter is a foil.
  • the optical angle between the polarizing filter attached to the camera lens and the polarizing filter attached to the light source is in a range of 10° to 80°, more preferably in a range of 20° to 70°.
  • the light source emits collimated light.
  • the inventors have found that this is an important factor for eliminating unwanted reflections and bright spots in the image captured by the camera.
  • the angle between the optical axis of the camera and a straight line through an intersection point, where this optical axis intersects the recognition surface, and any point of the light emitting surface of the light source is in a range of 0.1° to 40°, more preferably 0.3° to 30°.
  • the inventors have found that - especially in combination with the above mentioned collimation and/or the polarizing filters and/or anodized side walls - this is a very important feature for achieving optimal image quality for address information recognition.
  • the area of the recognition surface is in a range of 200 to 1500 cm 2 .
  • the area of the recognition surface is larger than the area of the light emitting surface of the light source. More preferably, the area of the recognition surface is 2% to 20% larger than the area of the light emitting surface of the light source.
  • the light source points toward the recognition surface.
  • the light emitting surface of the light source is arranged in a first plane.
  • the recognition surface is arranged in a second plane.
  • the first plane is arranged relative to the second plane at an angle of less than 1°.
  • the distance between the light emitting surface of the light source and the recognition surface is in a range of 15 cm to 100 cm, more preferably in a range of 20 cm to 50 cm. It has been found that this distance has the advantage of, on one hand, enabling the camera to capture an image of the whole piece of physical mail and, on the other hand, still providing sufficient even lighting allowing for the achievement of an optimum of image quality.
  • the light source is located within the housing.
  • the light source is positioned within the top 10% of the height of the housing. This way the light source is located near the top of the housing.
  • the inner surface of the housing has in antireflective surface.
  • the inner surface of the housing is black.
  • the inner surface of the housing has an arithmetic average surface roughness R a in a range of 0.2 to 2 ⁇ m as measured by VSI (vertical scanning interferometry).
  • the inner surface of the housing is made of an anodized metal, especially aluminum.
  • at least the inner surface of the side walls of the housing between the light source and the recognition surface exhibit one of more features as mentioned in this paragraph.
  • the inner surface of the side walls of the housing between the light source and the recognition surface is black and made of anodized aluminum.
  • the side walls of the housing extend at least from the recognition surface to the light source.
  • the side walls of the housing have a hole or opening for placing physical mail onto the recognition surface.
  • the opening may preferably be a slit formed by the side walls of the housing, the front plate as well as the recognition surface.
  • This hole may be closeable by a door or flap.
  • the area of the hole in the side walls is in a range of 2 to 7% of the area of the side walls.
  • the area of the hole is in a range of 100 to 500 cm 2 . Below these ranges, the hole may be too small to fit all typical sizes of physical mail onto the recognition surface. Above these ranges, too much stray light may enter the inside of the apparatus and deteriorate the image quality of the camera.
  • the hole has a height in a range of 2 to 15 cm.
  • the hole has at least one straight edge, wherein that edge is adjacent to one edge of the recognition surface.
  • the side walls have no further opening or hole between the recognition surface and the outermost camera lens except for the above mentioned hole between the recognition surface and the camera lens.
  • the distance between the recognition surface and the side walls of the housing is in a range of 0 to 2 mm.
  • the advantage resulting from this is less physical mail getting lost by falling into the gap between the housing and the recognition surface.
  • the housing has a touchscreen attached to the outside of the housing. This makes control of the apparatus and the whole system much easier.
  • the problem according to the present invention is solved in another embodiment by a process for recognizing address information on physical mail comprising the step of recognizing the address information using an apparatus according to the present invention.
  • location of the address information on the physical mail is part of this process. More preferably, location of the address information on the physical mail is not accomplished by finding reflective parts of the surface of the physical mail that could indicate a window in an envelope.
  • the goal of the present invention is to eliminate any source of reflection in the captured image. More preferably, location of the address information on the physical mail is accomplished by OCR (optical character recognition) in the image captured by the camera and subsequent search for indicators in a block of text such as typical personal names, streets, postal codes, city names, country names, and then defining a block of text containing one or more of these indicators as the location of the address information.
  • OCR optical character recognition
  • an image of the physical mail is captured and preferably stored.
  • the piece of physical mail is identified in the image and preferably an image of just the piece of physical mail is extracted.
  • this is achieved by finding the largest closed contour on the captured image and this contour is cut out as the image of just the piece of physical mail.
  • this image of just the piece of physical mail is rotated around the center of the image.
  • the location of the address information (e.g. the address window) is determined in the image of just the piece of physical mail.
  • the located address information is cut out as an image of the address information.
  • the image of the address information is processed with text recognition to obtain the text of the address information.
  • the problem according to the present invention is solved in another embodiment by a system for distributing physical mail to a recipient, characterized in that the address of the recipient on the physical mail is recognized using an apparatus according to the present invention and then the mail is delivered to the recipient physically or electronically (e.g. after opening the physical mail and scanning).
  • the physical mail is not transported automatically to the recognition surface.
  • the physical mail is recognized using an apparatus according to the present invention when it arrives at the mail distributing facility.
  • the mail distributing facility according to the present invention can be a company with a plurality of potential mail recipients (e.g. very large companies with hundreds or thousands of employees at one location) or a mail distribution center of a logistics company (e.g. a postal company).
  • certain actions can be taken after recognizing the physical mail with the apparatus according to the present invention. These actions are not limited to, but can be selected from, the group of rush delivery, courier delivery, rerouting, opening, digitalizing, destruction, pre-filling of datasets or forms based on the recognized information, printing of labels or any sensible combination thereof.
  • these rules can be determined by the recipient.
  • the recipient is presented with these options as a menu of selectable items or buttons in a computer program, a web application, a smartphone application or an intranet application.
  • the system recognizes confidential physical mail (e.g. by finding words like "confidential" on the envelope) and overrules any rules established by the recipient and delivers the physical mail to the recipient without opening or scanning the mail.
