Other advantageous features will be apparent from the accompanying claims.
Following is a brief description of the drawings in order to make the invention more readily understandable, the discussion that follows will refer to the accompanying drawings, in which
In the following it is firstly disclosed general embodiments in accordance with the present invention, thereafter particular exemplary embodiments will be described. Where possible reference will be made to the accompanying drawings and where possible using reference numbers in the drawings. It shall be noted however that the drawings are exemplary embodiments only and other features and embodiments may well be within the scope of the invention as described.
In the following description it will be adhered to the definitions below:
Erroneous registration of goods at checkout counters is a problem. Customers may deliberately or by accident cover codes to be registered, such as bar codes, QR-codes or other “visual” codes. Double registration may also occur etc.
Means which have the ability to sense motion of arms and/or hands can provide additional certainty when scanning/registering goods at a checkout counter. Motion detectors can be supported by optical colour sensors for detecting human skin and/or they can be supported by temperature detecting devices such as infrared temperature measurement devices. Infrared sensors are noncontacting and they infer temperature by measuring the thermal radiation emitted by a material.
Video cameras used for detection of motion is essentially a combination of camera hardware including any camera motors for manipulating camera position and software for processing of images received from the cameras. In principle motion detection in its simplest form includes a comparison between pixels in two or more subsequent digital images. Unchanged pixels between subsequent digital images indicate that “nothing has happened” whilst changed pixels indicates a change. By analysing numerous subsequent pictures in a row a pattern of movement can be predicted and also the object or objects that have moved can be predicted. The latter for example by comparison with known pattern, i.e. the pixel pattern off sudden objects and particular movements have been taught to the system, i.e. processor and memories. In an adaptive system a library of pixel pattern associated with particular objects and/or movements will be built over time.
Mathematic analyses of expected pixel patterns based on previous patterns may help in the analyses of received image data from the one or more cameras. Obviously a combination of cameras and laser scanners or LIDAR's can be used for motion detection.
Motion recognition can be an integral part of the registration means, registration means such as optical scanners may be configured to additionally detect motion. The registration means and the motion sensors may be based on different technology, but still be housed within the same cabinet/housing. Motion recognition/detection/scanning can be effected by photographic analysis, measurement of returned light in the divided zones, in that one or more photo barriers wrap or similar methods commonly known for detecting a movement beyond a point or region. The movement direction may also be determined by the motion detectors.
The product scanning/registration as such is described below with reference to
A restricted area within the registration area of a checkout counter is suitable for the detection of motion. An example of such an area is indicated as E in
Upon detection of a motion indicating that an item is moved through the detection area E, the system will check that a commodity detection have been carried out and registration of goods between the entrance to the detection area marked “A” and the exit of the detection area indicated by the arrow marked “C”. The control can alternatively be carried out using one or more sensors, where aggregate information regarding motion/movement and identification/registration of goods are compared or grouped together so as to reveal whether goods are registered correctly or an item is moved past the registration zone without being registered, as indicated above
A signal indicating the status of registration can be provided using light signals, audio signals and/or the registration status is transferred to other systems (payment station/system), so that the customer and/or cashier and/or other required recipients of the information can access it.
In one embodiment the customer can get a red light at the erroneous/missing registration and cashier gets a notice of the same on his screen. Correspondingly a correct registration can trig a green light and the item shows up in the payment system as being correctly registered. Obviously indication of erroneous registration and correct registration may be indicated differently from what is mentioned above, the goal is to indicate erroneous and correct registration in a manner which can be handled by the operators of the registrations means, such as the cashier.
A typical checkout counter comprises three areas, the present counter differs in the way the centre area 102 is designed. In particular so by the introduction of one or more motion detectors 125, 126. In accordance with embodiments of the present invention the centre area, registration zone 102, is combined with packing area 103 and loading area 101. The centre area is the registration area. According to one embodiment in addition to the typical cashier's registration means the checkout counter according to the present invention is provided with a second parallel registration zone 207 that can be used by a customer in such a way that they can independently register their own goods against their own purchases. In another embodiment the registration zone is a self-service zone which includes one or more motion detectors 125, 126.
The registration area can be built up with one or two roller paths or conveyor belts. These may be operating freely or synchronously between the customer and cashier. Any feed mechanism may be controlled manually or via a computer system, typically referred to as the Point of Sale (POS) system.
The registration area is designed to transmit item registrations from each of two fields into each of their ongoing purchase registrations, or to combine the registrations into a single purchase, into a POS system or in such a way that one or more zones can be in a payment queue after they are completely registered. This enables the registration process to continue with one or more outstanding payments related to purchases in the packing area.
The checkout counter can be fitted with a turntable packing area 103, which allows for multiple purchases to accumulate in zones 208 according to the output from the registration area 102. The turntable packing area 103 may have zones 208 of varying/flexible size in order to be adaptable to varying package volumes per purchase. Also, the position of these zones can be read into the POS system so that the registration/scanning process is stopped or only allowed into the correctly set zone, based on zones positioned against the registration area and the respective detection zones.
The payments may be self-serviced or performed as any common payment performed by the cashier. For example, a customer could pay his buy/zone with his payment cards on his own, while another customer pays for his purchases/zone to the cashier.
According to one embodiment of the invention it is provided a POS system that can simultaneously manage sales for at least the number of concurrent checkout zones that the counter is physically built to handle. The cashier will through the POS system have full overview of all the zones, any ongoing registrations per zone and any ongoing or closed sales and payments. The cashier may also according to desired security settings verify, change or delete registrations made per zone.
The POS system may have logic for random control of customer registrations per an arbitrary number of registrations to reduce the risk of fraud and erroneous registrations, in the same way as common in so-called self-scanning checkout solutions. Also regulatory controls can be made, like verifying the customer's age when needed and for limiting sales outside an allowable time period.
The first area, called the “loading” area 101 may according to one embodiment be designed as a rotatable unit or roundtable disc which physically resembles a rotatable disc in the packing area 103 or be single rollers based or use conveyor belt. The loading area 101 is directly in communication with the registration area 102 registration zones 206, 207.
Returning to
The area marked as “D” in the figure indicates a combined scanner and two laser/light rays (“F” and “H”) for motion detection. It shall be appreciated that one or more extra laser/light rays can be added for motion detection. The number of motion detectors is partly governed by the design, layout and size of the registration area and the interface between the registration area and the packing area. The combination of commodity registration/identification and detection/identification of the movement of one or more arms utilises motion detectors. Correct registration of goods either by a customer or a cashier can be verified by a combined registration and motion recognition system according to the present invention. By way of illustration a sequence of registration can be shown as a binary shift as is shown in table 1 below. The detection areas can be divided into detection zones as is illustrated in
The detection zones F, G and H overlap to create the following combined detection zones:
If a commodity is moved from left side in
Open boxes or X, can be any of «1», «0» or “Z” dependent on configuration.
By configuring a CPU one can teach the CPU “correct” and “wrong patterns”. The table does not take into account the speed of the commodity or an arm movement. Obviously a speed component in both X (Vx) and y (Vy)-direction can be calculated, and thereby a “real” speed vector.
By combining speed pattern calculation with the bit pattern signature one can in a reliable way indicate erroneous and correct scanning of goods. The simple layout of detection zones E1-E6 above gives 64 different bit patterns (26), adding the speed component will increase the reliability. Moreover, if the goods are conveyed by a conveyor belt they will typically have a known speed, VX, before being manually handled or before they end up in “congestion” due to too many goods on the conveyor belt.
A system as indicated above which not only detects motion but the character—speed and direction—of the motion can typically be configured adaptively. That is, one can teach a CPU with memory valid and not valid bit pattern signatures and speed component signatures.
In a more primitive version the system can be semi adaptive or fixed. The latter will use fixed logic circuitry which is preprogramed by a manufacturer/vendor, ASICS can be a candidate for use in a fixed system. A semi adaptive system can include FPGAS which have to be programmed by technicians/service personnel.
The speed of a conveyed commodity can be calculated by knowing distances (ds=√{square root over ((dx2)}+dy2)) between measure points (ref calculation of velocity components above), the timing between measure points can be calculated by counting a number of clock cycles of a system clock.
By adding additional motion detectors one can achieve even more reliable motion detection data—adding one motion detector doubles the possible combinations (in this example from 26 to 27).
It shall be noted that the practical example is a simplified example and in practical life a single laser barcode scanner or omnidirectional laser scanner can be configured to be used in a motion detecting mode, for example periodically after a sudden number of clock pulses. A laser barcode scanner uses a single laser source which in combination with a moving mirror or prism generate a “line” of light. This line of light can be used to detect moving objects by reading reflected light sent from the barcode scanner. An omnidirectional bar code scanner is in principal a number of single laser barcode scanners arranged in for example a star shaped fashion. The omnidirectional scanner may be used as a motion detecting device on its own or in combination with other motion detecting means 125, 126.
