摘要： A checkout system for data reading, and related methods of use, the checkout system including one or more data reading devices with a conveyor for transporting items toward a read zone of the data reading devices, and an exception identification system capable of identifying exception items transported through the read zone without being successfully identified by the data reader. The checkout system includes an exception handling system operable to receive exception handling input for resolving an exception associated with the exception item, and a feedback system for receiving the exception handling input and determining whether and how to adjust an object recognition model of the data reading devices to improve performance.

摘要： A system and method for calibrating a barcode scanning tunnel comprises providing a scanning tunnel having a moveable surface, a camera, and a dimensioning device. Orientations of the dimensioning device and camera are estimated. Instances of a calibration object on the moveable surface are acquired by the dimensioning device and the camera, and a relationship is defined between the two devices. A calibration object is moved along the moveable surface through the devices' fields of view, controlling the camera's focal distance according to the relationship, so that the dimensioning device and the camera acquire instances of the calibration object, and the relationship is revised.

摘要： Visual codes are scanned to assist navigation. The visual code may be a Quick Response (QR) code that contains information useful to calibrating a variety of navigation-based sensors such as gyroscopes, e-compasses, and barometric pressure sensors. In an embodiment, an imaging device, an e-compass, an accelerometer, and a processor are elements of a system. The processor is coupled to the imaging device, the e-compass, and the accelerometer. The processor causes the imaging device to scan a visual code, read a yaw angle from the visual code, and computes an estimate of a yaw angle based on magnetic field measurements taken by the e-compass. The processor generates scale factors and biases determined from measurements generated by the e-compass. Based on scanning the visual code, the processor computes a quality factor based on the yaw angle read from the visual code and the estimate of the yaw angle.

摘要： Method of and system for reading bar code symbols using a hand-supportable laser scanning bar code symbol reading system supporting an improved level control over the length of laser scan lines projected onto scanned objects, at any instant in time, in a manner dependent the detected location, distance or range of the scanned object in the scanning field of the system during system operation. The length characteristics of the laser scan line are controlled by setting the laser scan sweep angle as a function of detected or estimated distance or range of the object from the system. In the illustrative embodiment, the laser scan sweep angle is controlled by supplying a drive current to the scanning mechanism, as a function of detected or estimated distance or range of the object from the scanning system.
