Abstract: A system and method of detecting an image of a template object in a captured image may include comparing, by a processor, an image model of an imaged template object to multiple locations, rotations, and scales in the captured image. The image model may be defined by multiple model base point sets derived from contours of the imaged template object, where each model base point set inclusive of a plurality of model base points that are positioned at corresponding locations associated with distinctive features of the imaged template object. Each corresponding model base point of the model base point sets may (i) be associated with respective layers and (ii) have an associated gradient vector. A determination may be made as to whether and where the image of the object described by the image model is located in the captured image.

Abstract: A retail store self-checkout area may include a scanner configured to enable a shopper to scan items being purchased. A bagging area may be positioned at the scanner. A top-down facing camera positioned and oriented to image a shopping cart or basket at the self-checkout area and to generate image signals of the shopping cart or basket. A projector may be configured to project dynamically alterable illumination signals onto a surface visible to the shopper when at the self-checkout area to provide visual guidance information to the shopper. The projector may be a smart projector, and may be configured to be a top-down facing projector to illuminate a floor at the self-checkout area. A system controller may be configured to drive the projector (e.g., smart projector) and to process images captured by camera to identify errors or fraudulent behavior during a self-checkout process.

Abstract: A method of acquiring images of an object arranged on a supporting surface includes providing at least one optical image acquisition apparatus of the object provided with an optical axis; in a work step of the optical apparatus an acquired image is processed to correct a possible perspective distortion of the image and at least one feature of the object is extracted from the processed image. The method further includes associating a known reference plane with the object and, in a configuration step of the optical apparatus preceding the work step, obtaining a corresponding inclination between the reference plane and the optical axis; processing the acquired image in fact comprises identifying a processing mode determined as a function of the corresponding inclination and applying this preset processing mode to correct the possible perspective distortion.
Abstract translation: 获取布置在支撑表面上的物体的图像的方法包括：提供具有光轴的物体的至少一个光学图像获取装置; 在光学装置的工作步骤中，处理获取的图像以校正图像的可能的透视失真，并且从处理的图像中提取对象的至少一个特征。 该方法还包括将已知参考平面与对象相关联，并且在工作步骤之前的光学设备的配置步骤中，获得参考平面和光轴之间的对应倾斜度; 处理所获取的图像实际上包括识别作为相应倾斜度的函数确定的处理模式，并应用该预设处理模式以校正可能的透视失真。

Abstract: A retail store self-checkout station may be configured to support a number of different sensing features, including (i) status (e.g., empty, not empty, occluded) of a shopping cart or shopping basket, (ii) customer behavior (e.g., potentially shoplifting or committing fraud at the checkout station, and (iii) machine-readable indicia (e.g., barcode) reading error or fraud. If an occlusion of the shopping cart or shopping basket exists, an advanced shopping cart structure and content analyzer may identify that an item is still in the shopping cart or shopping basket via openings defined by a mesh wall thereof.

Abstract: The disclosure relates to a data reading system and method for obtaining target data from an image. The data reading method includes obtaining an image containing the target data, and identifying a starting pixel coordinate on the image. The method further includes determining an initial local threshold value based on the selected starting pixel and analyzing the image to detect one or more high contrast boundaries or contours. After detecting the boundaries, the method includes analyzing the one or more boundaries to identify the target data in the image.
