摘要： An efficient and reliable method and apparatus is disclosed that finds a reference point of an object profile within an image when the object is of an unknown size. The object profile is modeled using a synthetic labeled-projection model, which in conjunction with the image, is projected over a portion of the image of the object profile to derive a histogram. The histogram is normalized and a maximum of a first derivative of the histogram is defined for that position. The position of the labeled-projection model is moved relative to the image, and the process is repeated until a selected portion of the image has been examined. The first derivative of the normalized labeled projection is greatest when a feature of the image and the feature denoted by a specific synthetic label of the labeled-projection model are aligned. The method and apparatus can locate the center of the object with reliability, because use of the labeled-projection model and the histogram minimizes the * effects of image artifacts. Further, the method decreases computational time, and thus, increases performance speed.

摘要： Methods and apparatuses are disclosed for defining a locus of viable points on an elongated object, such as a locus of viable bond points on a lead of a lead frame. The locus guides the bond point positioning of a wire bonder so that the number of unacceptable wire bonds is reduced. The locus is a region adapted to receive a bond, and is defined such that for any bond centered therein, the probability of forming an unacceptable bond is reduced by offsetting the locus from at least a portion of the lead edge(s) by a minimum-offset distance. The minimum-offset distance is based on various factor(s), such as user tolerance and bond width. Further, the definition of the locus is independent of lead shape, and consequently works with a variety of lead shapes. The locus can also have various shapes for a single lead, and the shapes can vary depending on the application. The method and apparatus herein disclosed describe a variety of methods to detect the leads and define the size, position, and shape of the locus during training. Preferably, the lead tip is also detected so that the locus can be defined based on an offset from the front of the lead. During operation, characteristics of the locus and/or the target bond point are used to relocate the lead and refine the target bond/point before bonding. Alternative embodiments disclosed include inspecting the leads.
摘要翻译：公开了用于定义细长物体（例如引线框架的引线上的可行接合点的轨迹）的可行点的轨迹的方法和装置。轨迹引导引线接合器的接合点定位，使得不可接受的引线键合的数量减少。轨迹是适于接收键的区域，并且被定义为使得对于以其为中心的任何键，形成不可接受的键的概率通过将引线边缘的至少一部分偏离最小值偏移距离最小偏移距离基于各种因素，如用户容差和粘合宽度。此外，轨迹的定义与铅的形状无关，因此可以使用各种铅的形状。该轨迹还可以具有用于单个引线的各种形状，并且形状可以根据应用而变化。本文公开的方法和设备描述了在训练期间检测引线并定义轨迹的大小，位置和形状的各种方法。优选地，也检测引线尖端，使得可以基于与引线的前部的偏移来定义轨迹。在操作期间，使用轨迹和/或靶键点的特征来重新定位引线并在键合之前精炼目标键/点。公开的替代实施例包括检查引线。

摘要： A system and method for object inspection incorporates a level of hierarchy so that a single, primary alignment may be performed to generate a pose for multiple inspection regions. As a result, a Training mode may include the specification of a single alignment model window and a list of associated inspection region windows. Similarly, a Run-time Inspection Mode may also include specification of a single alignment model window and a list of associated inspection region windows. Such an implementation addresses the long standing problems associated with performing one or more types of inspection operations in one or more regions of a given sample-object image. By virtue of the hierarchical structure, operation of multiple inspection tools may be performed simultaneously or in any order and inspection of multiple inspection regions may be performed simultaneously or in any order.
