Abstract: A method is provided for inspecting a device comprising a plurality of bristles. During this method, image data provided from an electronic optical sensor is received. The image data is indicative of an image of at least a portion of the bristles. A bristle configuration (e.g., an angle) of at least one of the bristles (e.g., an average bristle) in the image is determined by processing the image data with a computer processor

Abstract: A system includes a laser-line imaging subsystem to measure a feature. The laser-line imaging subsystem includes a laser to project a laser-line, and a digital video camera mounted at an angle with respect to an axis of said laser to obtain an optical image of the laser-line. A control subsystem is operable to compute three-dimensional coordinate points via triangulation of an intersection between the laser-line and the optical image of the laser-line, the three-dimensional coordinate points data used by the control subsystem to calculate predictive airflow through the workpiece with respect to the volume of the machined holes.

Abstract: Inspecting features of an object including measuring features of the master part that represents a desired nominal dimensions to obtain a preliminary set of dimensional data. The preliminary set of data becomes a master data set. The same master part is measured on a second machine to obtain another set of data on the master part. The two data sets are compared and correction data is generated representing differences between the different data sets for the same master part measured on different machines. Subsequent parts are then measured on the second machine to obtain measurement data that is corrected based on the correction data. The application of the correction information provides for the use of 5-axis machines within a desired measurement capability.
