摘要： A method for generating a mask for use with a light measurement system that includes a light source for projecting light onto an object, and an imaging sensor for receiving light reflected from the object. The method includes determining a profile of the object to be inspected, and generating an electronic mask based on the determined object profile. The electronic mask has an electronic opening having a profile defined to substantially match the determined object profile as viewed from one of the light source and the imaging sensor.

摘要： An arrangement in which three-dimensional measurement sensors are calibrated using linear translation of three flat plates, one orthogonal to the path, one sloping vertically, one sloping horizontally. Sensors for which linear interpolation applies need only calibrate two surfaces of the sensor volume for complete calibration. Two flat surfaces are adequate for calibrating a volume if one surface is used twice.

摘要： Methods are provided for reducing the number of projected patterns required to make two- or three-dimensional surface measurements on a sub-class of surfaces comprising relatively smooth surfaces. By including apriori knowledge about the surface to be measured, pattern ambiguities can be resolved by processing rather than by additional projected patterns.

摘要： An apparatus with a common aperture and multiple image recording surfaces with individual filters and/or controlled shutters enables the implementation of several methods of 3-D measurement systems. The parallel nature of the device lends to short measurement times suitable for measuring moving objects. A similar apparatus may be constructed to project multiple images simultaneously or in rapid succession. Elimination of mechanical motion within the projectors and cameras of the prior art reduce the measurement time significantly. A new method of 3-D measurement employing a sweeping light plane and time encoded image recording uses the apparatus. An alternate method maintains a stationary projected light plane through which an object moves as it is measured in 3-D. Another method uses simultaneous projection of light patterns at different frequencies. Another method employs the time of flight of a light pulse and time encoded recording of the reflected energy.

摘要： An object is scanned first with a light plane from a variable-intensity light-plane projector, and the reflected light is used as signals to modify point by point the output of the projector in accordance with the intensity of the respective reflective-light signal. Thereupon the object is scanned a second time and the projector is instructed to apply less light than before to those points of the object from which a strong reflected-light signal was received during the first scan, and/or to apply more light to points from which a weak reflected-light signal was received during the first scan. In similar manner, a projected intensity encoded light volume is projected on an object and the reflected light is used as signals to point-by-point modify the output of the projector for subsequent projections.

摘要： A method for locating points on a surface in which the surface is irradiated selectively with an irradiating volume which has a varying intensity that defines a first pattern. After irradiating the surface with the first pattern, the surface is irradiated similarly with volumes having varying intensities defining a second or more patterns. Both of these patterns are applied to a point to be located on the surface. The radiation impinging on the surface is recorded by a camera which forms images of the patterns. The images are scanned to find the intensities of the point in the two or more patterns. More than one pattern may be simultaneously irradiated, using different frequencies to distinquish the data. The location of the point on the surface is dependent on a predetermined ratio or difference of the intensities of the point in the two or more patterns. The patterns may be linear, sinusoidal, smooth, non-smooth and/or two dimensional functions ultimately producing a single valued ratio or difference result.

摘要： A method, apparatus, and computer instructions for testing software programs running on a data processing system. Text is translated from the source language to the target language to form translated text in response to a user input, containing the text in a source language. The text is entered through a computer interface in the data processing system. The translated text is inserted into a user interface of the software program to be tested to form inserted, translated text. The software program is written using the target language. A determination is made as to whether the software program functions correctly using the inserted, translated text.
