Patent number: 9013711Abstract: A structured light sensor system for measuring contour of a surface includes a control module that coordinates control of both a projection system and an imaging system to operate the structured light sensor system in three different modes. The imaging system is configured to selectively capture an image of light reflected off of the surface. In point mode, the imaging system is on for a first period during which the projection system projects a point of light onto the surface. In line mode, the imaging system is on for a second period during which the projection system projects onto the surface a first plurality of points of light forming a line of light. In area mode, the imaging system is on for a third period during which the projection system projects onto the surface a second plurality of points of light forming a plurality of lines of light.Type: GrantFiled: August 8, 2011Date of Patent: April 21, 2015Assignee: Perceptron, Inc.Inventors: Shyam P. Keshavmurthy, Chengchih Lin, Alfred A. Pease, Richard A. Krakowski

Patent number: 8218074Abstract: A remote inspection device is provided for inspecting visually obscured locations. The device is generally comprised of a imager housing and a display housing disposed on opposite ends of a modular, flexible cable. An imaging device is embedded in the end of the cylindrical imager housing, such that the imaging device is able to capture an image of a viewing area proximate to the distal end of the flexible cable. One or more light sources also protrude from the outwardly facing end of the cylindrical imager housing along a perimeter of the imaging device such that the imaging device is recessed between the light sources. A display housing is coupled to the other end of the flexible cable and configured to be grasped by a user of the device. A display device supported by the display housing receives a video signal from the imaging device and converts the video signal to a video image.Type: GrantFiled: July 29, 2009Date of Patent: July 10, 2012Assignee: Perceptron, Inc.Inventors: Alfred A.

Patent number: 8014002Abstract: A structured light sensor system for measuring contour of a surface includes an imaging lens system, an image capturing device, a first set of micro electromechanical system (MEMS) mirrors, and a control module. The imaging lens system focuses light reflected from the surface, wherein the imaging lens system has a corresponding lens plane. The image capturing device captures the focused light and generates data corresponding to the captured light, wherein the image capturing device has a corresponding image plane that is not parallel to the lens plane. The first set of MEMS mirrors direct the focused light to the image capturing device. The control module receives the data, determines a quality of focus of the captured light based on the received data, and controls the first set of MEMS mirrors based on the quality of focus to maintain a Scheimpflug tilt condition between the lens plane and the image plane.Type: GrantFiled: April 1, 2009Date of Patent: September 6, 2011Assignee: Perceptron, Inc.Inventors: Shyam P.

Publication number: 20070185379Abstract: A remote inspection device includes a digital imager housing having a digital imaging device in communication with a digital video signal conversion device serializing the digital video signal. A digital display housing has a digital display in communication with a digital video signal re-conversion device de-serializing the digital video signal. A push stick housing is configured to be grasped by a user. A flexible cable interconnects the digital imager housing with the push stick housing, thereby rendering a position of the digital imager housing responsive to user manipulation of the push stick housing. The flexible cable also serves as a transmission medium transmitting the serialized digital video signal at least from the digital video signal conversion device to the push stick housing.Type: ApplicationFiled: December 22, 2006Publication date: August 9, 2007Inventors: Tye Newman, Al Boehnlein, Paul Eckhoff, Alfred Pease

Patent number: 6858858Abstract: A hand-held or tool integrated measurement device is provided for quickly and accurately performing non-contact measurements of dimensions and/or angles associated with various objects in a home or commercial work area. The measurement device generally includes at least one user input element, a non-contact sensor, an image processor and a display element packaged in a portable housing assembly. In operation, a user initiates the measurement by activating the user input element associated with the measurement device. The non-contact sensor receives a trigger signal from the user input element and is operative to collect image data representative of at least a portion of the surface of a measured object. The image processor in turn receives the image data from the non-contact sensor and is operative to convert the image data into measurement data for the measured object. The display element is operable to visually display the measurement data to the user.Type: GrantFiled: May 27, 2003Date of Patent: February 22, 2005Assignee: Perceptron, Inc.Inventor: Alfred A. Pease

Patent number: 6858857Abstract: A modular measurement device is provided for quickly and accurately performing non-contact measurements of various objects at different locations within a commercial or residential work area. The modular measurement device generally includes a laser base that is operable to project light onto a measured object; and a portable measurement module adapted to receive light reflected from a surface of the measured object and operable to determine dimensional measurement data for the measured object, where the portable measurement module is configured to releasably couple to the laser base. The operational components of the measurement device are partitioned between the portable measurement module and the laser base. In this way, a single portable measurement module having more expensive operational components may be used with different, less expensive laser bases, where each laser base may be adapted for a different application.Type: GrantFiled: May 5, 2003Date of Patent: February 22, 2005Assignee: Perceptron, Inc.Inventors: Alfred A.
