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.

Contour sensor incorporating MEMS mirrors

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.

Remote inspection device

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.

An integrated solid state device for viewing and manipulating objects located in remote sites and locations which includes a flexible cable having a camera on one end and a viewer on an opposite end. The camera captures images near the end of the flexible cable and converts the images into a video signal that is transferred through wires that extend through the length of the flexible cable. The video signals are received by the viewer and converted into a displayed image. A variety of removable article manipulators can be attached to the distal end of the flexible cable and used to manipulate, capture and retrieve articles and objects near the distal end of the flexible cable.

Display housing for remote inspection device

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.

Modular non-contact measurement device for quickly and accurately obtaining dimensional measurement data

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.
