摘要： A system for measuring a distance to an object includes a camera positioned at a location and a signal generated by the camera that is reflective of a camera setting. A controller operably connected to the camera receives the signal and generates an accuracy signal based on the signal. The accuracy signal is reflective of a predicted accuracy of a distance measurement. An indicator operably connected to the controller provides an indication reflective of the accuracy signal. A method for measuring a distance to an object includes positioning a camera and generating a signal reflective of a predicted accuracy of a distance measurement. The method further includes providing an indication reflective of the signal, capturing one or more images of the object at the location, and calculating a distance to the object based on the one or more captured images of the object at the location.

摘要： A system for providing a two-position zoom-focus capability in a video inspection device comprising, in one embodiment, a focus lens cell and primary aperture attached to a set of fixed rails and connected to a zoom lens cell. In one embodiment, the focus lens cell is moveable into a first position along the rails through activation of a proximally located lens movement mechanism, and moveable into a second position through relaxation of a tensioned focus spring. In one embodiment, movement of the focus lens cell between first and second focus positions causes movement of the zoom lens cell and a secondary aperture between corresponding first and second zoom and aperture positions to provide unmagnified and magnified images of a target object.

摘要： A probe tip includes a plurality of light emitters and a control circuit that is coupled to the light emitters. The control circuit is configured to control a projection of a plurality of light patterns from the light emitters for performing a phase-shift analysis using a plurality of images of the light patterns that are projected onto a component being inspected. The control circuit controls the projection of the light patterns by receiving electrical energy from a drive circuit. At least one of the light emitters is identified for receiving a power input based at least in part on the electrical energy received from the drive circuit. The power input is transmitted to the identified light emitter, based at least in part on the electrical energy received from the drive circuit, to enable the activation of the identified light emitter.

摘要： A system for determining an object distance z includes a plurality of light emitters. A group of at least one of the plurality of light emitters includes an emitter group, and the pattern projected when one emitter group is emitting includes a fringe set. The light pattern of one fringe set exhibits a phase-shift relative to the light patterns of the other fringe sets, and the phase-shift varies as the distance from the origin of the plurality of fringe sets varies. The system further includes a processing unit that is configured to compute a ripple metric value associated with each of a plurality of possible z values. The processing unit is further configured to determine an approximated z value using the computed ripple metric values. A probe system is also provided. The probe system is configured to project a plurality of fringe sets from the probe onto an object. The light pattern of one fringe set exhibits a phase-shift relative to the light patterns of the other fringe sets, and the phase-shift varies as the distance from the origin of the plurality of fringe sets varies. The probe system is further configured to compute a ripple metric value associated with each of a plurality of possible z values, where z is an object distance. The probe system is also configured to determine an approximated z value using the computed ripple metric values. A method for determining an object distance z is also provided.

摘要： A method of determining the profile of a surface of an object is disclosed that does not require that the video inspection device be at a certain angle relative to the surface when an image of the surface is obtained (e.g., allows non-perpendicular captures of the image 30). The method determines a reference surface and a reference surface line. The reference surface line is then used to determine a surface contour line on the surface of the object. The profile is then determined by determining the distances between the reference surface and the surface contour line.
