摘要： A laser scanner and a system with a laser scanner for measuring an environment. The laser scanner includes an optical distance measuring device, a support, a beam steering unit rotatably fixed to the support which rotates around a beam axis of rotation. The beam steering unit includes a mirrored surface which deflects radiation used in the optical distance measurement and an angle encoder for recording angle data. The optical distance measurement is performed by a progressive rotation of the beam steering unit about the beam axis of rotation and the continuous emission of a distance measurement radiation, the emission being made through an outlet area arranged in the direction of the mirrored surface on the support, the receiving optics for receiving radiation are arranged on the support, and wherein the outlet area has a lateral offset with respect to the optical axis of the receiving optics.

摘要： A mobile security system includes a first camera, a second camera, and a controller. The first and second cameras capture first and second images at a first time and include first and second object images of an object, respectively. The controller: obtains a camera distance between the first and second cameras, receives the first and second images from the first and second cameras, retrieves the first and second object images in the first and second images, respectively; determines first and second object image sizes of the object in the first and second object images, respectively; calculates a first object distance between the first camera and the object using the camera distance and the first and second object image sizes; determines whether the first object distance satisfies criteria of a security policy; and if so, apply a security action associated with the security policy.

摘要： An apparatus and a method performing work free from variations among a plurality of work heads having individual differences. A working apparatus includes a number n (a natural number 2 or greater) of work heads, a stage retaining a work object, drive devices moving the stage and the work heads relative to each other in three directions, a work amount measurement device measuring a work amount of each work head, and a control device, wherein the first-direction drive device enables the number n of work heads to be independently moved in a first direction, and the second-direction drive device includes a second-direction main drive device moving the number n of work heads simultaneously in a second direction, and a second-direction auxiliary drive device moving n−1 work heads among the number n of work heads independently in the second direction. A working method is carried out using the working apparatus.

摘要： A first estimating unit estimates at least one of a position and an attitude of a predetermined object on the basis of an image of a periphery of the object, the image being obtained from an imaging device, and generates an estimation result not including an accumulated error. A second estimating unit estimates at least one of the position and the attitude of the object on the basis of the image, and generates an estimation result including an accumulated error. A correcting unit compares the estimation result of the first estimating unit and the estimation result of the second estimating unit with each other, and corrects, on the basis of a result of the comparison, a subsequent estimation result of the second estimating unit, the subsequent estimation result being subsequent to the estimation result of the second estimating unit which estimation result is used for the comparison. An App executing unit performs predetermined data processing on the basis of the estimation result of the second estimating unit which estimation result is corrected by the correcting unit.
