摘要： A detection system based on modulation of line structured laser image of glass includes a processing section, a control system, and roller conveying mechanisms. Detection mechanism provided over entrance of the processing section includes shell and camera with laser which emits beam on the surface of the glass in the gap between sliding rollers. Focal plane of the camera corresponds to the beam irradiation surface, and signal output terminal of the camera is connected with the control system in such a way that when glass passes the detection area, laser irradiates the glass surface and the line structured laser is modulated based on the glass to form laser modulation image with distribution of light and shade, staggered movement direction, or distorted laser lines. The camera transmits the captured glass information and parameters to the control system.

摘要： A detecting method and an optical apparatus using the detecting method are provided. The optical apparatus includes a structured light generation unit and a sense judging unit. When a structured light from the structured light generation unit is projected on a test surface, a test pattern and a test light spot are shown on the test surface. The sense judging unit judges whether the test surface is flat according to a deformation amount of the sensed test pattern, and acquires a distance between the test surface and the optical apparatus according to an area of the sensed test light spot. The detecting method judges whether a test surface is flat and detect a distance of the test surface. Since the structured light is used to detect the distance and the flatness of the test surface, the measuring complexity is reduced.

摘要： An inherent pattern image (100, 100F) of a test object (10) is recorded when the test object is illuminated with uniform illumination light, and a projection pattern image (200, 200F) is recorded when the test object is illuminated with a spatially modulated projection pattern. A planar displacement vector field (110, 110F) is calculated from the inherent pattern image, and a shape (210, 210F) is calculated from the projection pattern image. An image of the first type is recorded at time (tT), and images of the second type are recorded at times (tT−; tT+) before and after the time (tT). A representation of the test object at the test time (tT) is estimated by averaging. A spatial displacement vector field (300) is based on the calculated representation of the test object of the first image type and the representation of the test object estimated from the images of the second type.

摘要： A method of analysing breathing data representing a shape of the trunk of a subject 104 as a function of time to monitor and/or analyse the subject's breathing pattern. The data is measured and processed into a data array relating to a 2-dimensional grid having grid points, a position in space of the shape at each grid point and points of time. The method includes the steps of mapping the data array onto a 2-dimensional array, decomposing the 2-dimensional array and forming a signature of the subject 104 from the decomposed 2-dimensional array representing a motion pattern.
