摘要： a plurality of sensing units are buried at suitable intervals in an area of ground or a snow accumulation section to be observed. Each of the sensing units includes a gyro-sensor (102) for, when external force acts on it as a result of the displacement of the ground or the snow accumulation section, sensing impulsive acceleration from the magnitude and direction of the displacement and the inclination of the sensing unit itself, and a transmission section (108) for transmitting the sense data by radio. A base station acquires the sense data transferred from the sensing units, processes the sense data for each measuring point in real time, determines the movement of the ground and/or the snow accumulation section, and judges a state of the ground and/or the snow accumulation section on the basis of the movement.

摘要： In a contact lens visual inspection method and apparatus, a contact lens insertion portion (33a) of a container (33) is first imaged by an image pickup device and then an area which locates on the container and is unnecessary for the visual inspection of a contact lens is extracted from the image of the contact lens insertion portion to form a mask image. Thereafter, a system containing the contact lens insertion portion (33a) of the container, the preservation liquid filled in the contact lens insertion portion and the contact lens placed in the contact lens insertion portion is imaged as an inspection object by the imaging device to obtain an inspection object image, the inspection object image is overlapped with the mask image, and the mask image is subtracted from the inspection object image to set as a visual inspection area the area corresponding to a subtracting image obtained by said subtracting step. The defects of the contact lens such as soil, foreign matters, scratch, breakage, peripheral damage, etc. detected for the visual inspection area.

摘要： The present invention provides a method and apparatus of inspecting a surface of an object article capable of precisely detecting stains or miniature defects present in the object surface. Specifically, the invention provides a method of inspecting surface irregularity of an object article having a surface of uniform or regular brightness, which comprises the steps of: gaining brightness informations for a plurality of two-dimensionally distributed pixels by taking a picture of the article surface; finding stains on the article surface in response to each information obtained in the brightness information gaining step to produce a first output; finding miniature defects smaller in size than a unit pixel in response to each information obtained in the brightness information gaining step to generate a second output; switching the first output and the second output into appropriate electrical signals in a controlled manner; and displaying the switched electrical signals on a display in a viewable condition.
