Abstract: Image processing includes obtaining image I[0,0] of a picture captured by an image capture means, in a state where light is irradiated to the picture from a light source at a reference position relative to a normal line of the picture, obtaining image I[?1,0] of the picture captured by an image capture means, in a state where the light is irradiated to the picture from the light source at a position inclined from the reference position at an angle ?1 in the first direction, obtaining image I[0, ?1] of the picture captured by an image capture means, in a state where the light is irradiated to the picture from the light source at a position inclined by an angle ?1 from the reference position in a second direction different from the first direction, creating a three-dimensional map of the picture, using a set of images I[0, ?1] and I[0, ?2], merging at least a part of each of image I[?1,0], image I[0,?1], and image I[0,?2] with respect to image I[0,0], and recording as two-dimensional image data the image subjec

Abstract: A ground surface estimation method includes: a continuous region recognizing step for recognizing, when a difference in altitude value between a representative point of one grid and a representative point of another adjacent grid out of the plurality of grids is equal to or less than a threshold, the one grid and the other adjacent grid as a continuous region that is a region where the one grid and the other adjacent grid are continuous; and a ground surface estimation step for estimating a continuous region having the largest number of grids among the continuous regions as a ground surface.

Abstract: The present invention provides a guide display device capable of recognizing a feature in a work area while distinguishing whether the feature is a moving body or not. In a guide display device of a crane, 3D maps are created for continuous frames; an altitude value for each grid in a 3D map that is created at time closest to the current time is obtained as a first altitude value; altitude values for respective corresponding grids in a predetermined number of 3D maps other than the 3D map that is created at time closest to the current time are obtained, and the average of the altitude values is calculated as a second altitude value; and it is determined that the feature is a moving body when the difference between the first altitude value and the second altitude value exceeds a predetermined threshold.

Abstract: Composite fine particles each having a nickel base core whose surface is coated with an oxide are effective for improving shrinkage upon firing and metal oxidation during binder burnout. The nickel base core has the formula: Ni(1-a-b)ZaZ′b wherein Z is Ag, Au, Co, Cu, Pd or a mixture of any, Z′ is Li, K, Na, B, P or a mixture of any, 0≦a≦0.4, 0≦b≦0.1 (weight proportion), and a+b>0, and the coating oxide is an oxide of Ag, Ba, Co, Cu, Ni, Sn, Ti, Zr, rare earth elements including Y, Pd or a mixture of any.
