    Abstract: The present disclosure relates to an inspection apparatus, an inspection method, and a program that acquire inspection results with increased accuracy. In one example the inspection of lawn vegetation is provided. The inspection apparatus calculates a vegetation index for inspecting the vegetation of a lawn by cancelling a grain-dependent component from an image of the lawn. The inspection apparatus also cancels an imaging-direction-dependent component from the image using two images taken with azimuth angles of imaging directions at the time of taking images in directions opposite to each other. Further, the inspection apparatus cancels an angle-dependent component from the image in accordance with a shining direction of light shone on the lawn using two images taken with azimuth angles of the shining direction of light shone on the lawn at the time of taking images in directions opposite to each other.

  • Patent number: 9715721
    Abstract: Focus detection is to determine whether an image is in focus or not. Focus detection is able to be used for improving camera autofocus performance. Focus detection by using only one feature does not provide enough reliability to distinguish in-focus and slightly out-of-focus images. A focus detection algorithm of combining multiple features used to evaluate sharpness is described herein. A large image data set with in-focus and out-of-focus images is used to develop the focus detector for separating the in-focus images from out-of-focus images. Many features such as iterative blur estimation, FFT linearity, edge percentage, wavelet energy ratio, improved wavelet energy ratio, Chebyshev moment ratio and chromatic aberration features are able to be used to evaluate sharpness and determine big blur images.

  • Patent number: 9657735
    Abstract: The objective of the present invention is to reduce a meshing seal line length and further reduce a blowhole area. A compression side blowhole B2 is generated in a region surrounded by a male rotor side blowhole contour R1, a female rotor side blowhole contour R2, and a lower cusp line k2. By configuring a female rotor side blowhole contour R3 with a curve including at least two arcs C1 and C2, an area of the compression side blowhole B2 may be reduced. At a connection point between arcs, by making tangents of the arcs on both sides across the connection point to be the same gradient, the arcs may be smoothly connected.
