  • Patent number: 10924729
    Abstract: The present invention provides a method and a device for calibration applied to the field of image processing. The method includes: acquiring a common two-dimensional image and an infrared image of a calibration object, wherein the calibration object carries a first pattern; calculating coordinates of the first pattern in the common two-dimensional image, acquiring coordinates of the first pattern in a global coordinate system, and calculating intrinsic parameters of a first camera device capturing the common two-dimensional image; and calculating coordinates of the first pattern in the infrared image, acquiring the coordinates of the first pattern in the global coordinate system, and calculating intrinsic parameters of a second camera device capturing the infrared image. The method for calibration is capable of enhancing calibration efficiency by a simple calibration method when calibrating a depth camera device.

  • Patent number: 10872439
    Abstract: The present invention provides a method and a device for verification applied to the field of image processing. The method includes: acquiring a common two-dimensional image, an infrared image and a depth map of a calibration object, wherein the calibration object carries a first pattern; calculating coordinates of an image formed on the infrared image by the first pattern, acquiring a depth value of the first pattern according to the depth map, and calculating a position of a projection formed on the common two-dimensional image by a three-dimensional point cloud corresponding to the image formed on the infrared image by the first pattern, and calculating a distance between an image and the projection formed on the common two-dimensional image by the first pattern. The method and device for verification provided by the present invention can verify a calibration parameter obtained after calibration performed by a depth camera device, enhancing calibration accuracy.

  • Patent number: 10253329
    Abstract: The present invention relates to compositions and methods for identifying and using new germplasm providing aphid resistant in soybean plants, particularly for use in breeding soybean plant lines and cultivars representing specific set(s) of germplasm. In particular, aphid resistant soybean plants comprising new sources of germplasm and stacked germplasm/genes conferring enhanced aphid resistance are provided. These enhanced aphid resistant plants find use in breeding soybean plant lines (cultivars) including lines having superior aphid resistance. Further, the inventions relate to providing new aphid resistant germplasm identified by markers associated with plants having decreased damage from aphid feeding, as well as plants having enhanced tolerance to aphid infestation.
