Abstract: The present invention relates to a method and system for quantitatively evaluating surface roughness of an organic pore of kerogen in shale. The method includes: making a shale sample; applying a circle of silver-painted conductive tape on the edge of the shale sample to obtain a processed sample; conducting image scanning on the processed sample to obtain a scanned image; determining a kerogen area according to the scanned image; determining an organic pore area according to the kerogen area; carrying out gridding treatment on the organic pore area to obtain multiple grid cells; adopting double integral calculation on each of the grid cells to obtain the areas of the multiple grid cells; summing each of the areas to obtain the surface area of the organic pore; and evaluating surface roughness of the organic pore according to the surface area of the pore.

Abstract: A machine vision detection method includes receiving a three-dimensional image from a line laser, converting the three-dimensional image into a two-dimensional grayscale image, obtaining a boundary of a first component and a boundary of a second component in the two-dimensional grayscale image, determining N perpendicular lines between the boundary of the first component and the boundary of the second component, and calculating an average length of the N perpendicular lines as a gap between the first component and the second component. The three-dimensional image includes at least a portion of the boundary of the first component, at least a portion of the boundary of the second component, and a welding spot located on the boundary of the first or second component. N is a positive integer.

Abstract: The present application relates to a method, apparatus and system for inspecting a cell crush, a computer device, a storage medium, and a computer program product. The method may include: acquiring images of a flowing cell assembly by a high-speed image acquisition device; extracting image features from the images of the cell assembly; performing similarity matching between the image features and a preset crush model to obtain a similarity matching result; and obtaining a cell crush inspection result based on the similarity matching result.

Abstract: A detection apparatus includes a support, at least one driving apparatus provided on the support, and a first movable module. The at least one driving apparatus includes a first driving apparatus, and the first driving apparatus is connected to the first movable module. The first movable module is provided with a first sliding assembly, and a first camera connected to the first sliding assembly. The first driving apparatus is configured to control the first sliding assembly to move in a first direction to drive the first camera to move close to or away from a material to be photographed. An included angle between the first direction and a vertical direction is less than or equal to a preset angle threshold.

Abstract: A spur dike type fishway inlet includes an upstream flow block wall, an extra water supply nozzle, and an artificial fish reef. The upstream flow block wall is arranged upstream of a fishway inlet; the starting end of the upstream flow block wall is connected with the upstream side wall of the fishway inlet through a connecting shaft and a hydraulic strut. The extra water supply nozzle is installed in the fishway inlet and is connected to the upstream of a power station through a pipeline to directly supply water to a high water head. The artificial reef is set up within the shielding range of the upstream flow block wall.
