摘要： 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.

摘要： 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.

摘要： 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.
