Abstract: In an example embodiment, the controller is designed with a single current sensing circuit that is able to measure the current on multiple LED channels, eliminating the need for each LED channel to have its own current sensing circuit. The current sensing circuit may further be utilized with a control unit, which has an LED control model selection multiplexor (MUX) that switches between real-time closed-loop control and open-loop control.

Abstract: A feature inspection lighting system includes an outer cover having a mounting structure at a first end thereof and defining an outer periphery at a second end thereof. The cover includes an inner surface between the first end and the second end. The inner surface has raised surfaces defined thereon. A plurality of light sources is coupled to the raised surfaces of the inner surface of the cover, and cables to provide electrical power to the light sources is routed between the raised surfaces of the outer cover. The outer periphery of the cover may have a cutout defined therein through which all or part of an object to be inspected can pass.

Abstract: The present disclosure relates to a method, devices, and storage medium for training neural networks based on memory scores. The said method comprises: establishing the memory scores of a plurality of first-sample images in the library, from their training ages and training indicators, and a preset discount rate; determining a plurality of second-sample images from these memory scores and a preset first count, and using them to establish the first training set; training the neural network by using the first training set, with the said neural network is used for defect detection. The neural network training method in the disclosed embodiment reduces the size of the training set and shortens the time to converge, thereby improving training efficiency.

Abstract: A defect detection device includes an image capturing component for capturing one or more images of an object to be inspected; a motion component configured to grasp or manipulate the object or the image capturing component; and a computing device configured to perform a defect detection method, including determining a plurality of first image capturing poses of the object to be inspected; determining a first defect probability for each particular first image capturing pose; establishing a probability matrix based on the first defect probabilities; subdividing the probability matrix into a plurality of submatrices according to preset dimensions for each submatrix; determining a second defect probability for each of the plurality of submatrices; setting a maximum value of the second defect probabilities as a third defect probability of the object to be inspected; and comparing the third defect probability to a threshold to determine whether the object is defective.
