摘要： A method and device are provided for receiving data about lighting condition of an environment as captured by a sensor of a moving autonomous device in a first position. Data is also received about lighting condition of the environment in at least a second position. The lighting conditions of the environment is then analyzed for each position and a lighting model is generated based on lighting of the environment in the different positions for the environment.

The method for training a machine-learning model to generate images of biological samples may include obtaining a plurality of training images comprising a training image of a first type, and a training image of a second type. The method may also include generating, based on the training image of the first type, a plurality of wavelet coefficients using the machine-learning model; generating, based on the plurality of wavelet coefficients, a synthetic image of the second type; comparing the synthetic image of the second type with the training image of the second type; and updating the machine-learning model based on the comparison.

摘要： Methods and apparatus for specular surface mapping in which a camera detects reflections of a light source from a specular surface. The detected light sources may be projected onto a celestial sphere as virtual point sources. True positive observations should be tightly clustered on the celestial sphere; thus, false positives may be identified and removed. Specular surface information may then be determined from clusters of the virtual point sources on the celestial sphere. The clusters of virtual point sources on the celestial sphere may be identified and used to identify a surface as a specular surface. The clusters may also be used to extract other information regarding the specular surface, including but not limited to distance to and extent of the specular surface.

摘要： A method for inspecting nominally identical workpieces with manufacturing tolerances involves feeding a workpiece to an inspection device; applying a simultaneous translatory and rotational movement to the workpiece via the inspection device while illuminating the workpiece; repeatedly taking camera images of the workpiece during the simultaneous translatory and rotational movement as the workpiece moves across a camera window, the camera images consisting of pixels; setting workpiece parameters based on size and shape of the workpiece; assembling a composite image from the camera images based on the workpiece parameters; determining numerical brightness scores of the workpiece, comparing the determined numerical brightness scores with known numerical brightness scores; assigning a discrepancy score; setting a discrepancy score threshold; determining that the workpiece passes inspection when the discrepancy score is below the discrepancy score threshold; and that the workpiece fails the inspection when the discrepancy score is above the discrepancy score threshold.
