Abstract: It is a system and a method for object measurement. The system may obtain an image of an object with a light bar acquired by an imaging device. The light bar may be formed by an optical sensor irradiating the object with a light beam. The system may obtain a measurement model. The measurement model may be configured to simulate a curved surface formed by the light beam. The system may determine position information of at least a portion of the object based at least in part on the image of the object with the light bar and the measurement model.

Abstract: A method for alignment of optical components of a projector (110) for illuminating at least one object (112) with at least one illumination pattern (114) comprising a plurality of illumination features. The projector (110) comprises at least one array of emitters (116). Each of the emitters is configured for generating at least one light beam. The projector (110) comprises at least one transfer device (118) configured for generating the illumination features from the light beams impinging on the transfer device (118).
