High-resolution industrial imaging equipment and imaging method for curved surface

Abstract

The invention provides high-resolution industrial imaging equipment and an imaging method for a curved surface. The equipment comprises a computer, a curved-surface scanning motion subsystem, a scanning position sensor, an optical lens and a field curvature self-adaptive linear array detector module, wherein the curved-surface scanning motion subsystem is used for realizing relative motion of a curved surface relative to an optical lens according to a scanning path planned by a computer, and the scanning position sensor is used for detecting a current scanning position of the curved surface ofthe curved-surface scanning motion subsystem in real time; the computer calculates a curved image surface passing through the optical lens according to the real-time scanning position of the curved surface of the curved-surface scanning motion subsystem to obtain the position, matched with the curved image surface, of each linear array detector in the field curvature self-adaptive linear array detector module; and the field curvature self-adaptive linear array detector module controls each linear array detector to move to a position coinciding with the curved image surface, so high-resolutionimaging is realized. According to the invention, high-efficiency and high-resolution imaging of the curved surface can be realized.
