Adaptive illumination optimizing method adapting to complicated illumination scene

Abstract

The invention relates to an adaptive illumination optimizing method adapting to a complicated illumination scene. The adaptive illumination optimizing method adapting to the complicated illumination scene comprises the following steps: establishing a projector-camera system; simulating a complicated illumination environment, selecting measured objects with different surface reflectance to preventoverexposure of an interference light source, and controlling a CCD camera by a computer to obtain an original object image; projecting reference stripes generated by the computer to an object througha projector, selecting black and white stripes of which the phase difference is between 0 and 2 pi as the reference stripes which can distort after the strips are deeply modulated by a three-dimensional object, and acquiring the distorted strips by a camera; recovering the height information of the object; carrying out inverse operation on the original object image, and projecting an inverse image to the surface of the object by a projector and keeping pixel matching; running an iterative algorithm until an iterative termination criterion is met to ensure that an overexposure portion is partially repaired; calibrating a camera response curve; and fitting a high-dynamic range image, namely a HDR image, according to the camera response curve, and obtaining and outputting a final result.

Description

technical field [0001] The invention relates to a method for optimizing adaptive lighting, which belongs to the field of adaptive optics. Background technique [0002] In current machine vision systems, image quality is the decisive factor for system analysis and decision-making. Due to the complex environment, different surface reflectance of objects, uneven light source and other factors, the details of the image are usually lost. When there are different parts with high reflectivity and low reflectivity in the scene under test, increasing the exposure will oversaturate the part with high reflectivity; reducing the exposure will make the part with low reflectivity dark, thereby degrading the image quality and causing damage to the system Negative Effects.
