阅读说明：本技术 图像获取方法及系统 (Image acquisition method and system ) 是由 王星泽 何良雨 舒远 于 2018-12-19 设计创作，主要内容包括：一种图像获取方法,该方法包括：投射模块初始光栅条纹到目标物体的被测面(201),成像模块接收所述初始光栅条纹经过所述被侧面反射后的初始调制光栅条纹(202)；成像模块根据所述初始调制光栅条纹,确定出所述被测面的参考三维图像(203)；若所述参考三维图像的图像质量低于预设图像质量阈值,则根据所述参考三维图像确定出目标光栅条纹(204)；分区域自适应地控制微型LED阵列,实现对光栅条纹的精确调整,并将所述目标光栅条纹投射到所述被测面(205)；接收所述目标光栅条纹经过所述被测面反射后的目标调制光栅条纹(206)；根据所述目标调制光栅条纹,确定出所述被测面的目标三维图像(207)。该方法突出检测场景中的黑暗区域,减弱饱和区域,可提升对目标物体的被测面的图像获取时的准确性。(An image acquisition method, the method comprising: projecting module initial grating stripes to a measured surface (201) of a target object, and receiving initial modulation grating stripes (202) of the initial grating stripes after being reflected by the side surface by an imaging module; the imaging module determines a reference three-dimensional image (203) of the measured surface according to the initial modulation grating stripes; if the image quality of the reference three-dimensional image is lower than a preset image quality threshold, determining a target grating stripe (204) according to the reference three-dimensional image; the micro LED array is controlled in a regional self-adaptive mode, the grating stripes are accurately adjusted, and the target grating stripes are projected to the measured surface (205); receiving target modulation grating stripes (206) of the target grating stripes after the target grating stripes are reflected by the measured surface; and determining a target three-dimensional image (207) of the detected surface according to the target modulation grating stripes. The method highlights dark areas in the detection scene, weakens saturated areas, and can improve the accuracy of image acquisition of the detected surface of the target object.)
