中文摘要
针对工业测量、精密机械测试、运动追踪等领域对高动态目标的精密位置及姿态测量问题,抛弃传统的双目面阵以及三线阵立体视觉的形式,探索基于单维binning模式等效窄面阵相机实现高性能位置及姿态测量的新方法:通过单维binning模式将传统工业面阵相机转化为等效窄面阵,进而利用三个窄面阵相机通过角度交汇实现目标特征的准确定位和姿态求解。新方法旨在克服传统工业面阵相机采集速度有限、高帧频下感光度不足和数据量大的缺点,以及三线阵相机定制柱面镜、小通光量、抗干扰能力差、多目标能力弱的问题。主要研究内容包括窄面阵相机测量模型,非均匀图像特征提取,窄面阵相机组合分布模式,系统标定方法,测量系统搭建和测试验证等。本研究旨在为动态精密位置和姿态的视觉测量提供新思路和新方法,验证其可行性并评价其测量性能,具有重要的科学研究价值和工程应用潜力。
英文摘要
Aiming at the problem of precise position and orientation measurement of high dynamic targets in the fields of industrial measurement, precision mechanical testing, motion tracking, etc., a new high-performance method is explored based on equivalent narrow-area array cameras obtained by one-dimensional binning mode, in which the traditional binocular area array and three line array stereo vision are abandoned. Through the one-dimensional binning mode, a traditional industrial area array camera is converted into an equivalent narrow area array, and then three narrow area array cameras of angle intersections are used to realize the accurate position and orientation measurement of the target feature. The new method aims to overcome the shortcomings of traditional industrial area array camera, which has limited acquisition speed, insufficient sensitivity at high frame rate and large amount of data, as well as those of three line array cameras with cylindrical lens, which has small light flux, poor anti-interference ability, and weak multi-target capabilities. The main research contents include the measurement model of narrow-area array cameras, nonuniform image feature extraction, combined distribution mode, system calibration method, system construction and test verification. This study aims to provide new ideas and methods for the visual measurement of dynamic precise position and orientation, verifying its feasibility and evaluating its measurement performance, and have important scientific research value and engineering application potential.
