The deflection that can reflect the vertical stiffness of a bridge plays an important role in the
structural evaluation and health monitoring of bridges. In the past 20 years, the bridge …

This paper proposes a novel method for six degrees of freedom pose estimation of objects
for the application of robot arm pick and place. It is based on the use of a stereo vision …

This paper presents a 3D distance measurement accuracy improvement for stereo vision
systems using optimization methods A Stereo Vision system is developed and tested to …

Background Camera calibration is an essential step for the optical measurement method
used in the experimental mechanics. Most plumb line methods focus on solving lens …

Perspective and optical (lens) distortions are aberrations of very different nature that can
simultaneously affect an image. Perspective distortion is caused by the position of the …

摘要现有双目相机标定的方法是通过矩阵变换求得各个相机间的旋转平移关系,
再通过优化求得最终参数. 非线性优化步骤多, 相机内外参数与镜头畸变存在耦合 …

Multi-modal sensors such as hyperspectral line-scan and frame cameras can be
incorporated into a single camera system, enabling individual sensor limitations to be …

Spacecraft pose estimation is an important technology to maintain or change the spacecraft
orientation in space. For spacecraft pose estimation, when two spacecraft are relatively …

Traditional vision is focused on the perception of visible light but limits us to only detecting
surface features. Near-infrared light can penetrate certain materials, so to capture this light …
