3D Reconstruction with Uncalibrated Cameras Using the Six-Line Conic Variety [PDF]
, 2008 We present new algorithms for the recovery of the Euclidean structure from a projective calibration of a set of cameras with square pixels but otherwise arbitrarily varying intrinsic and extrinsic parameters.

Robust 3D-Mapping with Time-of-Flight Cameras [PDF]
, 2009 Time-of-Flight cameras constitute a smart and fast technology for 3D perception but lack in measurement precision and robustness. We present a comprehensive approach for 3D environment mapping based on this technology.

An improved YOLOv3‐tiny algorithm for vehicle detection in natural scenes
IET Cyber-systems and Robotics, 2021 YOLO (You Only Look Once), as a target detection algorithm with good speed and precision, is widely used in the industry. In the process of driving, the vehicle image captured by the driving camera is detected and it extracts the license plate and the ...

Efficient generic calibration method for general cameras with single centre of projection [PDF]
, 2007 Generic camera calibration is a non-parametric calibration technique that is applicable to any type of vision sensor. However, the standard generic calibration method was developed with the goal of generality and it is therefore sub-optimal for the ...

Measuring straightness errors of slender shafts based on coded references and geometric constraints
The Journal of Engineering, 2020 The coded references and geometric constraints based method is suggested to solve the inconsistency problem of measurement range and accuracy for slender shafts. First, a slender shaft is divided into segments.
