Research on road vehicle and lane line detection based on improved YOLOv4-tiny algorithm [PDF]

SHS Web of Conferences, 2022
In order to improve the speed of road vehicle and lane line detection, a road vehicle and lane line detection method with improved YOLOv4-tiny algorithm is proposed by using K-means++ clustering algorithm instead of the original K-means algorithm.

A change-detection algorithm for short-circuit fault detection in closed-loop AC drives [PDF]

, 2013
This paper deals with an on-line method for turn-to-turn short-circuit fault detection in low-voltage permanent-magnet synchronous machine drives. Due to the closed-loop control, the fault effects are reflected in the voltage.

Extrinsic Calibration of 2D Laser Rangefinders Using an Existing Cuboid-Shaped Corridor as the Reference

Sensors, 2018
Laser rangefinders (LRFs) are widely used in autonomous systems for indoor positioning and mobile mapping through the simultaneous localization and mapping (SLAM) approach. The extrinsic parameters of multiple LRFs need to be determined, and they are one

Line Detection Using Radon Transform [PDF]

Engineering and Technology Journal, 2010
To extract features from digital images, it is useful to be able to find simpleshapes (straight lines, circles, ellipses, etc.).In order to achieve this goal, one can be able to detect a group of pixels that are ona straight line or a smooth curve.

On-linesurface defect detection for steel rails based on multi-line lasers

工程科学学报, 2021
Multi-line lasers were applied to the on-line defect detection for steel rails instead of single-line laser,which solved the problem of "pseudo defects" due to the vibration of rails under the mode of single-line laser.
