Lane detection algorithm based on temporal–spatial information matching and fusion

open access: yesCAAI Transactions on Intelligence Technology, 2019
Given the problems of less single-image information and poor anti-interference ability, a lane detection algorithm based on temporal-spatial information matching and fusion by reverse perspective transformation is proposed in this study.

Mosaicing of multiplanar regions through autonomous navigation of off-the-shelf quadcopter

open access: yesIET Cyber-systems and Robotics, 2019
The real world is made up of multiplanar and curved surfaces. Imaging such surfaces with an orthographic view using a handheld camera is tiring if the scene encompasses a view larger than the camera field of view.

Sensor for Distance Measurement Using Pixel Grey-Level Information

open access: yesSensors, 2009
An alternative method for distance measurement is presented, based on a radiometric approach to the image formation process. The proposed methodology uses images from an infrared emitting diode (IRED) to estimate the distance between the camera and the ...

Direct comparison of herpetofaunal camera, pitfall, and funnel trapping in the upland habitats of Florida, USA

open access: yesWildlife Society Bulletin
Determining the best method to survey species of interest is critical for successful field research projects. When sampling herpetofauna, pitfall and funnel trapping allow a researcher to examine multiple individuals but require considerable field effort

Web service with machine learning model for airspace monitoring

open access: yesВестник Дагестанского государственного технического университета: Технические науки
Objective. The goal is to develop a web service for detecting aerial objects that detects a flying object, highlights it in an image and classifies it as a threat, since modern aerial object detection systems do not always cope with the task of detecting

Experimental Demonstration of 32‐PAM Optical Camera Communication Using a Low Cost and a High Cost Camera

open access: yesIET Optoelectronics
This work demonstrates experimentally the feasibility of using up to 32‐PAM in rolling shutter based optical camera communication (OCC). Two different cameras have been used for OCC performance comparison, namely, a low‐cost Pi Camera V2.1 and a higher ...
