Extension of the Side Distance Measurement Aspect Ratio in the Measurement of a Slot or Bore Using a Commercial Laser Triangulation Sensor [PDF]

open access: yesSensors
We propose a new commercial laser triangulation sensor modification to enable the measurement of slots or bores side distance. The study showed the possibility of extending the sensor depth range for a slot or bore side distance measurement using a ...

Testing ToF Sensors for Use in Obstacle Detection Systems [PDF]

open access: yesProblemy Mechatroniki, 2022
ToF (Time of Flight) sensors have been gaining popularity in recent times as a cheap and accurate way to take distance measurements. They may prove to be a key component of obstacle detection systems in the near future.

Distance measures for embedded graphs [PDF]

open access: yesComputational Geometry, 2021
We introduce new distance measures for comparing straight-line embedded graphs based on the Fréchet distance and the weak Fréchet distance. These graph distances are defined using continuous mappings and thus take the combinatorial structure as well as the geometric embeddings of the graphs into account.

A vectorial tree distance measure [PDF]

open access: yesScientific Reports, 2021
Abstract A vectorial distance measure for trees is presented. Given two trees, we define a Tree-Alignment (T-Alignment). We T-align the trees from their centers outwards, starting from the root-branches, to make the next level as similar as possible.

Distance Measurements in UWB-Radio Localization Systems Corrected with a Feedforward Neural Network Model

open access: yesSensors, 2021
An ultra-wideband (UWB) localization system is an alternative in a GPS-denied environment. However, a distance measurement with UWB modules using a two-way communication protocol induces an orientation-dependent error.

Building 2D Model of Compound Eye Vision for Machine Learning

open access: yesMathematics, 2022
This paper presents a two-dimensional mathematical model of compound eye vision. Such a model is useful for solving navigation issues for autonomous mobile robots on the ground plane.

Invariants in problems of pattern recognition and control of states of complex objects

open access: yesВестник Дагестанского государственного технического университета: Технические науки, 2022
Objective. The aim of the study is to build emulators of the main sensors of a small spacecraft (SC).Method. The quality of recovery is determined by the standard deviation (RMS) of the data from the standards.

Absolute Distance Measurement Based on Self-Mixing Interferometry Using Compressed Sensing

open access: yesApplied Sciences, 2022
An absolute distance measurement sensor based on self-mixing interferometry (SMI) is suitable for application in aerospace due to its small size and light weight.

Distance Measures for Geometric Graphs

open access: yesComputational Geometry, 2023
A geometric graph is a combinatorial graph, endowed with a geometry that is inherited from its embedding in a Euclidean space. Formulation of a meaningful measure of (dis-)similarity in both the combinatorial and geometric structures of two such geometric graphs is a challenging problem in pattern recognition.
