derive

Italian to English Tech/Engineering Mechanics / Mech Engineering
eliminare possibili derive in acquisizione

"Derive" in questo contesto significa qualcosa come "errori", "scostamenti dalla realtà"

il cliente ha preferito "errors"
Claudia Sorcini (asker) Aug 8, 2023:
Confermo che si parla di scansione: gli scostamenti (deviazioni) ci sono comunque, tra il dato nominale e quello acquisito, ma per "deriva" si intende uno scostamento non dato più da differenze di forma, ma dalla perdita del giusto sistema di riferimento, quindi suppongo che "drifts" vada bene

more context La misura dei marker è infatti un vero e proprio processo fotogrammetrico che “blocca” il volume della scena andando a garantire una maggiore accuratezza ed eliminare possibili derive in acquisizione.
Thomas Miles Aug 4, 2023:
'deviation' Close to the meaning of your 'scostamento' would be the word 'deviation', but I am reluctant to suggest this as a deviation is not an error in itself, and is indeed statistically measured rather than removed. It might work as 'erroneous deviation'.
philgoddard Aug 4, 2023:
Some of your other questions suggest that 'acquisizione' is about scanning, but you should provide the full context with each one.
philgoddard Aug 4, 2023:
We need the context for this one, please. What is it about, and what does it say before and after this?

eliminate (control?) possible drift in acquisition of scanned image

Continuous research on small-scale mechanical structures and systems has attracted strong demand for ultrafine deformation and strain measurements. Conventional optical microscope cannot meet such requirements owing to its lower spatial resolution. Therefore, high-resolution scanning electron microscope has become the preferred system for high spatial resolution imaging and measurements. However, scanning electron microscope usually is contaminated by *distortion and drift aberrations* which cause serious errors to precise imaging and measurements of tiny structures.

Thus, still using time-counting of different events in light, first research-based, then commercial 3D cameras started to become available, and rapidly found applications in audiovisual segmentation [9], RGB+depth fusion [10], 3D screens [11], people and object detection [12] and, of course, in human-machine interfaces [13], some of them reaching the general consumer market, being the best-known example the Microsoft Kinect [14]. These commercial units were in almost all cases amplitude-modulated cameras where the phase of the emitted light was compared with the received one in order to compare their phase difference to estimate distance.
