Survey 13 – 3D Cloud Data – Architecture

Written By: Jean-Paul Cipria - Juil• 21•18

Voici un exemple d’utilisation d’une précision 3D maîtrisée [CIPRIA-2018] à l’aide d’un petit drone (100 € au lieu de 1500) avec photographie de très faible définition (1 Mpixels au lieu de 10), d’un PC, portable démonté, radiatorisé, de 4GO de RAM au lieu 16 .

Bref, que dalle ! Comme nous sommes habitués dans les entreprises Françaises où c’est pire …

My job is to integrate knowledges, understanding, methods in enterprise not essentially distributed to employees but dispatched to managers and directors.

I use to say : « ENGINEERS ARE SOLVING PROBLEMS YOU DIDN’T KNOW YOU HAD IN WAYS YOU DON’T UNDERSTAND. »

Survey 12 – 3D Cloud Datas

Written By: Jean-Paul Cipria - Avr• 28•18

How Can we Construct 3D Object by 39 Photographies ?

How do we take pictures ? Is it a surveyor and topograph measurements method ?

How do we gain this ?

3D Cloud Construct

2D Pictures ==> 3D Cloud Construct ==> 2D Mesh Links ==> 2D Surfaces Propagation

And just rotate 3D object !

We took a lot of photographies like aerial topography we use « stereo » display to match the unique points (Xi, Yi, Zi) via two photos with two points of view. What are the difficulties to use software to do this ? We don’t have calculations problems to solve but there is a lot of difficulties and time to spend ?

Survey 10 – Boresighting Processing – Simbleautage

Written By: Jean-Paul Cipria - Mar• 10•18

How do we break parallelism alignment between unreachable site and sighting ?

Boresighting Processing - Simbleautage-Visee-Tir

Boresighting Processing – Simbleautage – Shifted Target Path – Visée Décalée.

How do we focus on a satellite with one detector and send angle point of view to different sensors at different positions ? It is Parallax Calculation. You can control a digital servo motor to point another equipment on a same target. For example you made infra-red measurement distance, and gisement (referenced to Lambert Cartography North) from a mountain and you want to design the same target to a radar situated some meters lower.
