Realistic virtual
environments

3D digitization, which allows transferring real environments to the computer, is a key step towards the digital twin, interventions or design modifications.

The use of photogrammetry and laser scanning enables massive environment capture, defined by georeferenced point clouds and images that provide realism through color. Given the volumetry of objects, data capture is performed from different angles, requiring subsequent registration and homogenization processing to obtain the realistic environment in which to navigate, incorporate data or take measurements.

Dogram has been recognized by the scientific community at various international conferences for the realism of its 3D digitizations. Since 2013, we have completed over 200 projects across diverse sectors including nuclear facilities, oil & gas, steel, construction, architecture, archaeology and museology.

Common needs
and challenges

Absence or outdated drawings of industrial installations.
Problems during construction of a design modification when encountering elements not considered in the design phase or methodological inconsistencies during on-site layout.
Access limitations restricted to shutdown periods, minimizing visit times to obtain real information about the environment where a new design must be implemented.
Absence of a common coordinate system for design and layout for contractors.
Delays in shutdown times during the replacement of high-value equipment in the plant.
In pre-task meetings or training, limitations in information transfer or planning due to lack of information or access restrictions to the work area.
Inability to quantify the deformation suffered by part of the installation or machine during different production phases (active/shutdown).
Difficulty in performing structural analysis or pathology studies due to environment complexity and/or access difficulty.

How can 3D digitization help you
with DOGRAM?

Through 3D digitization, updated drawings can be obtained, but we also advise our clients on implementing virtual tours, where they can obtain more detailed information about the plant or installation status.

We perform interference calculations of designs with existing plant elements, so the client can evaluate the design's adaptability to plant reality and make decisions prior to on-site execution.

We create a 3D digitization system that precisely links reality, engineering and assembly.

We adapt to shutdown periods and safety measures, making detailed joint plans with the client that allow us to obtain a detailed digital twin of areas of interest within available access times.

We establish a common coordinate system for reality and the digital twin, so that work between different contractors has a common language between the design phase and the execution phase of engineering projects.

We accompany the client in both 3D digitization and on-site layout of their designs. Virtual scene evaluation and simulations anticipate possible setbacks in task execution, allowing high process optimization.

The digital twin and virtual tours provide our clients with a collaborative and informative environment used to reduce plant visits, minimizing exposure to associated risks.

Verification of the connection of new equipment with existing components in the installation, through virtual analysis and diagnostic report.

We perform comparative analysis of digitization at different times and issue a report quantifying displacements, so the client can assess whether they fall within design expectations.
