1 Introduction
User Manual 6
This document describes the detailed operation of the Eyesmap Tablet for each
individual module and feature. It intends to be a guide explaining the use of the
different modules, for you to get the best out of your Eyesmap tablet. This manual will
help you how best to capture 3D data in the field in order to obtain the best final results
possible.
1.1. EyesMap Tablet
EyesMap is a High Capacity Tablet PC that allows measurement, 3D modelling and
documentation of the environment around us. This measurement device, with its two
integrated and calibrated HR cameras, is based on photogrammetry, and in addition
relies on other sensors to capture detailed 3D models of the environment and complex
3D geometric objects quickly and conveniently.
The results obtained by this tablet are 3D models of both small objects, as well as mid-
sized and big objects containing millions of points. It allows real-time measurement of
coordinates, distances and surfaces and generation of real orthophotos. All these
results can be positioned geographically in real time thanks to the integrated GPS.
High Processing Capacity
Simple and intuitive Interface
High mobility due to the portability
and light weight of the device
Attractive and ergonomic design
High connectivity through USB,
Micro SD and HDMI.
Speed
High Resolution 3D models
generated.
Integrated inertal system
Integrated GPS
High speed data communication
through WLAN and 3G.

1.2. How does EyesMap work?
The measurement modules and the 3D Photo modelling are based on
photogrammetric techniques. Photogrammetry is a technique to determine the
geometric properties of an object from photographic images. By orienting the different
captured images of an object we can create stereoscopic view, allowing the generation
of 3-dimensional information.
In the following image the position of the cameras is displayed.
For 3D modelling indoors, the use of the depth sensor is recommended. This sensor is
projector of infrared points combined with a CMOS sensor allowing to capture the
environment in 3D in any light conditions. The useful detection range of the depth
sensor is up to 4 meter.
In the following image the position of the depth sensor is displayed.
The obtained 3D results can be geo-referenced real-time through the integrated GPS
at a best accuracy of 0.6m. If higher absolute precision is required, the –at least 10
minutes- collected data can be post-processed up to a best accuracy of 0.10m.
The integrated inertial system comprises a gyroscope, an accelerometer and a
magnetometer, which provides us information of the tablet 3D movement speed,
orientation and gravitation forces in real-time.
