Integrating a module to 3d scan a house within the MapMint4ME android application

Introduction

Introduction of MapMint

MapMint4ME is an Android application to record your data on the field. MapMint4ME is an Android application for MapMint web-mapping services. MapMint4ME gives the users capability to store data without using the internet locally. The data can be a file stored in alpha-numeric format, an audio file, a video file or readings obtained from a Sensor Observation Service (SOS). When the user returns back to a place with network connectivity, the recorded data can be uploaded back to the server.

MapMint4ME is an android application for MapMint web-service. MapMint is an internet-based Geographic Information System(GIS), designed to facilitate the deployment of Spatial Data Infrastructure(SDI). In an SDI, geographic data, metadata, tools, and the users are connected in an interactive manner in a framework so as to use the spatial information in an efficient and flexible way.

Project proposal

My proposal for GSoC 2021.

Abstract

This project allows a minimalist 3D scan (taking multiple pictures, recording camera position, using opendrone map to rebuild the 3D scene) with the house faces (accessible/visible faces) then load it as georeferenced data with the database and being able to export the data back on MapMint for 3D viewing.

Week Five: 5th - 11th July

• What have I done this week:
  • Still working on the Zoo Service configuration file needed to create the zoo service to get the data from ODM.
  • Still working on the serviceProvider get_3d_model.py  : the python script that will be used to get the 3D model from ODM.

• My plans for next week:
• Continue working on getting the zoo service up and running

• Am I blocked on anything:
