Abstract
A system which includes a mobile device and a server. The mobile device captures images of the survey site. A pose sensor detects the pose of the mobile device. The captured images are transferred to a data processor running a 3D reconstruction algorithm. The 3D reconstruction algorithm generates 3D survey data based on the images which is used to develop a local 3D model. The data processor also uses the images to create processed data. A transceiver transmits the processed data and/or pose data to the server. The server receives the 3D survey data and develops a server site 3D model.
Claims15
A surveying system for surveying in harsh environments, the surveying system comprising:
- a mobile device comprising:
- a casing defining a sealed enclosure;
- and
- an imaging device;
- a first data processor;
- a first computer memory;
- a pose sensor arranged to determine pose data representing a pose of the mobile device;
- a first data transceiver;
- wherein the first data processor is arranged to:
- receive images from the imaging device and execute a first 3D reconstruction algorithm to generate 3D survey data from the received images and develop a local 3D model on the computer memory;
- process the received images to form processed data;
- and
- cause the first data transceiver to transmit the processed data and/or the pose data for receipt by a server, wherein the first data processor is arranged to execute a model refinement algorithm to develop the local 3D model in response to receipt of refined 3D survey data from the server via the first data transceiver.
A method of surveying in harsh environments, the method comprising:
- receiving images from an imaging device;
- determining pose data representing a pose of the imaging device;
- processing the received images to generate a local 3D model and processed data;
- transmitting from a transceiver the processed data and/or the pose data for receipt by a server;
- receiving refined 3D survey data from the server via the transceiver;
- and,
- processing the refined 3D survey data to identify errors and correct the positions of features within the local 3D model.
