Terra Drone India has successfully completed a multi-sensor, multi-platform scanning of internationally recognized landmark Charminar.
Built in 1591, the monument, known as the ‘Arc de Triomphe of the East’, suffered significant damage in May 2019 when a huge chunk of lime-plaster from its south-west minaret broke and fell off.
The incident made the digital preservation of Charminar extremely time-sensitive and important for the Indian government.
Therefore, the IT department of Telangana state government invited Terra Drone India to provide innovative technological solutions for the digital preservation of Charminar.
The firm scanned and surveyed the damaged minaret using multiple technologies.
The solution-set included Air Gap Measurement through Ultrasonic Pulse Velocity Testing technique, True Color 3D Model Creation using Visual (RGB) Sensor, Thermal Scanning and LiDAR 3D Profiling and Model Generation using LiDAR.
Commenting on the work, wing commander Polu Sreedhar, COO, at Terra Drone India, commented: “Heritage monuments like Charminar are the treasures of our nation and symbolize the pride of our civilization.”
He added: “Terra Drone India has collated multiple technologies under one umbrella and provided it as a holistic solution to the Archaeological Survey of India to help preserve the monument that speaks volumes about our Indian heritage, culture and ancestral prominence.”
