3D Model Of Aravali College Of Engineering And Management
Developed during the 3rd semester of the B.Tech program, this project involved designing and constructing a highly accurate physical scale model of the Aravali College of Engineering and Management campus. The execution required a blend of physical crafting and digital problem-solving to reverse-engineer missing architectural data.
The Challenge: Working with Limited 2D Data
The primary reference material provided by the college was a standard 2D map blueprint. Since the reference photos of the blueprint were captured via a mobile phone, they lacked precise scale and structural height information. While mapping the 2D footprint was straightforward, calculating the Z-axis (elevation) of the buildings presented a significant structural hurdle.
The Technical Solution: Photogrammetry & AutoCAD
To accurately determine the building heights without official elevation drawings, a hybrid approach combining photography, digital perspective correction, and CAD software was utilized:
- Data Collection: Captured distant front and back profile photographs of the campus using a smartphone to acquire the raw elevation profiles.
- Angle & Perspective Correction: Since the photos were taken from ground level (creating a perspective distortion), mathematical angle calculations and Adobe Photoshop were used to flatten and correct the images into true orthographic elevations.
- Scaling in AutoCAD: The perspective-corrected images were imported directly into AutoCAD. By cross-referencing the known dimensions from the 2D map footprint, the digital images were scaled to match perfectly.
- Extracting Measurements: This AutoCAD model allowed for precise extraction of window sizes, floor heights, and the overall building dimensions. These baseline measurements were then used to calculate the relative scale of surrounding objects.
Materials & Physical Construction
With the scaled measurements locked in digitally, the physical construction of the prototype was executed using Sunboard and Wood. The lightweight yet rigid nature of sunboard allowed for precise cutting of the complex architectural geometries, resulting in a robust, mathematically accurate physical representation of the campus.
