Question

The method which is used for three dimensional reconstruction of crime scene that requires many parts of the crime scene to be measured for determining the height and size of evidence is known as:

• A. Anthropometry
• B. Photogrammetry
• C. Geometry
• D. Micro colourmetry

Hint:

Break down the word: \textbf{Photo} (light/picture) + \textbf{Gram} (drawing/writing) + \textbf{Metry} (measurement). Photogrammetry is literally "measuring from pictures."

Answer 1

The Correct Option is B

Step 1: Analyze the description. The question describes a method for 3D reconstruction and taking measurements (height, size) from a series of images of a crime scene.

Step 2: Define the terms.
(1) Anthropometry: The scientific study of the measurements and proportions of the human body.
(2) Photogrammetry: The science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring, and interpreting photographic images. This perfectly matches the description of making 3D measurements from photos.
(3) Geometry: A branch of mathematics concerned with properties of space. It is the underlying principle but not the name of the applied technique.
(4) Micro colourmetry: The measurement of the color of microscopic objects.
Conclusion: The correct term for this technique is Photogrammetry.
