This book deals with the fundamentals of computational photogrammetry and offers solution of problems through mathematical computations by using measurements made on photographs as input data. Delineating its basic principles and application expansion, it discusses at length instrumentation, coordinate systems, geometry of photographs, refinement of photo coordinates, relationship between object and photo, design of projects, multiple-photo applications and self-calibration as well as constraints. People applying photogrammetry in fields like surveying, mapping, civil engineering, geology, forestry, agriculture, space technology, crime investigation and microscopy will find the book very useful.
