PROBLEM TO BE SOLVED: To provide a measuring device and a measuring method capable of measuring highly-accurate omnidirectional displacement inexpensively with a simple mechanism. SOLUTION: This three-dimensional displacement measuring device is characterized by having a prescribed matrix pattern 20 applied onto the surface of a measuring object 1, and a pair of image side telecentric optical systems having each main optical axis facing to the matrix pattern 20.
