Title:
THREE-DIMENSIONAL OBJECT MEASUREMENT METHOD
Document Type and Number:
Japanese Patent JPH0520438
Kind Code:
A
Abstract:
PURPOSE: To obtain a reflection coefficient on the surface of a three-dimensional object in short period with a simple operation.
CONSTITUTION: The three-dimensional object is rotated at a prescribed angler velocity around a y-axis, and the picture of N+1-number of frames is stored in video RAM 5. Partial differential values for N-times in respective points on the two-dimensional picture of the respective frames are operated in a work station 6, and the reflection coefficient on the surface of the three-dimensional object 1 is obtained by using the partial differential values.
