In this paper. we discuss the history origin of integral geometry, its product anddevelopment in the introduction. Also. the kinematic in-variant density formulas forpairs of needles and lines in R~2 and R~3 the concept and properties of chord-powerintegrals of a convex body are introduced in brief.
