Abstract
The present invention relates to a wrinkle measurement apparatus and a wrinkle measurement method. The wrinkle measurement apparatus according to one embodiment of the present invention comprises: a surface direction compression part including first and second contact parts arranged at a preset gap while coming into close contact with the skin, so as to compress the skin in the direction of the surface thereof; and a wrinkle measuring part for measuring skin wrinkles in at least two states among pre-compression, mid-compression and post-compression.
Claims6
A wrinkle measuring device, comprising:
- a skin compressor comprising first and second contact units placed in close contact with skin at a preset interval to compress the skin toward the skin surface to create wrinkles artificially;
- and
- a three-dimensional image measurement device configured to measure skin wrinkle by three-dimensional image measurement of the skin in at least two of a state before compression of the skin, a state during compression of the skin by the skin compressor, and a state after compression of the skin by the skin compressor;
- and
- wherein the three dimensional image measurement device measures skin elasticity in a form of time or length or area based on
- a difference in a length or an area of wrinkle between before and after compression of the skin by the skin compressor or between during and after compression of the skin by the skin compressor, or
- a restoration time taken for wrinkle after compression of the skin by the skin compressor to return to a state before compression.
A wrinkle measuring method, comprising:
- compressing, by first and second contact units placed in close contact with skin at a preset interval, the skin toward the skin surface during a preset period of time to create wrinkles artificially by adjusting the interval between the first and second contact units;
- measuring skin wrinkle by three-dimensional image measurement of the skin in at least two of a state before compression of the skin, a state during compression of the skin by the first and second contact units, and a state after compression of the skin by the first and second contact units, a state after compression of the skin by the first and second contact units, and skin elasticity based on
- a difference in a length or an area of wrinkle between before and after compression of the skin by the first and second contact units or between during and after compression of the skin by the first and second contact units, or
- a restoration time taken for wrinkle after compression of the skin by the first and second contact units to return to a state before compression.
