First Claim
Patent Images
1. A three-dimensional shape and color detecting apparatus that detects a three-dimensional shape of an object and a color thereof, comprising:
- (A) a three-dimensional shape measuring system that includes;
a slit light beam emittin system that emits a slit beam to the object; and
a three-dimensional shave detecting system that detects the three-dimensional shape of the object in accordance with an image of an object at a portion illuminated by the slit beam; and
(B) a color measuring system that includes;
an illuminating system that emits light to illuminate the object, said illuminating system illuminating the object such that a predetermined area of the object is illuminated simultaneously with light having a substantially even light intensity; and
a light receiving device that receives a reflected component of the light from the object illuminated by said illuminating system to detect a color.

Abstract
A three-dimensional shape and color detecting apparatus that detects a three-dimensional shape of an object and a color thereof is provided with an illuminating system that emits light to illuminate the object, and a light receiving device that receives a reflected component of the light from the object. In this structure, the illuminating system is configured to emit the light from a surface having a predetermined area to the object.

a light source; and
a light diffusing member that diffuses the light emitted by said light source.
-
-
8. The apparatus according to claim 7, wherein said light source is arranged, when viewed from the object side, behind said light diffusing member.
-
9. The apparatus according to claim 7, where said light source is arranged, when viewed from the object side, on a near side of said light diffusing member.
-
10. The apparatus according to claim 1, further including a rotary table on which the object is held.
-
11. The apparatus according to claim 1, further including a light shielding member that prevents ambient light from being incident on the object.
-
12. The apparatus according to claim 1,
wherein light emission of said illuminating system is inhibited when the three-dimensional shape of the object is measured, and wherein emission of the slit beam of said slit light beam emitting system is inhibited when the color of the object is measured. -
13. The apparatus according to claim 1, further includes a scanning system that moves said slit beam emitting system and said light receiving device relative to the object in a direction perpendicular to an extending direction of the slit beam so as to scan the object with the slit beam.
-
14. The apparatus of claim 1 wherein said illuminating system is a surface light source.
-
15. A three-dimensional shape and color detecting apparatus that detects a three-dimensional shape of an object and a color thereof, comprising:
-
a slit beam emitting system that emits a slit beam to the object, cross section of the slit beam being extending in a predetermined direction;
an illuminating system that emits illuminating light having substantially an even intensity distribution toward entire area of the object, thereby illuminating an area of the object simultaneously; and
a light receiving device that receives an illuminated portion of the object, wherein, when the three-dimensional shape of the object is detected, the slit beam is emitted to the object and the reflected beam is received by said light receiving device, wherein, when the color of the object is detected, the illuminating light is emitted to the object and the reflected beam is received by said light receiving device; and
wherein when color is measured, a predetermined area of the object is illuminated simultaneously with light having a substantially even light intensity. - View Dependent Claims (16, 17, 18, 19)
said controller inhibiting light emission of said illuminating system when the three-dimensional shape of the object is measured, and said controller inhibiting emission of the slit beam of said slit light beam emitting system when the color of the object is measured.
