Abstract
Abstract In a three dimensional measurement system, a three dimensional pickup apparatus picks up an object repeatedly to generate image information including a shape of the object, and an information processor receives image frame signals and digital signals from the pickup apparatus to process the image information. Image information is sent as image frame signals through a first output terminal, and digital signals are sent through a second output terminal in correspondence to output of the image information through the first output terminal. In the information processor, an input controller receives the digital signals from the first output terminal and receives the image frame signals suitable for transmission of moving images in correspondence to the received digital signals from the second output terminal. For example, the pickup conditions for a next period are set based on the pickup information obtained in a current period. For example, a distance sensor is provided further to adjust the pickup conditions in various ways in continuous pickup mode.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
112 words
A three dimensional pickup apparatus which picks up an object to generate image information including a shape of the object, said apparatus comprising: a pick-up device which picks up an object; a condition setter for setting pickup conditions of the pick-up device; an imaging controller for performing pickup operation repeatedly in correspondence to a start signal; wherein said condition setter sets the pickup conditions in a first mode before each pidkup operation so that each pickup operation is performed in pickup conditions updated before the pickup operation and said condition setter sets the pickup conditions in a second mode once so that each pickup operation is performed in the same pickup conditions.
Claim 2
Dependent Claim
112 words
A three dimensional pickup apparatus which picks up an object to generate image information including a shape of the object, said apparatus comprising: a pick-up device which picks up an object; a condition setter for setting pickup conditions of the pick-up device; an imaging controller for performing pickup operation repeatedly in correspondence to a start signal; wherein said condition setter sets the pickup conditions in a first mode before each pidkup operation so that each pickup operation is performed in pickup conditions updated before the pickup operation and said condition setter sets the pickup conditions in a second mode once so that each pickup operation is performed in the same pickup conditions.
Claim 3
Dependent Claim
31 words
The three dimensional pickup apparatus according to claim 1, wherein said condition setter sets the pickup conditions according to a position of the object relative to said three dimensional pickup apparatus.
Claim 4
Dependent Claim
63 words
The three dimensional pickup apparatus according to claim 2, wherein said pick-up device comprises a projection unit which projects a slit light to an object while changing a projection angle of the slit light and a light-receiving unit which receives a light reflected by the object, and said condition setter sets an intensity of the projection light as one of the pickup conditions.
Claim 5
Dependent Claim
67 words
The three dimensional pickup apparatus according to claim 1, wherein said pick-up device comprises a projection unit which projects a slit light to an object while changing a projection angle of the slit light and a light-receiving unit which receives a light reflected by the object, and said condition setter sets a range of the projection angle of said projection unit as one of the pickup conditions.
Claim 6
Dependent Claim
84 words
A three dimensional pickup apparatus which picks up an object to generate image information including a shape of the object, said apparatus comprising: a pick-up device which picks up an object; a condition setter for setting pickup conditions of the pick-up device; and a pickup controller for performing pickup operation repeatedly in correspondence to a start signal; wherein said condition setter sets the pickup conditions before each pickup operation so that each pickup operation is performed in pickup conditions updated before the pickup operation.
Claim 7
Dependent Claim
84 words
A three dimensional pickup apparatus which picks up an object to generate image information including a shape of the object, said apparatus comprising: a pick-up device which picks up an object; a condition setter for setting pickup conditions of the pick-up device; and a pickup controller for performing pickup operation repeatedly in correspondence to a start signal; wherein said condition setter sets the pickup conditions before each pickup operation so that each pickup operation is performed in pickup conditions updated before the pickup operation.
Claim 8
Dependent Claim
31 words
The three dimensional pickup apparatus according to claim 5, wherein said condition setter sets the pickup conditions according to a position of the object relative to said three dimensional pickup apparatus.
Claim 9
Dependent Claim
67 words
The three dimensional pickup apparatus according to claim 5, wherein said pick-up device comprises a projection unit which projects a slit light to the object while changing a projection angle of the slit light and a light-receiving unit which receives a light reflected by the object, and said condition setter sets a range of the projection angle of said projection unit as one of the pickup conditions.
Claim 10
Dependent Claim
63 words
The three dimensional pickup apparatus according to claim 5, wherein said pick-up device comprises a projection unit which projects a slit light to the object while changing a projection angle of the slit light and a light-receiving unit which receives a light reflected by the object, and said condition setter sets an intensity of the projection light as one of the pickup conditions.
Claim 11
Dependent Claim
78 words
A three dimensional pickup apparatus which picks up an object to generate image information including a shape of the object, said apparatus comprising: a pick-up device which picks up an object; a condition setter for setting pickup conditions of the pick-up device; an imaging controller for performing pickup operation repeatedly in correspondence to a start signal; wherein said condition setter sets the pickup conditions once so that each pickup operation is performed in the same pickup conditions thereafter.
Claim 12
Dependent Claim
