Abstract
A three-dimensional measuring method comprising the following steps of: carrying out plural-time measurements with respect to a point on an object along the same line of vision using a three-dimensional measuring device; acquiring distance information on a distance between the point on the object and the three-dimensional measuring device for each measurement; determining a difference of the distance information of each point; making a decision such that the measurement is successful when the difference is smaller than a predetermined value; and making a decision such that the measurement is unsuccessful when the difference is larger than the predetermined value.
Claims11
A three-dimensional measuring system comprising:
- a measuring device for measuring a three-dimensional shape of an object;
- a movement detecting device for making a detection whether or not an object to be measured moves during measurement;
- and
- an output device for outputting a signal when a detection is made such that the object to be measured moves, the signal indicating the detection of the movement.
A three-dimensional measuring method comprising the steps of:
- carrying out plural-time measurements with respect to a point on an object along the same line of vision using a three-dimensional measuring device;
- acquiring distance information on a distance between the point on the object and the three-dimensional measuring device for each measurement;
- determining a difference of the distance information of each point;
- and
- making a decision such that the measurement is successful when the difference is smaller than a predetermined value while making a decision such that the measurement is unsuccessful when the difference is larger than the predetermined value.
A three-dimensional measuring method comprising the steps of:
- measuring a three-dimensional shape of an object;
- acquiring a plurality of two-dimensional images with respect to the object when starting or completing the measurement or during the measurement;
- determining a difference between the acquired two-dimensional images;
- and
- making a decision such that the measurement is successful when the difference is smaller than a predetermined value while making a decision such that the measurement is unsuccessful when the difference is larger than the predetermined value.
A three-dimensional measuring system comprising:
- a three-dimensional measuring device for measuring a three-dimensional shape of an object;
- a distance information acquiring device for acquiring distance information on a distance between a point on the object and the three-dimensional measuring device for each measurement by the three-dimensional measuring device;
- a difference detecting device for detecting a difference of the distance information with respect to the point on the object along the same line of vision in the measurement by the three-dimensional measuring device;
- and
- a determining device for comparing the difference with a predetermined value, and for making a decision whether measurement is successful or unsuccessful.
