摘要： There are provided a target detection method and detection device that include a calibration function and can maintain detection accuracy of a target irrespectively of a change (such as a temperature) in external environment.
A target detection method includes: a step of calculating a quantitative value; a step of, at a first position information generation device, measuring a first target; a step of, at a second position information generation device, measuring a second target; a step of calculating a position of the second target using the first position information generation device as a position reference based on a measurement value of the first target obtained by the first position information generation device, a measurement value of the second target obtained by the second position information generation device, and the quantitative value; and a step of calibrating the quantitative value before measuring a third target using the second position information generation device.

摘要： There is provided a target detection method and detection device that can detect a target by a simple method and configuration.
A target detection method includes: a step of, at a first position information generation device, measuring a position and a posture of a first target; a step of, at a second position information generation device, measuring the position and the posture of the first target; a step of calculating a position and a posture of one of the first position information generation device and the second position information generation device with respect to other one of the first position information generation device and the second position information generation device based on a difference between the position and the posture of the first target measured by the first position information generation device, and the position and the posture of the first target measured by the second position information generation device; and a step of, at the second position information generation device, measuring a position and a posture of a second target using the position and the posture of the one of the first position information generation device and the second position information generation device with respect to the other one of the first position information generation device and the second position information generation device.

摘要： There are provided a positioning method and a positioning device that can position workpieces by a simple method and configuration. A positioning method includes: gripping at least one of first and second workpieces; obtaining point group data of the at least one gripped workpiece of the first and second workpieces; calculating a translation matrix of shape fitting point group data obtained by adjusting a position of the point group data to reference data in a position adjustment state of the first and second workpieces; calculating an inverse matrix based on the translation matrix; and positioning the first and second workpieces by moving the at least one gripped workpiece of the first and second workpieces based on at least one of the translation matrix and the inverse matrix.
