Abstract

PURPOSE: To measure the center-of-gravity being the feature point of a measuring object with high accuracy, by bringing the feature point of an object to be measured, to an image pickup, while rotating a line sensor by a rotary type actuator.
CONSTITUTION: An image pickup is started by an image pickup start command from an external control apparatus 39. In this case, unless a revolving shaft 9 turns to an origin, an actuator control part 17 executes a rotation control to a rotary type actuator 5 until it is positioned at the origin. A revolving shaft detector 11 generates a revolving shaft origin signal, when a line sensor 7 coincides with a prescribed direction, and a revolving shaft origin detecting part 19 sends this signal to a CPU25, and gives a start command to the control part 17. The control part 17 generates an actuator control signal to the actuator 5 so as to rotate by a prescribed angle. When the actuator 5 rotates, an image pickup start signal is sent to the sensor 7 from a sensor control part 33, and an image pickup of one line portion is started. This image signal is sent to an image processing part 3, processed by an algorithm, the coordinate of the center of gravity of a feature point is calculated, and the center of gravity is measured.
