VISUAL SERVO DEVICE

摘要

PURPOSE:To improve operability by introducing a change crossing over between two pictures obtained by changing a time in the window of the picture of an object moved to a target position in a display part as the movement control data of the object and controlling a moving means. CONSTITUTION:The speed can be controlled by obtaining the movement control data directly from the change of the form element of the length (l) between side edges 18, 18 of the picture of the window 16 detected through the processing of the difference of the pictures different in time in the window 16 of the moving object 14B moved and displayed in the display part 6. Thereby, the correction error between the coordinate system of the conventional visual device and the coordinate system of a moving device is reduced to improve the operability. A picture processing time can be shortened and a control characteristic can be improved without requiring a complicate processing in picture information.
