To meet the needs of the log curves vectorization, roller scanner can be used to acquire geophysical log images. However, skews are inevitably introduced during the process of long image scanning. Skew correction is an important step to obtain precise digital log curves. Grid lines in log curves can be applied as the basis for skew detection. The(More)
The motion of space manipulator with a flexible base will generate interaction forces and torques acting at the base, which cannot be avoided. In order to improve the control performance of the manipulator and the vibration depressing effect of the flexible base, a kind of combined control law is proposed. That is, a resolved acceleration control(More)
