Abstract: In tracking of a moving body using image data in detecting a target moving body having few externally outstanding features, such as coloring and a shape, from an image in an image frame, if an image of the target moving body overlaps a background image largely and their colorings are the same or similar to one another, it is difficult to detect the target moving body. A template image of the target moving body is superimposed on a background image of a region (periphery) of a candidate position of the target to generate a composite image and the moving body is detected based on a degree of match calculated through comparison of the composite image with an image of the region (periphery) of the candidate position of the target.

Abstract: When the deceleration start point is reached, the meter-in side of the hydraulic driving actuator is subjected to a flow rate control to thereby start the deceleration control processing. The position to which the movable unit is moved is detected to use a speed instruction corresponding to the movement position to subject the hydraulic driving actuator to a meter-in control. The position to which the movable unit is moved is detected to calculate the moving speed of the movable unit. Based on the speed instruction, the moving speed is subjected to the feedback control using the meter-out control to the hydraulic driving actuator.
