    摘要： An image-measuring apparatus without axial alignment is configured to measure a workpiece. The image-measuring apparatus without axial alignment includes a rotating plate, a lighting unit, an image capturing unit, a central control unit and a rotary driving member. The workpiece is disposed on the rotating plate. The lighting unit is configured to generate a light beam to illuminate the workpiece to form a first workpiece blocking shadow area on the image capturing unit. The rotating plate and the workpiece are rotated through a rotational angle by the central control unit to form a second workpiece blocking shadow area on the image capturing unit. The central control unit calculates the first workpiece blocking shadow area and the second workpiece blocking shadow area to generate an axial position of the workpiece. There is a distance between an axial position of the rotating plate and the axial position of the workpiece.
