A surveying device, comprising a first image pickup unit for projecting a laser beam and for receiving a reflection light from a target, a second image pickup unit for acquiring an image including the target, drive units for shifting collimating directions of the image pickup units, an image processing unit for processing images taken by the image pickup units, and a control arithmetic unit for controlling the drive units so that the image pickup units are directed toward the target is disclosed. The image processing of the image by the first image pickup unit is a light spot detection processing. The image processing of the image by the second image pickup unit is an image matching with a template image. The control arithmetic unit controls the drive units so that the target is tracked based on the result of the light spot detection processing or the image matching.
