Abstract
An automatic search system and a method for assisting a mobile apparatus to search for a matching device are provided. The automatic search method includes the following steps. First, N sets of consecutive images are captured at N time points respectively when the mobile apparatus moves along a first direction. The N is a positive integer greater than 1. Next, the N sets of consecutive images are received, and several image features of the N sets of images are compared, so as to determine accordingly whether the matching device exists in the first direction. If it is determined that the matching device exists, a route signal and an adjustment signal are generated. Next, according to the route signal, the mobile apparatus is controlled to move to an adjacent position of the matching device. Also, according to the adjustment signal, the mobile apparatus is controlled to be combined with the matching device.
