Abstract: A method of tracking target object includes following steps of: controlling a following robot to capture a target object for obtaining a comparison image; determining in the comparison image a plurality of sampling particles corresponding to the target object; calculating a predicted position of each sampling particle; moving toward a predicted direction corresponding to the predicted positions for following the target object; re-sampling the sampling particles according to a difference between a reference image and the comparison image; configuring the compare image as the new reference image; and, performing above-mentioned steps repeatedly until the following robot stops following the target object. Therefore, the analysis efficiency and stability of tracking effectively can be improved; the real-time following and the following robot operate without a signal transmitter can be achieved as well.

Abstract: A method of tracing target object is provided. The method includes following steps of: controlling a following robot to capture a target object for obtaining a compared image; determining in the compared image a plurality of sampling particles corresponding to the target object; calculating a predicted position of each sampling particle; moving heading to a predicted direction corresponding to the plurality of the predicted positions for following the target object; re-sampling the plurality of the sampling particles according to a difference between a reference image and the compared image; configuring the compare image as the new reference image; and, performing above-mentioned steps repeatedly until stopping following. Therefore, the analysis efficiency and stability of tracing effectively can be improved; the real-time following and the following robot operate without a signal transmitter can be achieved as well.
