The invention relates to a test method for a mobile platform. The test method is characterized by comprising the following steps of: judging to correctly track the mobile platform according to a walking path video signal; reproducing a walking path, converting the walking path video signal into a moving track image, and dividing the moving track image into an overlapping area through which the mobile platform accumulatively passes and a non-overlapping area where the mobile platform does not pass through; and evaluating the walking path of the mobile platform according to the overlapping areainformation and displaying the overlapping efficiency of the mobile platform. The invention also relates to a test system for the mobile platform. The test system comprises a computer, and a video acquisition device and a display device which are connected with the computer respectively, wherein a display window of the display device comprises an overlapping efficiency displaying window used for displaying the evaluation information of the walking path and the overlapping efficiency of the mobile platform. The test method and the test system for the mobile platform can more precisely acquire the walking path track and overlapping efficiency of the mobile platform and effectively evaluate the overlapping algorithm and working efficiency of the mobile platform so as to provide reference forimproving the path planning algorithm and working efficiency of the mobile platform.
