1. A method for sensing and responding to a lateral blind spot of a mobile carrier, the mobile carrier comprising a host, a light scanner, and an image extraction unit, said host connected electrically to said light scanner and said image extraction unit, and said method comprising the following steps of:
said host executing a parking command indicated of
said host generating a positioning message according to a relative location or an absolute location of said mobile carrier with respective to a parking space located at one side of said mobile carrier;
said host acquiring a first moving route indicated of said mobile carrier parking to said parking space according to said positioning message and a location message of said parking space;
said host adopting said light scanner scanning the one or more objects located at and corresponding to the parking space, and said host adopting said image extraction unit extracting one or more object images corresponding to said one or more objects, and said one or more objects corresponding to a lateral blind spot of said mobile carrier;
said host filtering said one or more object images using an image optical flow method according to first moving route and giving the corresponding one or more object images as one or more filtered images according to said first moving route;
said host generating one or more predicted routes according to the corresponding one or more object vectors of said one or more filtered images; and
said host modifying said first moving route according to said one or more predicted routes and generating a second moving route correspondingly;
wherein in said step of said host modifying said first moving route according to said one or more predicted routes and generates a second moving route correspondingly, said host judges if a first effective area of said parking space is shrunk to a second effective area according to said one or more predicted routes, said first effective area is greater than a carrier size of said mobile carrier, said second effective area is smaller than said carrier size, and when said first effective area is shrunk to said second effective area, said second moving route is indicated of said mobile carrier parking to a portion of said parking space.
