The utility model provides a remote controller. The remote controller comprises a laser emitting unit for emitting laser, an image obtaining unit, an image processing unit, a triggering unit, a first wireless transmission unit, and a remote controller control unit, wherein the image obtaining unit is used for acquiring the incident point of the laser and the image information of a screen on which the laser projects; the image processing unit is used for determining laser incident point coordinate information according to the image information including the laser incident point and the screen; and the remote controller control unit is connected with the laser emitting unit, the image obtaining unit, the image processing unit, the triggering unit and the first wireless transmission unit. The utility model further provides a television remote control system. The laser incident point is projected to the television screen by a laser head on the remote controller, the screen image information projected by the laser head is obtained through a camera on the remote controller, and the position information of the laser incident point, formed by laser projection, in the television screen is analyzed from the obtained image information, and thus television screen location can be achieved just by operating the laser head on the remote controller to emit laser.
