Abstract: State estimation and sensor fusion switching methods for autonomous vehicles thereof are provided. The autonomous vehicle includes at least one sensor, at least one actuator and a processor, and is configured to transfer and transport an object. In the method, a task instruction for moving the object and data required for executing the task instruction are received. The task instruction is divided into a plurality of work stages according to respective mapping locations, and each of the work stages is mapped to one of a transport state and an execution state, so as to establish a semantic hierarchy. A current location of the autonomous vehicle is detected by using the sensor and mapped to one of the work stages in the semantic hierarchy, so as to estimate a current state of the autonomous vehicle.

Abstract: A method and an apparatus for establishing a coordinate system and a data structure product are provided. The method includes following steps: obtaining at least one layer related to an arrangement of an indoor space to generate a layout pattern in a 2D or 3D model; obtaining locations of positioning devices located within the indoor space and labelling the locations in the layout pattern; dividing the layout pattern into multiple view tiles according to a unit area or a unit volume for displaying the layout pattern; dividing a portion of the layout pattern around the labelled positioning devices into multiple positioning tiles according to the labelled locations of the positioning devices; and selecting at least one representative point of the view tiles and the positioning tiles as a reference point to define a reference frame and establishing the coordinate system based on the reference frame.

Abstract: A ticket authentication method and a ticket authentication device are provided. The ticket authentication method includes the following steps. A first electronic device outputs an e-ticket. A second electronic device acquires the e-ticket. The second electronic device outputs a visible light verification code. The first electronic device acquires the visible light verification code and generates a composite code according to a certification data and the verification code. The second electronic device acquires the visible light composite code, and determines whether the composite code matches the certification data and the verification code. When the composite code matches the certification data and the verification code, the second electronic determines that the authentication of the e-ticket is successful.

Abstract: A system and method for combining light codes and a video are provided. The system includes an editing device and a storage device. The editing device identifies the content of a video to obtain a playback period of a plurality of frames having at least one candidate object in the video. The storage device stores at least one candidate object code and at least one light code symbol, and the light code symbol has a correspondence with the candidate object code. The editing device matches playback period of the frames having the at least one candidate object with the light code symbol, so as to provide a light code output table corresponding to the video.
