Moving body positioning device

摘要

In order to acquire positioning results (position and azimuth) of a moving body and reducing cumulative errors in integration processing of the positioning results, a moving body positioning apparatus includes: movement detecting means for detecting whether or not a moving body is moving; position acquiring means for acquiring a position of the moving body; integrating means for integrally processing a plurality of positions acquired by the position acquiring means as positioning results; and preprocessing means for preprocessing the positioning results to be inputted into the integrating means. In accordance with output from the movement detecting means, the preprocessing means inputs the positioning results obtained from the position acquiring means into the integrating means, which integrally processes the positioning results.

1. A moving body positioning apparatus comprising:
a section for detecting or measuring any of (i) whether or not a moving body is moving, (ii) a movement speed of the moving body, and (iii) a travel distance that the moving body has traveled; a position acquiring section for acquiring a plurality of positions of the moving body as positioning results; a processor configured to integrally process the positioning results inputted therein; and a processor configured to preprocess the positioning results that are to be inputted into the processor configured to integrally process, the processor configured to preprocess inputting the positioning results obtained from the position acquiring section into the processor configured to integrally process based on output from the section for detecting or measuring, wherein a first state in which the moving body is moving is distinguished from a second state in which the moving body is not moving by the processor configured to preprocess; a data processing of the positioning results performed in the second state is different from a data processing of the positioning results performed in the first state, wherein, in the second state, the processor configured to preprocess presents an information indicative of an absence of an output; and depending on whether the moving body is moving or not, a positioning result, which needs adjustment, is selected, wherein based on the detected or measured any one of (i), (ii), or (iii), the travel distance that the moving body has traveled is determined, and when the determined travel distance is less than or equal to a predetermined threshold value, the processor configured to preprocess selects one of the positioning results, previously received, as a representative value inputted to the processor configured to integrally process.
