The invention relates to an unmanned intelligent forklift dead reckoning method based on encoder data, and provides a forklift dead reckoning device according to the encoder data of a forklift. The method is characterized in that in a closed warehouse, a GPS application scene is limited for the first time, and when an IMU is used for positioning, an IMU sensor configured on a forklift body is prone to data drifting, so that serious deviation of positioning of an intelligent forklift is caused, and therefore the method for reckoning the dead reckoning position through forklift walking encoder data and steering encoder data is provided.

    本发明涉及一种基于编码器数据的无人智能叉车航位推算方法,根据叉车的编码器数据提供一种叉车航位推算器。其特点是,在封闭的仓库中,GPS应用场景首受限,而使用IMU进行定位时,叉车车体配置的IMU传感器容易出现数据漂移,从而导致智能叉车的定位出现严重的偏差,因此提出了一种利用叉车行走编码器数据和转向编码器数据来推算航位的方法。
