The invention provides a deviation rectification method and device for a crane cart, and the method comprises the steps: carrying out the feature extraction of scanning data obtained through the scanning of a laser scanner, so as to obtain a plurality of target distance values, determining a first target edge point and a second target edge point on a running track of the crane cart according to the plurality of target distance values, and carrying out the feature extraction of the first target edge point and the second target edge point; based on the first target edge point, carrying out feature extraction on the scanning data to obtain a first feature parameter, based on the second target edge point, carrying out feature extraction on the scanning data to obtain a second feature parameter, calculating offset data of the crane cart offset track according to the first feature parameter and the second feature parameter, and according to the offset data, calculating the offset data of the crane cart offset track. And determining the deviation direction of the crane cart relative to the track, and correcting the deviation of the crane cart according to the deviation data and the deviation direction. And obtaining offset data and an offset direction through the first target edge point and the second target edge point, so as to rectify the deviation of the crane cart.

    本申请提供的一种起重机大车的纠偏方法以及纠偏装置,该方法包括:对激光扫描仪扫描得到的扫描数据进行特征提取,以获取多个目标距离值,根据多个目标距离值,确定起重机大车运行的轨道上的第一目标边缘点和第二目标边缘点,基于第一目标边缘点,对扫描数据进行特征提取,以得到第一特征参数,基于第二目标边缘点,对扫描数据进行特征提取,以得到第二特征参数,根据第一特征参数以及第二特征参数,计算起重机大车偏移轨道的偏移数据,根据偏移数据,确定起重机大车相对于轨道的偏移方向,根据偏移数据和偏移方向,对起重机大车进行纠偏。通过第一目标边缘点以及第二目标边缘点获取偏移数据以及偏移方向,从而对起重机大车进行纠偏。
