The invention relates to the field of positioning algorithms of digital twinborn scenes, in particular to a method for positioning port hoisting equipment in a digital twinborn scene, which comprises the following steps of: S1, constructing a virtual model of a storage yard square according to longitudes and latitudes of four corners of a storage yard area; s2, acquiring the longitude and latitude of the position of the GPS on the hoisting equipment, and judging whether the hoisting equipment is in a storage yard area or not; s3, correcting the point location of the hoisting equipment by comparing the real-time latitude and longitude and the historical latitude and longitude data of the hoisting equipment; compared with the prior art, the positioning method has the advantages that by judging and correcting the real-time position of the hoisting equipment and the position relation between the hoisting equipment and the correction reference line, corresponding correction of the original longitude and latitude is achieved, and it is ensured that the position of the hoisting equipment is accurately displayed in the digital twin environment.

    本发明涉及数字孪生场景的定位算法领域,具体涉及一种港口吊装设备在数字孪生场景下的定位方法,包括:S1:根据堆场区四角经纬度构建堆场广场的虚拟模型;S2:获取吊装设备上GPS所在位置的经纬度,判断吊装设备是否在堆场区域;S3:通过比对吊装设备的实时经纬度与历史经纬度数据,矫正吊装设备所在点位;与现有技术相比,本发明的有益效果是:本发明所述的定位方法通过判断及矫正吊装设备的实时位置,及其与矫正参考线的位置关系,实现了对原始经纬度的相应矫正,确保吊装设备位置在数字孪生环境中准确显示。
