The invention relates to the related technical field of engineering machinery, in particular to a container truck anti-hoisting monitoring method and device and a crane, firstly, when a target container truck is not hoisted, a preset scanning device scans the target container truck to obtain a reference point cloud set; scanning again through a preset scanning device at a monitoring moment to obtain a real-time reference point cloud set; the scanning devices are used for scanning the first plane. Thus, no matter how the appearance of the container truck is, as long as the target container truck is hoisted, the real-time point cloud set obtained by scanning the fixed plane by the scanning device changes relative to the reference point cloud set due to the scanning information of the first plane before and after the container truck is hoisted, so that the real-time point cloud set is obtained according to the change data of the two point cloud sets. Therefore, whether the container truck is lifted or not can be directly identified.

本申请涉及工程机械相关技术领域，具体涉及集卡防吊起监测方法、装置和起重机，首先在目标集卡未被吊起时，通过预设扫描装置扫描所述目标集卡得到的参考点云集合；然后在监测时刻，通过预设扫描装置再次进行扫描，获取实时参考点云集合；其中，扫描装置均用于扫描第一平面。如此，无论集卡外形如何，因为前后均为第一平面的扫描信息，只要当目标集卡被吊起时，扫描装置扫描固定平面得到的实时点云集合相对于参考点云集合，就一定发生变化，所以根据两个点云集合的变化数据，就可以直接识别出集卡是否被吊起。
