Embodiment 1
[0045] Such as figure 1 As shown, a radioactive waste package identification and positioning method, making waste package point cloud templates and shielding container point cloud templates, using a two-stage matching algorithm to identify the pose of the shielding container and the waste package for identification and positioning , load or unload the waste package according to the result of identification and positioning, the specific steps are as follows:
[0046] S1. Collect the point cloud of the scene through the laser scanning sensor, extract the point cloud of the effective area of the calibrated lane, perform noise reduction filtering to remove random outliers, and extract the ground point cloud;
[0047] S2. Remove the ground point cloud, and cluster the object point cloud in the scene to obtain the point cloud of each object, and obtain the clustered vehicle point cloud and shielding container point cloud through screening;
[0048] S3. Apply the shielded containe...

The invention discloses a method and device for identifying and locating a radioactive waste package. The method includes: making a waste package point cloud template and a shielding container point cloud template, and identifying the pose of the shielding container and the waste by using a two-stage matching method using environmental constraint feature vectors. The pose of the package is used for identification and positioning, and the waste package is loaded or unloaded according to the result of the identification and positioning. The invention realizes the identification and precise positioning of the posture and internal state of the shielded container, realizes the precise identification and positioning of the package in the shielded outer box, and solves the identification and positioning of the package in the box that cannot be solved by traditional techniques that are sensitive to ambient light and occlusion. question.
Description
technical field [0001] The invention relates to the technical field of cargo identification and positioning, in particular to a radioactive waste package identification and positioning method and device. Background technique [0002] Package identification and positioning technology is the most basic and key technology in unmanned cargo handling scenarios. The stability and accuracy of identification and positioning directly affect the reliability of the entire loading and unloading system. In order to complete the accurate loading and unloading process, it is necessary to identify and locate the transfer container on the transfer vehicle and the waste package in the container. [0003] For the scene of the package in the outer box, there is currently no effective identification and positioning method. The traditional package positioning and identification method is aimed at locating independent packages. The methods are mainly divided into three ways: relying on position s...
