Embodiment Construction

[0027] (1) Establish coordinates: establish the spatial coordinates constructed by the sensor according to the characteristics of the sensor, and establish the absolute value coordinates of the space in the objective real environment at the same time; The origin of coordinates, related measurement methods and coordinate three-dimensional directions that can be converted to each other unify the spatial coordinates constructed by the sensor with the absolute value coordinates of space in the objective real environment, and then establish the real-time coordinate values ​​of the object scan and the real-time position of the actual object One-to-one correspondence, forming a unified object outline coordinates and object position parameters.

[0028](2) Contour scanning and data collection: collect object contour and position data through sensors, and the position of each point of the collected object contour is expressed in the form of point cloud collection and saved as a complete...

Abstract

The invention discloses an intelligent real-time material position coordinate recognition and random point sampling method. The steps comprises: (1) establishing and correlation method of space coordinates constructed by a sensor and space absolute coordinates in an objective reality environment; (2) car body real-time data collection. (3) car body and cargo outline recognition; (4) a random point generation method in a cargo real-time coordinate; and (5) a human-computer interface.

Description

technical field [0001] The present invention is mainly used in the fields of transportation, logistics management and industrial production. Through the present invention, a three-dimensional object scanning platform is established. The three-dimensional object scanning platform forms a complete data file for the data scanned by the vehicle. Parts are distinguished, and then the part of the goods is selected, and random points are generated in the part of the goods, that is, the method of analyzing and identifying objects through three-dimensional data points, and then generating random sampling points. The present invention is mainly applicable to object recognition and positioning. Background technique [0002] Car recognition based on three-dimensional data points belongs to the segmentation problem of point cloud data. [0003] The segmentation of point cloud data is to divide the data into several disjoint subsets, and the data in each subset belong to a surface with a...
