Abstract
The invention relates to a method for measuring dimensions of a target object. The method comprises acquiring depth data representative of the physical space, the depth data comprising data of the target object, converting the depth data into a point cloud, extracting at least one plane from the point cloud, identifying a ground plane, eliminating the ground plane from the point cloud, extracting at least one point cluster from the remaining point cloud, identifying a point cluster of the target object, estimating dimensions of the target object based on the point cluster of the target object.
Claims18
A method for measuring dimensions of a target object, comprising:
- acquiring depth data representative of the physical space, the depth data comprising data of the target object,
- converting the depth data into a point cloud,
- extracting at least one plane from the point cloud,
- identifying a ground plane,
- eliminating the ground plane from the point cloud,
- extracting at least one point cluster from the remaining point cloud,
- identifying a point cluster of the target object,
- estimating a volume of the target object based on the point cluster of the target object.
A system for measuring dimensions of a target object, the system comprising:
- a 3D-vision device for acquiring depth data representative of the physical space, the depth data comprising data of the target object and
- a processing device for processing said depth data, wherein the processing device is configured to
- convert the depth data into a point cloud,
- extract at least one plane from the point cloud,
- identify a ground plane,
- eliminate the ground plane from the point cloud,
- extract at least one point cluster from the remaining point cloud,
- identify a point cluster of the target object,
- estimate dimensions of the target object based on the point cluster of the target object.
