Terms and Concepts

A resource library containing numerous practical features and industry cases.

A solution is a collection of functional configurations and data for robot, communication, vision processing, and path planning required for a vision application.

Projects refer to Mech-Vision projects. A project must belong to a solution, or else it cannot be used. In addition, a solution may include multiple projects. Projects cannot be used independently and must belong to a solution.

Steps are the basics of a project. A Step is a minimum algorithm unit for data processing. By connecting different Steps in a project, you can achieve different data processing tasks.

A Procedure groups the Steps whose functions are closely related and achieve a specific purpose concertedly in the project.

Parameter recipes are sets of parameter settings that need to be adjusted according to different situations for the same project. With parameter recipes, you do not need to build multiple projects with the same logic and configure their parameters differently to meet different on-site requirements. Instead, you will only need to switch between parameter recipes in one project to make it applicable to various scenarios and therefore the productivity can be increased.

Hand-eye calibration establishes the transformation relationship between the camera and robot reference frames. With this relationship, the object poses determined by the vision system can be transformed into those in the robot reference frame, which guides the robot to perform its tasks.

The camera intrinsic parameters describe the internal properties of the camera. These parameters are typically fixed for a specific camera model and remain unchanged during the camera’s usage.

The camera extrinsic parameters describe the position and orientation of the camera in the world coordinate system.

Euler angles are used to describe the orientation of an object in the 3D space. The object’s rotation in the 3D space can be denoted by 3 angles, i.e., pitch, yaw, and roll.

Tool center point is the pinpoint at the end of the robot tool. In order to complete tasks such as picking, we usually say that the robot should move to a specific point in space, which actually means its TCP should move to that point.

A point cloud is a collection of points in the 3D space, each containing at least three coordinate values (X, Y, Z), used to describe the geometric shape of an object’s surface accurately.

Pose describes the posture of an object by defining its position and orientation.

Specified images, shapes, or objects are usually selected to mask the image (partial or all) to control the area to process or the processing. The particular image or object used for masking is called a mask.

The region of interest excludes surrounding parts unnecessary for vision data processing in the scene. Such parts may be background objects, pallets, bin edges, etc.

After a model has been trained in Mech-DLK, it can be exported as a model package, which contains one or more models. In Mech-Vision, the model package can be used for the inference of the image data.

A universal model provided by Mech-Mind used to recognize cartons or sacks. If the recognition performance is unsatisfactory, Mech-DLK can be used to fine-tune the model.
