Terms and Concepts

A resource library that provides typical solutions or projects (with example data) coming from different application scenarios.

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

A project refers to a Mech-Vision project. One or more projects constitute a solution. 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 process 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.

Intrinsic parameters are measures of the properties of a camera itself, including the focal length, the lens distortion, etc. These parameters are usually calibrated and stored in the camera before the camera leaves the factory.

Extrinsic parameters define how poses are transformed between the camera reference frame and the world reference frame.

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 set of data points in space that represents a 3D shape or object.

The position and orientation information that are used to guide the robot.

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.
