Vision Solution Design

Mech-Eye industrial 3D camera is a high-performance camera developed by Mech-Mind. It features high accuracy, fast data acquisition, resistance to ambient light, and high-quality imaging and can generate high-quality 3D point cloud data of a variety of objects. Mech-Mind offers full model options to meet the needs of ambient light resistance, high accuracy, large field of view, high speed, and small size at different distances.

In real practice, please select the appropriate model according to the working distance, field of view, and accuracy of the camera.

To select the appropriate camera model, follow these steps:

Calibration board is usually used for intrinsic parameter check and extrinsic parameter calibration, which will affect the accuracy and stability of calibration. Mech-Mind provides three calibration board models. For details, refer to Calibration Board.

In actual projects, refer to the following table and select the proper calibration board according to the camera model and the actual working distance.

You can determine the camera mounting mode based on the relative position of the camera to the robot and the needs of the overall cycle time. The following table shows two common camera mounting modes.

In addition, to expand the camera’s field of view and improve the quality of the overlapped point cloud, a project may have two or more cameras installed for one station, which is called Eye to eye (ETE).

Regardless of the camera mounting mode you choose, you will need a camera mounting frame to mount the camera. For the design description of the camera mounting frame, please refer to Camera Mounting Frame Design.

Mech-Mind IPC provides the standard operation environment for Mech-Mind’s software products and therefore can maximize the function and performance of the software.

Please select the appropriate IPC model according to the application scenarios, technical parameters, and performance technical specifications of IPCs. The performance technical specifications of the IPCs are shown in the table below.

If you use your own computer or laptop (“non-standard IPC” for short) as the industrial personal computer (IPC), please refer to Non-standard IPC Setup to make sure the non-standard IPC meets the system configuration requirements and complete the corresponding settings.

Factors such as robot payload, robot reachability, and communication mode should be considered when selecting a robot model. For details, refer to Robot Model Selection.

The interface communication mode is usually suitable for practical applications on the production line, providing more flexible functionality as well as a shorter cycle time. The Master-Control communication mode is usually applied in the testing phase of a project for quick verification of the picking effect.

For more information about how to select the communication mode, please refer to the section Communication Mode Selection. For more information about the communication modes, please refer to the section Communication Basics.

Please refer to the Select Deep Learning Solution section to determine whether to use deep learning in your vision solution.

3D matching may not solve the following problems effectively during the vision recognition process. In this case, you need to use deep learning.
