Stripe Engine

The Stripe Engine is the default Vision Engine for Zivid 2+. It is built for exceptional point cloud quality in scenes with specular reflective objects. The Stripe Engine has a high dynamic range and thus provides great point cloud coverage. This makes the engine suitable for applications such as factory automation, manufacturing and bin picking.

The Stripe Engine is developed specifically to handle scenes with for example:

  • Metallic cylinders

  • Automotive parts

  • Sheet and plate metal

  • Polished metal

  • Chrome-plated parts

  • Stacked metallic objects

The following filters must be enabled when capturing with Stripe Engine:

Camera

Contrast Distortion Filter

Zivid 2

Yes

Zivid 2+

Optional

Point cloud quality

The Stripe Engine is less sensitive to noise produced by interference from ambient light sources, reducing the need to compensate with 50Hz/60Hz exposure time.

Dynamic range

It has a high dynamic range, and is therefore less sensitive to:

  • Highlights

  • Blooming effects

  • Reflections from ambient light sources

  • Direct reflections from the projector

This results in less penalty when the camera points straight down into a bin and other objects.

The Stripe Engine has better point cloud coverage than the Sage Engine. However, the 3D data under the influence of reflections can be less accurate.

Highly specular cylinders

Tip

If your scene includes highly reflective specular (shiny) objects and you prefer a complete point cloud over having only reliable points, then the Stripe Engine is the best choice.
