Depending on the detection and desired insights, it is essential to select the best performing components. Each project is based on the following pillars, which are extensively tested in our own test lab.
We make informed decisions when developing a vision system. If you are considering automatic in-line detection, then please get in touch. Together, we will work out a solution that meets your every need and provides objective insight into the margin of error.
In order to be able to detect objects in production, the right lighting is required. If the subject is under-exposed or not sufficiently exposed, the analysis algorithm in the system is unable to detect the subject correctly.
Selecting and configuring the lighting is, therefore, one of the most crucial factors when designing a vision system. Lighting is determined depending on detection, and includes colour, texture, size, shape, ability to reflect, etc.
OPTICS AND CAMERAS
A camera consists of a lens and a sensor. It is the lens that captures the light, which is scattered on the object to be inspected. The sensor reconstructs all information into an image.
When selecting a camera, three elements are considered:
- the performance of the sensor
- the camera
- the interface technology and image transfer
A vision system uses analogue and digital electronics, grounding techniques, and requires EMC and ESD knowledge.
ACQUISITION AND TRANSFERENCE
Acquisition technology has seen major changes in recent years, notably the introduction of new bus technologies.
Traditional framegrabber technology is connected by a series of generic interfaces, such as FireWire and USB (2.0 and 3.0), together with Gigabit Ethernet.
The basis of all graphic software is the camera’s ability to acquire pixel data, transmit, manipulate and interpret them, but what happens to these images? They may be stored, or used in a complex application, such as pattern recognition.
When selecting a computer intended for imaging applications, we take many factors into account. For example, the PC must be powerful enough to deliver the required performance, reliable in the long run and guarantee stability.
