Machine Vision | Cameras In Applications


Machine vision is a subset of computer vision, which is the process of using computers to extract information from digital images. This can be done through an array of different machine vision applications, such as object detection, image segmentation and tracking. A camera is a necessary piece of equipment for your machine vision application. There are many factors that contribute to the decision of what type of camera to buy. For example, whether you need a monochrome or color camera, or if you want them to be low-light or high-light sensors. Here are some key considerations when buying cameras for machine vision applications.

Considerations when buying a camera

When you’re buying a camera for your machine vision application, there are a few key considerations.

– Image resolution: the higher the better

– Field of view: this is the coverage area of your camera

– Sensor size: this will impact what types of algorithms your camera uses

– Light sensitivity: low light sensors make it easier to see in low light conditions

– Lens type: whether you want an uncooled or cooled sensor lens, and if you need to mount a filter on them

What machine vision applications are suitable for a camera?

In order to find a camera that is suitable for your application, you’ll need to know what type of machine vision application you are working on. You can use this list to determine which type of camera will best fit the needs for your project.

– Object detection: A monochrome or color camera with a built-in IR sensor

– Image segmentation and tracking: A monochrome or color camera with a built-in IR sensor

– Vision based navigation: A monochrome or color camera with a built-in RGB sensor

– Compound microscope: Monochrome or color cameras that have a 2x digital zoom

Monochrome vs. color cameras

When buying a camera for your machine vision application, the first thing you need to decide is if you want it to be monochrome or color.

Monochrome cameras have a singular color sensor and are designed for use in low-light environments.

Color cameras contain two sensors: a color and a monochrome sensor. They are usually optimized for high-light applications.

The decision of whether to go with monochrome or color comes down to what kind of application you’re working on. If you know that your application will only work well in low-light environments, then monochrome is the way to go. If, however, you’re working on an application where color is critical, then going with a color camera will be more beneficial.

Low light vs. high-light sensors

Most cameras that use machine vision for industrial purposes are low-light sensors. Low light sensors have a long depth of field, which allows you to focus on an object without having to move the camera. This is beneficial because it means you can focus accurately on an object while also noticing other objects in the background.

Low-light sensors also have high sensitivity to infrared light and near-infrared light. Infrared light has a shorter wavelength than visible light, so it’s more sensitive when it comes to capturing images at night or during low-light conditions. Near-infrared lights have a longer wavelength than infrared light, so they’re not as sensitive during nighttime or low-light situations.

However, if your application requires high resolution data, then you should consider buying a high-light sensor instead of a low-light sensor. High-light sensors are able to capture higher quality images and do not require as much attention as low-light sensors do when processing images. They can also process photos without any sort of illumination from the environment but with only ambient light from the camera itself. Check for more right here.

How to choose camera vendors.

When choosing a camera vendor, you need to determine what type of camera will best meet your needs. This can be done through careful consideration of your application, budget and company size.

First, analysis of the application will help you identify the specific types of cameras needed for your application. For example, if you’re working on an autonomous vehicle that requires low-light vision, a monochrome camera would be necessary. On the other hand, if you’re developing a high-speed sports imaging system with high pixel count, color cameras would fit the bill.

Next, decide how much money you want to spend on it. Do you want to buy one or more cameras? If so, what’s the difference in cost? What are the benefits and drawbacks of each type?

Finally, think about the company size and volume of orders. What’s your budget for this purchase? Will this be a small volume or mass order? How many people will be involved in making decisions about this purchase?
