In the diverse market of industrial cameras, pixel count has emerged as a key factor for selection. But what exactly does pixel count represent, and how should we choose the most suitable industrial camera based on its pixels? This article delves into three aspects of pixels in industrial cameras, assisting you in making an informed decision.
First, let's explain what pixels are. Simply put, the pixels of an industrial camera refer to the resolution of its image sensor. The resolution is typically expressed in tens of thousands, millions, or even tens of millions of pixels. A pixel is the smallest unit that composes an image, formed by discrete points captured by the image sensor from light information. Therefore, the number of pixels directly determines the level of detail and clarity in the captured image. In other words, the more pixels, the higher the resolution of the camera, and consequently, the greater the detail and clarity of the image.
So, how do we determine the pixels of an industrial camera? The method is quite straightforward. Take a camera with a resolution of 1280 by 1024, for instance. Multiplying these two numbers approximates to 1.3 million. Therefore, this camera has 1.3 million pixels, meaning that the images it captures are composed of 1.3 million pixel points.
In practical applications, how should we select the pixel count of an industrial camera? For example, if the required image precision is 0.1 mm per pixel and the actual image dimensions are 50 mm by 40 mm, the necessary resolution would be calculated by dividing 50 and 40 by 0.1, resulting in 500 by 400. In this scenario, choosing a camera with 200,000 or 300,000 pixels would suffice.
Finally, by selecting the appropriate pixel count based on specific application needs and budget constraints, you can find the industrial camera that best suits your requirements. If you aim for a pixel precision of 0.01 mm, how many pixels do you think you should choose for the camera? This is a thought-provoking question and an important consideration when selecting an industrial camera.
