Application of high-speed motion capture industrial camera
In industrial machine vision inspection, there are often projects that need to capture high-speed moving objects, and the images taken by ordinary industrial cameras will appear to affect image quality, such as fluffing, blurring, and distortion, which cannot meet customer project requirements. At this time, performance is required. High industrial cameras to solve similar problems. After more than ten years of industrial camera R & D experience, iJUNCO has continuously strengthened camera performance and strived to improve the problems in practical applications. Next, we will take the high-speed capture function of MV-EM series industrial cameras as an example.
First look at the following two pictures:

Figure (1) MV-EM series industrial camera shooting still objects

Figure (2) MV-EM series industrial camera shooting moving objects
It can be seen from the above two pictures that even when the object is moving at high speed, the picture presented by the industrial camera will not tilt, and the image will not be affected by the high speed movement of the object. However, it is important to note that when shooting images, the appearance of image blur depends on the length of the exposure time and the speed of the object. If the exposure time is too long and the object moves too fast, the image will appear blurred; if the exposure time is short, similar to that when a moving object is frozen in a short time, the image will rarely appear blurred. So how to choose a high-speed snapshot industrial camera, here is a brief explanation for everyone:
1.Color requirements
To capture the color characteristics of an object, a camera with good color reproducibility is required; in general, a black and white camera is used regardless of the color. However, some features to be detected may appear better in color pictures. At this time, you can also consider using a color camera.
2.Exposure time
To meet the object movement speed Vp exposure time Ts
3.Frame rate index
Frame rate, which is the number of images that the camera can capture per second, generally depends on the image size, exposure time, etc., and is an important indicator of the camera. The camera frame rate needs to be able to capture the two pictures with the shortest time interval required by the system, otherwise it may cause frame drop and other phenomena, and miss some products.
The main factors affecting the high-speed capture of industrial cameras are the above-mentioned factors. Others, such as the lens interface and chip size, have almost no reference value. They can be selected in the same way as ordinary cameras. If you currently need an industrial camera and don't know how to choose, please contact iJUNCO engineers to answer your questions in detail.
