Vision camera is an important equipment in logistics industry. It helps the warehouse operator to accurately measure items location and weight, which then recommend picking or sorting order using computer vision algorithm. There are several technologies that can be used to build a vision system (eg: CCD, CMOS, laser). And several companies also provide different type of cameras. However, finding a right Vision camera solution Manufacture in Delhi can be tricky.
1.
Focus on the Image Resolution
Camera
feature like image size (pixels), frame rate (Hz/fps), aspect ratio, processing
speed (frame per second) are important but the most important thing to check is
pixel's resolution! For example, suppose that two cameras has the same
resolution and frame rate, but one camera has 20 lines and other has 25 lines.
This means that if you want to read a barcode which is 10mm high, the first
camera will only be able to read 7.5mm barcodes while the second can read 8mm
barcodes! So image resolution matters when it comes to reading barcodes.
2.
Check the Field of View (FoV)
How
big is the objects can be read by your camera? For example, if you have a
conveyor system which could move items to 100mm wide, and you need to read 20mm
barcode over it, you need a camera with at least a 20mm wideFoV.
3.
Check the Pixel Size of a Camera
Pixel
size is also very important because it dictates how small the barcodes can be
read by0 camera. For example, if you have a 25 lines which has 800*600 pixel
resolution with 4μm pixel size , this means that the minimum width required to
read the barcode is 2.5mm, which is not suitable for most application
requirements.
4.
Check Camera's Frame Rate
Frame
rate is also very important because it dictates how fast will the camera be
able to capture images of items during movement. For example, if you have a
conveyor system that could move 100mm/s and the vision system has a frame rate
of 10 fps, this mean that it can capture only 1% of items in total.
5.
Check the Camera's Noise Level and Dynamic Range
Finally,
you need to check camera's noise level and dynamic range . Dynamic range means
the ratio between minimum input signal for an optical system to give a
specified output signal, and maximum input signal for an optical system to give
a specified output signal. For example, if you have a part with small barcode
in bright light condition, the noise level must be very low in order to read
this barcode. Here is the best ways to find the Vision camera solution Manufacture in
Delhi.
