IMX477 camera board for motorized zoom lenses

With the introduction of motorized zoom lenses, the next logical step was matching the sensor board. Sure there are countless suitable sensors from various manufacturers like Sony semiconductors, Onsemi, Aptina, and many more. But lack of good support from the SOC side suggested starting from IMX477. It is a reasonably modern 12M image sensor used […]

Until now, filters were bare glass elements intended to be mounted during camera assembly or in case of camera rework kits installed with double-sided tape. For Kurokesu cameras, this was a somewhat limiting factor for a customer to change a […]

Camera body cap update for CS and M12 cameras

While good at protecting from dust, camera body caps are rarely used with industrial cameras. After the camera is unpacked and the lens is installed usually it stays this way for a very long time. And even if lenses are switched over, the camera very rarely stays with an unmounted lens. Adhesive Polyamide tape is […]

Cooking C2 camera for science

C1 PRO camera was known for surviving fairly high temperatures. New C2 was designed with better heat management in mind thus the picture is still usable at 100*C (aluminum enclosure) temperature. Keep in mind that this is not a full-featured test in the thermal chamber, both cameras were cooked on 200W preheat the oven. But I was pretty happy […]

Pulling full resolution from a webcam with OpenCV (Windows)

OpenCV while being the most popular tool for a lot of machine vision applications it relies on a third party and some poorly maintained code. Capturing MJPEG compressed video from a UVC USB camera was always the case and it did not work or worked with some issues. This situation is especially bad for Windows OS. […]

Measure linear rail quality with camera and excel

No matter how precise and rigid your mechanical system is, it will always have some imperfections. These imperfections can be measured and described. If measurements show opposite it means your measurement tools are not precise enough or you are doing it wrong. There are a lot of expensive and highly specialized tools to measure every […]

UVC camera exposure timing in OpenCV

USB cameras can have the exposure set to manual (cheaper ones have only full auto mode). It’s a pretty straight forward function in OpenCV, but insufficiently documented thus hard to find exact times and calculations. Also there are two major implementations for Linux and Windows. Linux – exposure times are set in units 1/s (all […]
