Recently released smallest motorized lens controller which could be suitable to drive advanced lenses. And after a few iterations finally, the SCF4 controller is released. It is time to introduce a new camera module C1_PRO_X18. Specs 5.5~96mm optical zoom (approximately 54.2° to 3.4° horizontal view angle) Motorized Focus, Zoom, Day/Night filter Reference points for precise […]
Read MoreHow to capture 30fps with Kurokesu cameras in David-3D
When talk comes about 3D scanning everybody knows David-3D software. It’s a pity but it lacks trivial camera control options like selecting MJPEG mode and stuck in YUYV uncompressed mode, this limits performance to low frame rate (about 5 fps). David-3D software does not like it and refuses to scan. It was an issue and […]
Read MorePedestrian detection using YOLOv3
Owning a quality camera can be fairly useful by itself. Video stream can provide a lot of information not easily comprehendable by just using various sensors. However, not always there is a human eye to make a sense of it. Therefore, additional algorithms can be implemented to provide a lot of insights automatically. A lot […]
Read MoreHeatmap motion analysis of autonomous robot
I have always wanted to ease my daily life and obtain vacuum robot. Many things were stopping for a while, but finally found a local company which provides demo units so could not resist taking one for a spin. What a good chance to run some computer vision processing algorithms to analyze it! Seen few […]
Read MoreMeasuring minimal and maximal microscope magnification and zoom ratio
Magnification ratio is one of many parameters to describe optical instrument – microscope in this case. Magnification ratio usually comes along with zoom range. These terms are often being misused. In this post I will measure zoom range and magnification ratio of monocular video microscope lens and stereo inspection microscope (Konus #5424) head. Despite being […]
Read MoreAny CS-mount camera deserves autofocus!
I have been working on open-sourced motorized zoom lens for a while. Probably there is no need to mention benefits of having motorized zoom/focus lens on a regular CS type camera. Even greater value comes by having auto-focus capability. This feature is being calculated on host computer and does not consume lot of resources. Many […]
Read MoreExploring and displaying USB video with GraphEdit
GraphEdit is a little known tool distributed with Microsoft Windows Software Development Kit (SDK) and allows exploring camera settings and video rendering filters. A copy of old version (which worked just fine without installing whole SDK) can be found wildly on the internet. Besides ability of tinkering with options it is much more advanced tool […]
