Don't prioritize aperture, because you can make up for low aperture with controlled lighting conditions to illuminate your object of interest.Notice the parallax effect on the normal lens. Normal (left) vs telecentric (right) lens. This means avoiding optical distortion (no wide-angle or fisheye lens) and sometimes using a telecentric lens for small FoV, high precision applications.In industrial vision, accuracy for the application is key. In photography, lens and sensors are optimized to capture "pretty" images in a variety of lighting conditions. Key tip: Good photography setup ≠ good industrial vision setup. Use the right lens, camera, and lighting setup All-in-one - is the camera system an all-in-one package (or does it require a separate frame-grabber).Stereoscopy - does it support stereoscopic vision (usually one master camera communicates with one slave camera).Image quality - does it have enough resolution for your FoV.Framerate - does it have enough framerate for your application.Compatibility - does it have GigE vision or use some other standard.When scoping out a high speed camera, there are a few important metrics to consider: We ultimately down-selected on using a high-speed computer vision system with stereoscopic setup because it can precisely track both trajectory and rotation. For example, a radar setup is used in baseball stadiums. Putter and ball markers are captured by a high speed camera, the marker movements are converted to object trajectory and velocity, then plotted in a GUI The Project HardwareĬomputer vision is not the only way to track ball trajectory. Who: I was lead hardware developer and programmer working with 3 project members. In order to design putters that minimize slip, our sponsor required a measurement system to quantify the effectiveness of their putter prototypes. The less a ball slips, the less it will deviate from its desired straight path. Why: In golf putting, the accuracy of a putt is highly dependent by how quickly the ball reaches pure roll (non-slip condition) after it is putted. We used two industrial high speed cameras in a stereoscopic setup with MATLAB for back and frontend programming. What: Developed a hardware-software system for tracking and plotting the trajectory of a golf ball in 3D space during putting.
