Certain to open new opportunities for 3D applications, the dual-view band-limited illumination profilometry (BLIP) with temporally interlaced acquisition (TIA) system or simply BLIP-TIA, relies upon the BitFlow Cyton-CXP CoaXPress frame grabber to transmit images from two CMOS cameras to a computer for processing at rates surpassing 12.5 Gb/S.Įxisting 3D systems based on the widely used technique of Fringe Projection Profilometry (FPP) have two main limitations. July 20, 2021 - Research scientists with the Energy Materials Telecommunications Center, National Institute for Scientific Research in Quebec, Canada, have developed a groundbreaking technique 1 to acquire 3D images at over 1000 frames per second with resolution as high as 1180 x 860-far beyond the capabilities of available systems today-by eliminating information redundancy in data acquisition. BitFlow CoaXPress Frame Grabber Used in Groundbreaking New 3D Imaging System Either one camera with 4 channels, 2 cameras with 2 channels or 4 cameras with one channel each can be operated directly on a 4-channel frame grabber.Research scientists with the Energy Materials Telecommunications Center, National Institute for Scientific Research in Quebec, Canada, have developed a groundbreaking technique to acquire 3D images at over 1000 frames per second with resolution as high as 1180 x 860-far beyond the capabilities of available systems today-by eliminating information redundancy in data acquisition. This allows using several cameras on one grabber. Multi-Camera: CoaXPress interface offers the possibility of multi-camera control.All setting parameters can be controlled directly via the frame grabber’s GenICam explorer. Plug and Play: The camera communicates directly with the frame grabber via the standard GeniCam, therefore no SDK or control software is required for the camera.However, if you compare the price/Gbit/s, the overall costs is more favorable. Costs: Prices for a CoaXPress setup are somewhat more expensive than systems that use standard interfaces available in the PC due to the additional component of the frame grabber.There is a wide product range with many suppliers (>50) in the area of cameras, cables, frame grabbers and repeaters. Usage: Since CoaXPress was published as an official standard in 2011, the interface has become established and is widely used in the high-end machine vision sector.Pre-Processing: Many frame grabbers offer the possibility to perform calculations directly on the grabber in real time (laser line extraction, blob, compression, etc.) which leads to faster results and accelerates image processing.This means that processor is available for subsequent image processing. Processor load and Grabber: The advantage of using frame grabbers is the minimal process load on the PC system data transfer from the grabber to PC memory is direct via DMA.The local power supply is not necessary which simplifies installation. Power supply: The camera can be powered directly via the CoaXPress interface.The interface is therefore real-time capable, making it ideal for industrial automation applications. This is necessary for accurate synchronization of multiple cameras and is used for synchronization with illumination or data acquisition systems. The trigger jitter is practically negligible. Both data transmission and triggering are performed with constant delay times (latency). Triggering and real-time capability: CoaXPress offers very accurate triggering capabilities over the same line as image data are transfer.Fiber repeaters are optionally available for longer cable lengths. Cable length: Lengths of 40 m and more cover most in machine vision applications. This corresponds, for example, to a transfer of 280 images/s with 16 MPixel resolution. With the latest version 2.0 (CXP-12), data transfer rates of 50 Gbit/s are possible.
