Scorpion Vision is launching two low cost, high-speed, high resolution machine vision cameras at the PPMA Show 2021 (NEC, Birmingham UK, 28-30 September 2021). They are both characterised by ultra-fast frame rate capabilities at full resolution, but are available at a highly attractive price point.
The 25 Mpixel Hypersen HPS-HSC5K offers frame rates of 150 fps at full resolution, while the 2.2 Mpixel Hypersen HPS-HSC2K offers frame rates of 1490 fps at full resolution. These new cameras are ideally suited to applications where both spatial resolution and speed are critical requirements, including a host of inspection applications on high-speed production lines as well as high-speed process and machinery diagnostics and logistics applications.
The standard C-mount cameras utilise high performance global shutter CMOS sensors with large pixel sizes to reduce noise for high quality imaging. With GenICam and GenTL support, and an easy to install and use SDK, the cameras can readily be integrated into machine vision inspection systems or OEM equipment. A 40 Gigabit Ethernet optical fibre interface is provided for high-speed image data transmission over long distances.
Flexible triggering options are provided for exposure optimisation. These include automatic exposure, external trigger exposure and software trigger exposure. Built-in image processing capabilities include Fixed Pattern Noise denoising, Photo Response Non-Uniformity correction, gamma correction, lens correction, adjustable region of interest (ROI), gain adjustment, horizontal and vertical binning and left/right and up/down mirroring. By reducing the ROI on the sensor, even higher frame rates can be achieved, while still maintaining impressive resolution. For example with the HPS-HSC5K, 240 fps can be achieved at 10 Mpixel resolution and with the HPS-HSC2K, 2971 fps are possible at 1 Mpixel resolution.
Typical high-speed defect inspection applications for these cameras include checking product, packaging and labels. The key areas are verification, measurement and flaw detection. Other applications include reading of 1D and 2D codes and optical character reading and verification. In warehouses and distribution centres, high speed code reading on large boxes with a small barcode requires the use of megapixel cameras to provide the resolution needed since the code occupies just a small part of a large field of view.
High-speed vision systems can also significantly improve the accuracy of diagnostic analysis and maintenance operations in industrial manufacturing applications such as bottling lines, packaging manufacture, food production lines, plastic container manufacture, pharmaceutical packaging, component manufacturing, paper manufacture and printing. Even minimal discrepancies in can cause an entire production line to come to a standstill. Sequences of images of high-speed process machinery mechanisms can be recorded and reviewed, either frame by frame or using slow motion playback both for machine set-up and process monitoring.
