The combination of the high resolution 2D color image and high 3D measurement accuracy with an extremely high acquisition speed makes the Chromasens 3DPIXAwave the perfect measuring device for this challenging 3D vision application. The following report presents technical details and achieved results for the 3D BGA inspection tasks employing Chromasens 3DPIXA wave cameras.
This white paper compares the trilinear line-scan camera allPIXA wave with a prism based camera with respect to bulk material inspection. Traditionally, prism-based cameras are often selected over trilinear cameras when it comes to bulk material scanning, as the inherent line-shift of a trilinear camera can only be corrected for when the object scan velocity is known. We demonstrate that this traditional approach is not always necessary if the right trilinear sensor is selected and operated in binning mode to average multiple pixels.
Machine Vision is one of the driving forces of industrial automation. For a long time, it’s been primarily pushed forward by improvements made in 2D image sensing, and for some applications, 2D sensing is still an optimal tool to solve a problem. But the majority of challenges machine vision is facing today has a 3D character. From a well-established metrology up to new applications in smart robotics, 3D sensors serve as a main source of data.
