Photonfocus has two new GigE video cameras for high-speed, 3D triangulation used in conjunction with a line laser:
- The MV1-D2048x1088-3D06-760-G2 based on a CMOSIS CMV2000 CMOS V3 image sensor has a triangulation rate of 42fps for a 2048x1088-pixel image but narrow its programmable region of interest to 2048x11 pixels and its triangulation rate jumps to 18619fps. (Previously discussed in Xcell Daily—see “Photonfocus’ new laser-triangulation video camera gets real-time performance from on-board Spartan-6 FPGA.”)
- The MV1-D1280-L01-3D05-1280-G2 based on a LUXIMA LUX1310 image sensor has a triangulation rate of 948fps for a 1280x1024-pixel image but narrow its programmable region of interest to 768x16 pixels and its triangulation rate jumps to a blindingly fast 68,800fps.
Photonfocus’ MV1-D1280-L01-3D05-1280-G2 high-speed 3D camera operates at triangulation rates as fast as 68,800fps
As you might expect, the high-speed interface and processing requirements for the sensors in these two 3D-imaging cameras differ significantly, which is why both of these cameras, like other cameras in Photonfocus’ MV1 product line, are based on a Xilinx Spartan-6 LX75T FPGA. As discussed in the prior blog post last September, use of the Spartan-6 FPGA permits Photonfocus to use an extremely flexible and programmable, real-time, vision-processing platform that serves as a foundation for many different types of cameras with very different imaging sensors and very different sensor interfaces—all operating at high speed.
