ifm develops 3D cameras, based on pmd ToF imagers, for industrial applications. These cameras are characterized by their robust, stable point clouds, repeatable measurements in all environments and flexibility in software interface. If takes advantage of the scalability of the pmd ToF technology by offering two hardware platforms with variations in housing size, range, field of view and cost.
O3D Hardware Platform
The O3D is the “flagship” hardware platform from ifm. Based on the 352 x 288 (100k) pixel imager, the O3D platform calculates the full point cloud onboard through the use of a quad core Imx6 processor. This processor is also available to the user for the calculation of custom algorithms deployed on the camera (via an OEM partition). For more technical details see the O3D camera data sheet.
The key features of the O3D platform are:
|Imager||FoV||Range||Accuracy at 2m
|352 x 288||40 x 30, 60 x 45, 70 x 54||0.5 - 8m||+/- 7mm||IR LEDs (4)||Onboard||Onboard||24V DC||Ethernet||72 x 65 x 83|
|224 x 172||60 x 45||0.5 - 3m||+/- 20mm||Vertical Cavity Side Emitting Laser (VCSEL) (1)||Onboard||Offboard||24V DC||Ethernet||80 x 44 x 21|
Part of our software philosphy is to reduce the level of friction between connecting to the hardware and receiving the point cloud data in the host PC. To this end, all ifm industrial cameras communicate via Ethernet and support both Windows and Linux operating systems. Interfaces and code examples for C++, Python and ROS are also readily available for download from ifm Github. As well as a point cloud visualization tool, called Vision Assistant.
