TOFcam-635-S
Installation and Operation Manual
General description
The TOFcam-635-S is a miniaturized and cost-optimized 3D TOF
camera. It is based on the ESPROS proprietary time-of-flight (TOF)
technology using the epc635 chip. The camera controls the illumi-
nation and the imager chip to obtain distance and grayscale
images. The cameras are calibrated to provide accurate 3D depth
information. The depth images are compensated against DRNU
errors, modulation errors, temperature, ambient-light and reflec-
tivity of the scene. Its extremely wide field of view of 120° allows a
variety of new applications e.g. for mobile robotics or entrance
controls.
This document allows a TOFcam-635-S user easily to get the
camera connected and started using a computer. It contains a
description of all features, commands, protocols and interfaces of
the device. This allows to connect the module to integrated
systems. The optional software development kit (SDK) contains the
camera operating system (TOFCOS) with all C++ source codes.
Together with the ESPROS epc635 evaluation kit this is the perfect
environment to develop embedded software or even an application
specific camera.
