Designed for evaluation and rapid prototyping, the ESPROS kit provides a pre-assembled camera system that combines the epc660 CC chip carrier, optical lens assembly, and a set of eight LEDs. Along with the camera system, a BeagleBone Black processor board with 512 megabytes (Mbytes) of RAM and 4 gigabytes (Gbytes) of flash serves as the host controller and application processing resource. ESPROS also provides epc660 eval kit support software that can be downloaded from its website and opened with a password
that can be requested from the company’s local sales office. After gaining access to the software, developers simply run a graphical user interface (GUI) application with one of several provided configuration files to begin operating the camera system. The GUI application also provides control and display windows for setting additional parameters including spatial and temporal filter settings and finally for viewing the results. With minimal effort developers can use the kit to begin capturing depth maps in real time and use them as input to their own applications software.
Enhanced resolution 3D ToF systems A 320 x 240 imager such as the ESPROS epc660 can serve many applications but may lack the resolution required to detect small movements in gesture interfaces or to distinguish small objects without severely restricting the range of interest. For these applications, the availability of ready-made development kits based on 640 x 480 ToF sensors enables developers to quickly prototype high resolution applications.
