1 General Information The purpose of this document is to familiarize the customer with the correct operation of the Vzense ToF Camera. This document provides important information about the camera’s features, hardware specification, safe use of the camera, and installation procedures. -
Page 4: Description And Features
Description and Features Vzense TOF RGBD Camera Module DCAM305 is a 3D camera module developed by Vzense which uses TOF (Time of Flight) technology for face application scenarios or short distance scenarios. It is packaged in a small form factor and can provide high- precision depth information to be widely used for face-related applications such as financial payment, access control, gates, smart lock, time attendance terminal, etc. -

Page 13: Principle Of Time Of Flight
5 Principle of Time of Flight Scope of remote sensing technology · Presence or proximity detection, where the absence or presence of an object in a general area is the only information that is required (e.g., for security applications). This is the simplest form of remote sensing; ·... -
Page 14: Range-Gated Imaging Tof
The difficulty in implementing the direct time-of-flight measurement method resides in the time intervals to be measured. In order to resolve a distance to centimeter-level accuracy, the required accuracy for the timers is 67 ps. Implemented in digital logic, this would require a 15 GHz clock speed, which is obviously not practical. Therefore, various time-to-digital conversion methods are typically used. -
Page 15: Continuous Waveform Tof
By measuring the energy received in successive integration intervals, it is possible to extrapolate the distance between the sensor and the measured object, based on the ratio of energy received in the different intervals. The difficulty with range-gated imaging is that CCD and CMOS imagers have a limited dynamic range;... -

One range mode of the Zense DCAM305 camera can fulfill furthest distance be at most 5 times of nearest distance. For example, if the near limitation is 0.4m, then the furthest distance in this mode can reach about 2m.
