Ethernet Mode: Broadcast: 200ms 200ms Connected: 200ms 2800m Upgrading: 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 16: Direct Time Of Flight
5.1.1 Direct Time of Flight In the direct time-of-flight measurement method, a discrete pulse is emitted and one or several timers are used to measure the time difference between the emitted pulse and the return echo, based on threshold detection. This time difference can be directly converted to a distance, based on the following equation:... -
Page 17: 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 18: Vzense Tof Principle
5.1.4 Vzense ToF Principle Vzense DCAM800 Lite product principle is based on range-gated imaging ToF solution, and the sensor inside is based on Panasonic CCD sensor MN34906. -
Page 19: Noise Factors
A strong ambient light may affect the accuracy and precision of the depth data, the Vzense DCAM800 Lite is suggested to in user below 50K LUX ambient light. 5.2.2 Multipath Propagation Based on the principle of ToF, Multipath effect may happen when the light reflected more one once. -
Page 20: Scattering Effect
5.2.4 Scattering Effect Scattering light effect is a noise factor to ToF products, it is caused by multiple reflection inside the lens of camera or the cover of camera. To eliminate the scattering light effect, you should: 1. Keep the cover glass of the camera clean; 2. -
