1 General Information The purpose of this document is to familiarize the customer with the correct operation of the Zense ToF Camera. This document provides important information about the camera’s features, hardware specification, safe use of the camera, and installation procedures. DCAM710 camera is a standalone ToF module, developed by Vzense team. It is packaged into small factor and a perfect choice for evaluation or study to the ToF technology.
1.2 Description and Features VZense TOF RGBD Camera Module DCAM710 is a long range depth camera that outputs depth video stream. In addition to depth video stream, it can provide RGB video streams. The small size of the DCAM710 subassembly provides system integrators flexibility to design into a wide range of products. The DCAM710 is ideal for system integrators, OEMs, ODM and HVM. Perfect for indoor/outdoor usage with long range depth sensing, e.g.
2 Precautions 2.1 Safe Usage Instructions DANGER Electric Shock Risk Non-standard and improper power supplies may result in fire and electric shock. You must confirm the camera power supply used that meets the Safety Extra Low Voltage(SELV) and Limited Power Supply (LPS) requirements. CAUTION Invisible Radiation This camera uses laser to work, improper use may damage the eye.
Do store the camera carefully when not in use, in original package the best. 2.4 Temperature To avoid damaging the camera and to achieve best performance, please observe the maximum and minimum housing temperatures in Section 3.1 3 Specifications and Requirement 3.

3.4 Working Condition Requirements 3.4.1 Hardware Requirements DCAM710 ToF Camera Micro USB Cable (Included in package) If you need to user your own micro USB cable for some reason, make sure the cable itself can meet the USB standard requirement, otherwise the product may not function well. Or 5V~6V/2A DC Adaptor (Not included in package) 3.4.2 Software Requirements Operating system 32-bit Windows 7/10 64-bit Windows 7/10 (recommended) Linux (x86, x64) Android 5.
3.4.4 Coordinate of the Camera System There are two coordinate system need to be understood, one is camera coordinate system (CCS), one is world coordinate system (WCS). CCS: CCS describe the two-dimensional data, the origin of coordinates is the optic center. WCS: WCS describe the three-dimensional information. The CCS data can switch to the WCS data using the camera internal parameters. X Y Fig.

5 Principle of Time of Flight 5.1 Vzense ToF Principle Vzense DCAM710 product principle is based on range-gated imaging ToF solution, and the sensor inside is based on Panasonic CCD sensor MN34906. Fig. 9 5.2 Noise Factors 5.2.1 Ambient Light Because the ToF distance measurement relies on the reflection of light sent out by the camera, any additional light, e.g. artificial light sources or sunlight, may influence the measurement results.
To eliminate the multipath effect, you should: 1. Keep the camera working environment as clean as possible; 2. Avoid the camera be placed at concave forms environment, like corners of a room or inside of a narrow space; 3. Highly-reflective object shall be removed far away from the measurement target; 5.
6 Installation 6.2 Hardware Installation You have read and understood the warnings listed under "Precautions" on Chapter 2; To achieve reliable distance measurements, please follow below tips: Better not using the camera in strong sunlight. If have to, keep the ambient light below 50k Lux. Do NOT place any objects in the scene that are not part of your intended target, especially mirrors or other shiny surfaces/objects. Maintain a stable housing temperature during operation.
6.3 Software Installation 6.3.1 Operating system - Windows 7/8/10 Linux ArmLinux Android 6.3.2 VZense SDK and VZenseUtool VZense SDK is available for above systems. Download SDK from below link: China：https://gitee.com/Vzense Oversea：https://github.com/Vzense 6.3.3 Graphic Tool on windows Vense uTool is a graphic tool on windows OS for the all Vzense ToF products.

7 Features 5.1 Slave Trigger Mode At slave trigger mode, the DCAM710 product outputs image only when trigger signal happens. A customized 5pin USB cable shall be in use to implement the slave trigger mode for DCAM710. Hardware Trigger Function Hardware trigger mode is available only when the camera works at slave mode, in slave mode the camera will wait for the hardware trigger signal on Ext_Trigger.
Please refer to the Vzense_ConfigTool_User_Guide.pdf. The slave trigger mode can be used to implement multiple products synchronization, one works as master, the other works as slave. Please refer to Multiple_ToF_Products_Synchronization_Application_Note.pdf for more information. 7.2 Range Customization By default, there are 3 different range modes calibrated for DCAM710, please see below table for more information: Range number Distance range Range 0 0.35m~1.5m Range 1 0.5m~2.8m Range 2 0.8m~4.
Wide dynamic range means that the camera can work at more than one range modes alternately, then the camera itself will combine the result into one depth frame, therefore can expand the range limitation from furthest distance to nearest distance. However the frame rate will be reduced. DISTANCE ERROR % Merge More Modes Into One 4 3.5 3 2.5 2 1.5 1 0.5 0 DISTANCE RANGE UNIT MM Please refer to Vzense_WDR_function_application_note.pdf for the WDR implementation steps. 7.
7.5 IR Image Besides the depth image, Zense DCAM710 camera can also output a VGA resolution IR image. And the IR image is exactly timing synchronized with the depth image. Pixel to pixel mapping is also exactly aligned.
