There is an upgrade driver in the upgrade tool. If the driver is not installed, this problem will occur. After the driver is successfully installed, the flash back problem will be solved.

Whether for UTool used by DCAM series or NebulaGUI used by DS series, the IR and Depth images saved by both are 16bit image data, which cannot be opened by using the system's own image browser, but can be opened and viewed by using software such as ImageJ; The point cloud map saved by the GUI is in. txt format. From top to bottom, it is the coordinate point information from pixel 0 to the last pixel. The values in each row are the X, Y, Z coordinates of the pixel. The saved point cloud map can be viewed using CloudCompare software. For related instructions, please refer to the link:https://cdn.yun.sooce.cn/4/62267/pdf/16339227552770a0bd9e3dcaf8a6b.pdf

TOF camera calculates the distance from the object to the camera by calculating the time between the light from the camera and the return light from the object received by the camera. Different object surface colors and materials have different reflectivity and absorptivity to light. Therefore, if the measured object is a smooth black object, it may not be recognized. The following methods can be tried: 1. Reduce the product frame rate (for example, 5 frames) and increase the exposure time (for example, 4000); 2. Change the Confidence filter threshold to 2 or 5

DS series does not support parameter configuration such as device output mode, but only supports changing device network mode and IP. If you need to change the camera output mode, frame rate and other parameters, you can call the SDK interface. For specific methods, refer to the SDK development documentation. Change IP tool: https://github.com/Vzense/NebulaGUITool (Including usage documents)

You can upgrade through NebulaGUITool under Windows. The link is: https://github.com/Vzense/NebulaGUITool (Including upgrade firmware and usage documents)

Development language: C/C++, ROS, Python, C # operating system: Windows/Linux/Arm Linux

Vzense Software Development Kit (SDK) supports SDKs of different software platforms and programming languages to help users quickly build and expand customized solutions. SDK download link: https://github.com/Vzense

The default is the distance from the point to the camera plane. You can call interface Ps2_ SetComputeRealDepthCorrectionEnabled: true (the default value) represents the distance from the point to the camera plane; False represents the distance from the point to the camera point.

The SDK does not directly provide samples of color point clouds with RGB mapping. Call can be completed according to the following process: 1. Set VZ_ SetTransformColorImgToDepthSensorEnabled to Enable; 2. Obtain VzTransformedColorFrame image and point cloud generated by depth; 3. Save the VzTransformedColorFrame and point cloud obtained in 2 as a xyzrgb point cloud file.

The above errors are generally caused by the user downloading and unzipping the SDK on a Windows computer, and then copying the unzipped file to the Linux system. Please copy the downloaded SDK package directly to the Linux system, unzip it on the Linux system, and then run it.

Yes, set up via interface Ps2_ SetWaitTimeOfReadNextFrame. Please refer to the SDK documentation for specific steps.

Ps2_ ReadNextFrame is used to query the SDK image ready. If there is no ready, it will sleep and wait. If the image cannot be obtained during the default waiting time, it will timeout and exit. The default timeout is 350ms. However, if the user uses the slave trigger mode, because the trigger frequency is uncertain, when the frequency exceeds the default timeout, the user will also receive a read timeout, but the use will not be affected.

Windows: C:\Users\xxxx\AppData\Local\Vzense\Log Linux:  /home/.config/Vzense/Log

Yes. Users can use GUI tools to adjust and set the switches of various processing effects according to the instructions, determine the required processing effects or parameters according to their own project needs, and adjust the module default values through various interfaces in the SDK.

First, ensure that the downloaded Nebula SDK is unzipped under the Linux system, and do not copy it for use after unzipping in the Windows system; Secondly, ensure that all files in the lib folder (including the config file) are copied to your own project files.

The image captured by the ToF camera can maintain high stability when the light changes, which is one of the reasons why many users choose the ToF camera. To understand the performance of Vzense ToF camera outdoors, you can view this video: https://youtu.be/SWUsVR0-I54

For batch requirements, Vzense can deeply customize 3D ToF modules in terms of appearance design, size and structure, use distance, view angle, interface protocol and operating system SDK. According to different customization requirements, the development cycle varies. Generally, it takes 2-3 months for prototype samples, and it takes a total of 5-6 months for products to reach the mass production stage.

The stability of the module will not be affected when the environment temperature is not higher than the temperature marked on each product. It is recommended that the limiting service temperature should not exceed - 20 ℃~60 ℃. All types of camera products have been tested for high and low temperature reliability. If it needs to be used in extreme high temperature environment, it is recommended to add external heat dissipation design, such as heat sink or fan, which will protect the mold from long-time operation.

Multipath interference will occur in the corners of right angles, the light from the camera will reflect back and forth in the corners, so it looks like there will be radian.

Rainy environment will affect the measurement accuracy of the camera, so it is not recommended to use it in rain. For several cameras meeting IP67 standard, the camera will not be damaged in rainy environment.

The delay of Vzense ToF cameras of different models will be different due to different transmission interfaces and host performance, and the range is about 50~100ms. The user can test the platform by using the soft trigger mode.

The total power of VCSEL device used in Vzense ToF camera does not exceed 2W. The product has passed the FDA Class 1 eye safety level certification, and will not cause harm to human body.

When using DCAM Series to measure black, high reflectivity and transparent objects, the reflectivity of the object surface is too high/low, which will interfere with the reflection light path to a certain extent, resulting in reduced accuracy or even inability to image. But for DS Series, this problem has been solved by the HDR mode added. In addition, when the ToF depth camera is measuring objects, if the light path in front of the lens is blocked, the measurement accuracy will also be reduced.

Yes. Before the standard Vzense RGB-D camera leaves the factory, the internal and external parameters have been calibrated. The output RGB image and the depth image have been aligned on the camera's internal processor. At the same time, the interface for users to align themselves has been opened. After the user gets the camera, he can view the alignment effect between RGB and depth map through the GUI. There are two alignment effects for viewing: RGB pixel points correspond to depth image pixel points, and depth image pixel points correspond to RGB pixel points.

No.The product body has been equipped with a protective cover plate. If you have additional requirements for the hardness of the cover plate, you can contact us for customization. The maximum hardness can reach 9H. If the user adds a cover plate by himself/herself, it will interfere with the optical path of the ToF module, which will greatly affect the imaging quality and accuracy of the module.
