[Product] How long will there be a delay between the image generation of the Vzense ToF camera and the acquisition through the SDK?
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.
[Product] Is the light source used by Vzense ToF camera harmful to human body?
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.
[Product] When using Vzense ToF depth camera to measure black, high reflectivity and transparent objects, will the measurement accuracy be affected?
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.
[Product] For Vzense RGB-D cameras (such as DCAM560C and DS77C), are RGB images aligned with depth images?
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.
[Product] Can the lens surface of Vzense's ToF camera be protected by adding a transparent cover plate?
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.
[Product] [DCAM Series] When multiple cameras are used at the same time, will there be mutual interference?
Vzense's DCAM series products provide effective methods to eliminate or reduce the impact of multi machine interference for different use scenarios. Please refer to our application notes for details. Note link: https://cdn.yun.sooce.cn/4/62267/pdf/16355628650517a063f3d88ea3c3d.pdf
