How to evaluate the quality of synchronization between event camera and external sensor?
Hello, I'm working on synchronization between IMU and event camera(EVK4). I use hardware trigger to synchronize as documentation says. However, it is hard to evaluate the synchronization quality. A naive way is the compare the data between IMU acceleration
120 degree FOV lens for EVK4 HD
Hello everyone! Does anyone have a recommendation for a good quality, but not overly expensive lens for the EVK4 HD? 120 degree FOV. BR
cannot retrieve biases on SilkyEVCamHD
On a SilkyEVCamHD the reading of bias parameters through the SDK fails. The identical code works for the SilkyEVCamHD: const Metavision::Biases biases = cam_.biases(); Metavision::I_LL_Biases * hw_biases = biases.get_facility(); const auto pmap = hw_biases->get_all_biases();
OnDemandFrameGeneration Segmentation Fault and malloc error
I have run into a problem with the OnDemandFrameGeneration algorithm when encountering high event rates. Currently we are making our own multi-event camera calibration program (to calibrate intrinsics and extrinsics in one pass) and I found the OnDemandFrameGeneration
EVK4-HD 事件相机的同步怎么接
您好,如果我想要实现事件相机与RGB相机帧同步,我需要怎么接呢?我有一个主控制器可以给RBG相机发帧同步Tigger,事件相机这一段我是只需要把那个Tigger接5脚就行了吗?他的时钟可以悬空吗?
Where to get Quantum Efficiency for the EKV4-HD chip?
EKV4-HD是否使用GEN4.0芯片?是以下链接吗?还是以下文件?https://support.prophesee.ai/portal/en/kb/articles/gen4-0-qe
Is it possible to invert the polarity of EVK4 sync_out?
We are designing a synchonization circuit for multiple EVK4 cameras. In our test, the fall edge of the sync_out signal (50ns) is much shorter than the rise edge (~200ns). Is it possible to invert the polarity of sync_out signal by setting the api/registers
Consume trigger events using the BaseStage/Cam API
Hi, Just wondering if it is possible to access trigger events using the BaseStage::set_consuming_callback() API. In the docs there is only mention of the HAL API for accessing trigger events. Thanks!
EVK4 Gen4.2 bias settings
Hello, I wonder how to interpret the values "bias_diff_on" and "bias_diff_of" and why it is not possible for our setup with EVK Gen4.2 to set both values to 190 and 190. Metavision3.0 allows us to set only 190 and 140. What is background of that behavior?
EVK1 GEN3.1 VGA - Pins "push pull" or "open-collector"
Hello, We want to synchronize a 2D camera with the trigger of an EVK1 GEN3.1 VGA camera. To do this we use the PIN 0 and 1 of the camera as detailed in the following link: https://support.prophesee.ai/portal/en/kb/articles/trigger-in-out We would like
Min contrast sensitivity of VGA CIS sensor (EVK3-VGA)
Hi! We recently acquired a EVK3-VGA and I have a question about its minimal contrast sensitivity. I am wondering what the minimal contrast sensitivity this sensor could achieve? I found there are different numbers (12% and 25%) in three references (please
What kind of extension USB cable can I use for my evk?
The cable delivered with the camera is too short for my usage but using a longer one is not reliable and my EVK is not always working properly.
