Efficiently replaying sync data from sync camera
Dear community, Thank you for reading. I am currently working with two EVK4 camera synchronized with the sync module of the SDK. I recorded some synchronized raw and I wanted to play it back real-time, and still synchronized. I cannot use the sync module
IMX636 Bias Values for Automotive Driving Scences
Hello, I am planning to use the EVK4 with the IMX636 sensor in recording of an automotive dataset. Are there any existing experiences or recommendations regarding bias adjustment for driving scenes or outdoor environments? If not, what would be the best
Use the trigger interface to collect, and open the collected RAW files with metasion software. There is a freeze on the screen. How can I eliminate it? Thank you!
External trigger source 1MZ, logic analyzer test results RAW file trigger information 3、When opening RAW files through METAVISON software, the screen keeps getting stuck, and the effect is as shown in the attachment. 4.problem 4.1. Want to know how to
Extrinsic Calibration of the Camera
Hello, I need to convert the units of measurements from pixel to meter and from pixel/sec to m/s that are the output of this code https://docs.prophesee.ai/stable/samples/modules/cv/sparse_flow_py.html?highlight=sparse For doing that, I need to calibrate
Pulse signal stopping problem during master-slave camera synchronization
Hello, I would like to ask you about the stop pulse signal: experiment procedure: 1. First synchronization: After compiling SDK: metavision_hal_sync, start the slave first and then the host. There is no problem with synchronization. Note: The USB data
Using Prophesee camera for paint thickness estimation
Hello, I want to use the Prophesee camera, EVK4, for estimating the paint thickness while spraying. Is this possible to measure the size and velocity of the tiny paint particles using your camera? Is there any code or instruction that I can use? Thank
Where to get EVK4's Sensor Characterization?
Hi, Prophesee! Now I have an EVK4, but Sensor Characterization need to know, such as latency, shot noise rate, threshold and etc. In this link, https://support.prophesee.ai/portal/en/kb/prophesee-1/metavision-sensing/sensors, I found the documents of

Transfer Latency / DMA burst transfer
Hi all, We are experiencing higher latencies under low event-rates (~4ms). I am pretty sure, that the main factor is the DMA burst transfer latency (https://support.prophesee.ai/portal/en/kb/articles/evk-latency ) I have a few questions: 1. Can I change
Using GenX320 Kria Starter kit with Ubuntu
We are developing an SNN accelerator using the Programmable Logic of the Kria KV260. This is designed to be used with the official Xilinx Ubuntu image and we want to integrate this with GENX320 starter kit. As a first step, we just want to get the example
KV260 Login Failure After Flashing Linux Image
Hello Prophesee Team, I am currently flashing a Linux image onto the KV260, following the official tutorial. The image file I used was downloaded from the following link (click "Download Links--Linux image" in the link and get access to the image file):
Building Prophesee genx320 camera drivers on Jetson Nano
Hi, I have a Prophesee genx320 starter kit, It builds and works fine with Raspi5. However, i would like to build on Jetson Nano. Is there any possible way for doing it? Thanks
Low pixel latency for bright LED
We were attempting to measure the Glass-to-glass latency of our Event camera system and noticed an interesting phenomenon. Experimental setup: We generate a timed event by flashing an LED and we also feed the electrical signal into the the external trigger
