Also I want to use camera through DVP interface (ESP32-S3 support camera). Which pins can be use to connect the camera?
Well I guess that depends on the application..
yes it ‘s for a computer vision application.
Can you explain more about your intended use? Is it just a personal project? What model are you running? Etc.
@wafa_ath and @undefined2001 have worked on similar systems and should be able to walk you through the process
The project is about to detect whether a person is sleeping or not and many others behaviors. Computer vision models with openCV,tensorflow,mediapipe and other libraries will be used.My job is to make a board that will be able to run all the models.Also connectivity is required.That’s why I chose ESP32-S3.
if you want to use CV with Deeplearning or nn, you should take flash, ram and inference time into account.. i could run yolov5 with 4 classes in a esp32-s2 using 96x96x3 images, but it was quite a challenge because of the RAM and processing constrains. My inference time was 350-500ms. but if you want to use bigger images, and recognize objects at differnet scales, that could be quite challenging
In my personal experience using edge impulse is the best way to train and deploy Ml model on esp32 , ( i assume that u are using camera for the detection)
Ow i see that u mention that, i didn’t notice it
Ok dear. By choosing an external flash memory and PSRAM with a good performance, this can improve the performance?
yes I’m using a camera.Ok I will suggest edge impulse to the model developer. I have done a prototype of the project on a raspberry pi.But now we want to make a customized board that satisfy our requirement.
chek this https://github.com/LUXROBO/edgeimpulse-esp32-firmware
Thanks @wafa_ath
By choosing the right memory size can this improve the performance of my system? Or I have to consider choosing another MCU?
@fatogoma18 here’s a blog @daleonpz just published, ironically: https://baremetallics.substack.com/p/running-yolov5-on-a-esp32-microcontroller
I mean there are already some modules like this
it can be found with very good memory like 8mb sram and 16mb flash
also it is easier to implement into your project
Ok. I’ll do some research about this module.Thanks.
when possible ,choose the mcu that already fulfils your requirements, because you avoid the overhead of managing the connection, but as always is cost of HW vs cost of SW development, the more restrictive the hw is the most expensive and risky the SW will be. sadly I cannot give you a concrete answer
