Hi,

would be nice to have a method to set the % of the flash light to avoid too much light in case of a closer object to void reflections

I want to turn on the flash when the esp32cam captures the image so that the lighting is good, how do I do that?

Great example on using the camera itself to conveniently get training data.

On your example, you mention that "In fact, you can well capture images at the resolution you prefer (up to the RAM limits, of course) and still have space to run FOMO model.".

When doing capture with a modified camera.resolution.face() to say .vga(), the capture interface only seems to be saving the a portion of the streamed image(s). Seems to crop on the top right corner to what I assume is the default resolution of .face()

I couldn't find methods to modify this, so I thought i'd ask you first.

Hello, I have have an ESP32-CAM / AI Thinker - at least I thinker it is. The board is marked ESP32-S and executes examples of AI Thinker code correctly including camera server. I have installed library 2.7.6 in Arduino IDE 1.8.13. Attempting to compile "Take a picture" example I get the following compile error:
c:\users\steve\documents\arduino\libraries\eloquentesp32cam-2.7.6\src\eloquent_esp32cam\camera\camera.h:77:32: error: 'struct camera_config_t' has no member named 'pin_sccb_scl'
config.pin_sccb_scl = pinout.pins.sccb_scl;

Attempting to compile "Save picture to SD card" I get the following error:
no matching function for call to 'Eloquent::Extra::Esp32::Wifi::Sta::connect()'

I like the simplicity of the code - it is 90% of my desired application (all that remains is ftp to my website). Any thoughts would be appreciated.

I'm running release v1.1.2 on an m5stack timer cam board. Using example code 3_Get_Your_First_Picture.ino, the system frequently crashes and reboots with error messages like:

hi there,

Is your feature request related to a problem? Please describe.
i can successfully compile and upload the example for object detection. but the camera does not initialize, therefore my camera cannot perform object detection. instead, i get this error in the logs:

Describe the solution you'd like
the camera should initialize during setup().

Describe alternatives you've considered

Dear All,

I'm trying to use AITHinker esp32-cam but it looks like it's not working because of missing memory. Here is the error, do I have any chance to make it work?

The Daemon that runs motion detection as a separate RTOS task cannot be stopped after calling .start(). It would be good to provide .stop() and .pause() methods that would allow the task to delete itself or to be paused.

In my application I want to use motion detection at low resolution and then switch to taking a few high resolution pics once triggered and reverting back to low-res motion detection later. I will adapt your Your Motion_Detection_Higher_Resolution example for now but ultimately it would be better to run the motion detection as a separate task using your Daemon feature and to be able to pause motion detection temporarily while taking a set of high-res pics to ensure the detected object is properly captured at least once.

Following this tutorial https://eloquentarduino.com/posts/esp32-cam-object-detection
I installed the eloquent library and found the example code for Collect_Images_for_EdgeImpulse
Tried compiling and found ./xclk.h was not found.

Hi @eloquentarduino, sorry, I'm not an expert in C programming, nor in ESP32, no more in using github; however I have a question:

I want to make a cam project which stream video on demand and take a photo with the motion detection feature.
Before taking a very long time to try to understand how I could make both jobs on a single code, I can see 2 deposits that propose video streaming and motion detection: this deposit EloquentEsp32cam and this one: https://github.com/eloquentarduino/EloquentSurveillance
As they are quite different.... Why keeping both on github? Which one should I better use (the simplest)?

Thanks,

This is a variant of motion detection to meet a different requirement. Motion detection detects significant differences between successive frames from the camera. In the event of an object moving into the field of view and staying there for some while motion detection will produce a signal at the start and end of the period while anomaly detection will produce a signal for the entire period that the object is in the field of view regardless of whether it moves around or not.

This requires the library to have a reference image against which to do the moving points comparison. The reference image could be either:

1. captured explicitly on request from the client app or
2. the most recent image that did not trigger anomaly detection.

Option 1 would suit a production line environment where lighting is consistent
Option 2 would suit an outdoor environment where lighting varies slowly through the day

Option 2 would require an additional moving point ratio to be set which would be the (lower) threshold below which the reference image can be replaced. Any images above the lower threshold but below the trigger threshold would be ignored.
This lower threshold could potentially be learned during a training window feature where the maximum moving point ratio between images over a period of time is captured but that is probably a step too far for the library.

Hello i would like be able to stream the mjpeg image but after making this operation on the image channel components.
Blue - Red / Blue + Red. Could this be done with the eloquent library which looks so straight forward? thank you for your feedback

when trying to run the face detection example, is this because a library update?

Dear friends
By choosing "Motion detection" program on Arduino 1.8.9, I face an error :
C:\Users\--\Documents\Arduino\libraries\EloquentEsp32cam\src/eloquent_esp32cam/motion/detection.h:4:24: fatal error: dl_image.hpp: No such file or directory
so what's the problem ?!

Hi, which ESP32 Arduino development version should I use?

Currently, I'm using ESP32 Arduino (from Espressif) version 2.0.11 and I get a compile error when I compile examples. I guess I'm using the wrong version of ESP32 development platform.

Motion_Detection.ino: 28:7: error: expected nested-name-specifier before 'void

Thank you.

I keep getting this error when loading the 25 example.

Any ideas what I am doing wrong?

is there anywhere example on how to use filebrowser with files from sd card? Thanks!

Hello
Thank you for your good library.
I need more explanation about determining Rio's parameters in square mode.
Most of the coordinate determination is what I want. Are the X and Y points defined based on the bottom left?
What are the maximum width and length values?
I would be grateful if you could give more details.
Also in circular mode.
Sincerely

First time doing a request / issue. Hopefully this is the place

Can you add support for the M5 Stack ESP32 PSRAM Timer Camera X (OV3660)
SKU: U082-X. the camera pins are -->. https://github.com/m5stack/TimerCam-arduino/blob/master/src/camera_pins.h

Also as a new user to the 'EloquentEsp32cam' library -- examples "3_Get_Your_First_Picture.ino" I am not sure what "m5" references --- in the allowed values -- can a comment be added since M5 has about 5 esp32 cam variations
* Allowed values are:
* - aithinker()
* - m5(). <<<<--- need documentation on what this is?
* - m5wide()
* - eye()
* - wrover()
*/

Hi @eloquentarduino,

there is a compilation issue with the code related to the camera module. i fixed it and created this pull request

kind regards,
rey malahay

Arduino IDE 1.8.19
EloquentEsp32cam 2.0.5

Seems inconsistency in file names.
To work around I changed all .h to lowercase letters in camera and viz folder.

Hi there,

I am looking into detecting movement and found the elequent library, which is using the get_moving_point_number() (from /include/image/dl_image.hpp)

The Function is very well explained, but I don't seem to find where the source code is. Can someone point me into the right direction?

Thank you in advance

If you try to use the library in its current state, it will throw out and error about a file not detected (most likely XCLK.h or Brownout.h) thats because in "camera.h" most header file names are wrong, so i fixed this issue, to use my fix replace all "#include"s in "/src/eloquent_esp32cam/camera/camera.h" with these:

#include <esp_camera.h>
#include "./quality.h"
#include "./Brownout.h"
#include "./XCLK.h"
#include "./Resolution.h"
#include "./Pinout.h"
#include "./Sensor.h"
#include "./pixformat.h"
#include "./rgb_565.h"
#include "../extra/exception.h"
#include "../extra/time/rate_limit.h"
#include "../extra/esp32/multiprocessing/mutex.h"

then save the file and compile and it should compile without any errors!

for some reason the github is only updated to version 1.1.2 but in the arduino library manager its up to 2.2.0, this fix only works with the 2.2.0 that you can only get from arduino as far as i know

Not a bug but a question.

I tried this but it seems to have no effect:

    camera.sensor.vflip(1);
    camera.sensor.hflip(1);

What am I doing wrong ?
