Compile errors in Tensorflow Lite Micro framework when trying to integrate Tensorflow Lite Micro to my ESP32 Arduino project

Asked 2022-Apr-05 at 03:13

Hi stackoverflow community,

I am trying to get a project leveraging Tensorflow Lite Micro to run on my ESP32 using PlatformIO and the Arduino framework (not ESP-IDF). Basically, I followed the guide in this medium post https://towardsdatascience.com/tensorflow-meet-the-esp32-3ac36d7f32c7 and then included everything in my already existing ESP32 project.

My project was compiling fine prior to the integration of Tensorflow Lite Micro but since integrating it, I am getting the following compile errors which seem to be related to the Tensorflow framework itself. When I uncomment everything related to Tensorflow, it compiles fine. But just when only including the following header files, it breaks:

I resolved this for now by switching from the Arduino framework to the ESP-IDF framework. With this, it works like a charm.

You need to understand what you are doing before doing anything.

You are using the ESP32 HTTP Server API. Have you checked its documentation? It even has an example program.

Now, you have registered a handler for some URI. It probably looks something like this? :) (Or perhaps you changed the uri.)

Unable to save right jpg format picture taken from ESP32Cam module and it does not open in Windows

Asked 2021-Sep-23 at 07:24

Tried to save the picture taken from ESP32Cam module, into SD Card as JPG file but it fail to open in Windows.

I have followed the code to take picture as is present at the below link: https://github.com/espressif/esp32-camera/blob/6a9497bbe909165663d958986e621e98dabcf994/examples/main/take_picture.c

After taking the picture I am converting it to jpg file using "frame2jpg". The camera used is OV2640. After conversion I am saving as.jpg file in SD Card. The SD card I moved to Windows PC and tried to open the saved .jpg file, but it does not open. It gives a message that file in not recognized.

Do I need to do more than just "frame2jpg" to convert it in right format?
[EDIT]: Moved "esp_camera_fb_return" after fclose.

Great, now the problem is much easier to debug. The data in the file is missing the JPEG header (ff d8 ff e0 00 10 4a 46 ...) so it's probably the raw image data. If you look a the documentation for frame2jpg() it shows that the buffer cnv_buf will receive the JPEG image. That, however, is not what you're writing to the file. You're writing the original, unconverted frame with raw data:

Reassign variable of type auto that is currently std::unique_ptr

Asked 2020-Nov-22 at 22:57

I am currently experimenting with the ESP32-CAM, which is a microcontroller with integrated camera that you can program through the Arduino IDE (with C++11). For capturing images with the cam, there is a library called 'esp32cam', which contains the function esp32cam::capture(). This function apparently returns a variable with the type std::unique_ptr. There is also an example sketch, which saves the returned frame in a local variable of the type auto:

QUESTION

How to send images from ESP32 CAM to IoT Core?

Asked 2020-Oct-18 at 19:31

I need the system to be secure.

I tired to encode the image with base64 and sending the string via MQTT to Iot Core. Then decode the string with a cloud function and finally storage the decoded image in Google Cloud Storage. The problem is the limited size of a message in MQTT.

Using a Cloud Function and then storage in Google Cloud Storage is not really secure, anyone could hit that url and I loos control of all the ESP32CAM comunication.

Am I missing something? is there a really secure way to send files to Google Cloud Storage from to IoT Core?

Thanks

...

ANSWER

Answered 2020-Sep-29 at 17:27

IoT Core should not be used to transfer big blobs.

However, you can take advantage of the secure connection between IoT Core and the device to send credentials to the device to access GCS securely.

Create a service account with write only access to your GCS bucket. Pass a key for that service account to the device through IoT Core(via configuration change, for example) The device then can use that key to connect securely to GCS and upload the image.

Depending on your preferences and the particular use case you can rotate the keys to access GCS whenever you want, or be as granular as you want with the permissions (one key for all the devices, one key per device, ...)
