Camera Block¶
How this block appears in a Simulink model?¶
What can be configured?¶
| Configuration Parameter | Selectable Option/Value | Description |
|---|---|---|
| Stream mode | to Aimagin Connect--to Matlab--to Target | Select whether the camera feed should be streamed to Aimagin Connect, to Matlab Simulink or to Target ESP32. |
| Camera Module | AIMAGIN Camera--Custom Camera | Select the camera module. |
| Camera Pins | Enter the camera pin connections. | |
| XCLK frequency (Hz) | Enter the clock frequency | |
| LEDC TIMER | Enter the LEDC TIMER | |
| LEDC CHANNEL | Enter the LEDC CHANNEL | |
| Image Format | RGB565--YUV422--GRAYSCALE--JPEG--RGB888--RAW--RGB444--RGB555 | Select the image format. |
| Frame Size | QQVGA--QCIF--HQVGA--QVGA--CIF--VGA--SVGA--XGA--SXGA--UXGA--QXGA | Select the frame size of the camera feed. |
| JPEG quality | 0 to 63 | Enter the required quality of the image. |
| Number of frame buffers to be allocated | Enter the number of buffer frames to be allocated. | |
| Sample time (sec) | -1 (inherited) or specify | Specify the sample time |
When to use this block?¶
This block can be used to stream the camera feed to,- To Aimagin Connect.
- To Matlab Simulink.
- To the target ESP32.
How does this block work?¶
- Mode: to Aimagin Connect
A webapp should be created using Aimagin Connect website. Then the exported web-app should be transferred to the SD card connected to the ESP32.
- Mode: to Matlab Simulink
In order to stream to Matlab Simulink, ‘esp32_camerablock_receiver’ and ‘esp32_host_setup’ blocks should be used in the model file at the target computer.
- Mode: to Target ESP32
In this mode the camera feed can be processed within the ESP32 itself by enabling output ports in the esp32_camerablock.
Demo¶
Reference¶
This block is based on the esp32-camera driver by Espressif.
