Can I able to customize color camera node's sensor resolution value?

thrada

I know there is 3 members (1080p, 4k, 12mp) can set to sensor resolution. Can I customize this resolution value? (like (2000, 1500) or (1000, 750))

Hello thrada, yes, you can. There are several outputs from the ColorCamera node - raw, isp, video, still, preview. For example, you can set the preview size of the colorCamera with camRgb.setPreviewSize(300,300) or video size with camRgb.setVideoSize(1000, 750). You can choose the size that you need, you just have to make sure it's not higher than the sensor resolution (so for 1080P you can go up to 1920x1080, for higher sizes you would have to change sensor resolution to 4k).
Thanks, Erik

Thanks for reply @erik . I'm sorry but your information is not exactly what I want to know. I mean it was able to change the attribute of the SensorResolution in dai::ColorCameraProperties. I want to know I can change this because when I see preview through opencv in size (1920, 1080), 1080p sensor resolution looks noisy then 12MP resolution.

thrada sorry, I thought you meant if you can change the size of the actual image (like 2000x1500 or 1000x750). You can change both the resolution of the actual sensor and the output size of the preview/video/isp outputs.
To change the resolution of the sensor, eg. to 4k:
camRgb.setResolution(dai.ColorCameraProperties.SensorResolution.THE_4_K)
And in the previous reply, there's code to change the size of preview/video frames.
THanks, Erik

@erik I understand that setResolution function parameter receive the value of ColorCamerProperties enum value.
Can I do like this?:
camRgb.setResolution((2000, 1500)) or camRgb.setResolution((1000, 750))

erik

thrada no, but you can set the video size to 2000x1500 after setting sensor resolution to 4k.

camRgb.setResolution(dai.ColorCameraProperties.SensorResolution.THE_4_K)
camRgb.setVideoSize(2000, 1500)

The video output frames will now be 2000x1500, which I assume is what you would like to achieve.
