6.What problems are you experiencing?
Excuse me, i’m having another problem for my camera module, when i’m tried on raspistill command the image is clear and no error, when i tried Python3 1_test.py the image RGB is all green, and i can’t calibrate the chessboard because the green image error, is that because of the camera or the program ? thank you
7.What attempts at troubleshooting have you already made?

raspistill uses half-combine, 1_test.py (it uses MIPI_Camera SDK) supports full-combine but it does not go through ISP, so the image appears green.
If you want better image quality, you can use picamera to get the image, but it cannot get the full-view image. (I will provide a ROS example in the attachment)
If you want full-combine, you need to use stereo_depth_demo (MIPI_Camera SDK), but the calibration procedure in stereo_depth_demo is not very good, and it may take multiple attempts. You can try to calibrate with a small number of pictures, for example, 10.
The sample program I sent you uses picamera to get images, and the image quality should be the same as raspistill.
This sample program is a node of ROS, you can unzip the zip file, there is a README that describes how to install and use it.
@wong now i have another question about full-combine, so i already install the SDK Library, and followed the example, but i have error about this, what does it means and what should i do ?
sorry @wong my problem about full-combine camera was already fixed, and now back to this problem, so can you give me solution, can i still use IMX219 module instead of the pi camera for depth mapping ? need your reply ASAP thank you
The codes in these two links give you a reference how to turn on software white balance.
You should be able to see how software_auto_white_balance is used when you open these two links:
camera.software_auto_white_balance(enable = True)
