Smart Camera Configuration File

The content, location, and file name of the parameter configuration file can be defined by the user, but the format and parameters must follow the requirements below:

• Configuration file must be in JSON format. Example: /home/aidlux/camera_config.json
• Parameters marked as required or required due to enabled switch parameters must be configured.
• Parameter names (case-sensitive) and types must comply with the requirements in the table below.

Parameter Name	Type	Required	Description
cameraId	string	No	Camera ID. 0: Camera 0 main device, 1: Camera 1 slave device, 2: Camera 2 slave device. Default is Camera 0 if not specified.
triggerWay	int	Yes	Trigger mode. 0: IO trigger, 1: Software trigger (continuous). Example: "triggerWay": 0
rimType	int	No	Edge setting. 0: Rising edge, 1: Falling edge. (Required when triggerWay is 0)
triggerDelay	int	No	Minimum trigger interval (ms). "triggerDelay": 0 means no delay.
debounce	int	No	Debounce interval (ms), required when trigger mode is IO trigger. Example: "debounce": 5
inputChannel	int	No	IO input type. Example: "inputChannel": 1
width	int	Yes	Image width. Example: "width": 1920 or "width": 3840
height	int	Yes	Image height. Example: "height": 1080 or "height": 2160
fps	int		Camera frame rate (fps). Required when auto exposure is disabled. Example: "fps": 60
format	int	Yes	Camera encoding, currently only supports 35. Example: "format": 35
exposureMeteringMode	int	No	Exposure metering mode, 0: disable, 1: enable. Example: "exposureMeteringMode": 1
autoExposure	bool	Yes	Auto exposure setting. true: enable, false: disable. Example: "autoExposure": true
exposureCompensation	float	No	Exposure compensation, required and effective when auto exposure is enabled. Example: "exposureCompensation": 0
exposureTime	long	No	Camera exposure time (us). Required when auto exposure is disabled. Example: "exposureTime": 20000000
sensitivity	int	No	Camera ISO sensitivity. Required when auto exposure is disabled. Example: "sensitivity": 500
autoFocus	bool	Yes	Auto focus. true: enable, false: disable. Example: "autoFocus": false
autoWhiteBalanceMode	int	No	Auto white balance mode, required and effective when custom white balance is disabled. 0: disable, 1: enable. Example: "autoWhiteBalanceMode": 1
autoWhiteBalanceLock	bool	No	Whether auto white balance is locked to latest calculated value, effective when auto white balance is enabled. true: enable lock, false: disable lock. Example: "autoWhiteBalanceLock": false
customWhiteBalanceMode	int	No	Custom white balance mode, required and effective when custom white balance is enabled. 0: disable, 1: enable. Example: "customWhiteBalanceMode": 1
colorCorrectionGains	array	No	Color correction gains (4-element float array), required and effective for RGB gains. Example: [1.0, 1.0, 1.0, 1.0]
colorCorrectionTransform	array	No	Color correction transform (18-element int array). Example: [1, 1, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 1, 1]
colorTemperature	int	No	Color temperature. Example: "colorTemperature": 5500
contrast	int	Yes	Contrast. Range: 0-100. Example: "contrast": 0
sharpness	int	Yes	Sharpness. Range: 0-100. Example: "sharpness": 0
saturation	int	Yes	Saturation. Range: 0-100. Example: "saturation": 0
