Detailed Description

OpenCV based camera interface.

This class API serves as a simpler wrapper for the cv2 python camera capture interface, which itself is a wrapper for the C++ implementation.

Constructor & Destructor Documentation

__init__()

None __init__	(		self,
			configs = CfgColor(),
			K = None
	)

Constructor for OpenCV2 camera interface.

Parameters

[in]

configs

Settings to apply.

Member Function Documentation

buildFromFile()

def buildFromFile (   configFile )

static

capture()

def capture

(

self

)

Get the next frame.

Parameters

[out]	color_image	The color image
[out]	succ_flag	Success flag of fetching next frame.

captureRGB()

def captureRGB

(

self

)

Snag the next set of RGB.

Captures the color and depth pair as an RGBD image instance. The depth map should be returned in standard units (meters).

Parameters

[out]	data	RGBD image data as an ImageRGBD element.
[out]	flSuccess	Success flag. True = both frames fetched.

display()

def display	(		self,
			image,
			ratio = 0.5,
			window_name = "Color"
	)

get()

def get	(		self,
			key
	)

Get attributes specified by the key

Args:
    key (str):      Choices: [exposure, gain, W_rgb, H_rgb, W_dep, H_dep, depth_scale, K]
Returns:
    value

start()

def start

(

self

)

Start capturing the stream.

Note

Right now the construction does this, which is poor design.

Todo:

Should implement start/stop functionality and capture boolean.

stop()

def stop

(

self

)

Stop capturing the stream.

Note

Right now not implemented.

Todo:

Should implement start/stop functionality and capture boolean.
