Abstract
Provided is a method for three-dimensional imaging a plant in an indoor agricultural environment having an ambient light power spectrum that differs from a power spectrum of natural outdoor light. The method comprises directing a spatially separated stereo pair of cameras at a scene including the plant, illuminating the scene with a non-uniform pattern provided by a light projector utilizing light in a frequency band having a lower than average ambient intensity in the indoor agricultural environment, filtering light entering image sensors of each of the cameras with filters which selectively pass light in the frequency band utilized by the light projector, capturing an image of the scene with each of the cameras to obtain first and second camera images, and generating a depth map including a depth value corresponding to each pixel in the first camera image.
