摘要:
This disclosure describes a system and a method for determining statistics of plant populations based on overhead optical measurements. The system may include one or more hardware processors configured by machine-readable instructions to receive output signals provided by one or more remote sensing devices mounted to an overhead platform. The output signals may convey information related to one or more images of a land area where crops are grown. The one or more hardware processors may be configured by machine-readable instructions to distinguish vegetation from background clutter; segregate image regions corresponding to the vegetation from image regions corresponding to the background clutter; and determine a plant count per unit area.

摘要:
A system for processing remotely acquired imagery includes a storage element (316) for receiving first and second sets of imagery data associated metadata defining a first image of a panchromatic image type and a second image of a multi-spectral image type (404). The system also includes a processing element (302) communicatively coupled to the storage element and configured for obtaining a mapping between pixels in the first image and the second image based on the associated metadata (406). The processing element is further configured for generating a third set of imagery data defining a third image of a panchromatic type based on the second set of imagery data (408). The processing element is also configured for generating an alternate mapping for the first and second images based on comparing areas of pixels in the first and third images that are non-corresponding according to the mapping function (426).

A method for processing remotely acquired imagery includes obtaining imagery data defining a first image of a panchromatic image type, the first image having a first spatial resolution, and obtaining imagery data defining a second image of a multi-spectral image type, the second image having a second spatial resolution lower than the first spatial resolution. The method also includes obtaining a mapping function specifying a position of pixels in the first image with respect to pixels in the second image and adapting the mapping function to a high common spatial resolution higher than the second spatial resolution. The method further includes generating a third set of imagery data defining a third image of a panchromatic type based on the first set of imagery data and the adapted mapping function and having the high common spatial resolution and adjusting the mapping function based on a first difference between the first and the third images at the high common spatial resolution.

A system (100) for processing remotely acquired imagery is provided. The system (100) includes a storage element for receiving imagery data defining a first image of a panchromatic image type using a sensor characterized by a panchromatic spectral response curve and a second image of a multi-spectral image type using at least one other sensor characterized by a plurality of multi-spectral response curves associated with a plurality of optical bands. The first image has a first spatial resolution and a first spectral resolution. The second image has a second spatial resolution lower than the first spatial resolution and a second spectral resolution higher than that first spectral resolution. The system (100) also includes a processing element configured for deriving a radiation transfer model based on meta-data associated with one of the first and the second image and for determining a set of spectral weights for down-sampling the second image to the first spectral resolution based on the radiation transfer model and the panchromatic and the multi-spectral response curves.

摘要:
Method and system for creating a fused image from an image pair. The method includes obtaining (204) image data defining a first image of a panchromatic image type and a second image of a multi-spectral image type. The first image has a first spatial resolution and a first spectral resolution. The second image has a second spatial resolution which is lower than the first spatial resolution and a second spectral resolution higher than the first spectral resolution. The first image and the second image are fused (216) to initialize a fused image having the first spatial resolution and the second spectral resolution. A blurring function is used (220) to help form the fused image.
