摘要:
Homography-based imaging apparatus and method are provided. The apparatus may include a processor (44) coupled to process respective sequences of sky images respectively acquired by physical image acquisition devices 181 and 182 at respective spaced apart locations (e.g., P1, P2). The processor may include an image alignment module (32) configured to spatially relate respective views of at least one object (e.g., clouds, aerial vehicles) visible in the respective sequences of the sky images based on homography (42) of at least one astronomical image acquired at each spaced apart location. The astronomical image may include a number of spatial references corresponding to respective astronomical body positions located practically at infinity relative to a respective distance between the spaced apart locations. Further views (synthetic views) may be generated at selectable new locations (e.g., P3, P4, P5, P6), without actually having any physical image acquisition devices at such selectable locations.

An apparatus and method, as may be used for predicting solar irradiance variation, are provided. The apparatus may include a solar irradiance predictor processor (10) configured to process a sequence of images (e.g., sky images). The irradiance predictor processor may include a cloud classifier module (18) configured to classify respective pixels of an image of a cloud to indicate a solar irradiance-passing characteristic of at least a portion of the cloud. A cloud motion predictor (22) may be configured to predict motion of the cloud over a time horizon. An event predictor (24) may be configured to predict over the time horizon occurrence of a solar obscuration event. The prediction of the solar obscuration event may be based on the predicted motion of the cloud. The event predictor may include an irradiance variation prediction for the obscuration event based on the solar irradiance-passing characteristic of the cloud.

A method for detecting and tracking a target includes detecting the target using a plurality of feature cues, fusing the plurality of feature cues to form a set of target hypotheses, tracking the target based on the set of target hypotheses and a scene context analysis, and updating the tracking of the target based on a target motion model.

摘要:
Systems and methods are presented that enable a higher-level software application to query and control a sensor through a generic interface. In one embodiment, a system includes a controller, and interface, and a set of sensor driver modules. The interface receives a command from the controller and sends it to the driver modules. The interface includes a client, a server, and a network. The server includes two interfaces: a client interface to communicate with the client and a driver interface to communicate with the driver modules. The server also includes two buffers: a command queue and a reply queue. The command queue stores commands received from the controller (via the client). The reply queue stores replies received from the driver modules.
摘要:
The present invention discloses a method of brightness correction for the electronic display, which consists of the following steps: take pictures of the electronic display; get the characteristic values of all the light-emitting components in the pictures; calculate the correction values of each light-emitting component with the characteristic values; correct the brightness of the display with the correction values. The present invention reduces the time cost of measuring the actual brightness values of the light-emitting components, and improves the efficiency of correcting the brightness uniformity of the electronic display.
