The invention relates to rapid visual orientation and remote
monitoring system and method based on an embedded
mobile robot. The
system mainly comprises an embedded base plate, an
embedded core plate, an image
data collecting module, a
digital signal processing module, a
network communication module, a storage module, a
USB interface and a terminal device. The
embedded core plate collects image information by the image
data collecting module, forwards the image information to the
digital signal processing module, rapidly extracts key characteristic points of the images according to improved SIFT (
Scale Invariant Feature Transform)
algorithm and compares the key characteristic points with the image
characteristic point information of the special marker stored in the storage module so as to identify the images, further determine the position of the
mobile robot according to coordinates of the special marker and complete visual orientation of the
mobile robot. After determining the position of the marker, the
digital signal processing module sends the positioning information through a communication module to the terminal device. The
system is compact and reliable in structure, and can rapidly and effectively identify the special marker during remote orientation of the mobile
robot which is oblique, deformed, dirty, partially sheltered and has a complicated background and changing light.
