413 results about "Bird nest" patented technology

A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere 2 cm (0.79 in) across and 2–3 cm (0.79–1.18 in) high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than 11 m (36 ft) in diameter and stand nearly 5 m (16 ft) tall.

Aerial image-based method for detecting bird nest in power transmission line

The present invention relates to an aerial image-based method for detecting a bird nest in a power transmission line. The method includes the following steps that: a picture database with annotations and labels is constructed; two deep convolutional neural networks are trained separately: an obtained data set is utilized to modify a classification network VGG16, so that two detection networks can be formed, the two detection networks are trained separately, so that a bird nest roughly selected neural network and a bird nest finely selected neural network are obtained, the roughly selected neural network can obtain a bird nest roughly selected region through using a window sliding method in a feature graph, and the roughly selected region is utilized to train the bird nest finely selected neural network, and therefore, an optimal bird nest region can be obtained; and cross-training and fine-tuning are performed on the networks so as to construct a detection model: a cross-training method is adopted to re-train the obtained roughly selected neural network and finely selected neural network, so that the two networks can share the parameters of the first 13 convolutional layers, and the two networks are combined into an end-to-end convolutional neural network, so that the bird nest detection model can be constructed.

Method for detecting bird nests in power transmission line poles based on unmanned plane images

The invention provides a method for detecting bird nests in power transmission line poles based on unmanned plane images, which is method of perceiving and analyzing power transmission line structure features. Firstly, line segments in different directions are extracted from a polling image, a Gestalt perception theory is adopted to merge small interrupted line segments, and the merged line segments are clustered into parallel line sets. Then, the image is divided into 8*4 blocks according to a structural feature (nearly symmetrical intersection feature) of a pole in the image, the quantity statistics of line segments in four different directions in each block is analyzed, and an area where the pole is in the image is detected. The invention provides a bird nest detection method which fuses colors and textures. Firstly, an area of color consistency in an image is obtained by mean-shift cluster segmentation. Then, according to features of an H histogram of a bird nest sample, multiple areas which are most similar to the bird nest sample in the image are selected as candidate areas of a bird nest through a histogram interaction method. Then, three co-occurrence matrix features of entropy and inertia moments and dissimilarity, which can best represent the bird nest, are selected to calculate texture features of the candidate areas of the bird nest. Finally, matching between each candidate area of the bird nest and the bird nest sample texture similarity is carried out to achieve the bird nest detection.
