Oil and gas exploration in lacustrine mud shale has focused on laminated calcareous lithofacies rich in type I or type II1 organic matter, taking into account the mineralogy and bedding structure, and type and abundance of organic matter. Using the lower third member of the Shahejie Formation, Zhanhua Sag, Jiyang Depression as the target lithology, we applied core description, thin section observations,...
High voltage transmission lines have a clear and necessary straight-line feature, which can be obtained by using the method proposed in this paper to process captured images. Since high voltage transmission lines operate in a complex environment, it not only increases the noise in captured pictures, but also makes it harder to extract the transmission lines due to background interference. In order...
TDOA (Time Difference of Arrival) is an important passive location method which is widely used in modern localization and navigation system. This design use three microphones to collect the sound signal sent by robot, and process the signal with the filtering circuit which designed to produce an accurate rising edge for microcontroller to capture and calculate the time difference of sound arriving...
A visual pallet recognition system based on the accurate color segmentation is proposed. The basic idea is to get the pallet color feature samples from the images in working environment before the autonomous mobile forklift works. Then the algorithms of morphological filtering, Sobel edge detection and Hough transform are used to get the pallet forking side. At last, according to two corners of the...
