Abstract
The invention provides an ultrasonic detecting device with a scene identification function. The ultrasonic detecting device comprises an ultrasonic detecting device and a scene identification device which is mounted on the ultrasonic detecting device. The scene identification device comprises an image pretreatment module, an image extreme point detecting module, an image characteristic point positioning module, a main direction determining module, a characteristic extracting module and a scene determining module, wherein the image characteristic point positioning module determines extreme points as the characteristic points through eliminating low-contrast points which are sensitive to noise and instable edge points. The main direction determining module is used for drawing a line between two random adjacent peak values in a histogram of oriented gradient related with the characteristic points for forming a plurality of sub-line-segments, combining the sub-line-segments which have approximate gradients and are adjacent in a length direction for forming one line segment, and utilizing the direction of the optimal line segment in a plurality of line segments as the main direction of the characteristic points. The ultrasonic detecting device has advantages of high scene identification precision and high speed.
Description
technical field [0001] The invention relates to the field of ultrasonic detection, in particular to an ultrasonic detection device with a scene recognition function. Background technique [0002] The determination of the scene plays an important role for any machine to exert its maximum efficiency. If the ultrasonic detection device can determine the scene it is in and select the corresponding mode for detection, the efficiency will be greatly improved. However, current ultrasonic detection devices do not have a scene determination function. In addition, in order to process large-scale image data, it is necessary to improve analysis processing efficiency and accuracy. Contents of the invention [0003] In view of the above problems, the present invention provides an ultrasonic detection device with a scene recognition function. [0004] The object of the present invention adopts following technical scheme to realize: [0005] Provided is an ultrasonic detection device w...
