Abstract

The invention discloses a laser detection apparatus with scenario identifying function, comprising a laser detection apparatus and a scenario identifying device mounted on the laser detection apparatus. The scenario identifying device comprises a pre-treatment module for images, an image extreme point detection module, an image characteristic point positioning module, a principal direction determining module and a characteristics extracting module and a scenario determining module. The image characteristic point positioning module determines the extreme points of characteristics points by sorting out the low contrast ratio points sensitive to noises and the unstable marginal points. The principal direction determining module connects any two adjacent peak values in the histograms of oriented gradients for the characteristic points to form a plurality of sub-line sections wherein adjacent sub-line sections with similar gradients are consolidated in the length direction to form line sections. The direction of the most optimal one of the line sections is regarded as the principal direction of the characteristic points. According to the invention, high identifying accuracy for scenarios and high speed can be achieved.

Description

technical field [0001] The invention relates to the field of laser detection, in particular to a laser detection device with a scene recognition function. Background technique [0002] The determination of the scene plays an important role for the machine to exert its maximum efficiency. If the laser detection device can determine the scene it is in and select the corresponding mode for detection, the efficiency will be greatly improved. However, the current laser detection device does not have a scene judgment 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 a laser detection device with a scene recognition function. [0004] The object of the present invention adopts following technical scheme to realize: [0005] Provided is a laser detection device with a scene recognition function ...
