Embodiment two:
In order to be clearer to understand the object detection method provided by the above embodiment based on regression algorithm, the embodiment of the present invention
It is illustrated in conjunction with concrete application.
There is the image of Bird's Nest to be used as training set firstly, sorting out 164 from existing unmanned plane inspection photo, wherein 18
Opening has the image of Bird's Nest to be used as verifying collection, and 60 images are used as test set, wherein not having Bird's Nest in 2 images.
By the geometric transformation of image, enhance technology using one or more of data splitting to increase input data
Amount:
(1) rotation or reflection transformation (Rotation/reflection): by image Random-Rotation unspecified angle;Change figure
As the direction of content;
(2) turning-over changed (flip): along horizontal or vertical direction flipped image;
(3) scale transformation (zoom): zoom in or out image according to a certain percentage;
(4) translation transformation (shift): image is translated in a certain way on the image plane;It can be used random
Or artificially defined mode specifies range of translation and translating step, direction carries out translation change picture material horizontally or vertically
Position;
(5) it change of scale (scale): to image according to specified scale factor, zooms in or out;Or it combines special
Sign is extracted, and using specified scale factor to image filtering tectonic scale space, changes the size or fog-level of picture material;
(6) contrast variation (contrast): in the hsv color space of image, change saturation degree S and V luminance component, protect
Hold that tone H is constant, the S and V component to each pixel carry out exponent arithmetic, and exponential factor increases illumination and become between 0.25 to 4
Change;
(7) noise disturbance (noise): random perturbation is carried out to each pixel RGB of image, common noise pattern is green pepper
Salt noise and Gaussian noise;
(8) colour switching (color): PCA is carried out in the RGB color of training set pixel value, obtains the 3 of rgb space
A principal direction vector p1, p2, p3;And 3 eigenvalue λs 1, λ 2, λ 3.
In the present embodiment, using by 90,180,270 degree of stranded image rotation of method, increase by 3 times of sample set.
In the present embodiment, detection specific steps are carried out to target are as follows:
(1) regional choice.This step is positioned to the position of target.Since target possibly is present at any of image
Position, and the size of target, Aspect Ratio are not known yet, so the strategy of original adoption sliding window carries out entire image
Traversal, needs to be arranged different scales, different length-width ratios.Although the strategy of this exhaustion contains that target is all to be likely to occur
Position, but disadvantage is also evident from: time complexity is too high, and it is too many to generate redundancy window, seriously affects subsequent characteristics and mentions
The speed and performance for taking and classifying.The length-width ratio of actually due to by time complexity the problem of, sliding window is typically all
Fixed setting is several, so for the biggish multi-class target detection of length-width ratio floating, even sliding window is traversed also not
It can obtain good region.
(2) feature extraction.Due to the Morphological Diversity of target, illumination variation diversity, the factors such as background diversity make
It is not so easy for designing the feature of a robust, however the quality for extracting feature directly influences the accuracy of classification.This
A stage common feature has SIFT, HOG etc..
(3) classifier.The classifier that conventional target detection uses mainly has SVM, Adaboost etc..
Referring to Fig. 2 and Fig. 3, respectively the original image schematic diagram in sample database and the figure after image procossing
As schematic diagram, due to the image as sample set be derived from different places have different illumination conditions, different resolution ratio with
And different size etc., the characteristic of image are not quite similar.If raw video picture is directly sent into convolutional neural networks,
It certainly will influence whether feature extraction, or even influence the result of target detection.Therefore, neural network is input in image carry out convolution
Before operation, corresponding, effective processing is done to image, can achieve the effect for improving testing result accuracy.At present more
Common image processing method has image gray processing, binaryzation, normalization and data enhancing.
Binaryzation: color image captured by camera has tri- color channels of RGB, each pixel is corresponding with three
Value of a value between [0,255].And so-called gray processing is by the value in three channels by distributing different weights and being added,
It is set only to replace the value of original three color channels with a resulting brightness value is added.And binaryzation is then in gray processing
On the basis of image, by the way that corresponding threshold value is arranged, gray value is divided into two kinds and assigns 0 or 255 two value again.
Normalization: image normalization is that image is changed into system by the means of processing variation to treated image
The image of one form, such as can be uniform sizes by the skimble-scamble image normalization of size of different unmanned plane shootings is derived from.
The method helps speed up the pace of learning of neural network, makes its more rapid convergence.It can determine in an experiment depending on trained convergent
It is fixed whether need using.
Data enhancing: being used as support since deep learning needs huge sample size, otherwise may be due to training
Sample size is insufficient and the phenomenon that over-fitting occurs.Therefore, in order to avoid the generation of this phenomenon, in order to improve being applicable in for training result
Property, need to using concentrate limited image to be stretched original sample, overturn, mirror image, displacement etc. data enhancing method, from
And achieve the purpose that exptended sample collection.Customized data enhancement methods, such as random change background picture also can be used simultaneously
The method of element, partial region in selective erasing image, and use the method for noise filling, realization to the global information feature of image into
Row study, enhances robustness.
Referring to fig. 4, to be a kind of by gridding treated image schematic diagram, here, by the way that object detection task is turned
It changes a regression problem into, greatly accelerates the speed of detection, it can 45 images of processing per second.And since each network is pre-
Full figure information is used when surveying target window, so that false detection rate is greatly reduced.Specifically, including:
(1) input picture is obtained, divides an image into the grid of 7*7 first;
(2) for each grid, 2 frames are all predicted, including each frame be target confidence level and each frame
Probability of the region in multiple classifications;
(3) 7*7*2 target window can be predicted according to previous step, it is relatively low then to remove possibility according to threshold value
Target window removes redundancy window finally by NMS (Non-Maximum Suppression, non-maxima suppression).
Here it is possible to see that whole process is very simple, does not need intermediate candidate region (RegionProposal) and exist
Target is looked for, the judgement for just completing position and classification is directly returned.
