Optionally, an at least simple electric map datum is obtained, as training set, comprising:
An at least simple electric map datum is cleaned, using the simple electric map datum after cleaning as instruction
Practice collection.Wherein, data cleansing refers to the data that mistake is drawn in Rejection of samples electronic map data.Use the correct electronics of drafting
Map datum is as training set, the accuracy of the training pattern guaranteed.
Optionally, model training will be being carried out in the default neural network structure of training set input, is obtaining map detection model
Before, the training process of map detection model further include: every simple electric map datum in training set is increased in real time
Strength reason, to be based on obtaining training set progress model training after enhancing processing.Wherein, real time enhancing processing includes but is not limited to:

Bezel locations carry out joint training.Multitask loss function includes that Classification Loss function (Softmax Loss) and frame return damage
It loses function (Smooth L1Loss), is defined as follows:
Wherein: NclsIndicate input sample number in mini-batch, NregIndicate the quantity of anchor (anchor point) position, i
It is the index of anchor in mini-batch;piIt is the probability that the anchor is predicted to be a target;It is in marker samples
Positive sample probability, andIt is a vector, represents the position that RPN predicts the anchor
It sets;For actual position;Positive sample therein refers to test object, negative sample middle finger image background.
It is the Classification Loss of foreground/background:
It is bezel locations loss:
The error situation of map of considering a problem has countless possibility, such as color mistake, contour line mistake, region missing
Deng, therefore, during model training, suggest that network only marks positive sample in the original image of electronic map data using region,
Rather than label negative sample.For example, setting threshold value T=0.7, target of the probability P greater than T is positive sample, and probability P is less than or equal to
The target of T is negative sample, and the target that P is greater than T is only marked in the original image of electronic map data.
The corresponding loss function of map detection model that final training obtains includes generating the loss of ROI and ROI classifying
It for the loss of specific category, that is, determines the corresponding loss in test object region position, and will test object classification and be positive

Loss=Lrpn+Lspe
Wherein:
Lrpn=Lrpn_class+Lrpn_bbox,Lrpn_classIt is the Classification Loss that network is suggested in region, i.e. network by the inspection of proposition
Survey the loss that frame is divided into foreground/background;Lrpn_bboxIt is the bezel locations loss that network is suggested in region;Lspe=Lspe_class+
Lspe_bbox, Lspe_classIt is the Classification Loss that the region of interest of proposition is classified as to specific category;Lspe_bboxIt is to suggest region
The detection block and true frame (frame of the test object marked in training set) that network proposes compare and the bezel locations of calculating
