Problems solved by technology
Therefore, the present invention aims at the problem of degradation of detection accuracy caused by low resolution of target features due to occlusion, and proposes a way to decompose the target area into multiple small areas, so that the overall appearance and partial details of the target object can be obtained at the same time. The sampling process can extract the features of all target areas and partial detail areas, thereby improving the target detection accuracy of the model

Embodiment Construction
[0035] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0036] According to a kind of city management business travel behavior detection method described in the embodiment of the present invention, based on detection image area scaling factor and partial / global target feature extraction, comprising the following steps:
[0037] Step 1: Construct a data set N of 20,000 based on cameras in the city management business area, in which the number of training data sets T is 16,000, the number of verification data sets V is 4,000, and the value of learning rate is 0.001. The proportional coefficient α between the set T and the verification data set V is 0.25, and the height h of the image is k = 608,w k =608, r=3 and the height, width, and number of channels of all images are consistent.
[0038] Step 2: Determine the first-stage target detec...

The invention discloses an urban management business touring trade behavior detection method and device and a readable storage medium. The method comprises the following steps: collecting an urban management business image data set, calibrating a touring trade behavior data set in a detection area, and determining a used one-stage target detection algorithm model; constructing a local / global feature joint extraction upsampling layer based on a detection target; correcting an algorithm by a linear function unit; and training a model: carrying out real-time detection and identification on the trained model in urban management business tourist behaviors. The invention has the advantages that partial and global details of the target object are obtained at the same time, more detection target features can be extracted in the up-sampling process, and then the target detection precision of the model is improved.
Description
technical field [0001] The present invention relates to the technical fields of image recognition and computer vision, in particular, to a method, device and readable storage medium for detecting tourist behavior in urban management business. Background technique [0002] In recent years, with the rapid advancement of my country's urbanization process, the number of urban population has increased year by year; at the same time, the scale of itinerant businessmen who make a living on the streets has also further expanded, which has become an important factor affecting the environmental order in urban management, and has also increased the number of "urban diseases". "Difficulty of governance. On the one hand, citizens demand a good city environment and order, but on the other hand, they agree with the convenience brought by unlicensed vendors. As an important department of urban management, urban management and law enforcement have spent a lot of manpower and material resourc...
