Problems solved by technology

[0003] In the prior art, the target object in the image can be detected by analyzing the image data collected by the video surveillance equipment, but due to various reasons, the new type of target object cannot be accurately obtained.
For example, during use, the user will modify the appearance of the electric vehicle or use it to carry bulky items. Placing a large volume on the seat board will cause the outer contour of the electric vehicle to be blocked by other objects, which will easily cause the image data collected by the existing video surveillance equipment to miss the detection of the electric vehicle

Embodiment 1

[0032] as attached figure 1 as shown, figure 1 It is a schematic flow chart of an identification method for an electric vehicle in Embodiment 1 of the present invention, and an identification method for an electric vehicle includes the following steps:

[0033] S101. Establish a first recognition model, where the first recognition model is used to recognize a battery car.

[0034] In other words, the first recognition model calculates that there is an electric vehicle in the picture information through image recognition technology; in this embodiment, the recognition model of the preset electric vehicle adopts the VoVNet network structure as the backbone network for training, using The CenterNet algorithm is used as the core algorithm for recognition and detection, and then the Pytorch model that can detect and recognize electric vehicles and human figures is trained on the Pytorch deep learning framework on the PC side; the Pytorch model is converted into a Caffe model suppo...

Embodiment 2

[0078] as attached figure 2 as shown, figure 2 It is a schematic flow chart of an identification method for an electric vehicle in Embodiment 2 of the present invention, and an identification method for an electric vehicle includes the following steps:

[0079] S201. Obtain a first interval, where the first interval is the time required for the target object to pass through the elevator door; determine whether to perform the first analysis according to the first interval.

[0080] In other words, it is judged whether the first interval is smaller than the first threshold, if the elevator works normally, otherwise step S203 is executed. Specifically, the time required for the target object to enter the elevator and completely enter the elevator is recorded by the photoelectric sensor. Since photoelectric sensors are generally installed in existing elevators to detect whether the target object passes through the elevator door, this step can be directly improved on this basis...

Embodiment 3

[0127] Based on the same inventive concept as the identification method of an electric vehicle in the foregoing embodiment 1 or 2, the present invention also provides an identification device for an electric vehicle, such as image 3 As shown, the device includes:

[0128] The first preset unit 11 is used to establish a first identification model, and the first identification model is used to identify the battery car;

[0129] The first acquisition unit 12 is configured to acquire first information, the first information is a plurality of picture information obtained by the monitoring device along the temporal distribution of the target object;

[0130] The first processing unit 13 is configured to perform a first analysis on the first information by using the first recognition model to obtain a first analysis result;

[0131] The second processing unit 14 is configured to perform a second analysis on the first analysis result to obtain a second analysis result; the second an...

Abstract

The invention discloses a method and system for recognizing whether an electric vehicle enters an elevator or not, and belongs to the field of image recognized.The method includes the steps that video data of a target object within preset time are obtained, and a plurality of pictures are compiled along the time sequence; the possibility that the electric vehicle exists in the picture is calculated, and the possibility that the electric vehicle enters the elevator is obtained through weighted average calculation; the process that the electric vehicle enters the elevator can be automatically recognized, manpower is saved, and the recognition effect is high. For the condition that a user modifies the appearance of the electric vehicle or is used for carrying large-size objects, image information in different images is spliced and merged into a new combined image through plane projection transformation, the possibility that the electric vehicle exists in the combined image is calculated, and the recognition accuracy of the electric vehicle is further improved.

Description

technical field [0001] The invention belongs to the field of image recognition, in particular to a method and system for recognizing that an electric vehicle enters an elevator. Background technique [0002] With the popularity of electric bicycles, the problem of community-based management of electric vehicles has become increasingly prominent. It is mainly reflected in the charging safety of electric vehicles. In order to facilitate charging of electric vehicles, many electric vehicle owners will directly ride their electric vehicles home for charging. Under the conditions of existing batteries and charging technology, electric vehicle charging has a certain probability of fire. Once an electric vehicle catches fire, it can spread rapidly in just a few seconds, especially when many people are used to charging while sleeping at night, which is more likely to cause safety accidents and endanger the lives and property of residents. [0003] In the prior art, the target obje...
