[0003] However, the existing comparative detection equipment is inconvenient to collect the information of the license plate car, and its collection range is limited, which is not conducive to criminal investigation. Moreover, the collected vehicle image is affected by light, weather, etc., which may cause the image to be edged. Fuzzy and poor imaging quality will affect the effect of comparison in the subsequent comparison, and may even cause errors, which will affect the criminal investigation work

Embodiment
[0027] A detection and early warning method based on multimodal vehicle features, comprising the following steps:
[0028] S1. Establish a video monitoring and capturing system on the road in advance, and use the video monitoring and capturing system to capture the vehicles driving on the road, take pictures of the vehicles, and complete the collection of vehicle information. The video monitoring and capturing system is mainly composed of a monitoring camera and a light source Composed of two parts, the light source should be set near the shooting area of the surveillance camera. When shooting vehicles at night, the light source can improve the shooting effect, so that the surveillance camera can shoot suspicious vehicles more clearly;
[0029] S2, the picture in the step S1 is sent to the computer in the form of data, and the picture is preprocessed by the picture processing software (such as PS, etc.) built in the computer, and the picture is processed by the computer, whic...

The invention discloses a detection and early warning method based on multi-mode vehicle characteristics, which comprises the following steps: S1, establishing a video monitoring snapshot system on aroad in advance, snapshotting vehicles running on the road through the video monitoring snapshot system, and shooting pictures of the vehicles to complete the collection of vehicle information; S 2, transmitting the image obtained in the step S1 to a computer in a data mode, and preprocessing the image through image processing software built in the computer; S 3, firstly constructing an experimentsystem; then, transmitting the picture preprocessed in the step S2 to an experiment system; enabling the experiment system to collect vehicle information in the picture. By means of the video monitoring snapshot system, information collection can be directly conducted on vehicles running on the road, the collection range is widened. Images are processed through the image preprocessing system. Definition of the images is improved. The effect of comparing the characteristics of the vehicles subsequently is improved, and the possibility of errors is reduced.
Description
technical field [0001] The invention relates to the technical field of vehicle feature detection, in particular to a detection and early warning method based on multi-modal vehicle features. Background technique [0002] In public security cases, the vehicle in the video is a clue that is often used to solve the case. However, it may be that the vehicle often uses a fake license plate, which requires identification of the vehicle, especially a fake license plate. When camouflaging a car with a license plate, it is generally necessary to identify the main features of the vehicle, and the main features of the vehicle include body color, license plate number, etc. The existing comparison detection equipment can collect and compare the main features of the vehicle to complete the matching. Identification of license plates. [0003] However, the existing comparative detection equipment is inconvenient to collect the information of the license plate car, and its collection range ...
