Embodiment 1

[0033] An embodiment of the present invention provides a trigger mode switching method. figure 1 is a flow chart of a trigger mode switching method according to an embodiment of the present invention, such as figure 1 shown, including:

[0034] Step S102, determining the weather index score according to the radar data sent by the ranging radar;

[0035] Step S104, comparing the weather index score with a preset threshold, and determining the target trigger mode according to the comparison result;

[0036] Step S106, sending an instruction to the camera, wherein the instruction is used to indicate the target trigger mode to the camera and instruct the camera to switch the current trigger mode to the target trigger mode.

[0037] It should be noted that the range-finding radar may be a laser range-finding radar, an ultrasonic range-finding radar, or other range-finding radars that can complete corresponding functions (such as a range-finding function).

[0038] According to the...

Abstract

The invention provides a trigger mode switching method and device. The method comprises the following steps: determining a weather index score according to radar data sent by a ranging radar; comparing the weather index score with a preset threshold, and determining a target trigger mode according to a comparison result; and sending an instruction to a camera, the instruction being used for indicating the target trigger mode to the camera and indicating the camera to switch a current trigger mode to the target trigger mode. According to the invention, the technical problem of low working efficiency of the camera in the prior art is solved, and the working efficiency and snapshot rate of the camera are improved.

Description

technical field [0001] The present invention relates to the field of intelligent transportation, in particular to a trigger mode switching method and device. Background technique [0002] The Intelligent Transportation System (ITS for short) brings convenience to transportation through intelligent equipment. In the intelligent transportation system, a free-flow gantry system is erected on the road section before each entrance and exit of the expressway to realize segmented toll collection, thereby alleviating congestion at provincial border stations and reducing logistics costs. [0003] In the free-flow gantry system, with the help of video capture cameras, the capture of passing vehicles is completed, so improving the capture rate has become an important indicator of the system. In the traditional camera video self-triggering mode, the camera uses an image processing algorithm to calculate whether there is a vehicle passing by in the current field of view. When a vehicle ...
