Embodiment Construction

[0046] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0047] 1. The structure of the binocular camera

[0048] 1. Overall

[0049] Such as figure 1 , the binocular camera includes a short focal length lens 10, a long focal length lens 11, a short focal length image sensor 20, a long focal length image sensor 21, FPGA3, ARM / DSP4, vehicle detector 5 and flashlight 6;

[0050] Its connection relationship is:

[0051] The short focal length lens 10 and the short focal length image sensor 20 are connected back and forth, and the long focal length lens 11 and the long focal length image sensor 21 are connected front and back;

[0052] The short-focus image sensor 20, the long-focus image sensor 21, the ARM / DSP4, the vehicle detector 5 and the flashlight 6 are respectively connected to the FPGA3.

[0053] How it works:

[0054] The short-focus image sensor 20 and the long-focus image sensor 21 are photosensitive, generate an analog signal aft...

Abstract

The invention discloses a binocular camera capable of simultaneously clearly seeing a plate number and people in car in all day, relating to the field of intelligent traffic road monitoring. The method comprises the following steps of (1) receiving two ways of data from two image sensors; (2) respectively computing an average brightness of two ways of received images to carry out exposure control on the two image sensors independently; (3) after combining the two ways of received data to one way of data, outputting one way of data to an ARM/DSP (Acron RISC Machine/Digital Signal Processor); and (4) judging whether a flashlight needs to be opened after receiving a trigger signal from a vehicle detector, if yes, giving the trigger signal of the flashlight while arranging exposures of the two image sensors to preset values to implement exposure control. According to the binocular camera, the synchronization problem of the two ways of data in the ARM/DSP is prevented, and the synchronization problem of the two image sensors and the flashlight and the matching problem of exposure of the two image sensors and the flashlight are solved.

Description

technical field [0001] The invention relates to the field of intelligent traffic road monitoring, in particular to a binocular camera capable of seeing license plates and people in a car clearly at the same time around the clock. Background technique [0002] In intelligent traffic road monitoring, we not only hope to be able to see the license plate, but also to see the situation of the people in the car, so that we can match the vehicle with the person, and at the same time know the behavior of the people in the car, which has great impact on the driving process. Some violations that may occur in traffic accidents will have obvious supervision and restraint effects, and it will also be able to better identify responsibilities and prevent the phenomenon of topping after a traffic accident. However, the existing monitoring equipment and technology cannot meet this demand well, and most of them can see the license plate clearly but not the personnel in the car. [0003] ...
