Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as figure 1 As shown, an embodiment of the present invention proposes a method for traffic camera capture control, including the following steps:

[0031] Step S100, obtaining the mains AC signal of the same power source as the signal light;

[0032] The AC signal of the mains is obtained by connecting with the mains. Since the power of the mains and the signal light are the same, the AC signal of the mains has the same phase and period as the signal light.

[0033] Step S200, photoelectrically isolate the AC signal to generate a synchronization signal, and obtain the phase of the sig...

Abstract

The invention relates to a method and device for snapshot control of a traffic camera. The method comprises the following steps of: obtaining an alternating current signal having the same power supply with a signal light; carrying out photoelectric isolation on the alternating current signal to produce a synchronous signal so as to obtain a signal light phase; and triggering the camera at the set phase according to the synchronous signal for snapshot. With the adoption of the method and device, the condition that signal light blackout and yellowing occur in pictures of rule-violating events shot by the camera when a stroboscopic signal light is used is eliminated.

Description

technical field [0001] The invention relates to the technical field of signal control, in particular to a method and device for traffic camera capture control. Background technique [0002] At present, with the development of science and technology and the improvement of people's awareness of green and energy-saving, out of energy-saving considerations, traffic lights on the streets and alleys are gradually using low-energy traffic lights that flash frequently. Correspondingly, if the original camera equipment is not replaced However, the captured illegal images cannot prove that the illegal vehicle was running a red light at that time, because the red light at that time was in the cycle of red light off or red light dark during the capture period, so the image is not enough to serve as qualified evidence for traffic electronic police. Therefore, it is the purpose of the present invention to control the snapshot camera device to activate the shutter to capture the snapshot w...
