Problems solved by technology

[0006] However, the encoding capability of the built-in image encoder in the camera has an upper limit limit. When the capture requests generated by manual, timing, and intelligent algorithm trigger methods per second exceed a certain number of frames, the capture control system will ignore the excess capture requests. , resulting in the problem of a large number of capture requests being lost

Embodiment 1

[0029] figure 1 It shows a snapshot control method in Embodiment 1 of the present invention, including the following steps:

[0030] Step S101, receiving a first snapshot request. The first snapshot request is a manual snapshot request or a timing snapshot request.

[0031] Step S102, judging whether the image coding buffer is empty or not. Wherein the image coding cache is used to cache the image corresponding to the first snapshot request.

[0032] Step S103, when the image coding cache is free, move the image corresponding to the first snapshot request to the image coding cache. The transfer is a memory direct access (DMA) transfer.

[0033] Step S104, when the image encoding buffer is not free, ignore the first snapshot request.

[0034] Carry out image capture control according to the above steps, and store the images corresponding to manual capture requests or timing capture requests in the image encoding cache. A large number of capture requests are caused to be l...

Embodiment 2

[0051] figure 2 A snapshot control system according to Embodiment 2 of the present invention is shown, including a snapshot request receiving module 201 , a cache vacancy judgment module 202 , a first handling module 203 , and an ignore snapshot request module 204 .

[0052] The receiving snapshot request module 201 is configured to receive the first snapshot request. The first snapping request is a manual snapping request or a timed snapping request. Corresponds to step S101 in Embodiment 1.

[0053] The buffer empty judgment module 202 is used for judging whether the image encoding buffer is empty. The image encoding cache is used for caching the image corresponding to the first snapshot request. Corresponds to step S102 in Embodiment 1.

[0054] The first moving module 203 is configured to move the image corresponding to the first snapshot request to the image encoding buffer when the image encoding buffer is empty. Corresponds to step S103 in Embodiment 1. The trans...

Embodiment 3

[0073] image 3 A traffic violation capturing device according to Embodiment 3 of the present invention is shown, including a first capturing module 31 , a second capturing module 32 , a capturing control system 33 and an image encoder 34 .

[0074] The first snapping module 31 is configured to generate a first snapping request, and includes a manual snapping unit and a timing snapping unit, the manual snapping unit is configured to generate a manual snapping request, and the timing snapping unit is configured to generate a timing snapping request.

[0075] The second snapshot module 32 is configured to generate a second snapshot request. The second snapping module 32 is an intelligent snapping module, which is used to generate an intelligent snapping request, that is, comprehensively use vehicle detection technology, license plate recognition technology, image processing technology, network communication technology, etc. ask.

[0076] The snapshot control system 33 is the s...

Abstract

The invention relates to a capturing control method, a capturing control system and a capturing device. The capturing control method comprises the following steps that a first capturing request is received; whether an image coding cache is unoccupied or not is judged, wherein the image coding cache is used for caching an image corresponding to the first capturing request; when the image coding cache is unoccupied, the image corresponding to the first capturing request is moved into the image coding cache. Image capturing control is performed according to the steps, and images corresponding to manual capturing requests or timing capturing requests are stored in the image coding cache; even if the images requested to be captured exceed a certain frame number, the exceeding capturing requests will not be ignored directly, and therefore the situation that a lot of capturing requests are lost is avoided. Under the condition that the capturing requests are frequent and random, the capturing requests can be output tending to be smooth; meanwhile, an image encoder can be always in a working state, and therefore the maximum encoding capacity of the image encoder can be brought into play as much as possible.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a capture control method, system and capture device. Background technique [0002] With the development of society and the advancement of science and technology, the traditional transportation system, especially the road transportation system, can no longer meet people's needs. Safety, efficiency and convenience have become the development trend of modern transportation systems. Intelligent transportation system is emerging under such a demand and trend. Various intelligent transportation devices are gradually entering social life, and will greatly improve people's quality of life, promote economic development, and increase social productivity. As an important aspect of intelligent transportation, the traffic violation capture control system is in the stage of vigorous development in China. [0003] In order to adapt to the rapid development of the economy, the construction of ...
