Problems solved by technology
[0012] However, the above method also has certain problems in practical applications, such as: because the supplementary light is always on, it is easy to cause high power consumption, high heat, and easy damage to the supplementary light, thereby affecting the supplementary light effect; Moreover, taking the frame rate of CMOSSensor as 30fps as an example, since the exposure method of Rolling shutter is adopted, the time difference between the readout time at the top and the readout time at the bottom of each frame of image will be the readout time of one frame of image , that is, the time difference T=1 / 30s=33.3ms, the time difference is very large, resulting in a large deformation of the moving object

Embodiment Construction
[0029] In order to make the technical solution of the present invention more clear and understandable, the solution of the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0030] image 3 It is a flowchart of an implementation method embodiment of a high-definition camera in the present invention. Such as image 3 shown, including:
[0031] Step 31: High frame rate CMOS Sensor for image capture.
[0032] The frame rate of the high frame rate CMOS Sensor may be 120fps or 60fps, etc., and which frame rate to use may be determined according to actual needs.
[0033] Step 32: For the captured images, at intervals of consecutive M frames of images, use an auxiliary light source with a certain duty cycle that is turned on to perform full-frame image supplementation on the consecutive N frames of images.
[0034] Both M and N are positive integers, and specific values can be determined according to actual ne...

The invention discloses a method for realizing a high-definition camera and a high-definition camera: a high-frame-rate CMOS Sensor is used to shoot images; The auxiliary light source in the bright state performs full-frame image supplementary light on consecutive N frames of images; where M and N are both positive integers. The solution of the present invention has a better supplementary light effect, and can reduce the deformation of the moving object and reduce the implementation cost.
Description
technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for realizing a high-definition camera and a high-definition camera. Background technique [0002] With the advancement of safe city construction, the intelligent transportation industry is developing rapidly. In the intelligent transportation industry, due to the need to photograph moving objects, such as vehicles, and to identify the characteristic information of moving objects, such as license plates and body colors, Therefore, high demands are placed on traffic smart cameras. [0003] Specifically, requirements for traffic smart cameras can include: [0004] 1) It has the function of instant solidification, so that the deformation of the moving object is as small as possible; [0005] 2) Since the feature information of moving objects needs to be identified, the captured image needs to have better brightness and quality, and accordingly, better supplementa...
