Automobile data recorder emergency shooting control method and device

Abstract

The invention discloses the field of man-machine interaction and automobile data recorders, and particularly relates to an automobile data recorder emergency shooting control method and device. The method includes the steps that a motion change state is determined by detecting data change through an acceleration sensor; a human pupil change state is determined through a preview image of a shooting unit; when the motion change state and the human pupil change state meet preset conditions, an automobile data recorder is controlled for shooting. Therefore, the automobile data recorder can be controlled for shooting according to the motion change state and the human pupil change state, the moment for snapshotting emergencies is accurate, the mistaken shooting rate and the missing shooting rate are reduced, emergency snapshotting accuracy is improved, storage space can be saved to a certain extent, frequency of operation of deleting useless video data in the storage space is reduced, and the intelligent degree of the automobile data recorder is improved.

Description

【Technical field】 [0001] The invention relates to the field of human-computer interaction and driving recorder, in particular to a method and device for emergency shooting control of driving recorder. 【Background technique】 [0002] With the increase of daily use of vehicles, the vehicle is equipped with a driving recorder for shooting and recording the driving process of the vehicle as a necessary equipment for driving. For example, it can prevent collisions and deal with traffic accidents. It is equivalent to the black box on the vehicle. Of course, it can also be used to record the scenery along the way; when the user is driving, turn on the camera on the driving recorder, The scenery and / or road condition information along the way can be recorded through the camera. [0003] G-sensors are built-in in existing driving recorders, which can sense the numerical changes of acceleration. Traditional driving recorders include the following methods when shooting and storing vi...

AI Technical Summary

Problems solved by technology

Traditional driving recorders include the following methods when shooting and storing video data: 1. By storing all the videos shot in the whole process, this method requires a large storage space, and the storage space is easy to be full. Important video data may no longer be stored, therefore, it is necessary to frequently clear useless data in the storage space; 2. Use the numerical changes detected by the acceleration sensor to control the triggering of taking photos and / or store the captured video data. This method is due to Using a single condition to control, it is easy to misjudge events, and then cause wrong shooting or wrong storage of video data, as well as missing or missing video data; 3. Manual control triggers shooting and / or storing data, which is cumbersome and easy to miss shooting Or missing video time, and very unsafe
