Embodiment 1

[0025] figure 1 It is a structural block diagram of the first embodiment of the driving record big data auxiliary analysis system shown according to the present invention, and the system includes:

[0026] The information notification device, embedded in the rearview mirror, is used to display the reminder text related to the detour reminder when receiving the abnormal signal of the manhole cover;

[0027] The information notification device is also used to display reminder text related to normal driving when receiving the normal signal of the manhole cover;

[0028] The driving recorder is arranged behind the front windshield, and is used to perform driving recording operations on the front of the front windshield to obtain the current recording frame;

[0029] A data division device, connected to the driving recorder, is used to perform averaging block processing on the received current recording frame, so as to obtain corresponding block images;

[0030] A dynamic process...

Embodiment 2

[0037] figure 2 It is a structural block diagram of the second embodiment of the driving record big data auxiliary analysis system shown according to the present invention.

[0038] Such as figure 2 As shown, in the driving record big data auxiliary analysis system, it also includes:

[0039] A ratio determination device, connected to the dynamic processing device, is used to identify the aspect ratio of the received dynamic processing image, and the aspect ratio includes 3:2, 4:3 and 16:9.

Abstract

The invention relates to a driving record big data auxiliary analysis system. The system comprises brightness recognition equipment which is used for taking a pixel point, with a brightness value in apreset manhole cover brightness range, in a customized processing image as a manhole cover pixel point, and taking a pixel point, with a brightness value out of the preset manhole cover brightness range, in a processed image as a non-manhole-cover pixel point; and data analysis equipment which is used for obtaining each depth-of-field value of each manhole cover pixel point and sending the manhole cover abnormal signal when the mean square error of each depth-of-field value exceeds a limit, otherwise, sending the manhole cover normal signal. The manhole cover pixel point of which the distances to other manhole cover pixel points exceed the limit are used as an isolated manhole cover pixel points to calculate the discharge mean square error. The driving record big data auxiliary analysis system is simple and convenient in calculation and reliable in data. Due to the fact that the abnormal state of the manhole cover in front of the vehicle is analyzed by means of a hardware platform ofthe automobile data recorder, construction of hardware resources can be omitted while the analysis accuracy is guaranteed.

Description

technical field [0001] The invention relates to the field of driving recorders, in particular to a driving record big data auxiliary analysis system. Background technique [0002] Drive recorder is the instrument of the relevent informations such as image and sound in registration of vehicle traveling way. Driving recording is installed After instrument, the video image and sound of running car overall process can be recorded, evidence can be provided for traffic accident. People who like to travel by car can also use it to record the process of conquering difficulties and obstacles. Video recording while walking while driving, while recording the time, speed, and location in the video, which is quite a "black box". It can also be used at home as a DV to shoot the fun of life, or as a home monitor. You can also do parking monitoring and install a driving recorder at ordinary times. The video data cannot be cut. If you cut it, you will not be able to provide help after the...
