Description

Drive recorder

Technical field

The utility model has related to a kind of drive recorder, the especially a kind of drive recorder that can analyze the space.

Background technology

The bicycle register has been released since the market, can make in detail video recording to the road conditions in the driving process, and in conjunction with GPS track record driving path and the speed of a motor vehicle, also can be in conjunction with gravity sensor detecting driving shaking degree.But existing drive recorder can not clearly be presented on its video file carrying out track and the speed of a motor vehicle, the place that occurs unusual acceleration of gravity in the driving process can not be marked at video file.

The utility model content

Technical problem to be solved in the utility model provides drive recorder, can show in real time GPS track and the speed of a motor vehicle in the driving process in conjunction with the video recording picture, and shows the three axles vibrations variation of video recording broadcast point with the image change of multidimensional.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:

A kind of drive recorder, comprise the CPU processor, also comprise the gps data receiver, image sensor and the gravity sensor that are connected with described CPU processor, also be connected with SD memory card and display on the described CPU processor, be connected with the internal memory output module between described CPU processor and the display.

The utlity model has following beneficial effect:

1, driving recorder cooperates the broadcast of video file, and the longitude and latitude that utilizes the gps data receiver to record changes, and draws synchronously the GPS track of playing when time point on video file, allows the user know that clearly automobile proceeds to the relevant position of terrestrial coordinates;

2, the velocity variations of utilizing the gps data receiver to record when draw playing when the GPS of time point track, with the place of the broadcast of film, during mark track place of arrival, can show the at that time speed of a motor vehicle more simultaneously, with about arrow mark at that time acceleration and deceleration situation;

When 3, driving recorder cooperates the drafting of the broadcast of video file and track, can show track the road name of process;

4, driving recorder cooperates the broadcast of video file, utilize X, the Y that gravity sensor gathers, the G value of each axle of Z to change shelves, graphic change with multidimensional, when video file is play, draw the G value variation of playing when time point, allow the user open-and-shut know produce wherein unusual change in gravitational acceleration situation.

Fig. 2 is the change in gravitational acceleration synoptic diagram that the utility model kind is used for the drive recorder of spatial analysis.

Embodiment

Below in conjunction with Figure of description, the utility model is further described.

As shown in Figure 1, a kind of drive recorder, comprise the CPU processor, also comprise the gps data receiver, image sensor and the gravity sensor that are connected with described CPU processor, also be connected with SD memory card and display on the described CPU processor, be connected with the internal memory output module between described CPU processor and the display.

Utilize this drive recorder to carry out the method for spatial analysis, comprise the steps:

(1) utilizes image information in the image sensor collection driving process; Utilize latitude and longitude coordinates and speed in the gps data receiver collection driving process; Utilize the acceleration of gravity of X, Y, Z axis in the gravity sensor collection driving process;

(2) the various information that gather in the step (1) are stored in the SD card;

(3) the CPU processor is transferred image information and latitude and longitude coordinates information from the SD card, and converts latitude and longitude coordinates to track display on image, shows at display by the internal memory output module;

(4) the CPU processor is transferred velocity information from the SD card, as the foundation of arrow mark acceleration and deceleration, at track place of arrival mark.

(5) the CPU processor is transferred the gravity acceleration value of X, Y, Z axis from the SD card, shows the acceleration of gravity situation of X, Y direction on display with the form of both sides' block diagram, shows the acceleration of gravity situation of Z-direction with color.

Image sensor stores in the SD memory card by the CPU processor after the video recording of the driving in the driving process is filmed, the gps data receiver is passed back along road latitude and longitude coordinates and speed simultaneously, and relevant information stored in the SD memory card by the CPU processor, when playing the video recording picture of image sensor collection by display, utilize the CPU processor automatically to transfer video recording picture and latitude and longitude coordinates in the SD memory card, the relevant informations such as speed, when display is play video recording, latitude and longitude coordinates converts trajectory diagram to and is presented on the video recording picture, and show track the road information of process, speed is marked at the track place of arrival as the foundation of arrow mark acceleration and deceleration, allows the user know that clearly automobile proceeds to the relevant position of terrestrial coordinates.

Receive the acceleration of gravity of X, Y, Z axis in the driving process by gravity sensor, and relevant information stored in the SD memory card by the CPU processor, when display is play video recording picture and trajectory diagram, by the CPU processor multidimensional acceleration of gravity figure is shown on the video recording picture simultaneously, allow the user open-and-shut know produce wherein unusual change in gravitational acceleration situation.Multidimensional acceleration of gravity figure as shown in Figure 2, the gravity acceleration value of X, Y-axis is larger, then gravity identifier 1 can drop on the more peripheral of both sides' frame, Z axis acceleration of gravity represents its size by the different colours of gravity identifier 1.
