[0053] More specifically, when this embodiment is used, under the action of the correction module 31, the front view camera 2 can be automatically corrected, and the precise geometric mapping relationship can be obtained to obtain the best image quality. The automatic correction method includes:

[0054] Collect multiple sets of images through the built-in image acquisition module;

[0055] The key points of two samples in each group of sample images are extracted by using the key point extraction algorithm through the extraction module;

[0056] According to the key point matching pair and the camera internal parameters, the recoverPose algorithm is used to determine the rotation matrix corresponding to the camera posture and the unit direction vector of the corresponding translation vector;

[0057] The filtering error is fitted through Gaussian distribution;

[0058] Perform optimization calculation based on the initial value, the filtered rotation matrix and the filtered unit direction vector to determine the correction rotation matrix and the correction translation vector;

[0059] The matrix calculation formula is as follows:

[0061] in, Represents a real number set of filter rotation matrices, r represents the relative value of the rotation matrix, i represents image sample information, the unit is frame, and the i-th frame and the i+1-th frame are an image pair: Represents: the rotation matrix corresponding to the i-th frame left camera sample image and the i-th frame right camera sample image; Represents the rotation matrix corresponding to the i+1th frame left camera sample image and the i+1th frame right camera sample image; Represents the rotation matrix corresponding to the left camera sample image of the i-th frame and the left camera sample image of the i+1-th frame;

The rotation matrix can be calculated by the Rodriguez formula, which is as follows:

[0066]

[0067] In the above formula, Represents the unit direction vector of the translation vector of the i-th frame, The unit direction vector representing the translation vector of the i+1th frame;

[0068] For example, assuming that the i-th frame and the i+1-th frame are the first frame and the second frame of the image respectively, the translation error between the two is:

[0073] An electric telescopic rod 13 is fixedly mounted on the inner wall of the inner cavity 11 , and a telescopic end of the electric telescopic rod 13 is fixedly connected to the moving frame 14 .

[0074] The shielding component also includes a telescopic rod 33 fixedly mounted on the surface of the buffer plate 9, the end of the telescopic rod 33 is fixedly connected to a connecting block 34, and the end of the connecting block 34 is fixedly connected to a semicircular cleaning ring 19.

[0075] The cleaning component includes a micro motor 21 disposed in the buffer plate 9, the output shaft of the micro motor 21 is fixedly connected to a rotating shaft, and the surface of the rotating shaft is fixedly connected to a gear 1 20;

[0076] It also includes a rack row 32 meshing with the gear 20, the upper surface of the rack row 32 is fixedly connected with a slider 22, the inner wall of the buffer plate 9 is provided with a slide groove 42 through which the slider 22 extends and slides, the end of the rack row 32 is fixedly connected with a limit rod 38, the surface of the limit rod 38 is slidably connected with a moving block 40, the lower surface of the moving block 40 is fixedly connected with teeth 43 meshing with the gear 20, a spring 39 is commonly provided between the moving block 40 and the rack row 32, a hinge block 41 is hinged on the side of the moving block 40, and a hinge plate 37 is commonly provided between the hinge block 41 and the connecting block 34.

[0077] A disc 1 36 is arranged on the surface of the buffer plate 9, a telescopic rod 2 is arranged on the surface of the disc 1 36, the end of the telescopic rod 2 is fixedly connected with a disc 2, and a buffer spring 35 is arranged between the disc 1 36 and the disc 2.

[0078] A rectangular notch 28 is provided on the inner wall of the inner cavity 11, and a moving block 2 30 is slidably connected to the inner wall of the rectangular notch 28, and a spring 3 29 is provided between the moving block 2 30 and the inner wall of the rectangular notch 28, and the end of the moving block 2 30 extending out of the rectangular notch 28 is fixedly connected to the connecting block 2 16, and the surface of the connecting block 2 16 is hinged with a hinge plate 2 15, and the end of the hinge plate 2 15 is hinged with a connecting block 3 24, and the lower surface of the connecting block 3 24 is fixedly connected with a slider 25, and a sliding groove 26 is provided on the inner wall of the inner cavity 11 for the slider 2 25 to extend and slide;

[0079] A rack row 27 is fixedly connected to the surface of the connecting block 3 24 , a rotating rod 17 is fixedly connected to the upper surface of the side view camera 18 , and a gear 2 23 meshing with the rack row 27 is fixedly connected to the surface of the rotating rod 17 .

[0080] like Figure 1 As shown, the driving recorder body 1 is connected to an appropriate position in the vehicle through the connecting piece 4. In this state, the buffer plate 9 is located below the driving recorder body 1. At this time, the upper surface of the disk 2 is in contact with the lower surface of the driving recorder body 1, and the buffer spring 35 is in a compressed state and has a certain elastic potential energy. When the vehicle is driving on a bumpy road and accidentally shakes the driving recorder body 1 off, the driving recorder body 1 can be protected under the action of the elastic potential energy of multiple buffer springs 35, so as to avoid damage to the precision components in the driving recorder body 1 and cause unnecessary economic losses.

[0081] like Figure 2 , Figure 3 and Figure 5 As shown, when the vehicle stops, the electric telescopic rod 13 is controlled to extend, driving the moving frame 14 to move downward, and the downward movement of the moving frame 14 will cause the moving rod 6 to move in the slide rail 7. During this process, the moving rod 6 will first pass through the rectangular slide rail in the slide rail 7, and drive the connecting plate 8 and the buffer plate 9 to move vertically downward for a distance. At this time, as the buffer plate 9 moves vertically downward, the disc 2 will be separated from the driving recorder body 1, so that the buffer spring 35 can be restored to a non-compressed state. Since the vehicle is in a stopped state at this time, the driving recorder body 1 in the vehicle will not be affected by a large external force and fall. Therefore, when the vehicle stops, it does not need to be protected by the buffer plate 9 and the buffer spring 35.

[0082] As the moving rod 6 continues to move in the arc-shaped slide rail, the connecting plate 8 and the buffer plate 9 will be deflected. When the moving rod 6 moves to the end of the arc-shaped slide rail, the buffer plate 9 will move to the end of the arc-shaped slide rail. Figure 7 As shown, at a position parallel to the horizontal direction of the driving recorder body 1, the buffer plate 9 is located on the side of the front-view camera 2. At this time, under the action of the buffer plate 9, the front-view camera 2 can be protected when the vehicle stops, so as to avoid the problem that the strong sunlight will cause permanent and irreversible damage to the front-view camera 2 when the vehicle is parked in an open-air parking lot with strong light, thereby extending the service life of the front-view camera 2.

[0083] It is worth noting that Figure 7~Figure 10 As shown, when the buffer plate 9 moves to Figure 7 After the state shown, the micro motor 21 is turned on to drive the rotating shaft to start rotating, so that the gear 20 rotates. As the gear 20 rotates, the rack row 32 moves. As the rack row 32 moves, under the hinged action of the hinge plate 37, the connecting block 34 and the semicircular cleaning ring 19 move toward the direction close to the front-view camera 2.

[0084] like Figure 7 As shown, when the rack row 1 32 and the gear 1 20 are meshed, the semicircular cleaning ring 19 will also move to the position on the right side of the front-view camera 2. At this time, as the gear 1 20 continues to rotate, as shown in FIG. Fig.10 As shown, the gear 20 will mesh with the tooth 43 on the moving block 40, and the tooth 43 will be driven to move to the left. During this process, the spring 39 will be compressed. As the gear 20 continues to rotate, when the gear 20 is disengaged from the tooth 43, the elastic potential energy of the spring 39 will drive the tooth 43 and the moving block 40 to move in the opposite direction and reset, and the tooth 43 will mesh with the gear 20 again. That is, when the gear 20 is meshed with the rack row 1 32, as the gear 20 is moved, the gear 20 will be moved back to the rack row 32. Rotation will cause the moving block 40 to reciprocate, and under the hinged action of the hinged plate 37, the reciprocating movement of the moving block 40 will cause the connecting block 34 and the semicircular cleaning ring 19 to reciprocate in the horizontal direction. As the semicircular cleaning ring 19 reciprocates, it can reciprocate in contact with the front-view camera 2, thereby cleaning the dust on the surface of the front-view camera 2, so as to ensure the long-term use of the front-view camera 2 and improve the recording effect of the front-view camera 2, thereby extending the service life of the driving recorder body 1.

[0085] like Figure 4~Figure 6As shown, as the moving frame 14 moves downward, when the moving frame 14 moves to a position in contact with the connecting block 2 16, as the moving frame 14 continues to move downward, the connecting block 2 16 will move downward synchronously. At this time, under the hinged action of the hinged plate 2 15, the rack row 27 will move, so that the gear 2 23 can start to rotate. As the gear 23 rotates, the rotating rod 17 can drive the side-view camera 18 below to rotate 120 degrees, so that the two side-view cameras 18 can rotate to the direction facing the inside of the vehicle and monitor the situation inside the vehicle in real time. That is, after the vehicle stops, when the buffer plate 9 switches its position to protect the front-view camera 2, the two side-view cameras 18 will also switch to a position where the situation inside the vehicle can be monitored, and an alarm can be sounded when criminals are found in the vehicle, thereby improving the safety performance of the driving recorder body 1 and making it more practical.

[0086] Based on the above-mentioned driving recorder with self-correction angle, an embodiment of the present invention further proposes a method for using the driving recorder with self-correction angle. Exemplarily, the method includes:

[0087] During the driving process of the vehicle, the front view camera and the side view camera are automatically calibrated through the calibration module, with precise geometric mapping relationship to obtain the best image quality;

[0088] When the vehicle is parked, the shielding component drives the buffer plate to rotate to the side of the front-view camera and shields the front-view camera for light protection;

[0089] Use the cleaning components in the buffer plate to clean the dust on the surface of the front view camera.

[0090] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
