In some embodiments of the present invention, the driving assembly further includes a position detecting device (not shown) connected to the ring mount 20 to detect the current position of the ring mount 20, so that the current position of the ring mount 20 can be transmitted to the signal processing unit, thereby improving the accuracy of switching the night vision camera and the image camera by a user.
As shown in fig. 1 and 2, in some embodiments of the present invention, the vehicle-mounted imaging device 100 is further provided with a signal processing unit (not shown) disposed on the base 10 and respectively connected to the driving assembly (driving unit 31) and the night vision imaging device and the image imaging device, and the signal processing unit may receive imaging signals of the night vision imaging device and the image imaging device, process the received images, and further control the driving unit 31 to rotate according to the processing result, thereby controlling the ring-shaped mounting 20 to rotate to switch between the night vision mode and the image mode.
In a further example of the present invention, in a situation where the visual environment is good, the image capturing device is usually in a horizontal position (a preset position), and at this time, the image capturing signal detected by the image capturing device may be transmitted to the signal processing unit, and the signal processing unit has preset signals, such as parameters such as preset image characteristics and pixel entropy integration, and when the image capturing signal detected by the image capturing device is a severe environment with poor light, such as night, fog, heavy rain, sand storm, and the like, the signal processing unit matches the received image capturing signal with the preset signals, such as matching the parameters such as the image characteristics and the pixel entropy integration of the image capturing signal with the preset signals, and when the image characteristics and the pixel entropy integration of the image capturing signal are consistent with the preset signals, the signal processing unit may determine that the current environment is a poor visual environment according to the matching result, and control the driving unit 31 to rotate, thereby driving the annular mounting base 20 to rotate to switch the night vision capturing device, thereby switch to night vision mode, improve the environment recognition effect effectively.
For example, in some examples, the preset angle α between the line connecting the night vision camera and the center of the ring mount 20 and the line connecting the image camera and the center of the ring mount 20 is 90 °, and then rotating the ring mount 20 clockwise by 90 ° at this time switches the night vision camera to the horizontal position (preset position).
As shown in fig. 5, further, in order to improve the control accuracy of the driving unit 31 and ensure the reliability of the adjustment, the signal processing unit detects the position of the rotor rotating shaft of the driving unit 31 according to the position detecting device, and further obtains the rotating shaft position of the rotor rotating shaft of the driving unit 31 in the reference coordinate system of the signal processing unit through processing, and uses the error between the actual rotating speed and the reference rotating speed, the speed controller outputs iq to realize the control of the torque of the driving unit 31, the given value of id is usually 0, and the torque is determined by the rotor magnetic field and the current id.
The signal processing unit is internally integrated with a three-phase six-pulse wave controllable rectifier, and a semi-controlled thyristor is adopted to replace a diode. The thyristor has the function of delaying the switch conduction, the delay angle being indicated by the firing angle. The thyristor is turned on after delaying the angle based on the forward bias point. By changing the firing angle, the anode voltage and the cathode voltage can be changed, so that the output voltage of the rectifier is changed, and the purpose of controlling the driving unit 31 to move is achieved.
In some embodiments, the position detection device may detect the current position of the night vision camera and the current position of the image camera, when a user needs to switch the night vision camera or the image camera to a preset position, the signal processing unit may control the rotation speed of the driving unit 31 at variable speeds to ensure the rotation accuracy of the ring mount 20, for example, the required rotation angle for switching the night vision camera or the image camera from the current position to the horizontal position is a stroke angle, the driving unit 31 may control the night vision camera or the image camera to rotate 20% of the stroke angle at a rated speed, then gradually decelerates, and rotates to the horizontal position at a lower speed in the last 20% of the stroke angle range, thus, the rotation of the annular mounting seat 20 is controlled in a stepwise variable speed manner, excessive rotation is avoided, and control accuracy is improved.
In some embodiments of the present invention, in order to ensure dynamic balance of the ring-shaped mount 20 after the night vision camera and the image camera are mounted, the center of mass of the ring-shaped mount 20 after the night vision camera and the image camera are mounted substantially coincides with the center of the ring-shaped mount 20, for example, by providing a symmetrically arranged night vision camera, a symmetrically arranged image camera, a first counterweight substantially equal to the weight of the night vision camera, a second counterweight substantially equal to the weight of the image camera, and the like, dynamic unbalance caused by the weight unbalance during rotation of the ring-shaped mount 20 and further influence the reliability of adjustment can be avoided.
As shown in fig. 1, in some embodiments of the present invention, the outer peripheral wall of the annular mounting seat 20 may be provided with two mounting grooves 21, the two mounting grooves 21 are recessed toward the center of the annular mounting seat 20 along one radial direction (e.g., a left-right direction in fig. 1) of the annular mounting seat 20, and the two image photographing devices are mounted in the two mounting grooves 21 in a one-to-one correspondence, so that the centroid of the two image photographing devices can be located at the center of the annular mounting seat 20 as soon as possible according to the mounting of the image photographing devices, and the reference base point of the image photographing devices can be located at substantially the same point as the reference base point of the radar provided on the base 10.
In this way, in the vehicle cruising mode, the signal processing unit establishes a world coordinate system according to the radar, establishes an image coordinate system after receiving the camera shooting signal of the image camera shooting device, and can simplify the algorithm of the mapping relation between the image coordinate system and the world coordinate system and facilitate the completion of road surface detection because the reference base points of the two are approximately at the same point.
Further, the number of the night vision cameras may be two, the two night vision cameras are symmetrically arranged along the other radial direction of the annular mount 20 and are located on the front end surface of the annular mount 20, and the connecting line between the two image cameras and the connecting line between the two night vision cameras are orthogonal to each other, so that the center of mass of the two night vision cameras is also approximately located at the center of the annular mount 20, and by arranging the night vision cameras orthogonal to each other, the annular mount 20 can be further kept in dynamic balance, and the rotational stability is improved.
