Around View Monitor


The Ourvisual 360º 3D Surround View Monitoring Technology synthesizes images from four cameras to create a true 3D sophisticated view of a vehicle's surroundings. The technology enables flexible omni-directional monitoring around a vehicle from a dynamically definable perspective or "free eye point." The Ourvisual SVM Technology can display the complete vision of the positioning and moving path of the car, it eliminates blind spot and thus works perfectly as a safe parking and driving guide even when restricted by adjacent vehicles and objects, parking line, etc. Ourvisual offers various SVM system configurations like -HDMI/VGA/AV with alternative version of 2D or 3D。

 Product principles：


360 degree surround view monitoring system(SVM), the four ultra wide angle camera mounted on the vehicle the front,rear,left and right mirror, the vehicle can perceive the surrounding environment, through the virtual scene reconstruction technology, can be achieved including top, front and back angle of view, view forward / reverse, left and right side view, any virtual view image view a variety of virtual view, provide a full range of image information around the vehicle for the driver, the driver to eliminate traditional visual dead, make driving more safe and free.

 Product Features：


360 degree surround view monitoring system(SVM) for the driver to provide low-speed, vertical parking, side parking, reversing, narrow access, the surrounding environment, such as observation of several typical scenes of the auxiliary driving angle image. Through the interconnection with the vehicle bus, the system can be through the speed, stalls, left and right turn signal, far light and other signals, to achieve rapid switching of view / image to avoid the driver "rush" situation.

 Technical advantages：


In the application of panoramic parking, relative to the lens distortion correction, image fusion and splicing and other basic technologies, Zhiyuan in the best use of hardware, software, the principle of excellence, the bottom of the panoramic parking technology in-depth study.

 Camera position:


  1. The choice of car front grille grid plate position, the camera embedded.

  2. Connect the camera cable with the extension line, waiting for the next test and debugging.

  3. The location of the installation needs to ensure that the camera line of sight and the ground can not be too much occlusion, otherwise it will cause difficulty stitching panorama.

  4. The camera through the gap with the screw column logo and nut fixed plate.

Wide range view with 180 degrees wide angle by wide-angle camera. When reversing, wide angle mode can be confirmed to the front and rear directions close to the vehicle and pedestrians. Sign line auxiliary backing storage. 


Value


Reversing, through the wide-angle camera image to confirm the rear view, improve sense of peace.

 The Installation method of front camera:


  1. Insert the front camera to the center of the front vehicle logo.

  2. Connect the front camera with the extending cable.

  3. Please double check the field of the view is wide enough or not from the system preview menu window, and the camera should not be covered by front bumper.

  4. Fix the front camera with screw and the metal pad accessories.  

 Rear Camera Installation Steps：


  1. Unpack the inner panel of the trunk and take out the left license plate LED.

  2. Stick locating plate of the rear camera in the right place for drilling a hole, and then drill a hole to install the camera on the position of the left side of license plate lamp.

  3. Distribute the extending cable of the rear camera from the license plate lamp and go along the original wire distribution tube to the tool cabinet position.

  4. To connect reversing signal of the rear camera extending cable to the 12V anode of the reversing lamp.

  5. When video in DVD monitor works well after camera connected, you can recover the trunk panel.

 Right and Left Camera Installation：


  1. As showing in the left picture, stickthe locating plate of the rear camera tothe bottom of the wing mirrors.

  2. Using the corresponding drilling bit to drill holes at the bottom of plastic shell, and then tear off the positioning stickers.

  3. Select the embedded mounting or external outboard mounting for side cameras according to the spare space of the plastic shell.

  4. If the drilling location available in the bottom of the plastic shell is not flat,please use a rubber pad provided along with the product packing list.

  5. Install the internal spherical camera core, and connect the cables, then lock screw of side cameras tightly but keep the spherical camera core of side cameras can still be rotated.

  6. Connect the extending cables which are waiting for the coming testing and debugging procedure.

  7. Open the center screen to see the preview image of the side cameras,keep in mind that keep the left calibration tap visible while get as many pixel as possible, and a another important comments is that keep all the calibration point distributed properly on the center screen. Recommended distribution is list blow.

Common left and right side view camera installation method

TIP：

  1. Drilling hole diameter of outboard mounting is "6mm", Drilling hole diameter of embedded mounting is;18 ~ 26mm", Please select the appropriate location to drill the hole for universal cameral models. And keep in mind that the glass face of the side mirror should be free adjusted, so that the embedded camera should not block the movement of the glass face.

  2. Choose a proper drill bit according to the camera size Find a flat area near to the edge of the wing mirror bottom plastic shell as much as possible for getting enough pixel content. You should leave enough spare space for the glass face of wing mirrors so that the glass face can be adjusted freely. What’s more, keep in mind that camera field of view (FOV) should be prevent from covering by the plastic shells. 

Cameras Angle Adjusting

For adapting to different shape of wing mirror plastic shell, the angle and direction of side cameras are always designed to be free adjusted. Rotate the side cameras according to the image to keep vehicle body in image closely to the side calibration line and meanwhile keep the pixel in wider angles and farther places can be captured as many as possible. Keep the left and right calibration point distributed in symmetrical position in the screen.  

Next step, the mirroring setting of the camera sensor need to be set according to camera installation direction. The guideline for this setting is to make the pixel content of the image as same as the instruction show in the system calibration preview menu. Generally speaking, except for the rear camera, all other cameras must be original image.

Trouble 1 

Some part of the image is blank after execution of Fast Merging mode

If you are indeed confirmed that all these above-mentioned steps are correct, please use your smart phone to take a photo after you finish each step when move done all cross cursor to these corresponding calibration points to us, our system can dump all these calibration data to TF card and our technical team will help you to find the root cause of the problem once we get your calibration data. Please contact our sales if you need more instructions on how to dump the calibration data. 

Trouble 2 

Picture after merging is not accurate or seamless

This problem is mainly caused by the installation position, and it usually occurs  with the lower chassis vehicles .The picture quality captured by the camera will be poor and so that the calibration error will be magnified. This issue could be result of lack of enough care taken while moving the cursor between the calibration points . 

Trouble 3

Some part of the picture after merging is mirrored

If you have selected some OEM camera from your own supplier chain, please confirm whether the image from the sensor is mirrored or not, and if mirrored, please choose the mirror function in the menu. 

Trouble 4

The corner part of the picture is blank

These problem may be caused by the camera itself, please make sure if the camera get sufficient pixel content after camera installation(whether the installation position is too close to the ground)

Trouble 5

The merging result is completely fail

  1. Be careful to choose a proper vehicle size when starting the camera calibration. The vehicle type parameter must be set according to the size of the vehicle. Mismatch could result to such issues.

  2. Make sure there should be no obtuse mistakes e.g., while calibrating the rear camera you are mistakenly choosing the front camera or  making a mistake for the left/right direction.

  3. Please use your smart phone to take a photo after you finish each step when move done all cross cursor to these corresponding calibration points to us, our system can dump all these calibration data to TF card and our technical team will help you to find the root of the problem once we get your calibration data. Please contact us if you need more instructions on how to dump the calibration data.
