AI Function Overview
<p>[TOC]</p>
<h3>I. Summary Description</h3>
<p><strong>The device can support a variety of AI function combinations, including: DMS, ADAS, DMSX, BSD, 360, driver identification, headcount statistics, etc. For details, please refer to the [AI function specification combination list.xlsx](<a href="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&sign=557ce042713eafd6d9cc9e64fae78631">http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&sign=557ce042713eafd6d9cc9e64fae78631</a> "[AI function specification combination list.xlsx")</strong></p>
<p><strong>DMS: Driving State Monitoring System:</strong> Using the images acquired by the DMS camera, the driver's driving behavior and physiological state are detected through visual tracking, target detection, action recognition and other technologies to alert and warn the driver.</p>
<p><strong>ADAS:Advanced Driver Assistant System :</strong> Real-time monitoring of the vehicle ahead of the driving environment, when the vehicle detects potential danger, will issue an alert to alert the driver to abnormal vehicle or road conditions</p>
<p><strong>DMSX: Driver seat belt monitoring: </strong>Using the image acquired by the top view camera, the image area of the driver's torso is extracted, and the driver's driving behavior is detected through visual tracking, target detection, action recognition and other technologies to alert and warn the driver.</p>
<p><strong>BSD: Blind Spot Detection: </strong> Installed in the vehicle front, rear, left and right around the camera probe, uninterrupted detection in the vehicle on the left and right sides of the blind spot range of objects (such as pedestrians), to remove the car's visual blind spot, such as into the blind spot range, will issue an alarm to remind motorists to pay attention to the blind spot range of pedestrians.</p>

<h3>II. Conditions of use</h3>
<p>1, <strong>Prepare the corresponding camera, in order to guarantee the accuracy of AI algorithm, you need to use the corresponding camera, fisheye BSD is applicable to 360 panorama, please refer to the following </strong></p>
<p>1.1 DMS camera: DMS alarm requires the use of DMS camera, can refer to the following chart.</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=2ea4cf7ec6ea74a3fd9da74e19662b48" alt="" /></p>
<p>1.2、BSD camera: Left and right BSD cameras can be selected as normal/fisheye, if both BSDs are open, the camera type needs to be the same.</p>

<p>1.3、Fisheye BSD: Fisheye cameras are required for front and rear BSD, three-way and above BSD.</p>

<h3>III. Cautions</h3>
<ol>
<li>Such as open the left and right blind channel, the camera must be consistent (fisheye / ordinary).</li>
<li>Before and after the blind channel open, the camera must be fisheye.</li>
<li>Before / after and left / right mixed double blind area, the camera must be both fisheye.</li>
<li>Three blind channels and above all open, the camera must be fisheye.</li>
<li>AI algorithm channel can not be the same channel, otherwise prompt: channel settings are illegal and can not be saved.</li>
<li>The total number of AI algorithm channels and passenger flow statistics channels cannot exceed 4.</li>
<li>AI algorithm and passenger flow channel can not be the same.</li>
<li>ADAS alarm: pedestrian collision alarm will be triggered only if the current speed is between speed value and classification value.</li>
<li>BSD alarm: the current speed needs to be lower than the speed value before the alarm is triggered, no classification setting item.</li>
<li>DMS: the sensitivity value can be set at will, in seconds, for how long before the alarm is triggered, effectively preventing false alarms and false alarms.</li>
<li>ADAS\BSD: sensitivity level of 10 (drop-down option); the smaller the number, the more sensitive the detection.</li>
</ol>
<h3>IV. Process guidelines</h3>
<p><strong>Prerequisites:</strong></p>
<h4>1、 According to the demand, install the suitable camera</h4>
<ul>
<li>
<p><strong>DMS:</strong> DSM camera needs to be installed on the dashboard in front of the steering wheel, the preferred installation location should be in a straight line with the steering wheel centerline. If you encounter the installation center point is not convenient or affect the driver's driving vision, you can move to the left and right sides of the steering wheel, the maximum moving range can not exceed the steering wheel's outer diameter edge line(Camera can refer to DMS picture above).</p>
</li>
<li>
<p><strong>ADAS:</strong> The camera is fixed in the central position of the front windshield, centered on the central axis of the vehicle, and the intersection of the horizontal line above the wiper and the central axis is the best installation position of the device (note that it should not be blocked by the wiper).</p>
</li>
<li>
<p><strong>DMSX:</strong> installed on the left side of the front of the car for the top view installation, may be due to different models and lenses related to the field of view to fit the driver and the steering wheel can be.</p>
</li>
<li><strong>BSD:</strong> The camera should be installed at the most backward edge of the blind spot (lateral BSD is recommended to be installed at the right rear), in order to better detect the pedestrians in the blind spot, the installation position should be about 1.8 meters above the ground, and the camera angle should be adjusted to face slightly outward and downward, so that the picture can cover most of the blind spot and the car body in the picture does not account for more than 25%.</li>
</ul>
<h4>2、Upgrade to use software with AI function</h4>
<ol>
<li>Upgrade the AI program (ext file) with the main program, which can be provided with our technology.</li>
<li>Some equipment hardware has AI certification, upgrade the corresponding main program can.</li>
<li>Specific upgrade process can be referred to.</li>
</ol>

<h4>3、Frame description</h4>
<ol>
<li>The colors of DMS frame, white and red, indicate no alarm and alarm respectively.</li>
<li>The colors of the ADAS frame, white, yellow and red, indicate the detection of no alarm, too close, and collision alarm, respectively.</li>
<li>The color of the BSD frame is divided into green, blue, yellow and red, which indicate that no alarm, level 3, level 2 and level 1 alarm are detected respectively.
The accuracy of the test needs to be well calibrated to be accurate.</li>
