Description

Technical Field

[0001] This invention relates to the field of intelligent vehicle air conditioning and human-computer interaction technology, and in particular to a dynamic avoidance air supply method for vehicle air conditioning based on human posture recognition. Background Technology

[0002] In recent years, with the rapid development of intelligent connected and artificial intelligence technologies, in-vehicle air conditioning systems are gradually evolving from traditional directional airflow and constant air volume control towards personalization and intelligence. Sensor fusion-based air conditioning comfort adjustment solutions are emerging in large numbers, using technologies such as temperature and humidity sensing, CO2 concentration monitoring, and facial recognition to perceive and actively adjust in-vehicle environmental parameters in real time. Furthermore, human posture recognition technology has achieved significant breakthroughs in the field of computer vision; depth cameras, TOF sensors, and multimodal fusion algorithms have made high-precision 3D posture modeling possible. By extracting the coordinates of key points such as the head, hands, and torso, researchers can track human movements within a millimeter-level range, which can then be applied to various scenarios such as assisted driving, fatigue detection, and in-vehicle human-machine interaction. However, deeply coupling human posture recognition with in-vehicle air conditioning systems to achieve dynamic obstacle avoidance and precise air delivery is still in the theoretical exploration and engineering testing stage.

[0003] Most existing in-vehicle air conditioning adjustment methods are based on preset airflow direction or manual adjustment, failing to dynamically avoid changes in occupant posture in real time. This often results in discomfort caused by airflow directly hitting the head or hands. While some smart air conditioners can achieve face-tracking airflow, they are limited to two-dimensional planar adjustments, ignoring the constraints of the occupant's three-dimensional posture and surrounding interaction area. Furthermore, current louvered airflow direction indicators or airflow control units often use mechanical stepper motors, which have limited adjustment accuracy and response speed, insufficient to meet the needs of frequently iterated path planning and boundary avoidance. On the other hand, solutions based on large-area airflow struggle to balance energy saving and localized comfort. The lack of effective protection and avoidance mechanisms for critical body parts (such as the head and hands) presents a significant bottleneck in achieving a balance between safety and comfort with current technologies.

The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0050] Reference Figure 1 This is the first embodiment of the present invention, which provides a method for dynamic obstacle avoidance air supply in vehicle air conditioning based on human posture recognition, including:

[0051] S1: Acquire and fuse the occupant's human posture data to construct a 3D posture model containing key point coordinates;

[0052] Specifically, a TOF (Time-of-Flight) camera is used to acquire occupant depth images, with each pixel recording its depth (z-axis distance) information. A 3D coordinate point cloud is constructed from the depth map, and human pose estimation algorithms (such as OpenPose3D or MediaPipe) are used to extract the coordinates of skeletal key points.

[0053] The thermal imager acquires corresponding infrared thermal images, with each pixel representing the temperature value (unit: °C) at the corresponding location. After emissivity correction and ambient temperature compensation, a temperature distribution matrix is ​​obtained.

[0054] Camera calibration and coordinate mapping are performed. External parameter calibration is conducted on the TOF camera and thermal imager to obtain rotation and translation matrices, which are used to map the thermal imaging coordinates to the corresponding 3D space of the depth map, represented as:

[0055] ;

[0056] in: The coordinates of a pixel in an infrared thermal imaging image in three-dimensional space; These are the 3D coordinate points corresponding to the TOF point cloud; and These are the rotation and translation matrices of the thermal imager relative to the TOF camera, obtained through calibration.

[0057] Construct fusion data voxels and map temperature values ​​to each three-dimensional point, that is, attach temperature attributes to each three-dimensional coordinate point to form four-dimensional voxel data.

[0058] A 3D pose model is constructed, using human pose estimation keypoints to build the skeletal structure. Local temperature anomaly detection is performed, and a local region is constructed around each skeletal segment (e.g., a sphere for the head, a cylinder for the arms). Gradient analysis of the temperature distribution within this region is conducted. If a region exhibits a significant temperature gradient (e.g., a gradient ≤ 0.3℃ / cm at the shoulder), it is identified as a region with thick clothing, which can be used to adaptively adjust the size of the protected area. The final output model is as follows:

[0059] ;

[0060] in: It is a three-dimensional pose model. The three-dimensional coordinates of the key points of the skeleton; For skeleton connection pairs; For key local temperatures; This represents the temperature gradient of the bone segment.

[0061] S2: Based on the 3D posture model, identify the key points of the head and hands, construct a head protection sphere with the key points of the head as the center, and construct a no-go zone for hand operation with the geometric center of the steering wheel;

[0062] Specifically, input the set of key points of the 3D posture model, preset parameters, default head protection sphere radius, temperature difference compensation radius increment, steering wheel geometric center coordinates, and hand operation restricted area radius; read the coordinates of the head and hand key points from the 3D posture model.

[0063] Construct a protective sphere for the head, determine the key point of the head as the center of the sphere, and calculate the radius increment based on the local temperature gradient, as follows:

[0064] ;

[0065] ;

[0066] in: This refers to the radius of the head protection sphere after the increment. The default head protector sphere radius, It is an increment function. This represents the maximum temperature difference in the head region. The lower limit threshold of temperature difference. The upper limit threshold for temperature difference. This is the lower limit of the radius increment. This represents the upper limit of the radius increment.

[0067] Construct a no-go zone for hand operations, obtain the known geometric center of the steering wheel in the vehicle coordinate system, and create a small sphere for each hand, with the center being the key point of the hand and the radius being the default hand operation radius.

[0068] When the airflow path or movable parts enter the protected sphere or the hand restricted area, it triggers avoidance or wind direction adjustment.

[0069] S3: The flow path is planned using cubic Bézier curves, and the angle combination of piezoelectric ceramic units in the louver matrix is ​​calculated to achieve dynamic avoidance air supply control of the vehicle air conditioner.

[0070] Specifically, a cubic Bézier curve is used to plan the airflow path. Using the tangent plane of the head protection sphere as a constraint, the angle combination of the 128 piezoelectric ceramic units in the louver matrix is ​​calculated to ensure a minimum safe distance of 3cm between the airflow trajectory and the boundary of the avoidance space. When the infant is detected to be asleep (body surface temperature fluctuation <0.1℃ / min), a gentle breeze surround mode is activated, locking the wind speed limit to 1.8m / s.

[0071] Based on the determined head protection sphere, a safety gap (e.g., 3cm) is added as a clearance boundary. A cubic Bézier curve is used to describe the airflow path from the air outlet to the target point. This curve is determined by four control points: the start point, the end point, and two intermediate control points, expressed as:

[0072] ;

[0073] ;

[0074] in: for The path of airflow from the air outlet to the target point at any given time. For the location of the air supply vent, The target point location, and For Bessel control points, The head protects the center of the sphere. For safety clearance;

[0075] Through numerical optimization algorithms, under the condition that the distance between the point on the curve and the center of the protective sphere is not less than a certain value when any curve parameter is taken, a set of intermediate control points is found so that the Bezier curve is both smooth and as close as possible to a straight path, so as to ensure that the airflow is as straight as possible and does not violate the limited area.

[0076] After optimization, the curve is divided into several small segments, each corresponding to a small segment of airflow direction. For each segment, the direction of the line connecting the start and end points of the segment is calculated as a local wind direction unit vector, and the wind speed is assigned according to a predetermined local wind speed scale to obtain the target local wind vector, expressed as:

[0077] ;

[0078] ;

[0079] in: For local wind direction, for The path of airflow from the air outlet to the target point at any given time. for The path of airflow from the air outlet to the target point at any given time. For the target local wind vector, This refers to local wind speeds;

[0080] These segmented target wind vectors are mapped onto the piezoelectric ceramic elements of the louver matrix. Based on the calibration coefficients and rotatable angle range of each element, it is assumed that each element can contribute a local wind direction at a given deflection angle. The wind directions of all elements are then approximated by linear superposition to see if the required target local wind vector can be reconstructed, expressed as:

[0081] ;

[0082] ;

[0083] in: For a given driving angle in Local wind vector of the piezoelectric ceramic unit This is the calibration factor for the maximum width of the piezoelectric ceramic unit. Let be the rotation matrix about the hinge normal of the piezoelectric ceramic unit. The initial orientation unit vector of the piezoelectric ceramic unit. For the airflow path number The given driving angle of the time-limited piezoelectric ceramic unit;

[0084] Therefore, a least-squares optimization problem is established for each segment: within the movable range of each piezoelectric ceramic unit, a set of deflection angles is found, and the solution is quickly obtained by gradient descent so that the sum of the wind direction vectors of all units is closest to the target vector.

[0085] Within each cycle, the system acquires the latest headline key points, replans the Bezier path, recalculates the target wind vector in segments, and resolves the piezoelectric ceramic unit angles. If the curve planning fails or avoidance constraints cannot be met due to sturdy occupant movement, the system immediately reverts to the default direct wind mode and initiates a new path planning.

[0086] This embodiment also provides a computer device applicable to the dynamic obstacle avoidance air supply method for vehicle air conditioning based on human posture recognition, including: a memory and a processor; the memory is used to store computer-executable instructions, and the processor is used to execute the computer-executable instructions to implement all or part of the steps of the method described in the above embodiments of the present invention.

Furthermore, by combining curve planning and multi-unit airflow inverse kinematics, it brings real-time, high-precision dynamic avoidance airflow capability to the vehicle's air conditioning system.
