Vehicle Projection Field Control for Camera Residual View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for projecting objects onto a vehicle's surroundings, such as road surfaces, can cause confusion between projected and real objects, leading to malfunctions in vehicle control and potentially life-threatening situations due to the driver assistance system's inability to distinguish between them.
Innovation Solution
A method and device that project objects using a vehicle's projection device with an adjustable projection field, controlled by a control device, to ensure the field of view unobstructed by projections meets a sufficiency criterion for reliable environmental perception by the vehicle camera, adjusting the projection field based on current vehicle operating parameters and maintaining a clear residual field of view for the camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a camera is mounted on a head-worn display to capture images of objects, then the user can view captured images, but the device complexity and weight increase due to additional mounting structures and components
Solution Approach 1:
The camera is integrated directly into the head-mounted display device, merging the imaging function with the display structure. This eliminates the need for separate mounting structures and reduces overall device complexity while maintaining image capture capability.
Solution Approach 2:
The head-mounted display device is designed to perform multiple functions including displaying information and capturing images through an integrated camera. This multi-functionality approach eliminates the need for separate dedicated imaging devices, reducing overall system complexity.
2Loss of information
If a camera is mounted on a head-worn display to capture images of objects, then the user can view captured images, but the weight of the device increases due to additional components
Solution Approach 1:
The camera is integrated directly into the head-mounted display device, merging the imaging function with the display structure. This eliminates the need for separate mounting structures and reduces overall device complexity while maintaining image capture capability.
3Loss of time
If images are captured and displayed in real-time with minimal processing delay, then the user experience is improved, but the processing speed and computational requirements must be increased
Solution Approach 1:
The system performs preliminary processing of image data by extracting key features and characteristics before full display. This preliminary action reduces the amount of data requiring real-time processing, thereby reducing processing delay while managing computational power requirements efficiently.

AI summary
A method for projecting objects by means of a projection device (11) of a vehicle is specified, wherein the projection device (11) is designed to project a projection object within an adjustable projection field (200) that is at least partly detectable by a field of view (100) of a vehicle camera (20), and wherein the method comprises a determination of a target projection field for the purpose of setting the adjustable projection field (200) and adjusting the protection field (200) in accordance with the determined target projection field. Determining the target projection field comprises a detection (400) of at least one current operating parameter of the vehicle (1) and a determination (500) of a first target projection field that corresponds to at least one operating parameter and a verification (550) as to whether a residual field of view (300) of the vehicle camera (20) that remains free from the target projection field would satisfy a predefined sufficiency criterion for the detection of a surround by the vehicle camera (11). If the sufficiency criterion is not satisfied, then a second corrected target projection field is determined on the basis of the first target projection field and on the basis of the sufficiency criterion and this second corrected target projection field is used to set the projection field (200). A device (10) for projecting objects is also specified.
