Handheld Optical Dimensioning Device for Planar Surfaces

The patent divides the dimensioning task into multiple independent measurements. Instead of using a complex overhead scanner that captures everything at once, the system uses multiple simple rangefinders positioned at different locations to measure specific points on the target surface independently. Each rangefinder measures the distance to a specific point, and these individual measurements are then combined to determine overall dimensions.

The patent introduces a coordinate transformation matrix as an intermediary element. This matrix serves as a mediator that converts the simple distance measurements from multiple rangefinders into accurate dimensional information about the target surface. The matrix handles the complex geometric relationships and coordinate transformations, allowing simple measurement devices to achieve precise dimensioning results.

The patent performs preliminary positioning of rangefinders at known locations before actual measurement. By pre-establishing the positions and orientations of multiple rangefinders, the system eliminates the need for time-consuming real-time calibration and alignment during the dimensioning process. The pre-configured system can immediately begin taking measurements once activated.

The system uses the target surface itself as a reference for measurement. By projecting light patterns or using the target's own geometric features as reference points, the system eliminates the need for external reference objects or complex calibration procedures. The target surface serves its dual purpose as both the object being measured and the reference framework for the measurements.

The patent creates a virtual copy or digital model of the target surface through multiple distance measurements. Instead of requiring the operator to physically measure and calculate dimensions manually, the system captures the geometric information and creates a digital representation that can be processed automatically. This digital copy preserves all dimensional information while eliminating the complexity of manual measurement procedures.

The patent replaces manual mechanical measurement procedures with optical and electronic systems. Instead of requiring physical tape measures, rulers, or manual calculations, the system uses rangefinders, light sources, and computational algorithms to automatically determine dimensions. This substitution eliminates the physical labor and complexity of traditional measurement methods while maintaining or improving precision.
