Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for configuring laser scanner monitoring zones are complex, requiring trained personnel and specialized equipment, making them impractical for easy and quick configuration, especially in difficult-to-reach locations and for defining complex geometries.
Innovation Solution
A simplified method using a wireless remote controller to input vertex points directly to the laser scanner, allowing users to define monitoring zones without complex software or specialized training, by capturing and recording coordinate positions relative to the scanner, enabling intuitive and precise configuration of two- or three-dimensional zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional configuration methods using graphical user interface and specialized software are used, then monitoring zone configuration can be achieved, but the process becomes complex and requires trained personnel
Solution Approach 1:
A wireless remote controller is introduced as an intermediary device between the user and the laser scanner. The remote controller captures images via its camera, processes coordinate information, and transmits configuration data to the scanner, eliminating the need for complex software interfaces and specialized equipment while maintaining configuration accuracy
Solution Approach 2:
The patent replaces the mechanical/software-based configuration system (graphical user interface, computer software, specialized equipment) with an optical-based system using the remote controller's camera to capture images and automatically extract coordinate information, simplifying the configuration process
2Manufacturing precision
If conventional configuration methods are used, then monitoring zones can be defined, but specialized equipment and trained personnel are required
Solution Approach 1:
The remote controller performs self-service by automatically capturing images, processing coordinate data, and transmitting configuration information to the laser scanner without requiring external specialized equipment or trained personnel, making the system easy to operate while maintaining precision
Solution Approach 2:
The wireless remote controller serves multiple functions: it acts as an image capture device, a coordinate processing unit, and a communication interface, replacing multiple specialized tools with a single universal device that anyone can operate
3Ease of manufacture
If direct coordinate input method is used, then simple geometries can be configured, but complex geometries and difficult-to-reach locations cannot be handled
Solution Approach 1:
The patent transitions from direct coordinate input (one-dimensional data entry) to image-based configuration (two-dimensional visual capture). By capturing images with the remote controller's camera, the system can define complex geometries in two dimensions and automatically extract coordinate information, enabling configuration of any geometry type regardless of location accessibility

AI summary
The disclosure relates to a method for simplifying the configuration process of setting monitoring zones for a laser scanner. The method includes activating (102) a configuration mode of the laser and sampling (104) a field of view to establish a frame of reference including the target item to be monitored and other static items present in the field of view. To configure the monitoring zone, an operator may enter (106) the area and sends (110) signals to the laser scanner via a remote controller at a variety of vertex points. The signals for each of the vertex points are thereafter analyzed (118) by the laser scanner to determine positional data and establish the boundaries of the monitoring zone for the laser scanner.
