- Abstract:
- This paper addresses the problem of recognition and identification of objects with an IR diode array, working on a reflection light scanner principle. Essentially two arrays comprising of 3 emitter-receiver pairs are mounted on two sides of the area of inspection, enabling the estimation of the size of the object in different dimensions and reducing the requirements with regard to the detection range. The sensors are driven successively in time, hence no signal overlapping and cross-talk occur. For the recognition, a neural network approach based on the Backpropagation algorithm has chosen. The array data are preprocessed via a Principal Components approach. As a result various objects can be recognised and classified easily and are well separable from other echoes. This work is preliminary for a practical system determining the number of people and identifying people getting into or out of a room and other applications supporting important home appliances like occupation-driven HVAC control or determining behaviour patterns.
