Millimeter-wave insect vision sensors for collision avoidance in space
A novel collision avoidance sensor with possible application in satellite navigation is presented. Passive radiometric detection of colliding objects is used, offering the advantage that it does not interfere with satellite communication or guidance systems. Operation in the millimetre-wave band allows the possibility of full scale integration of front-end detection circuitry with the back-end ...
متن کاملCharacterisation of Insect Vision Based Collision Avoidance Models Using a Video Camera
Insects have very efficient vision algorithms that allow them to perform complex manoeuvres in real time, while using a very limited processing power. In this paper we study some of the properties of these algorithms with the aim of implementing them in microchip devices. To achieve this we simulate insect vision using our software, which utilises the Horridge Template Model, to detect the angu...
متن کاملBroadband millimetre-wave passive spatial combiner based on coaxial waveguide
A broadband millimetre-wave passive spatial combiner using a microstrip probe array and an oversized coaxial waveguide is successfully designed and tested. The equivalent circuit approach of transverse electromagnetic (TEM) lines is adopted to synthesise the coaxial stepped impedance transformer from a K connector with the oversized coaxial waveguide and to analyse the microstrip probe array. T...
متن کاملComputer-Vision Based Collision Avoidance for UAVs
This research is investigating the feasibility of using computer vision to provide robust sensing capabilities suitable for the purpose of UAV collision avoidance. Presented in this paper is a preliminary strategy for detecting collision-course aircraft from image sequences and a discussion on its performance in processing a real-life data set. Initial trials were conducted on image streams fea...
متن کاملVision Based Collision Avoidance of Industrial Robots
This article presents an approach to collision avoidance of industrial robots. It is based on the method of artificial potential or force fields. The field is generated by virtual charges which are placed on obstacles. The virtual force acts on the robot which results in the modification of the manipulator path to avoid collisions. Robot path modification is performed by means of impedance cont...
