BIAS ESTIMATING METHOD FOR A TARGET TRACKING SYSTEM

The present invention is in general related to automatic alignment in multisensor target tracking. The process of the invention repeatedly generates estimates for sensor bias errors (b) by minimising a function, given on one hand by the magnitude of the discrepancy between measurements (M) and a measuring model, where the measuring model is a function of the unknown target location and unknown bias parameters, and on the other by the bias parameters and their predetermined statistical distributions (15). In a preferred embodiment of the present invention, the minimising step is performed by linearising components of the function around an approximate target position (normally obtained from the tracker (10)) and around nominal (typically zero) bias errors, and the function is subsequently minimised with respect to target positions as well as to the bias parameters (b). In addition, possible time dependence of the bias parameters are modelled by the incorporation of process noise.

Calibrating target projector in image display apparatus

Apparatus 2 for displaying an image eg on the inside of a dome 15 has a target projector 4 and self-calibration means (6, fig 2) comprising reference means 8 for giving a known angular reference, and an optical sensor (10) which is positioned to have an optical path in common with the target projector 4 and thus has an optical path 12 to the reference means 8. In use the target projector 4 steers to a predetermined azimuth/elevation, the sensor (10) views the reference means 8 and compares its position with the expected position, and any error is used in a homing algorithm order to effect self-calibration. The target projector may project a spot in the centre of its optical path so that the sensor can compare the positions of this spot and the reference means. The optical paths of the projector and the sensor may be joined through a beam splitter/combiner.

Image-data reduction technique

First processing means 202 converts a high-resolution, wide field of view image signal into a series of output signals, ranging in resolution from high resolution, L0, to low resolution, GN, representing the same field of view. These signals, except for GN, are further processed by second processing means 204-0 to 204-(N-1) to produce final output signals ranging in field of view from a low resolution image of the entire field of view, GN, to a highest resolution image of a selectably positionable smallest spatial sub-region of the entire field of view, L'0 (see Figure 5). The arrangement is such that each of the final output signals L'0-LN-1, GN comprises the same number of pixels. This eases subsequent computing requirements.

Subject tracking apparatus

A subject tracking apparatus in which the target is tracked further stably by effectively eliminating the erroneous judgment due to the effects from the object which resembles the target, the luminance change, and objects having different shapes. Each of the R-Y signal and the B-Y signal at setting the feature of target is modeled by the luminance, so as to detect the features without concerning the hue to the luminance change. Also, the R-Y signal and the B-Y signal are directly modeled, so as to detect the features in the same way regarding the subject with colorless since hue has no effect on it. Since it becomes unnecessary to adjust the parameter strictly by modeling in regard to the permissible error, the target can be tracked stably even the luminance changes.

Method for single-position determination of location of optical radiation source

Изобретение относится к области определения местоположений источников оптического излучения и касается способа однопозиционного определения местоположения источника оптического излучения. Способ включает в себя координатную привязку фотоэлементов матричных фотоприемников двух оптико-электронных координаторов, прием излучения источника оптического излучения двумя оптико-электронными координаторами и определение координат фотоэлементов, сигналы на выходе которых превысили пороговое значение. Оптико-электронные координаторы с матричными фотоприемниками располагают на минимальном расстоянии друг от друга так, что их приемные плоскости находятся в одной плоскости. Координаты местоположения источника оптического излучения вычисляют по значениям координат фотоэлементов, сигналы на выходе которых превысили пороговое значение, значениям параметров оптической системы оптико-электронных координаторов и по параметрам взаимного положения центральных фотоэлементов оптико-электронных координаторов. Технический результат заключается в обеспечении возможности однопозиционного определения местоположения источника оптического излучения, упрощении способа и увеличении дальности обнаружения сигналов. 2 ил.
