How to Transform of coordinate of actors from vehicle coordinate to world coordinate or refference coordinate system (ADAS toolbox) …?
egoWaypoints = ; % ego vehicle waypoints wrt world coordinate.
egoAngle = atan(diff(egoWaypoints(:,1))./diff(egoWaypoints(:,2)));
egoAngle(end+1) = egoAngle(end);
tempX = ; % X coordinate wrt to Vehicle coordinate system from sensor fusion
tempY = ; % Y coordinate wrt to Vehicle coordinate system from sensor fusion
relX = tempX.*sin(abs(egoAngle(1:length(tempX))))-tempY.*cos(abs(egoAngle(1:length(tempX))));
relY = -tempX.*cos(abs(egoAngle(1:length(tempX))))-tempY.*sin(abs(egoAngle(1:length(tempX))));
absX = egoWaypoints(1:length(tempX),1)+relX;
absY = egoWaypoints(1:length(tempX),2)+relY;
