Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with specific implementation methods and accompanying drawings.

[0027] Such as figure 1 As shown, the front of car A is fixedly connected with a biaxial crystal 3 and a laser generator 1 with the angle θ formed by the directions of the two optical axes. The directions of the two optical axes of the biaxial crystal 3 are represented by bold solid lines in the biaxial crystal 3 in the figure. Arrange a control circuit branch containing a photoresistor 2 at the appropriate position on the two ideal outgoing light paths behind the biaxial crystal 3, where the "ideal outgoing light path" means that when the two vehicles are in the relative position where the pose adjustment is successful, the laser The optical path of the outgoing light after passing through the crystal, and when arranging the position of the photoresistor 2, it should be considered that there is a certain misalignment between ...

Abstract

The invention discloses a light-based birefringence phenomenon pose regulation and control method, and the method comprises the following steps: (1) enabling two vehicles to stop original movement, wherein the vehicle A moves to the rear of the vehicle B and stops at a preset linear distance; (2) enabling the vehicle B to start a laser generator and rotate in situ, and forming a triangular laser signal domain between the two vehicles; (3) enabling the vehicle A to rotate towards the two sides in situ to enable the relative angle of the two vehicles to be continuously changed, if the vehicle Areaches the ideal butt joint position, receiving a signal indicating that in-place posture adjustment succeeds, enabling the vehicle A to stop rotating and sending a stopping signal to the vehicle B,and finishing the posture adjustment; (4) if not, enabling the vehicle A to translate left and right, and repeatedly executing the step (3). An optical correction device is used for replacing a computer, and the requirement for hardware equipment is remarkably reduced under the condition that the positioning posture regulation and control precision is guaranteed. Moreover, the method can provide an effective iterative initial value for the iterative algorithm accurately enough, thereby improving the convergence of the iterative algorithm, improving the convergence speed, and reducing the calculation amount of the algorithm.

Description

technical field [0001] The invention belongs to positioning navigation and control technology, in particular to a position and posture control method based on the birefringence phenomenon of light. Background technique [0002] The docking pose control technology can make two smart cars close in space and combine in structure. It is a hot issue in the research of the spacecraft and automobile industries. During the docking, the vehicle uses position tracking to perform positioning and navigation and through pose solution. Calculating and correcting one's own position is a key issue. [0003] The current related technologies mainly include image acquisition and processing technology and visual measurement computing technology. Camera-based vision sensors capture the most pristine visual images. The initial image information is converted into a digital signal by the image acquisition system, and the digital signal is sent to the image processing system and computer in turn. ...
