New requirements are put forward for the commander's gesture recognition when driving tanks and armored vehicles. Image-based gesture recognition technology is vulnerable to illumination and easy to expose. A gesture recognition method based on laser radar is proposed. The palm motion posture is judged by analyzing the distance and angle information of the received hand points. The experimental results show that the gesture recognition method based on laser radar has the advantages of low cost of system construction and is not affected by light. The communication between night tanks, armored vehicle drivers and commanders provides new technical means.
Laser command guidance system transmits commands via pulsed laser, which has the advantages of long transmission distance and high reliability. In this paper, the error correction encoding method during the transmission of pulse command is analyzed and verified through experiments on the laser command guidance system. The experimental system consists of a controller, an encoded laser transmitter, a laser receiver and decoder, a solution drive and a data collector. The basic principle of Hamming code which can realize the detection of 2 error codes on the basis of 1 error code corrected is also analyzed. Experiments of laser command transmission, reception and decoding carried out on the experimental system validated the feasibility and error correction accuracy of the experimental system.
