An interactive inflatable amusement structure in the form of an obstacle course or play area which incorporates audio and visual electronics at various locations within the obstacle course through the use of a plurality of transmitter / receivers in radio frequency communication with a central control unit for transmitting data such as elapsed time and points, the central control unit positioned at the egress to the inflatable structure proximate the start of the obstacle course or inflatable game, bounce, etc., and the transmitter / receivers positioned within pockets or the like formed at various locations on the inflatable obstacle course structure.

The invention discloses an obstacle avoidance method and device, comprising: acquiring a first specific position of the obstacle if an obstacle is detected during the running of an automatic driving vehicle; determining the position of the obstacle and the vehicle body according to the first specific position The current distance; through the current distance, determine the four coordinate points of the area where the obstacle is located when the body safely avoids the obstacle; based on the four coordinate points, use the Bessel formula to calculate the obstacle avoidance path. Judging whether the driving road is smooth by detecting whether there is an obstacle, determining the current distance from the vehicle body according to the position of the obstacle, determining the coordinate point according to the current distance, and then calculating the obstacle avoidance path according to the coordinate point, the Bessel formula is compared with the existing technology The calculation method and amount of calculation in the algorithm are relatively small, so when an obstacle is detected, the computer can calculate the path around the obstacle in a short time to avoid traffic accidents.

An artificial cave has various features that resemble speleothems (e.g., stalactites, stalagmites, etc.) found in real subterranean caves. Human users may pass through the artificial cave, with each user wearing a wearable transceiver that broadcasts a signal code unique to that user. Fixed transceivers throughout the cave can detect and identify any user who is sufficiently close to that fixed transceiver. Other components of the system collect user identification information from the fixed transceivers for any of several possible purposes (e.g., identifying which user was probably responsible for inappropriate interaction with a speleothem that is adjacent to a given fixed transceiver, where all of the various user of the cave are currently located in the cave, etc.). A count of users currently in the artificial cave passageway may be maintained and used for a number of purposes. Similarly, human detectors may be employed near the system and / or in the artificial cave passage for any of several different purposes.

The invention discloses a method and device for calculating the course angle of an obstacle based on time synchronization. Wherein, the method includes: obtaining a heading angle calculation model, wherein the heading angle calculation model is obtained by training the historical data of the heading angle yaw value; sensing obstacles through a sensing device to obtain heading angle perception data; according to the heading angle The angle perception data and the heading angle calculation model are used to generate a first heading angle calculation result; and the verification operation of the synchronization time stamp is performed on the heading angle calculation result to obtain a second heading angle calculation result. The invention solves the problem that in the perception detection algorithm of the prior art, it is difficult to calculate the yaw angle of obstacles using image perception, and the result is also difficult to be accurate; it is not easy to calculate the yaw angle of obstacles accurately by using the traditional point cloud clustering algorithm , and stability cannot be guaranteed. Secondly, the calculation of the obstacle heading angle also involves the own vehicle heading angle output by the inertial navigation of the own vehicle, the calibration results of the inertial navigation and perception sensors, and the time synchronization of the sensors, which is a technical problem involving systematic problems of software, hardware and algorithms. .
