Embodiment

[0024] refer to Figure 1-3 , taking the millimeter wave obstacle detection system as an example, the millimeter wave obstacle detection sensor generates a batch of data every 80 milliseconds.

[0025] The target trajectory tracking processing method proposed by the present invention sets a data buffer in the memory of the processing unit of the millimeter-wave obstacle detection system, and adopts the method of circular queue. The buffer size is set according to the amount of radar data frames that need to be stored. If the data needs to be stored for 5 seconds of radar historical data, the buffer can be set to the size of one frame of data * 65. The data acquisition and sorting module is responsible for storing the data sent by the sensor into the circular queue in turn, the new data covers the oldest data in turn, and always keeps the current data stored in the circular queue, as well as the data 5 seconds before the current moment.

[0026] After the data acquisition and ...

Abstract

The invention discloses a target trajectory tracking processing method based on a buffer technology, which relates to the technical field of data processing. In view of the problem that existing functions are difficult to achieve, the method in the scheme comprises the following steps of using a transmitting antenna to transmit data and a sensor to receive the data, putting signals reflected by the target object data received by the sensor within a certain period of timeinto a corresponding number storage space according to a target number,and storing in a receiving order, and filling timestamps. The method is convenient to use; in a data buffering mode, the influence of interference factors on the obstacle avoidance system is solved by using a software method,high anti-interference radarequipment does not need to be selected, extra multi-system sensor equipment does not need to be added to achieve data fusion, the difficulty required for function implementation is reduced, copying can be conveniently conducted, portability is achieved, popularization in a large range is facilitated, the technical requirement and the production cost are reduced, and tracking implementation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a target trajectory tracking processing method based on buffering technology. Background technique [0002] In the field of automatic control systems involving major personal and equipment safety, the system is required to have extremely high security, the detection radar installed at the front end of the system is required to detect targets, and the system is required to analyze and process the targets detected by the radar in a timely and efficient manner. , so as to determine whether the target poses a threat to the current equipment, and then take corresponding evasion measures. For this reason, the obstacle avoidance system based on radar wave emerges as the times require. Taking the millimeter-wave radar obstacle avoidance system as an example, the high-frequency millimeter-wave is transmitted through the transmitting antenna. After being reflected by the target, t...
