What are the current advancements in computer vision technology for vehicle detection?5 answersCurrent advancements in computer vision technology for vehicle detection include the use of deep learning algorithms such as Convolutional Neural Networks (CNN) and the integration of other techniques like long short-term memory (LSTM) modules and background subtraction (BS) methods. CNN-based two-stage and one-stage object detection algorithms have become mainstream, but they have limitations in terms of the global receptive field. To overcome this, researchers have explored the use of Transformer models, which show strong long-distance dependence characteristics. YOLO v4 and YOLOv5s architectures have been employed for real-time vehicle detection with high precision scores. Additionally, the combination of object detectors with LSTM modules has been proposed to improve detection performance in various conditions. Another approach involves using a BS-based module as a preprocessing step to optimize the number of convolution operations executed by the CNN module, reducing computational complexity without compromising accuracy. These advancements pave the way for intelligent transportation systems, autonomous vehicles, and advanced traffic applications.
What are the challenges in developing software for CCTV systems?5 answersDeveloping software for CCTV systems faces several challenges. One challenge is the need to detect and prevent potential threats in real-time surveillance, which involves managing conflicting conclusions from different sources and handling the uncertainty and reliability of the information provided. Another challenge is the human factor, where operators' abilities and considerations play a crucial role in realizing the full potential of a CCTV system.

How illegal parking can be detected in videos?5 answersIllegal parking can be detected in videos using various methods. One approach involves analyzing video frame images to detect vehicles in target no-parking areas. If a vehicle is detected, its information is extracted and compared to the information from previous frames to determine if it is parked illegally. Another method involves capturing a video stream of a scene during a vehicle trip and processing it to identify target objects such as no-parking signage and parked vehicles. The absolute locations of these objects are determined and stored, and a set of unique objects is sent to a cloud server for determining parking violations. In the case of ship illegal parking detection, a video sequence of a ship is collected and ship detection results are determined for each frame. Target tracking is performed to obtain tracking queues, and the ship is determined to be illegally parked based on these queues. Additionally, an abnormal parking detection method based on intelligent video analysis involves target detection, attribute information extraction, and comprehensive analysis to reduce false alarms and missing reports.

How to develop an advanced driving assistance system?5 answersTo develop an advanced driving assistance system, several approaches can be considered. One approach is to use a driving assistance system that includes a radar wave transmitting and receiving device, a photographing device, a processing device, and a prompting device. The radar wave device transmits and receives radar waves to detect objects, while the photographing device captures images in the same direction. The processing device calculates the position of the object and sets it as the detected object in the image. The prompting device provides information about the object's position. Another approach is to use a display and control system that provides a "Third-person" view of the car in real-time, similar to playing a video game. This system allows the driver to recognize the road condition more easily and control the car using a gamepad or other input device. Additionally, an advanced driver assistance system (ADAS) can be designed with a control assembly that includes actuating modules for the ADAS. The control module receives control signals and sensor data to execute driving assistance control operations. Furthermore, a driving assistance system can include in-vehicle devices that communicate with a roadside device to determine if a traffic signal controller prioritizes vehicles travelling in a row. Lastly, an electric power-assisted advanced driving assistance system can be developed by integrating an electric power-assisted steering system with the ADAS. This system allows for fault checking, interaction between the EPS and ADAS in angle and torque control modes, and ensures the safety and stability of the system.
