There are often Apple map cars equipped with various sensors, which are specially used to collect data and enhance Apple maps. Twitter user @ yrh04e shared some of Apple’s internal information, revealing how Apple operates a special car with sensors, and the protocol Apple’s map team must follow to capture images and other data on the street. < / P > < p > Apple started with a modified van to collect data, but now the operator is driving a white Subaru cheetah called & quot; Ulysses & quot;. The vehicles belong to Apple’s 3D vision team, which is responsible for combining multiple data with computer vision and machine learning technologies to provide 3D images on Apple maps. < / P > < p > the car has been converted from dozens of hardware components, including a mounting bracket on the roof with advanced high-resolution cameras and Zeiss lenses, lidar scanners, and a 2013 Mac Pro, which can process all the collected data in real time. Everything is controlled by the eyedrive device, a modified iPad with the eyedrive application pre installed. Eyedrive can provide tasks to facilitate the operator to manage the captured data. < / P > < p > the vehicle is also equipped with 4 SSDs with 4tb capacity. In about a week, these SSDs will be filled with data. Apple relies on the ups overnight to get back these SSDs as soon as possible. The other is Lexus, which is used for apple automatic driving test. The code is " TycheEach&quot. Each converted vehicle has a dedicated version of the eyedrive application. < / P > < p > Apple keeps its modified car in a secure location, which is leased to an empty shell company to maintain the anonymity of the real owner of the vehicle. Ulysses units are usually operated by a driver and another person in charge of the eyedrive system, who receive precise instructions to collect data. < / P > < p > the team must start capturing data when the sun is at 30 degrees in the morning and keep it open until the sun reaches 30 degrees in the evening, otherwise the sun will interfere with the lidar sensor. Apple also requires that it be captured in perfect weather conditions to provide a clear and consistent image. Before field work, each vehicle is carefully inspected to ensure that all equipment is working as expected. < / P > < p > once on the road, the eyedrive app on the iPad tells the team where to drive to collect data. The operator can view the image in real time through the iPad to confirm whether the collected image is normal. The street where the car is driving will be marked with a green outline. If a street is inaccessible because it is a private area or a road under construction, the operator can mark it. < / P > < p > at the end of the day, the system will be shut down and all data will be saved safely. The car is checked again, and the SSD that collects the data is sent to Apple immediately. < / P > < p > all of this data is mainly used to enhance flyover and look around features, allowing users to explore 3D cities on Apple maps. These vehicles are common in the United States, but apple is slowly extending them to Canada, Europe and Japan. Skip to content
