Everyone knows that if the computer cannot load the driver, the device may not work properly or interact with the computer correctly. So how do we solve the problem when a prompt box pops up on the computer that the driver cannot be loaded on this device? The editor below will teach you two ways to easily solve the problem.　Unable to load the driver on this device Solution 1. Search for "Kernel Isolation" in the Start menu. 2. Turn off Memory Integrity, and it will prompt "Memory Integrity has been turned off. Your device may be vulnerable." Click behind to ignore it, and it will not affect the use. 3. The problem can be solved after restarting the machine.

Written above & the author’s personal understanding: At present, in the entire autonomous driving system, the perception module plays a vital role. The autonomous vehicle driving on the road can only obtain accurate perception results through the perception module. The downstream regulation and control module in the autonomous driving system makes timely and correct judgments and behavioral decisions. Currently, cars with autonomous driving functions are usually equipped with a variety of data information sensors including surround-view camera sensors, lidar sensors, and millimeter-wave radar sensors to collect information in different modalities to achieve accurate perception tasks. The BEV perception algorithm based on pure vision is favored by the industry because of its low hardware cost and easy deployment, and its output results can be easily applied to various downstream tasks.
