Although waymo has accumulated more than 10 million miles on open roads, waymo’s engineers still find that there are endless new autonomous driving scenarios to be solved. 1. Examples of long tail scenarios for autonomous driving Scene oneA cyclist holds a stop sign sign sign in his hand. We don’t know when it’s going to […]

1. The algorithm of histogram filter The idea of histogram filtering algorithm is that the whole state space DOM (x (T)) is divided into disjoint parts, such as, and so on Then, we define a new state space. If and only then, because it is a discrete state space, we can use discrete Bayesian algorithm […]

In the presence of measurement noise, the least squares method can strip off the influence of noise to the maximum extent and obtain the optimal solution. The autonomous vehicle is equipped with many different sensors, their measurement accuracy is different, some of them are high precision, some of which are low, and the measurement results […]

The abovementioned ordinary least squares estimation and weighted least squares estimation assume that all measurement data are collected in advance. But in practical application, the measurement data may be flow type, for example, the position measurement system continuously measures the vehicle position at the frequency of 100Hz. In the highfrequency update frequency, there are more […]

1. Taylor series expansion If the function $f (x) $is at point $x = X_ If 0 $has any order derivative, then $$ \begin{aligned} f(x)=&\sum_{n=0}^{\infty} \frac{f^{(n)}(x_0)}{n!} (x – x_0)^n \\ =& f(x_0) + f(x_0)^{\prime}(xx_0) + \frac{f^{\prime \prime}(x_0)}{2!}(xx_0)^2 + … + \frac{f^{(n)}(x_0)}{n!} (x – x_0)^n \end{aligned} $$ Called $f (x) $at point $X_ Taylor series at […]

At present, auto parts supply chain, as a big blue ocean of automobile aftermarket, has become a “must contend place” for many businesses. The VIN code, that is, the frame number, is the only ID card of a car. From the time the car leaves the factory, sells in the 4S shop, registers the driving […]

At present, automobile ferry is a kind of ferry specially used for transporting cars. Vehicles need to buy “boarding tickets” for vehicles before boarding. However, some owners always evade tickets in order to save money. The traditional way to check tickets is to manually register the license plate number of vehicles, and then check them […]
