    Abstract: An example method includes receiving point cloud information about a field of view of a lidar system. The point cloud information includes spatiotemporal and amplitude information about return light received. The method also includes determining, based on the point cloud information, a set of bright light returns from at least one highly reflective object. The bright light returns include return light having an amplitude above a photon threshold and a corresponding bright light return range. The method yet further includes determining, based on the point cloud information, a set of crosstalk returns. The crosstalk returns include return light having a corresponding crosstalk return range. The method includes adjusting, based on a normalized number of crosstalk returns, at least one of: a cleaning system, an operating mode of a lidar system, or an operating mode of a vehicle.

    Abstract: An imaging system is described for generating an estimate for the virtual horizon for a moving vehicle. The estimate of the virtual horizon can correspond to lower and higher boundaries of a region within the field of regard, such that the virtual horizon is between the lower and the higher boundaries. In cases where determination of the virtual horizon may be unreliable due to traffic, weather or other road conditions that obscure the visibility in front of the vehicle the imaging system may switch to a static vertical scan density pattern having a broad central focus, which can mitigate the possibility that the system focuses on an incorrect virtual horizon and fails to capture significant objects or conditions in the roadway.

    Abstract: The subject of the invention is a system for determining the position inside objects. It is characterized by the fact that it consists of radio probes (1, 2, 3,..., n) working in Bluetooth 5 technology arranged sequentially on the perimeter of the analyzed object, each of which contains a transmitting microcontroller and a receiving microcontroller, which are connected via a transmitting microcontroller with a Bluetooth 5 expansion card (4), and this one is connected by serial connection to the central unit (5) connected to the reconstructing server (7). A method for determining the position inside objects using the system. It is characterized in that from the transmitting microcontroller of radio probes (1, 2, 3,..., n) a communication packet with the user data range up to 31 bytes is released, containing the values of RSSI indicators of other scanned devices and the TX power parameter defining the transmit power of the antenna transmitting device, while by means of receiving microcontrollers from radio probes (1, 2, 3,..., n) sent signals are received from other radio probes (1, 2, 3,..., n), from which the receiving microcontrollers calculate RSSI index for the radio probe (1, 2, 3,..., n) from which the packet was sent, and then arranges the RSSI pointers at a fixed location of the data container according to the order number of the radio probe (1, 2, 3,..., n), and all communication packets sent by transmitting microcontrollers are updated by receiving microcontrollers located on the same laminate and are sent out with the help of transmitting microcontrollers from radio probes (1, 2, 3,..., n) working in the Bluetooth technology 5 arranged successively on the perimeter of the analyzed object, a radio signal with a communication packet with a user data range of up to 31 bytes is transmitted, and at irregular intervals it is scanned by the central unit (5), in which after receiving the data, the identification number of the transmitting microcontroller is checked and the received row is placed inside the matrix body in the position consistent with the ordinal number of the radio probe (1, 2, 3,..., n), while irregular intervals between scanning individual system elements cause independent refreshing individual rows of the matrix, while from the central unit (5) a matrix with a dimension of n x n and non-zero diagonal is sent to the reconstructing server (7) using the Apache Kafka data bus, while this data bus does not introduce any changes in the message and without disturbing the data structure and them to algorithms using Tikhonov regularization, Gauss-Newton method, the method of contour sets and artificial intelligence mechanisms, while the reconstruction based on the background matrix and the measurement matrix is presented in the form of a heat map in one of the server services (7).
