The invention provides a track deduction correction evaluation method, a terminal and a storage medium. The method comprises the following steps: obtaining a coordinate transformation matrix between an odometer and a map; setting confidence coefficient evaluation parameters by setting at least three confidence coefficient evaluation indexes including but not limited to parking space line parallelism, the linear evidence accumulation number and a linear evidence distribution variance, and evaluating the coordinate transformation matrix between the odometer and the map by using the confidence coefficient evaluation indexes; and judging the confidence coefficient of the coordinate transformation matrix, if the confidence coefficient is higher than a rated confidence coefficient of a vehicle-mounted system, correcting by adopting a track deduction correction result, and if the confidence coefficient is lower than the rated confidence coefficient of the vehicle-mounted system, ignoring thetrack deduction correction. According to the invention, an image signal is introduced to observe the target parking space in real time, the observed result is compared with the position of the targetparking space speculated by the DR, the error of the DR is given, and the error of the DR is evaluated by the confidence coefficient.
Description
technical field [0001] The invention relates to the technical field of automotive electronics, in particular to an evaluation method, terminal and storage medium for track derivation correction. Background technique [0002] Among the existing technologies, "Auto Valet Parking" (Auto Valet Parking) has become one of the hot technologies in the field of autonomous driving, and it will also be an important milestone on the road to mass production of autonomous driving. As a complete autonomous driverless car system, the AVP system drives the car at a low speed or parks the car in a limited area, such as a parking lot or surrounding roads. In addition, as a function extension of parking assistance, it will also be one of the first commercialized fully automatic driving functions. [0003] During the parking process, the signal that the vehicle relies on for path planning and positioning is track deduction (DR). Due to various uncontrollable factors, the DR signal has obvious c...
