Compared with a single indicator evaluation, the present invention comprehensively considers multiple evaluation indicators and can more comprehensively evaluate the quality of roadside perception data.
[0081] like Figure 2 The figure shows a workflow diagram of a method for evaluating quality of intelligent connected roadside perception data in another embodiment of the present invention, including:
[0082] Step S201, obtaining a set of quality evaluation indicators for intelligent connected roadside perception data, wherein the set of quality evaluation indicators for intelligent connected roadside perception data includes multiple types of evaluation indicators for different road locations, different manufacturers, different roadside perception devices, and different time periods.
[0083] Step S202, normalizing and judging the evaluation indicators in the intelligent connected roadside perception data quality evaluation indicator set:
[0084] If the evaluation index is a pass rate, the pass rate is used as a normalized evaluation index;
[0085] If the evaluation indicator is not the pass rate, and the evaluation indicator is a positive evaluation indicator, the positive evaluation indicator is normalized to a normalized value between 0 and 1 as the normalized evaluation indicator;
[0086] If the evaluation indicator is not the pass rate, and the evaluation indicator is a negative evaluation indicator, the evaluation indicator is converted into a positive evaluation indicator, and the converted evaluation indicator is normalized to a normalized value between 0 and 1 as a normalized evaluation indicator.
[0087] Step S203, based on the normalized indicator set, calculate the comprehensive evaluation index of the roadside perception data quality in the roadside perception device dimension, and identify the roadside perception device with the best roadside perception data quality.
[0088] Step S204, based on the normalized indicator set, calculate the comprehensive evaluation index of the roadside perception data quality in the manufacturer dimension, and identify the manufacturer with the best roadside perception data quality.
[0089] Step S205, based on the normalized indicator set, calculate the comprehensive evaluation index of the roadside perception data quality in the road position dimension, and identify the road position with the best roadside perception data quality.
[0090] Specifically, first execute step S201 to obtain a set of quality evaluation indicators for intelligent connected roadside perception data, wherein the set of quality evaluation indicators for intelligent connected roadside perception data includes multiple types of evaluation indicators for different road locations, different manufacturers, different roadside perception devices, and different time periods.
[0091] Specifically, the intelligent connected roadside perception data quality evaluation index set includes multiple evaluation indicators, including the track survival cycle qualification rate, speed qualification rate, etc., as well as the maximum value of the effective perception range, offline time, and number of offline times.
[0092] In some embodiments,

[0094] It represents the speed qualification rate of equipment d of manufacturer j at road position i in the kth time period;
[0095] …
[0096] It represents the maximum effective sensing range of device d of manufacturer j at road location i in the kth time period;
[0097] It indicates the offline time of the sensing device of manufacturer j at road location i in the kth period;
[0098] It represents the number of offline times of the sensing device of manufacturer j and device d at road location i in the kth time period;
[0099] The above indicators form the intelligent network roadside perception data quality evaluation index set, which is represented by I i,j,d,k It represents the quality evaluation index set of intelligent connected roadside perception data of manufacturer j device d at road location i in the kth period, that is,
[0100]
[0101] Then, step S202 is executed to normalize the evaluation indicators in the intelligent connected roadside perception data quality evaluation indicator set:
[0102] If the evaluation index is a pass rate, the pass rate is used as a normalized evaluation index;
[0103] If the evaluation indicator is not the pass rate, and the evaluation indicator is a positive evaluation indicator, the positive evaluation indicator is normalized to a normalized value between 0 and 1 as the normalized evaluation indicator;
[0104] If the evaluation indicator is not the pass rate, and the evaluation indicator is a negative evaluation indicator, the evaluation indicator is converted into a positive evaluation indicator, and the converted evaluation indicator is normalized to a normalized value between 0 and 1 as a normalized evaluation indicator.
[0105] Specifically, if the evaluation index is a qualified rate (such as the track survival period qualified rate, speed qualified rate, etc.), the value is between 0 and 1, and no normalization is required. The qualified rate is directly used as the normalized evaluation index;
[0106] If the evaluation index is not the pass rate, and the index is a positive evaluation index (such as the maximum value of the effective perception range), it is directly normalized to a normalized value between 0 and 1 as the normalized evaluation index.
[0107] If the evaluation indicator is not the pass rate, and the indicator is a negative evaluation indicator (such as offline time and number of offline times), it is necessary to first convert the indicator into a positive evaluation indicator, and then normalize it to a normalized value between 0 and 1 as a normalized evaluation indicator.
[0108] Specifically, positive indicators are needed to evaluate the optimal equipment, manufacturer, and road section location.
[0109] In some embodiments, the positive evaluation indicator includes a maximum effective perception range;
[0110] If the evaluation indicator is not the qualified rate, and the evaluation indicator is a positive evaluation indicator, the positive evaluation indicator is normalized to a normalized value between 0 and 1, including:

[0114] In one embodiment, converting the evaluation index into a positive evaluation index includes: calculating a set threshold value minus the evaluation index to obtain a converted evaluation index.
[0115] Specifically, when the evaluation indicator is a negative evaluation indicator, the set threshold is calculated to subtract the evaluation indicator to obtain a converted evaluation indicator, and the converted evaluation indicator is a positive evaluation indicator.
[0116] In some embodiments, the negative evaluation indicator includes offline time. By setting a threshold and subtracting the offline time, the converted evaluation indicator obtained is the online time, which is a positive evaluation indicator.
[0117] In some embodiments, the negative evaluation index includes the number of offline times. By setting a threshold value and subtracting the number of offline times, the converted evaluation index obtained is the number of online times, which is a positive evaluation index.
[0118] In some embodiments, if the evaluation indicator is not the pass rate and the evaluation indicator is a negative evaluation indicator, converting the evaluation indicator to a positive evaluation indicator, and normalizing the converted evaluation indicator to a normalized value between 0 and 1, includes:
[0119] For each offline duration, the offline duration is converted into a positive evaluation indicator using the following formula and then normalized to a normalized value between 0 and 1:
[0120]
[0121] In the formula, It represents the offline time of the roadside sensing device of manufacturer j and device d at road location i in the kth period, represents the normalized value of the offline time converted into a positive evaluation index, K represents the number of time periods within the time period T, and N rcu represents the number of roadside sensing devices, θ t Indicates the threshold for setting the online and offline time. For example, when each time period is 1 hour, θ t = 3600 seconds;
[0122] For each offline count, the following formula is used to convert the offline count into a positive evaluation indicator and then normalized to a normalized value between 0 and 1:
[0123]
[0124] In the formula, It represents the number of times the roadside sensing device of manufacturer j and device d at road location i is offline in the kth period. Represents the normalized value of the number of offline times converted to a positive evaluation index. n Indicates the threshold value for the number of online and offline times. For example, when each time period is 1 hour, θ n =60 times.
[0125] Specifically, the maximum effective sensing range The normalization method is as follows:
[0126]
[0127] In the formula, express The normalized value of K represents the number of time periods within the duration T, N rcu Indicates the number of sensing devices.
[0128] For the two negative evaluation indicators, offline time and offline times, the negative evaluation indicator is subtracted from the set threshold to obtain the positive evaluation indicator. This is equivalent to converting the offline time into the online time within the set time range, and converting the offline times into the online times within the set times range. If the offline time and offline times exceed the set threshold, they are directly set to 0.
[0129] Offline time The normalization method is as follows:
[0130]
[0131] In the formula, Represents the normalized positive evaluation index of offline time, that is, the normalized value of offline time converted into positive evaluation index (online time within the set time range). θ t Indicates the threshold for setting the online and offline time. For example, when each time period is 1 hour, θ t =3600 seconds.
[0132] Offline times The normalization method is as follows:
[0133]
[0134] In the formula, Represents the normalized positive evaluation index of offline times, that is, the normalized value of the offline times converted into the positive evaluation index (the online times within the set times range). θ n Indicates the threshold value for the number of online and offline times. For example, when each time period is 1 hour, θ n =60 times.
[0135] The duration T is the total test duration for determining the evaluation index. The duration T is divided into K time periods, and an evaluation index is determined for each time period k.
[0136] Finally, the above normalized indicators are combined into a normalized indicator set, where different road locations, different manufacturers, different equipment, and different time periods are combined, and each combination corresponds to a normalized indicator set. Represents the normalized indicator set of road location i, manufacturer j, equipment d at time period k. For example:
[0137]
[0138] Let x represent the normalized index set The xth index, N I Represents the normalized index set The number of indicators included. For example, in this embodiment, when x=1, When x=2, ...; when x = N I hour,
[0139] This embodiment proposes corresponding normalization methods for different evaluation indicators.
[0140] Then, execute steps S203-S205, calculate comprehensive evaluation indicators of roadside perception data quality in multiple dimensions based on the normalized indicator set, and identify the roadside perception equipment with the best roadside perception data quality, the manufacturer with the best roadside perception data quality and / or the road location with the best roadside perception data quality based on the comprehensive evaluation indicators of roadside perception data quality in multiple dimensions.
[0141] Among them, step S203 to step S205 are parallel steps.
[0142] Specifically, step S203 is performed to calculate the comprehensive evaluation index of the roadside perception data quality in the roadside perception device dimension based on the normalized index set, and identify the roadside perception device with the best roadside perception data quality.
[0143] In one of the embodiments, the calculating of the comprehensive evaluation index of the roadside perception data quality in the roadside perception device dimension based on the normalized index set, and identifying the roadside perception device with the best roadside perception data quality, includes:
[0144] Calculate a first roadside perception data quality evaluation index set in the roadside perception device dimension for each roadside perception device of each manufacturer at each road position, wherein each of the first roadside perception data quality evaluation index sets includes, in the normalized index set, an average value of similar normalized evaluation indicators of the roadside perception devices corresponding to the manufacturer corresponding to the road position corresponding to the first roadside perception data quality evaluation index set within a time length T;

Each of the first roadside perception data quality evaluation index sets includes the normalized index set, and the average value of the same normalized evaluation index of the roadside perception device corresponding to the manufacturer corresponding to the road position corresponding to the first roadside perception data quality evaluation index set within a time length T.
[0158] Among them, the average value of the same type of normalized evaluation indicators of the roadside perception device corresponding to the manufacturer corresponding to the road position corresponding to the first roadside perception data quality evaluation indicator set within the time length T refers to: the normalized evaluation indicators of all time periods of the same type of the roadside perception device corresponding to the manufacturer corresponding to the road position corresponding to the first roadside perception data quality evaluation indicator set within the time length T are summed and divided by the number of time periods.
[0159] For example, with represents the first roadside perception data quality evaluation index set in the roadside perception device dimension of manufacturer j device d at road position i within time T, K represents the number of time periods within time T, then
