To compare in twos from the data order that magnetometric sensor collects in a certain image data time period order; When comparing, when the difference of two adjacent datas during greater than the saltus step threshold value, next data that data after leaning in two adjacent datas are adjacent are compared, if also greater than described saltus step threshold value, then grasp through twice comparison difference all greater than the data of saltus step threshold value, otherwise do not grasp and abandon the data that keep; When the difference of two adjacent datas is not more than the saltus step threshold value, forward data in these two adjacent datas are abandoned, the data after leaning on and next data are compared.
Alternatively, the data based calibration value change threshold after the described second screening module is arranged to will sort in such a way divides into groups, and filters out to contain one group of maximum data of data:
With reference data and with the difference of reference data less than all data of described calibration value change threshold as one group of data, described reference data after for ordering first data or the data adjacent with last data of last group of data.
Alternatively, the image data time period is determined according to the parking stall operating position, if a certain parking stall vehicles passing in and out is more frequent, what then this time period can arrange lacks relatively; If generally, vehicle can be parked the longer time after entering this parking stall, and as one day even longer time, then this time period can arrange longerly, is convenient to gather more data like this, thereby it is more accurate to make the final parking stall of determining not have the car calibration value.
For instance, the data that order collects from magnetometric sensor are: 4000,4009,4008,4001,4010,4007,4000,4002, these data are roughly analyzed, and these data minimums are 4000, are 4010 to the maximum, can illustrate that then near the value 4000 is the value under the no car state, and near the value 4010 is the value that has under the car state, then according to the line number comparison method, compares 4000 and 4009, difference then keeps 4000 and 4009 simultaneously greater than 8; Then compare 4008 and 4009, difference then abandons 4009 less than 8; Compare 4008 and 4001, difference then abandons 4008 less than 8; Compare 4001 and 4008, difference then abandons 4008 less than 8; Compare 4010 and 4001, difference then keeps 4010 and 4001 simultaneously greater than 8; Compare 4007 and 4010, difference then abandons 4010 less than 8; Compare 4000 and 4007, difference then abandons 4007 less than 8; Compare 4002 and 4000, difference is less than 8, then abandon 4000, after all comparisons are all finished, the data that keep only are left 4000,4001,4002, as seen, the data that finishing screen is selected do not have value under the car state for the parking stall substantially, and namely the alleged parking stall of the utility model does not have the car calibration value.
