Formula C:T=(ΣJn-ΣJ1n -ΣJ2n)/n;
During the above is various, n=m >=3.
The present embodiment as a example by 5 points, i.e. n=m=5.The various of each size is then calculated to be respectively:
L= V*(S12+S12+S13+S14+S15+S21+S22+S23+S24+S25)/10;
H=(W1+W2+W3+W4+W5-(W11+W12+W13+W14+W15 +W21+W22+W23+W24+W25)/5;
T=(J1+J2+J3+J4+J5-(J11+J12+J13+J14+J15+J21+J22+J23+J24+J25)/5.

Obtain by other means, however it is not limited to this.
After measuring the size of various point locations, either any size in length, width and thickness, directly can further judge
Whether battery is qualified, and determination step is:Preseting length, width and upper thickness limit or lower limit;Compare the length of each position for calculating
The upper limit or lower limit of any size and correspondingly-sized in degree, width and thickness;Length, the width of each hole site that judgement is calculated
Any size then judges battery as qualified in the upper limit or lower limit allowed band in degree and thickness, each hole that judgement is calculated
The length of position, width and any size exceeds the upper limit or lower limit allowed band in thickness, then judge battery as unqualified.Example
Such as, existing electronic product requires thickness of thin, generally higher to thickness requirement, and such as one cell thickness is 5mm ranks, the upper limit
It is 5mm, thickness generally uses negative common difference, i.e., can not exceeds the upper limit, as long as the T that arbitrfary point position calculates1=J1-J11-J21>
5mm, then judge that the battery is unqualified.And length and width can use plus tolerance, as long as the L that arbitrfary point position calculatesnAnd Hn
Beyond 0.5mm, then judge battery as unqualified.It should be appreciated that data above only for citing, actual conditions as needed depending on.
These are calculated and decision can all be realized by the corresponding function module in data processing equipment.Specifically, data processing
Device is also connected with a display device, and so as to display data and test mode, underproof battery may be set to type of alarm, and
Can further be counted, to calculate disqualification rate.Therefore, test system also can be set a warning device such as alarm, with
And calculator.
It is further preferred that as described in test system, it is fixed to be respectively provided with the both sides up and down of battery 20 and the left and right sides
Bit unit 16, each laser head 14,15 is installed on setting element 16 according to regular polygon or linear array, positioned at the same side
